Full textAbstract:
This easy readible and thoroughly scientifically-backed book by australian professor Felica Jacka, explains the recent science on how diet can affect the brain and mental health, with a specific focus on the risk to anxiety and depression. The scientific evidence is drawn from the results with larger cohorts and randomized controlled trials including amongst others: ALSPAC (Avon Longitudinal Study of Parents and Children, United Kingdom); HELFIMED (Healthy Eating for Life with a Mediterranean Diet, Australia); HUSK (Hordaland Health Study, Norway); PREDIMED (Prevencíon con Dieta Mediterránea, Spain); SMILES (Supporting the Modification of Lifestyles in Lowered Emotional States, Australia). These and other studies show that wherever the geographical area, plant-based Mediterranean-like diets improve the health outcomes of children, adolescents, adults and ageing individuals affected by mental health illnesses, in cost-effective ways. Consecutive chapters illustrate recent understandings of the effects of diets on the immune system, their influence on brain plasticity (which also occurs in older humans), epigenetics, food sensitivities, inflammation, and centrally, the importance of food to the gut microbiota (including the consumption of fermented foods). These effects are explained simply and efficiently in relation to mental health, as well as briefly to psychotic illnesses, autism and ADHD. By doing so, it is possible for every physical-activity researcher or athlete interested in the combination of nutrition, lifestyles and good habits, to get up to date easily, or to make a first aquaintance with the fields of nutrition and brain health. The appendix contains a reference list that restricts itself to the most influential studies like systematic reviews and meta-analysis. Also included is the Modified Mediterranean Diet (ModiMED) food pyramid, and several ModiMEd recipies (used in the SMILES study), as well a weekly meal planner, that all could be of use to get started with an easy intervention study. Although it is intended for the general public, the book is recommended for scholars of any life sciences. With her to-the-point and easy language writing gift, professor Jacka manages to explain the complicated matters of brain health effortlessly. She does this convincingly, but not superficially, relevant and correct, without any simplification. To influence mental health through nutritious, whole foods will be an essential topic to come, also in the fields of sports. In that sense Brain Changer, can be exactly that.

Full textAbstract:
Introduction: Early childhood overweight and obesity, as a result of unhealthy dietary habits and sedentary life, is a growing global public health concern, particularly in Canada. There are limited data on how socioeconomic factors influence dietary habits of young children living in developed countries. Methods: We conducted a scoping review to examine the existing literature on how socioeconomic settings influence food consumption patterns of children 2–5 years old in developed countries. The inclusion criteria were relevant articles in the English language between 2007 and 2019. Results: From the initial 1854 articles, only 12 articles from Europe, Canada, and the United States met the inclusion criteria. There are differences in eating patterns of preschool-aged children based on parental education, whereas income level did not have a clear influence on dietary patterns. The existing studies suffer from a variety of limitations that limit a cohesive conclusion. Conclusion: Studies with children 2–5 years old are scarce. Parental education seems to influence the dietary habits of young children, whereas the role of income is not clear. There is a need for further high-quality research, preferably longitudinal studies, to inform health promotion initiatives and preventive strategies to facilitate healthy growth and development in young children.

Full textAbstract:
Background: Dietary habits were investigated as environmental risk factors for Attention-Deficit/Hyperactivity Disorder (ADHD). However, no previous studies explored the effects of dietary factors on modifying the role of genetic factors on ADHD. Methods: Based on a Swedish population-based twin study with 1518 twin pairs aged 20–47 years, we tested whether the importance of genetic and environmental effects on ADHD varied as a function of dietary habits. Self-reported dietary habits and ADHD symptoms were collected. Twin methods were used to test the degree to which high-sugar and unhealthy food intake moderated the genetic and environmental influences on ADHD symptoms. Results: In middle-aged adults, genetic influences on inattention symptoms were statistically significantly higher among individuals with higher levels of high-sugar (45%, 95%CI: 25–54%) and unhealthy food intake (51%, 95%CI: 31–60%), compared with those with lower levels of consumption of high-sugar (36%, 95%CI: 25–47%) and unhealthy foods (30%, 95%CI: 20–41%). Similar patterns were also found for the associations between hyperactivity/impulsivity and high-sugar/unhealthy food intake, even though the moderation effects were not statistically significant. Conclusion The present study suggests that genetic factors play a more prominent role in individual differences of ADHD symptoms in the presence of the high consumption of sugar and unhealthy foods. Future longitudinal studies with multiple assessments of ADHD and dietary habits are needed to replicate our findings.

"Gastrointestinal Hormones in Healthy Adults: Reliability of Repeated Assessments and Interrelations with Eating Habits and Physical Activity." Nutrients 13, no. 11 (October 26, 2021): 3809. http://dx.doi.org/10.3390/nu13113809.
Full textAbstract:
Background: Gastrointestinal hormones (GIHs) are crucial for the regulation of a variety of physiological functions and have been linked to hunger, satiety, and appetite control. Thus, they might constitute meaningful biomarkers in longitudinal and interventional studies on eating behavior and body weight control. However, little is known about the physiological levels of GIHs, their intra-individual stability over time, and their interaction with other metabolic and lifestyle-related parameters. Therefore, the aim of this pilot study is to investigate the intra-individual stability of GIHs in normal-weight adults over time. Methods: Plasma concentrations of ghrelin, leptin, GLP-1 (glucagon-like-peptide), and PP (pancreatic polypeptide) were assessed by enzyme-linked immunosorbent assay (ELISA) in 17 normal-weight, healthy adults in a longitudinal design at baseline and at follow-up six months later. The reliability of the measurements was estimated using intra-class correlation (ICC). In a second step, we considered the stability of GIH levels after controlling for changes in blood glucose and hemoglobin A1 (HbA1c) as well as self-reported physical activity and dietary habits. Results: We found excellent reliability for ghrelin, good reliability for GLP1 and PP, and moderate reliability for leptin. After considering glucose, HbA1c, physical activity, and dietary habits as co-variates, the reliability of ghrelin, GLP1, and PP did not change significantly; the reliability of leptin changed to poor reliability. Conclusions: The GIHs ghrelin, GLP1, and PP demonstrated good to excellent test–retest reliability in healthy individuals, a finding that was not modified after adjusting for glucose control, physical activity, or dietary habits. Leptin showed only moderate to poor reliability, which might be linked to weight fluctuations, albeit small, between baseline and follow-up assessment in our study sample. Together, these findings support that ghrelin, GLP1, and PP might be further examined as biomarkers in studies on weight control, with GLP1 and PP serving as anorexic markers and ghrelin as an orexigenic marker. Additional reliability studies in obese individuals are necessary to verify or refute our findings for this cohort.

Full textAbstract:
Aims and background The objectives of the present study were to validate the social stratification variables adopted by the European Prospective Investigation into Cancer and Nutrition (EPIC) by comparing them with data from another independent source and to evaluate the geographic and social distribution of eating habits in the Italian EPIC population. Methods The validation of the socioeconomic data collected by the EPIC study was performed with the Turin Longitudinal Study as gold standard and using Cohen's kappa statistics to evaluate the concordance between the studies. We then analyzed food groups based on the consumption of meat and fats, carbohydrates, sweets and alcohol, and on an index of the Mediterranean diet. The standardized scores for each food group were subdivided into quartiles, which were used to compare persons in the extreme quartiles. Analysis of the differences in eating habits by center and by educational level was conducted separately for men and women, calculating the prevalence rate ratios and controlling for age, area of birth and body mass index. Results Concordance between the two data sources was high for educational level and low for the social-class index based on occupation. Most of the eating habits considered to be potentially harmful (high consumption of meat or fats and alcohol and low consumption of olive oil and fish) were more frequent in Northern than in Southern Italy. These habits were inversely correlated with educational level, especially in the South. Conclusions A significant improvement in health could be obtained in the Italian population if culturally and socioeconomically disadvantaged individuals were to abandon their diet rich in meat and fats, as done by more advantaged persons. In the absence of preventive interventions specifically addressed to disadvantaged groups, it is likely that social inequalities in mortality and morbidity will increase.

