Nutritional knowledge is an important cognitive facilitator that potentially helps children to follow a healthy diet. Two main information agents influence children’s development of nutritional knowledge: the media and their parents. While a high amount of media consumption potentially decreases children’s nutritional knowledge, parents may shape the amount of information children can gather about nutrition through their food-related mediation styles. In addition, children’s individual preconditions predict how children can process the provided nutritional information. This two-wave panel study with children (N = 719; 5–11 years) and their parents (N = 719) investigated the main effects and interplay of children’s amount of media consumption and their parents’ food-related mediation styles by performing linear regression analysis. Children’s individual preconditions were also considered. We measured children’s self-reported amount of media consumption, children’s age, sex, weight, and height (BMI). Additionally, in a parent survey we asked parents about how they communicate their rules about eating while especially focusing on active and restrictive food rule communication styles. As a dependent measure, we examined children’s nutritional knowledge at Time 1 and 2. The results show that the amount of media consumption has a negative effect on children’s nutritional knowledge over time. Parents’ restrictive or active food-related mediation asserted no main effects and could not lever out the negative effect of the amount of media consumption. Therefore, we argue that parents should limit children’s amount of media consumption to avoid the manifestation of misperceptions about nutrition.

This study was conducted to investigate effects of a horticultural activity program based on a mediating variable model for improving vegetable preference among elementary students. A quasi-experimental design was employed with 136 students and 136 primary carers in Seoul, South Korea. Based on the mediation model for improving children’s vegetable preference, 12 sessions were conducted, including gardening, nutrition education, and cooking activities using harvests. The program was conducted weekly for 12 weeks from March to July 2019. To investigate the effect of this program, mediating factors of the children were evaluated before and after the program. Pearson correlation analysis was used to identify the mediating factors. The nutrition index, attitude, knowledge, and eating habits of the primary carers were evaluated. Results showed children’s nutrition and gardening knowledge, dietary self-efficacy, outcome expectancies, and vegetable preference were significantly improved (p < 0.001). Primary carers showed significant improvement in the nutrition index, knowledge, and attitude (p < 0.05). The correlation analysis confirmed that most of the mediating factors had significant correlations (p < 0.05). Therefore, administering a structured program involving horticultural activities and nutrition education as mediating factors for 12 sessions was effective in improving eating behavior for vegetables elementary school students and primary carers.

This study aimed to determine whether smartphone addiction and depression sequentially mediate the relationship between body dissatisfaction and disordered eating behaviors (e.g., restrained eating, emotional eating and external eating). A total of 5986 participants (54.1% females, average age = 19.8 years, age range = 17–32) completed the Satisfaction and Dissatisfaction with Body Parts Scale, the Three-Factor Eating Questionnaire, the Smartphone Addiction Scale and the Patient Health Questionnaire-9. Mediational analysis showed that, after controlling for age, sex and body mass index, body dissatisfaction was related to disordered eating behaviors through (a) the mediating effect of smartphone addiction, (b) the mediating effect of depression, and (c) the serial mediating effect of smartphone addiction and depression. In conclusion, our study showed for the first time that smartphone addiction and depression can be sequential mediator variables in the association between body dissatisfaction and disordered eating. However, this study is a cross-sectional study; future longitudinal studies could further test the causal associations between these study variables.

ABSTRACT Background Early-life exposure to improved nutrition is associated with decreased risk of diabetes but increased risk of obesity. Leptin positively correlates with adiposity and has glucose-lowering effects, thus it may mediate the association of early-life nutrition and long-term glycemic status. Objectives We aimed to investigate the role of leptin in the differential association between early-life nutrition and the risks of obesity and diabetes. Methods We analyzed data from a Guatemalan cohort who were randomly assigned at the village level to receive nutritional supplements as