"Dietary Habits Modify the Association of Physical Exercise with Cognitive Impairment in Community-Dwelling Older Adults." Journal of Clinical Medicine 11, no. 17 (August 30, 2022): 5122. http://dx.doi.org/10.3390/jcm11175122.
Full textAbstract:
Background: Previous studies have confirmed that both healthy diets and physical exercise have preventive effects with respect to cognitive decline with aging. The aim of this study was to investigate whether the associations of physical exercise with cognitive impairment differ in community-dwelling older adults with different dietary habits. Methods: In the 2008/2009 wave of the Chinese Longitudinal Healthy Longevity Survey, 14,966 community-dwelling older adults (≥65 years) were included for analyses. Dietary habits (including daily intake of fruits, vegetables, tea, meat, fish, eggs, food made from beans, salt-preserved vegetables, sugar, garlic, milk products, nut products, mushroom or algae, vitamins and medicinal plants) and physical exercise were assessed. Cognitive impairment was evaluated using the Chinese version of the MMSE in the 2008/2009 and 2011/2012 waves. The effect modifications of physical exercise on cognitive impairment by dietary habits were estimated using logistic regression models. Results: Older adults who practiced physical exercise exhibited a trend of decreased probability of cognitive impairment at baseline and follow-up (OR = 0.92, 95% CI = 0.80–1.06, p = 0.273; OR = 0.83, 95% CI = 0.65–1.05, p = 0.123, respectively) compared with those who did not practice physical exercise. When stratified by dietary habits, physical exercise had a protective effect with respect to prevalent cognitive impairment in older adults who ate fruits (OR = 0.74, 95% CI = 0.58–0.94, p = 0.016), ate food made from beans (OR = 0.76, 95% CI = 0.62–0.93, p = 0.007), did not eat sugar (OR = 0.81, 95% CI = 0.68–0.98, p = 0.028) and ate milk products (OR = 0.75, 95% CI = 0.57–0.97, p = 0.030); in the longitudinal analyses, physical exercise had a protective effect with respect to incident cognitive impairment in older adults who ate fruits (OR = 0.63, 95% CI = 0.41–0.98, p = 0.040) and milk products (OR = 0.57, 95% CI = 0.35–0.94, p = 0.027). Fruits, food made from beans and milk products modified the associations of physical exercise with prevalent cognitive impairment (p values for interaction = 0.008, 0.005 and 0.082, respectively). Conclusions: The associations of physical exercise with cognitive impairment could be modified by certain dietary habits. Physical exercise was not found to be significantly protective with respect to cognitive impairment in older adults unless they had specific dietary habits. Thus, dietary habits should be emphasized when investigating the beneficial effects of physical exercise on cognitive function in community-dwelling older adults.

"Parental Misperceptions of Their Offspring’s Weight and Their Strategies for Child’s Eating Behavior: A Narrative Review of the Recent Evidence." Children 9, no. 10 (October 16, 2022): 1565. http://dx.doi.org/10.3390/children9101565.
Full textAbstract:
The aim of the present review was to explore the effect of parental misperceptions of their offspring’s weight status during childhood and early adolescence on weight control strategies and children’s eating behavior. Literature searching was limited to the PubMed database and to the English language from January 2000 to August 2022. Eligible studies had clearly associated parental misperception of offspring’s weight with child eating habits or weight management and eating strategies in childhood to early adolescence. Sixteen studies (14 cross-sectional, 1 longitudinal and 1 with cross-sectional and longitudinal analyses) were included in the analysis. Weight loss attempts and child’s eating behavior were the main outcomes. Sixteen studies found significant associations. Parental misperceptions of their offspring’s weight status do influence their child’s weight and eating behavior, especially in overweight children. Parents tend to follow potentially harmful methods when they overestimate their children’s weight (food restriction) and when they underestimate their children’s weight (pressure to eat). However, additional longitudinal studies are needed to better understand the impact of parental weight status perception on health behaviors and children’s weight gain over time. The potential need for preventive intervention studies is warranted.

Full textAbstract:
Breakfast skipping increases with age, and an association with a high risk of being overweight (OW) and of obesity (OB), cardiometabolic risk, and unhealthy diet regimen has been demonstrated in observational studies with children and adults. Short-term intervention trials in adults reported conflicting results. The purpose of this systematic review was to summarize the association of breakfast skipping with body weight, metabolic features, and nutrition quality in the groups of young people that underwent randomized controlled (RCT) or intervention longitudinal trials lasting more than two months. We searched relevant databases (2000–2021) and identified 584 articles, of which 16 were suitable for inclusion. Overall, 50,066 children and adolescents were included. No studies analyzed cardiometabolic features. Interventions were efficacious in reducing breakfast skipping prevalence when multi-level approaches were used. Two longitudinal studies reported a high prevalence of OW/OB in breakfast skippers, whereas RCTs had negligible effects. Ten studies reported a lower-quality dietary intake in breakfast skippers. This review provides insight into the fact that breakfast skipping is a modifiable marker of the risk of OW/OB and unhealthy nutritional habits in children and adolescents. Further long-term multi-level intervention studies are needed to investigate the relationship between breakfast, nutrition quality, chronotypes, and cardiometabolic risk in youths.

Consumers purchase environmentally friendly products ‘’Organic food’’. This study is applied in Pakistan a country in which there is concern about safety and quality. The ‘’SEM’’ model is used to support our study. Three independent variables while one dependent variable is taken in that scenario. Data were obtained from 300 respondents, 278 backed us their response. We conclude from the above-mentioned model that the packing factor has much important than that of other variables. This sort of research can conduct in developed countries such as the US, CHINA, CANADA and other geographic areas. Also, green marketing factors can be replaced for future studies. Different independent variables contribute to future research like organic food labeling, lack of knowledge, and availability. We can also use different aspects such as environmental concern, health concern, and food safety concern using them as independent variables we can further use them in new research as a research gap. this research can also be done as longitudinal research.

Introduction: The nutritional transition in Brazil has also reached the infant population. In this context, studies have demonstrated high prevalence of overweight and obesity in school-aged children.
Objective: analyze the nutritional and anthropometric status of children in a public school between the years of 2013 and 2015.
Methods: for which a longitudinal study was developed using a 2013 baseline study. The final sample consisted of 73 students with initial age between 3 and 9 years. Socioeconomic, anthropometric and school feeding practices were collected using questionnaires according to the school age. The nutritional status was determined by the collection of measures of weight and height, later these were used for expression z Weight / Age and Height / Age scores. SPSS was used for statistical analysis.
Results: The results showed that a significant percentage of schoolchildren remained overweight and obese from the Weight / Age index (21.8%) and at low weight risk by the Height / Age and Weight / Age (4.1% and 3%, 6%). These students presented a growth and weight gain within the norms of normality and the majority presented adequate weight for the age, nevertheless there was an expressive portion of schoolchildren who are underweight and overweight / obese.
Conclusions: The nutritional status of children is related to several factors that should be addressed through actions to develop food and nutrition surveillance and food and nutrition education with students to promote healthy eating habits.

Full textAbstract:
Rural Australians experience a higher burden of diet-related chronic disease than their metropolitan counterparts. Dietary intake data is needed to understand priorities for nutrition initiatives that reduce disparities in the health of rural Australians. A systematic literature review aimed to synthesize the evidence on dietary intakes in adult populations residing in rural and remote Australia, to identify areas for intervention, and make recommendations for future research. A comprehensive search of five electronic databases was conducted and 22 articles were identified for inclusion. Half of the included studies (50%) collected dietary data using non-validated questionnaires and nearly half (41%) did not benchmark dietary intakes against public health guidelines. Most studies (95%) showed that rural populations have suboptimal dietary intakes. Despite the high level of preventable diet-related disease in rural and remote Australia, this review identified that there is insufficient high-quality dietary data available and a lack of consistency between dietary outcomes collected in research to inform priority areas for intervention. Further cross-sectional or longitudinal data should be collected across all remoteness areas, using robust, validated dietary assessment tools to adequately inform nutrition priorities and policies that reduce rural health disparities.

Full textAbstract:
Two species of large black whip snakes (Demansia vestigiata and D. papuensis) are morphologically and ecologically similar and have broadly overlapping distributions. A long history of taxonomic difficulties has meant that most previous taxonomic and ecological studies comprise composite samples of both taxa. Here, we provide ecological data (body sizes, food habits, reproduction and inferred growth rates) collected from captured and road-killed specimens from a tropical population of D. vestigiata at Townsville, north-eastern Queensland, Australia. Males attain larger body sizes and have longer tails than females. All food items were ectotherms (lizards and frogs). Female reproductive cycles were strongly seasonal. Clutch size is significantly positively related to maternal body size. Egg dimensions, clutch mass and neonatal size are reported. Inferred growth rates indicate that sexual maturation is attained at ~21 months for females.

Full textAbstract:
Brown tree snakes (Boiga irregularis) are medium to large colubrid snakes that are relatively common within the eastern and northern parts of tropical Australia. An invasive population on Guam in the western Pacific has resulted in B. irregularis being one of the most studied snakes on earth. However, no field studies have ever been conducted on Australian populations. During a seven-year period we collected data on 265 field-caught specimens in north Queensland. These snakes were from three populations and provided data on body sizes, activity times, food habits and reproduction. B. irregularis were found to attain larger body sizes in the Wet Tropics populations than in the Townsville and Magnetic Island populations. More snakes were encountered during the wet and warm season than during the dry and cool season. Sexual size dimorphism was not detected in any population. The diet included a wide range of vertebrates. Reproductive data were scant from the populations examined.

Full textAbstract:
Heterotrophic organic-carbon cycling is a major source of energy to aquatic food webs, yet there are few studies into patterns of heterotrophic productivity in large lowland rivers. The Lachlan River experienced a period of extreme flow variability from September 2010 to February 2011; for example, daily discharge (ML day–1) at one site reached >22 times its 10-year average. Heterotrophic cycling of dissolved organic carbon (DOC) and particulate organic carbon (POC) were assessed over this period at six sites on the Lachlan River. Concentrations of total organic carbon (TOC) ranged from 7 to 30 mg L–1, of which the majority was in dissolved form. Concentration of DOC was positively correlated with daily discharge. Biochemical oxygen demand of TOC over 5 days (BOD5) showed significant variability, ranging from 0.6 to 6.6 mg O2 L–1. BOD5 did not appear related to discharge, but instead to a range of other factors, including regulation via weirs, lateral and longitudinal factors. Partitioning of DOC and POC showed that POC had an influence on BOD5 comparable to DOC. This is relevant to environmental-flow management in the Lachlan River, the Murray–Darling Basin and rivers generally, by showing that flow variability influences a fundamental ecosystem characteristic, namely organic carbon.

Full textAbstract:
We examined the evidence for intermittent fasting (IF) as a preventative tool to influence β-amyloid in animal models of Alzheimer’s disease (AD). A Scopus, Ovid, PubMed, and Web of Science (WoS), search yielded 29 results using the keywords “amyloid beta”, “intermittent fasting”, “intermittent caloric restriction”, “alternate day fasting”, “modified alternate-day fasting”, “time-restricted feeding”, “Ramadan fast”, “intermittent calori* restriction”, “intermittent restrictive diet”, and “Alzheimer*”. Five research articles addressed directly the effects of intermittent fasting on β-amyloid levels in animal models of AD: alternate day fasting (ADF) and time-restricted feeding (TRF) methods were incorporated in these studies. The study designs were found to be heterogeneous. Variations in the levels of β-amyloid peptides or plaque in either the hippocampus, cortical areas, or both in animals following dietary intervention were observed as compared to the ad libitum group. Non-significant changes were observed in three studies, while two studies interestingly demonstrated amelioration and reduction in β-amyloid levels. Given the conflicting results obtained from this study, significant care has to be taken into consideration before the protocol can be applied as a preventative approach to treat Alzheimer’s disease. Longitudinal research is warranted to fully grasp how dietary habits can help alleviate the disease either through upstream or downstream of AD pathology.

Full textAbstract:
Two 3-month longitudinal studies examined weight loss following a 1-month behavioral intervention (FIT-DSD) focusing on increasing participants’ behavioral flexibility and breaking daily habits. The goal was to break the distal habits hypothesized as playing a role in unhealthy dietary and activity behaviors. The FIT-DSD intervention required participants to do something different each day and to engage in novel weekly activities to expand their behavioral repertoire. These activities were not food- or exercise-related. In Study 1, the FIT-DSD program was compared with a control condition where participants engaged in daily tasks not expected to influence behavioral flexibility. Study 2 used an active or quasicontrol group in which half the participants were also on food diets. Measures in both studies were taken pre-, post-, and post-postintervention. In Study 1, FIT-DSD participants showed greater weight loss that continued post-postintervention. In Study 2, all participants on the FIT-DSD program lost weight, weight loss continued post-postintervention, and participants who were also dieting lost no additional weight. A dose relationship was observed between increases in behavioral flexibility scores and weight loss, and this relationship was mediated by calorie intake. Corresponding reductions in BMI were also present. Increasing behavioral flexibility may be an effective approach for tackling obesity and also provides affective and potential life-skill benefits.

Full textAbstract:
Parental self-efficacy (PSE), a measure of the subjective competence in the parental role, has been linked with child well-being and health. Research on the influence of PSE on child eating habits is scarce, and the few studies have concentrated on certain food groups, such as vegetables or fruits, and have mostly included only maternal PSE. Thus, the aim of this study was to explore the associations between PSE (separately for mothers and fathers and as a total family-level score) and child diet quality in a cross-sectional and longitudinal study setting. PSE was measured at child ages of 1.5 and 5 years, and diet quality was measured at ages 2 and 5. Participants are from the Steps to Healthy Development (STEPS) Study (n = 270−883). We found that maternal PSE and family level PSE score were associated with child diet quality. Paternal PSE was not, but the dimension Routines was associated with child diet quality. PSE was similarly associated with child diet quality at both age points. Our results suggest that PSE is an important construct in the development of healthy dietary habits in children, and supporting parenting programs aimed at higher PSE could promote healthy diet quality in children.

Full textAbstract:
Slaty grey snakes (Stegonotus cucullatus) are medium to large members of the Colubridae that are common throughout the eastern and northern tropics of Australia. Although intensive field studies have been conducted on populations in the Northern Territory for over 10 years, no ecological data have been presented on free-ranging specimens of populations inhabiting tropical north Queensland. During a 10-year period we collected opportunistic data on 120 free-ranging specimens from the seasonally Wet Tropics in north Queensland. These snakes provided data on body sizes, activity times, food habits and reproduction. Male S. cucullatus were larger than females and had larger heads. More snakes were found during the warmer, humid parts of the year (wet season). S. cucullatus ate a wide range of vertebrate prey, including reptile eggs that were obtained seasonally. Females produced one clutch per year, and no relationship was found between maternal snout–vent length and clutch size.

Introduction: With the increase of childhood obesity, early intervention in nutrition education becomes necessary. Therefore, during the school period, the school becomes the best place for implementation of a nutritional education program.
Objective: The current study was carried out in a public and in a private school, with the objective of evaluating and comparing the results of the "Nutriamigos®" Program on food and nutrition knowledge of children with different socioeconomic levels, sex, age and Body Mass Index (BMI).
Method: Comparative longitudinal study, before and after educational intervention. To evaluate the intervention, a public (school 1) and a private school (school 2) were selected. This was a random, convenience sample comparing students from different social and economic levels, consisting of 242 (school 1) and 99 children (school 2), respectively, totaling 341 children, from 6 to 10 years of age. The Body Mass Index was used to measure nutritional status. Knowledge about food and nutrition was evaluated through a questionnaire, applied before and after intervention. The nutritional intervention consisted of 12 classes of 50 minutes each.
Results: The improvement in knowledge on food and nutrition between the pre and post intervention stages was statistically significant.
Conclusion: The "Nutriamigos®" Program reached its goal, demonstrating that it is effective in public and private schools and should not be differentiated for boys or girls, or for children with normal or excessive weight.

: High visceral fat area (VFA) is a stronger predictor of cardiovascular disease and overall mortality than body mass index or waist circumference. VFA may be decreased by proper dietary habits. Although previous epidemiologic studies demonstrated an association between nutritional components or foodstuffs and VFA, only the associations of a few nutrients, such as dietary fiber and calcium, are reported. We performed a comprehensive 2-year longitudinal study in more than 624 healthy people and analyzed 33 micronutrients to investigate nutrients that contribute to changes in visceral fat. Our analyses revealed that “macronutrients” and “micronutrients” were “mutual confounders”. Therefore, when evaluating the association between VFA and micronutrients, associations were adjusted by macronutrients. The ingestion of 7 nutrients: soluble dietary fiber, manganese, potassium, magnesium, vitamin K, folic acid, and pantothenic acid, which are abundant components in vegetable diets, was significantly inversely correlated with a change in VFA. Additionally, a change in the ingestion of one nutrient, monounsaturated fat, was significantly positively correlated with a change in VFA. These associations were independent of body mass index and waist circumference. Thus, a predominantly vegetable diet may decrease VFA. In addition, adjusting the intake of macronutrients might help to clarify the association of micronutrients with VFA.

Residential areas may shape health, yet few studies are longitudinal or concurrently test relationships between multiple residential features and health. This longitudinal study concurrently assessed the contributions of multiple environmental features to 10-year change in clinically measured body mass index (BMI) and waist circumference (WC). Longitudinal data for adults (18+ years of age, n = 2253) from the north-west of Adelaide, Australia were linked to built environment measures representing the physical activity and food environment (expressed for residence-based 1600 m road-network buffers) and area education. Associations were concurrently estimated using latent growth models. In models including all environmental exposure measures, area education was associated with change in BMI and WC (protective effects). Dwelling density was associated with worsening BMI and WC but also highly correlated with area education and moderately correlated with count of fast food outlets. Public open space (POS) area was associated with worsening WC. Intersection density, land use mix, greenness, and a retail food environment index were not associated with change in BMI or WC. This study found greater dwelling density and POS area exacerbated increases in BMI and WC. Greater area education was protective against worsening body size. Interventions should consider dwelling density and POS, and target areas with low SES.

Full textAbstract:
Knowledge on the role of diet in tinnitus onset is mostly based on few cross-sectional studies. In 2016–2019 we conducted a hospital-based case-control study in northern Italy on 185 incident idiopathic tinnitus cases and 198 controls, providing data on dietary habits through a 37-item food-frequency questionnaire. Odds ratios (OR) for tinnitus risk were derived through unconditional multiple logistic regression models. Moderate-to-high vs. low intake of caffeine (OR, 0.49; 95% confidence interval (CI), 0.24–0.99) and butter (OR, 0.46; 95% CI, 0.23–0.93), and high vs. low intake of poultry (OR, 0.43; 95% CI, 0.23–0.81), prosciutto (OR, 0.44; 95% CI, 0.23–0.85), and legumes (OR, 0.50; 95% CI, 0.28–0.92) were inversely associated with tinnitus onset. Other food items, including cereals, red meat, fish, vegetables, and fruit did not show any statistically significant relationship. The variety of food consumed decreased the risk of tinnitus (OR for at least 20 vs. less than 16 different food items, 0.47; 95% CI, 0.24–0.90). Our findings highlight the importance of diet in tinnitus onset and confirm a potential inverse association of protein-rich food and caffeine on the incidence of tinnitus. Confirmation of our findings in longitudinal studies is necessary before proving any diet recommendations for tinnitus prevention.

Full textAbstract:
Restricting animal-based products from diet may exert beneficial effects on weight status; however, less is known about such a diet and emotional health. Moreover, personality traits, for example high neuroticism, may contribute to restrictive eating habits and potentially confound diet-health associations. We aim to systematically assess if restrictive dietary intake of animal-based products relates to lower weight and higher depressive symptoms, and if differences in personality traits play a significant role. Cross-sectional data from the baseline LIFE-Adult study were collected from 2011–2014 in Leipzig, Germany (n = 8943). Main outcomes of interest were dietary frequency of animal-derived products in the last year measured using a Food Frequency Questionnaire (FFQ), body-mass-index (BMI) (kg/m2), and the Center of Epidemiological Studies Depression Scale (CES-D). Personality traits were assessed in a subsample of n = 7906 using the Five Factor Inventory (NEO-FFI). Higher restriction of animal-based product intake was associated with a lower BMI, but not with depression scores. Personality, i.e., lower extraversion, was related to lower frequency of animal product intake. Moreover, personality traits were significantly associated with depressive symptoms, i.e., higher neuroticism, lower extraversion, lower agreeableness, lower conscientiousness, and with higher BMI. These findings encourage future longitudinal studies to test the efficacy of restricting animal-based products as a preventive and therapeutic strategy for overweight and obesity.

Full textAbstract:
Purpose Previous research has extensively examined “food deserts,” where access to healthy food is limited. However, little is known of the buying behavior at the individual household level in terms of buying habits and consumption in these areas. The purpose of this paper is to determine to what extent other factors than access can account for the purchase of healthy food products, namely, fruits and vegetables. Design/methodology/approach This paper proposes to partially fill this gap through a qualitative (n=55) and quantitative (n=512) study of those people who are in charge of their household purchases in two food deserts in the city of Montreal. Findings Results show that geographical access to supermarkets is not the main factor fostering the purchase of healthy foods (fruits and vegetables). Indeed, food education (e.g. information, simple recipes, cooking classes), associated with a changing mediation process through product diversification (e.g. availability of local products in bulk) and supply (e.g. farmers) seems to be more significant. Research limitations/implications Future studies could compare the results obtained through this study in different socio-demographic contexts. Longitudinal analyses could also increase the understanding of the social and commercial challenges. Originality/value In contrast to previous studies, the results show that geographical access to supermarkets is not the main factor fostering the purchase of fruits and vegetables. Indeed, food education (e.g. information, simple recipes, cooking classes), associated with a changing mediation process through product diversification (e.g. products in bulk) and supply (e.g. farmers) seem to be more significant.

Full textAbstract:
This synopsis paper aims to identify if a common pattern of learning and social difficulties can be conceptualized across recent longitudinal studies investigating the influence of mild-to-moderate gestational iodine deficiency (GID) on offspring’s optimal cognitive and psycho-social development. The main studies investigated are: The Southampton Women’s Study (SWS)—United Kingdom; the Avon Longitudinal Study of Parents and Children (ALSPAC)—United Kingdom; the Gestational Iodine Cohort Longitudinal Study—Tasmania, Australia, and the Danish National Birth Cohort Case-Control Study—Denmark. In contrast to severe GID where there is a global negative impact on neurodevelopment, mild-to-moderate intrauterine iodine deficiency has subtler, but nonetheless important, permanent cognitive and psycho-social consequences on the offspring. This paper links the results from each study and maintains that mild-to-moderate GID is associated with a disorder that is characterized by speed of neural transmitting difficulties that are typically associated with working memory capacity difficulties and attention and response inhibition. The authors maintain that this disorder is better identified as Gestational Iodine Deficiency Processing Disorder (GIDPD), rather than, what to date has often been identified as ‘suboptimal development’. The Autistic Spectrum Disorder (ASD), Attention Deficit, Hyperactivity Disorder (ADHD), language and literacy disorders (learning disabilities and dyslexia) are the main manifestations associated with GIDPD. GIDPD is identified on IQ measures, but selectively and mainly on verbal reasoning IQ subtests, with individuals with GIDPD still operating within the ‘normal’ full-scale IQ range. Greater consideration needs to be given by public health professionals, policy makers and educators about the important and preventable consequences of GID. Specifically, more emphasis should be placed on adequate iodine intake in women prior to pregnancy, as well as during pregnancy and when lactating. Secondly, researchers and others need to further extend, refine and clarify whether GIDPD, as a nosological (medical classification) entity, is a valid disorder and concept for consideration.

IntroductionObesity is a global pandemic that affects all socioeconomic strata, however, the highest figures have been observed in the most disadvantaged social groups. Evidence from the USA and Canada showed that specific urban settings encourage obesogenic behaviour in the population living and/or working there. We aim to examine the evidence on the association between local food environments and obesity in the UK, Ireland, Australia and New Zealand.MethodsSix databases from 1990 to 2017 will be searched: MEDLINE (Ovid), Embase (Ovid), Scopus, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), Applied Social Sciences Index and Abstracts (ASSIA) and Web of Science. Grey literature will also be sought by searching Opengrey Europe, The Grey Literature Report and relevant government websites. Additional studies will be retrieved from the reference lists of the selected articles. It will include cohort, longitudinal, case study and cross-sectional studies that have assessed the relationship between local food environments and obesity in the UK, Ireland, Australia and New Zealand regardless of sex, age and ethnicity of the population. Two researchers will independently select the studies and extract the data. Data items will incorporate: author names, title, study design, year of study, year exposure data collected, country, city, urban/rural, age range, study exclusions, special characteristics of study populations, aims, working definitions of food environments and food outlets, exposure and methods of data collection, outcomes and key findings. A narrative synthesis and a summary of the results will be produced separately for children and adults, according to the type of food exposure–outcome. All the selected studies will be assessed using The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.Ethics and disseminationThis study will be based on published literature, and therefore ethical approval has not been sought. Our findings will be presented at relevant national and international scientific conferences and published in a peer-reviewed journal.

Full textAbstract:
It is widely believed that young people are not overly concerned about their health or that they take excessive care of their eating habits. However, marketing experts see them as an extremely important and potentially large market, and consider all socially responsible business initiatives as long-term investments that will increase the value of the company. In the healthy food market, marketing practices are among the most important activities of socially responsible business. The purpose of this study is to explore the importance of different socially responsible marketing practices on the healthy food market. The questionnaire was administered to 519 students and the results were analysed using latent class analysis (LCA). Research results confirm the importance of understanding the influence of key demographic variables (gender and household income) on customers’ perceptions of socially responsible marketing. An important limitation of the research is the number and selection of socially responsible marketing practices. There are only a few studies that segment the market based on socially responsible marketing practises. A suggestion for future research is to use longitudinal data with more marketing practices tested.

Aim: The aim of this study was to examine the reported frequency of breakfast intake and selected food and beverages in the investigated group of Swedish children in comparison with recommended intakes. Furthermore, the study analyses these food habits and some demographic and lifestyle factors in relation to overweight and obesity. Methods: This cross-sectional study builds on data collected in 2008 and 2010. Measured anthropometric data and parent questionnaire data were collected. A total of 2620 Swedish children (52.1% boys) aged seven to nine years were included. Results: The majority of parents reported that their children (95.4%) had breakfast every day. The majority of children had fresh fruit (84.7%) and vegetables (83.9%) most days a week. Only 1.6% of the children were reported to have fast food and 6.0% to have sugar containing soft drinks, four days a week or more. The prevalence of overweight including obesity (OW/OB) was 17.8% for boys, 18.6% for girls. The odds of being OW/OB was higher among those not having breakfast every day (odds ratio (OR) 1.9, 95% confidence interval (CI) 1.20–2.96), drinking diet soft drink (OR 2.6, 95% CI 1.52–4.42) and skimmed/semi-skimmed milk (OR 1.8, 95% CI 1.37–2.36) four days a week or more. Parents being overweight and having low education levels were also related to a higher risk of their children being overweight. Conclusions: The parental reports of children’s food habits pointed at favourable eating patterns for most investigated children. Breakfast skipping, diet soft drinks and low-fat milk consumption were more frequent among OW/OB children. Longitudinal studies are needed to determine the causal relationships.

Objective: The 2019 coronavirus disease (COVID-19) is a global public health emergency resulting in lockdowns, associated food habits and lifestyle changes and constraint public health delivery. The aim of this study was to investigate the impact of the COVID-19 induced lockdown in Italy on lifestyle behaviours among physically active population adults. Materials and Methods: A cross-sectional online survey was conducted from April to June 2020 on 175 subjects (48.6% males and 18–66 age range) by a structured questionnaire to collect information on demographic characteristics, anthropometric data, lifestyle factors and dietary habits. Results: It merged that 40% of the sample gained weight (≈1kg) with no significant differences between genders. Alcohol consumption and physical activity practice and duration significantly decreased during lockdown, while physical activity frequency, sedentary activities, sleep times, daily breakfast habits and consumption of sweets significantly increased. A multiple logistic regression model showed that education level, nutritional status, frequency of physical activity, eating between meals, and sweet consumption had a significant effect on weight gain during COVID-19. Conclusions: Lockdown had a bi-directional impact (both positive and negative) on lifestyle changes, because more time was spent at home. These results need to be confirmed with further longitudinal studies among a larger population sample to better understand the lasting effects of this pandemic on lifestyle behaviors and their changes. Key words: Covid-19, lifestyle behaviour, lockdown, pandemic, physical activity.

Both brown (detrital-based) and green (algal-based) food pathways support freshwater food webs, although the importance of either source may vary within species, regions and different phases of the flow regime. The bony bream (Nematalosa erebi Clupeidae: Dorosomatinae) is one of Australia's most widely distributed freshwater fish species and is a key component of freshwater food webs, especially in northern Australia. We sought to better define the feeding habits of this species, previously classified as a detritivore, algivore or zooplanktivore (or combinations thereof), by undertaking meta-analyses of published accounts based on stomach content analysis and 13C and 15N stable isotope analysis. Stomach content analysis clearly indicated that detritus was the dominant food item, although benthic algae could be an important dietary component in some habitats (inland river flood plains) and during the wet season. Zooplankton were important for small fish (i.e. juveniles 13C enriched, indicating the latter source was not the dominant contributor to the biomass of this species. However, using site-specific data and a regression approach, a significant relationship was revealed between algal carbon and that of large fish, suggesting that carbon derived from benthic algae contributed ~20% of the carbon of adult bony bream. Zooplankton contributed a similar amount. Zooplankton provided the majority of carbon for small fish. We contend that detritus derived from terrestrial vegetation is the likely remaining carbon source for large bony bream, and this interpretation was supported by the outcomes of multiple regression analyses. Although previous studies of aquatic food webs in northern Australia have emphasised the importance of high-quality algal basal resources, this study indicates that terrestrial sources may be important for some species and demonstrates the need to better consider the circumstances that cause biota to switch between different food sources.

The present work aimed to describe and compare both gross and microscopic structure of the oesophagus of Nile tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus). For this purpose, 60 specimens of oesophagus of Nile tilapia (omnivorous fish) and African catfish (carnivorous fish) were collected and processed. Anatomically, the oesophagus of both species appeared as a short tube with longitudinal mucosal folds. Using scanning electron microscope, the epithelial surface of the esophagus showed primary and secondary mucosal folds in both species while tertiary folds were observed in that of tilapia only. Histologically, the oesophagus consisted of four distinct layers: mucosa, submucosa, muscularis, and serosa. The oesophageal mucosa consisted of stratified epithelium with few mucous secreting cells in catfish and many mucous secreting cells in tilapia. Two types of mucous secreting cells reacted positively with both periodic acid shiff (PAS) and alcian blue (AB); rounded and elongated cells that were recognized in the esophageal epithelium of tilapia and only elongated oval cells were observed in that of catfish. In conclusion, the obtained histomorphological differences in esophagus of both fish species may be attributed to their different feeding habits and type of food.

Background: Mildest carbohydrate intolerance during pregnancy may increase the risk of maternal and foetal complications. Studies suggest interesting relationships between elevated 1st trimester SUA and development of GDM, but they have not been consistent and as per our literature search we did find only one or two such studies carried out on South-Indian women in whom, the food habits, genetics, environmental factors differ from rest of the world.Methods: 124 pregnant women were studied with an aim to prospectively evaluate relation between 1st trimester SUA levels with development of GDM. Continuous data were analyzed for average/mean, median and standard deviation; and categorical variables using chi-square, independent t-test, Pearson’s correlation coefficient and ANOVA.Results: 36% of the study sample had risk factors for GDM with an incidence of 22.6%. Pearson correlation with 1st trimester SUA concentration of 3.2 mg/dl as a cut-off point for predicting GDM risk was found to be statistically significant. At cut-off levels of 3.98 mg/dl, risk of women developing GDM requiring insulin therapy in addition to diet was statistically significant.Conclusions: Along with other risk factors, elevated 1st trimester SUA levels is an independent risk factor for development of GDM. If diagnosed early and properly monitored, GDM usually doesn’t affect pregnancy outcome in our population.

AbstractObjectiveDespite the usefulness of quantitative research, qualitative research methodologies are equally needed to allow researchers to better understand the important social and environmental factors affecting food choice and eating habits. The present paper contributes insights from narrative inquiry, a well-established qualitative methodology, to a food-related doctoral research study. The connections between food shoppers and the producer, family, friends and others in the food system, between eaters and the earth, and how these connections affect people’s meaning-making of food and pathways to food citizenship, were explored in the research.DesignThe research used narrative inquiry methodology and focus groups for data collection.SettingFive different food-ways in the Canberra region of Australia were selected for the present research; that is, community gardens, community-supported agriculture, farmers’ markets, fresh food markets and supermarkets.SubjectsFifty-two people voluntarily attended eight focus groups with four to nine participants in each.ResultsFrom a practical perspective, the present paper offers a guide to the way in which narrative inquiry has been applied to one research project. The paper describes the application of narrative inquiry methodology, revealing the important place of narratives in generating new knowledge. The paper further outlines how phased narrative analysis can lead to a defensible and rigorous interpretive framework grounded in the data generated from people’s stories and meaning-making.ConclusionsWe argue that individual, social and system change will not be possible without further rigorous qualitative studies to inform and complement the empirical basis of public health nutrition practice.

AbstractOut-of-home foods (takeaway, take-out and fast foods) have become increasingly popular in recent decades and are thought to be a key driver in increasing levels of overweight and obesity due to their unfavourable nutritional content. Individual food choices and eating behaviours are influenced by many interrelated factors which affect the results of nutrition-related public health interventions. While the majority of research based on out-of-home foods comes from Australia, the UK and USA, the same issues (poor dietary habits and increased prevalence of non-communicable disease) are of equal concern for urban centres in developing economies undergoing ‘nutrition transition’ at a global scale. The present narrative review documents key facets, which may influence out-of-home food consumption, drawn from biological, societal, environmental, demographic and psychological spheres. Literature searches were performed and references from relevant papers were used to find supplementary studies. Findings suggest that the strongest determinants of out-of-home food availability are density of food outlets and deprivation within the built environment; however, the association between socio-economic status and out-of-home food consumption has been challenged. In addition, the biological and psychological drives combined with a culture where overweight and obesity are becoming the norm makes it ‘fashionable’ to consume out-of-home food. Other factors, including age group, ethnicity and gender demonstrate contrasting effects and a lack of consensus. It is concluded that further consideration of the determinants of out-of-home food consumption within specific populations is crucial to inform the development of targeted interventions to reduce the impact of out-of-home foods on public health.

Sarcopenia is the loss of skeletal muscle mass, and is most common in older people. The present multi-center cross-sectional study aimed to determine the prevalence of sarcopenia and possible risk factors among Arab elderly females. A total of 131 ambulatory Saudi elderly females aged 60–85 years (mean age 65.9 ± 5.5 years) were recruited to participate. A general questionnaire with questions related to sociodemographic factors, medical history, diet, physical activity, and lifestyle was administered. Anthropometrics and muscle assessments were done. Fasting blood glucose and lipids were measured routinely. Circulating 25(OH)D and irisin levels were measured using commercially available assays. Sarcopenia was assessed using the criteria of the Asian Working Group for Sarcopenia (AWGS). Over-all prevalence of sarcopenia was 19.8% (26 out of 131 participants). Novel measures such as abdominal volume index (AVI), dietary fiber, and irisin were found to be significantly lower in the sarcopenia group than those without sarcopenia, independent of age. No associations were found with physical activity or dietary and lifestyle habits. In conclusion, sarcopenia is relatively common among Arab elderly females. Longitudinal studies are needed to determine whether lifestyle modifications can decrease the incidence of sarcopenia in this population. Irisin maybe a promising biomarker for sarcopenia but needs to be confirmed using larger sample sizes.

Nutritional compounds might modulate depression associated biomarkers and parallel the development of depression, obesity and diabetes. In this context, recent studies revealed new mediators of both energy homeostasis and mood changes (i.e. IGF-1, NPY, BDNF, ghrelin, leptin, CCK, GLP-1, AGE, glucose metabolism and microbiota) acting in gut brain circuits. In this context several healthy foods such as olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy and unprocessed meat have been inversely associated with depression risk and even have been postulated to improve depressive symptoms. In contrast, unhealthy western dietary patterns including the consumption of sweetened beverage, refined food, fried food, processed meat, refined grain, and high fat diary, biscuits, snacking and pastries have been shown to be associated with an increased risk of depression in longitudinal studies. However, it is always difficult to conclude a real prospective causal relationship from these mostly retrospective studies as depressed individuals might also change their eating habits secondarily to their depression. Additionally specific selected nutritional compounds, e.g. calcium, chromium, folate, PUFAs, vitamin D, B12, zinc, magnesium and D-serine have been postulated to be used as ad-on strategies in antidepressant treatment. In this context, dietary and lifestyle interventions may be a desirable, effective, pragmatical and non-stigmatizing prevention and treatment strategy for depression. At last, several medications (pioglitazone, metformin, exenatide, atorvastatin, gram-negative antibiotics), which have traditionally been used to treat metabolic disorders showed a certain potential to treat depression in first randomized controlled clinical trials.

Tailored dietary counseling could be specifically efficient during pregnancy, a period accompanied by a rise in nutrition awareness, but little is known about the expectations of pregnant women in this regard. We studied these expectations regarding tailored dietary advice in French women during their pregnancy, as well as their motivations and the perceived barriers and enablers. In French pregnant women, we evaluated the perceptions of tailored dietary advice provided by stepwise dietary counseling based on three types of dietary changes, consisting of: (1) a modification of the amounts consumed, (2) substitutions within the food subgroups, and (3) substitutions between food subgroups. A sequential explanatory mixed-method approach was designed. Using qualitative data from a focus group study (n = 40), we intended to explore in depth the women’s expectations regarding dietary advice and adherence to a tailored approach. These were combined with quantitative and qualitative data from a 6-week online longitudinal study (n = 115), using questionnaires designed to assess the modifications of dietary habits during pregnancy and to evaluate each type of dietary change. Both studies confirmed that most women in our samples did indeed intend to institute changes regarding healthier dietary practices during pregnancy. The principal motivation behind changes to their habits was to ensure the health and well-being of both their babies and themselves. The proposal of dietary advice that is tailored to both the current diet and the specific needs of pregnant women, but that is also positive and credible, was perceived as enabling implementing healthier dietary practices during pregnancy. Regarding the implementation of the dietary changes proposed, the enablers and barriers identified differed between modifications of the amounts consumed and substitutions. The women displayed interest in all types of dietary changes. This gave relevance to combining different types of changes in order to propose dietary counseling during pregnancy. Tailored dietary counseling was identified by French pregnant women in our samples as enabling them to adopt a healthier diet. However, perceived barriers might limit the implementation of dietary changes, especially when they involved marked modifications to their usual diet.

Full textAbstract:
Although excessive alcohol consumption is by far the most frequent cause of recurrent acute pancreatitis (AP) cases, specific therapy is still not well established to prevent recurrence. Generally, psychological therapy (e.g., brief intervention (BI)) is the cornerstone of cessation programs; however, it is not yet widely used in everyday practice. We conducted a post-hoc analysis of a prospectively collected database. Patients suffering from alcohol-induced AP between 2016 and 2021 received 30 min BI by a physician. Patient-reported alcohol consumption, serum gamma-glutamyl-transferase (GGT) level, and mean corpuscular volume (MCV) of red blood cells were collected on admission and at the 1-month follow-up visit to monitor patients’ drinking habits. Ninety-nine patients with alcohol-induced AP were enrolled in the study (mean age: 50 ± 11, 89% male). A significant decrease was detected both in mean GGT value (294 ± 251 U/L vs. 103 ± 113 U/L, p < 0.001) and in MCV level (93.7 ± 5.3 U/L vs. 92.1 ± 5.1 U/L, p < 0.001) in patients with elevated on-admission GGT levels. Notably, 79% of the patients (78/99) reported alcohol abstinence at the 1-month control visit. Brief intervention is an effective tool to reduce alcohol consumption and to prevent recurrent AP. Longitudinal randomized clinical studies are needed to identify the adequate structure and frequency of BIs in alcohol-induced AP.

Full textAbstract:
Digital media (DM) influences children’s food choice. We aim to investigate associations between DM use and taste preferences (TP) for sweet, fatty, bitter, and salty in European children and adolescents. Individuals aged 6–17 years (N = 7094) providing cross-sectional data for DM use: television (TV), computer/game console (PC), smartphone and internet, were included. Children (6 to <12 years) and adolescents (≥12 years) completed a Food and Beverage Preference Questionnaire; scores were calculated for sweet, fatty, salty and bitter preference and categorized (high vs. low). Logistic regression was used to calculate odds ratios as association measures between DM exposure and TP. On average, individuals used media for 2.4 h/day (SD = 1.7). Increasing exposures to DM were associated positively with sweet, fatty and salty TP, while inversely with bitter preference. In female adolescents, DM exposure for >2 h/day was associated with sweet (OR = 1.27, 95% CI = 1.02–1.57) and fatty preference (OR = 1.37; 95% CI = 1.10–1.70). Internet exposure was inversely associated with bitter preference, notably in male adolescents (OR = 0.65, 95% CI = 0.50–0.84), but positively associated with salty preference (OR = 1.29, 95% CI = 1.02–1.64). DM exposure was associated with sweet, fatty, salty and bitter TP in children and adolescents, serving as the basis for future longitudinal studies to shed light on the underlying mechanism by which DM exposure may determine eating habits.

Abstract Studies have demonstrated that healthy dietary patterns are related to diminished stress. However, the potential moderation role of acculturation on dietary patterns and stress is unclear among the those whose eating habits are impacted by immigration. The aim of this study is to explore the moderation role of acculturation on dietary patterns and stress among Chinese elder immigrants in the United States. Data were conducted from the PINE Study with 3053 Chinese adults aged over 60 years in the Great Chicago area. Dietary patterns were measured via a 48-items Food-frequency questionnaire with frequency and size weighted. Items were identified into different food groups based on Dietary Guidelines. Acculturation was assessed by a 12-item short-scale among the population. Stress was measured via a 10-item Perceived Stress Scale with cutoff 14 indicating either low or high stress. Multiple logistic regression was used to examine the moderation effects on the associations with demographic characteristics, medical comorbidities, and BMI adjusted. After controlling covariates, one unit increasing in fruit consumption (OR: 0.61 (95%CI: 0.52 -0.72)) or coffee (OR: 0.49 (95%CI: 0.36 - 0.67)) was associated with lower odds of stress. However, after adding acculturation as an interaction term, the negative relationship between fruit or coffee consumption with stress was moderated by a higher level of acculturation (fruit: OR: 1.05 (95%CI: 1.02 - 1.08), coffee: OR: 1.05 (95%CI: 1.01 - 1.09) respectively). The associations between dietary patterns and stress may differentiate based on acculturation level among the elder immigrants. Further longitudinal studies should investigate potential causality.

Purpose Colorectal cancer survivors are at risk for poor health outcomes because of unhealthy lifestyles, but few studies have developed translatable health behavior change interventions. This study aimed to determine the effects of a telephone-delivered multiple health behavior change intervention (CanChange) on health and behavioral outcomes among colorectal cancer survivors. Methods In this two-group randomized controlled trial, 410 colorectal cancer survivors were randomly assigned to the health coaching intervention (11 theory-based telephone-delivered health coaching sessions delivered over 6 months focusing on physical activity, weight management, dietary habits, alcohol, and smoking) or usual care. Assessment of primary (ie, physical activity [Godin Leisure Time Index], health-related quality of life [HRQoL; Short Form–36], and cancer-related fatigue [Functional Assessment of Chronic Illness Therapy Fatigue Scale]) and secondary outcomes (ie, body mass index [kg/m2], diet and alcohol intake [Food Frequency Questionnaire], and smoking) were conducted at baseline and 6 and 12 months. Results At 12 months, significant intervention effects were observed for moderate physical activity (28.5 minutes; P = .003), body mass index (−0.9 kg/m2; P = .001), energy from total fat (−7.0%; P = .006), and energy from saturated fat (−2.8%; P = .016). A significant intervention effect was reported for vegetable intake (0.4 servings per day; P = .001) at 6 months. No significant group differences were found at 6 or 12 months for HRQoL, cancer-related fatigue, fruit, fiber, or alcohol intake, or smoking. Conclusion The CanChange intervention was effective for improving physical activity, dietary habits, and body mass index in colorectal cancer survivors. The intervention is translatable through existing telephone cancer support and information services in Australia and other countries.

Full textAbstract:
Background: Metabolic syndrome (MetS) is the key risk factor for cardiovascular disease (CVD) development. However, lifestyle habits including high consumption of sugar-sweetened beverages (SSBs) contribute to its onset. The current study was aimed at investigating the association between SSBs consumption and MetS components among young adults aged 22 to 30 years. Methods: This was a cross-sectional study where a total of 596 young adults (307 females and 287 males) participated. Blood pressure, biochemical assessment, and anthropometric measurements were taken following protocols. A validated 24 h recall questionnaire and food manuals were used to collect SSBs data. Binary logistic regression was applied to determine the association between SSBs consumption and MetS components. Results: In males, high SSBs consumption increased the risk of high fasting blood glucose (FBG) (p < 0.05). In females, high and low SSBs consumption decreased the risk of reduced high-density lipoprotein cholesterol (HDL-C), whereas only high SSBs consumption was associated with decreased risk of high triglycerides (TG) (p < 0.05). In conclusion, high TG, reduced HDL-C and high FBG was significantly associated with high consumption of SSBs. Longitudinal studies are recommended to further investigate the extent to which SSBs influences components of MetS.

AbstractObjective:Agriculture accounts for around 70 % of global freshwater withdrawals. As such, the food system has been identified as a critical intervention point to address water scarcity. Various studies have identified dietary patterns that contribute less to water scarcity. However, it is unclear what level of reduction is necessary to be considered sustainable. The pursuit of unnecessarily aggressive reductions could limit dietary diversity. Our objective was to assess the sustainability of water use supporting Australian dietary habits and the adequacy of current dietary guidelines.Design:Dietary intake data were obtained from the National Nutrition and Physical Activity component of the Australian Health Survey. For each individual daily diet, the water scarcity footprint was quantified, following ISO14046:2014, as well as a diet quality score. Water scarcity footprint results were compared with the planetary boundary for freshwater use downscaled to the level of an individual diet.Setting:Australia.Participants:9341 adults participating in the Australian Health Survey.Results:Dietary water scarcity footprints averaged 432·6 L-eq (95 % CI 432·5, 432·8), less than the 695 litres/person per d available to support the current global population of 7·8 billion, and the 603 litres/person per d available for a future population of 9 billion. Diets based on the Australian Dietary Guidelines required 521 L-eq/d, or 379 L-eq/d with lower water scarcity footprint food choices.Conclusions:Diets based on the Australian Dietary Guidelines were found to be within the freshwater planetary boundary. What is needed in Australia is greater compliance with dietary guidelines.

OBJECTIVE To analyze the factors associated with breastfeeding duration by two statistical models. METHODS A population-based cohort study was conducted with 86 mothers and newborns from two areas primary covered by the National Health System, with high rates of infant mortality in Vitória, Espírito Santo, Brazil. During 30 months, 67 (78%) children and mothers were visited seven times at home by trained interviewers, who filled out survey forms. Data on food and sucking habits, socioeconomic and maternal characteristics were collected. Variables were analyzed by Cox regression models, considering duration of breastfeeding as the dependent variable, and logistic regression (dependent variables, was the presence of a breastfeeding child in different post-natal ages). RESULTS In the logistic regression model, the pacifier sucking (adjusted Odds Ratio: 3.4; 95%CI 1.2-9.55) and bottle feeding (adjusted Odds Ratio: 4.4; 95%CI 1.6-12.1) increased the chance of weaning a child before one year of age. Variables associated to breastfeeding duration in the Cox regression model were: pacifier sucking (adjusted Hazard Ratio 2.0; 95%CI 1.2-3.3) and bottle feeding (adjusted Hazard Ratio 2.0; 95%CI 1.2-3.5). However, protective factors (maternal age and family income) differed between both models. CONCLUSIONS Risk and protective factors associated with cessation of breastfeeding may be analyzed by different models of statistical regression. Cox Regression Models are adequate to analyze such factors in longitudinal studies.

Type 2 diabetes mellitus (DM2) predisposes to an increased production of free radicals and a probable reduction in plasma antioxidants, including vitamin E. This cross-sectional study investigated the relationship between plasma alpha-Tocopherol concentration and vitamin E intake in 58 Brazilians with DM2. Plasma alpha-Tocopherol was determined by high-performance liquid chromatography. The intake of vitamin E-rich foods was assessed by a food frequency questionnaire. Total cholesterol and fractions were measured by colorimetric enzymatic methods. Data on demographic and socioeconomic factors, life habits, and anthropometry were obtained by a questionnaire and physical examination. The association between plasma alpha-Tocopherol and vitamin E intake was assessed by multiple linear regression analysis. The following variables were included in the regression model: alpha-Tocopherol, vitamin E intake, total cholesterol and fractions, body mass index, waist circumference, gender, age, education, occupation, income, smoking, alcohol intake, and blood pressure. There was no association between alpha-Tocopherol and vitamin E intake, but there were significant associations between alpha-Tocopherol and total cholesterol (p < 0.001) and waist circumference (p = 0.003). There were 36.2 % diabetics with low alpha-Tocopherol concentrations (< 12 µmol/L) and 32.7 % with a low alpha-Tocopherol/total cholesterol ratio (< 2.2). Further large, epidemiological, longitudinal studies, including measurements of gamma-tocopherol in blood, should be conducted to confirm our results.

Full textAbstract:
Nutrients, foods, and dietary components have a significant role in the development and maintenance of depressive disorders as well as the intensity of depression symptoms. Nutritional elements may alter the biomarkers linked to depression and may also influence the onset of depression, obesity, and diabetes. Recent research has identified novel mediators of mood fluctuations and energy balance that operate the gut-brain networks. In this context, a number of healthy foods including olive oil, fish, fruits, vegetables, nuts, legumes, poultry, dairy, and unprocessed meat, have been shown to have a negative correlation with the risk of depression and may even help with the symptoms of depression. The use of sweetened beverages, processed foods, fried foods, processed meat, refined grains, high-fat dairy products, biscuits, snacks, and pastries, on the other hand, has been linked in longitudinal studies to an elevated risk of depression. Nevertheless, it is usually challenging to draw a firm conclusion about a true prospective causal association from this primarily retrospective research since depressed people may also alter their eating habits incidentally as a result of their sadness. Additionally, it has been suggested that some dietary substances, including as calcium, chromium, folate, PUFAs, vitamin D, B12, zinc, magnesium, and D-serine, might be utilised as add-on treatments with antidepressants. In this situation, food and lifestyle changes may be a desired, practical, effective, and non-stigmatizing depression preventive and treatment option. In early randomized controlled clinical studies, a number of drugs that have historically been used to treat metabolic disorders—including pioglitazone, metformin, exenatide, atorvastatin, and gram-negative antibiotics showed some promise for treating depression.

We document a human-dolphin interaction involving the illegal feeding of wild Bottlenose Dolphins (Tursiops sp.) in Cockburn Sound, Western Australia from 1993-2003. In 1993 only one dolphin was considered conditioned to human interaction through food reinforcement. By 2001, 16% (n = 12) of the resident community of 74 adult dolphins were conditioned, and at least 14 dolphins were conditioned by 2003. Of the 13 conditioned dolphins of known sex, 11 (85%) were males. We observed conditioned dolphins initiating interactions by approaching recreational fishing boats and by residing for several hours at boat ramps and shore-based fishing sites. We only observed recreational fishers feeding dolphins, although anecdotal reports indicated additional feeding sources. We used belt transects to determine the densities of recreational boats and encounter rates for conditioned dolphins across habitats within Cockburn Sound. Encounter rates and boat densities were positively correlated, suggesting an association between recreational boat density and the ranging patterns of conditioned dolphins. This study demonstrates how illegal feeding interactions can intensify over time to affect a potentially biologically significant proportion of a local dolphin population. This emphasizes the need for early and pro-active intervention and demonstrates the value of longitudinal, individual-specific wildlife studies.

Background Few longitudinal studies have investigated the association between foods/dietary pattern and mortality risk in the Asian population. We investigated the prospective association between foods/dietary pattern and risk of death among ethnic Chinese adults in Taiwan. Methods The study population included 2475 young and middle-aged adults (aged 18–65 years at baseline) who completed the questionnaires and physical examinations in the Nutrition and Health Survey in Taiwan from 1993 to 1996. A food frequency questionnaire was administered to assess food consumption habits in a face-to-face interview. With survey data linked to the Taiwanese Death Registry, Cox proportional hazard model was used to identify the foods associated with all-cause mortality(followed until 2012), which were then tallied to calculate a dietary pattern score called Taiwanese Eating Approach(TEA) score. The TEA scores were then associated with various kinds of mortality outcomes. In addition, data from 431 elders (aged≥65 yrs) with 288 death endpoints were used to conduct a sensitivity analysis. Results A total of 385(15.6%) participants died (111 cardiovascular related deaths and 122 cancer related deaths) during the 17.8-year follow-up period(41274 person-years). Twelve foods (9 inverse [vegetables/fish/milk/tea](+1) and 3 positive[fatty meats/fermented vegetables/sweet drinks](-1)) were significantly associated with all-cause mortality risk. All adults were grouped by their cumulative food score into three diet groups: poor diet(29.3% of all subjects), average diet(44.0%), and healthy diet(26.70%). The better the diet, the lower the total, cardiovascular, and other cause mortality outcomes (trend-p < .001). The hazard ratio for the healthy diet was 0.64 (95% confidence interval:0.47–0.87) for total mortality, and 0.52(0.28–0.95) for cardiovascular death, compared with the poor diet in the multivariable models. This phenomenon was also seen in older adults for all-cause, cancer, and other cause mortalities. Conclusion Consuming a healthy Taiwanese Eating Approach (TEA) diet is negatively associated with all-cause, cardiovascular, and other-cause mortalities in Taiwan.

AbstractObjectiveTo investigate and report the diet quality of young Australian women by pregnancy status.DesignPregnancy status was defined as pregnant (n 606), trying to conceive (n 454), had a baby in the last 12 months (n 829) and other (n 5597). The Dietary Questionnaire for Epidemiological Studies was used to calculate diet quality using the Australian Recommended Food Score (ARFS) methodology. Nutrient intakes were compared with the Nutrient Reference Values for Australia and New Zealand.SettingA population-based cohort participating in the Australian Longitudinal Study on Women’s Health (ALSWH).SubjectsA nationally representative sample of Australian women, aged 25 to 30 years, who completed Survey 3 of the ALSWH. The 7486 women with biologically plausible energy intake estimates, defined as >4·5 but <20·0 MJ/d, were included in the analyses.ResultsPregnancy status was not significantly predictive of diet quality, before or after adjusting for area of residence and socio-economic status. Pregnant women and those who had given birth in the previous 12 months had marginally higher ARFS (mean (se): 30·2 (0·4) and 30·2 (0·3), respectively) than ‘other’ women (29·1 (0·1)). No single food group accounted for this small difference. Across all pregnancy categories there were important nutrients that did not meet the current nationally recommended levels of intake, including dietary folate and fibre.ConclusionWomen do not appear to consume a wider variety of nutritious foods when planning to become pregnant or during pregnancy. Many young Australian women are failing to meet key nutrient targets as nationally recommended.
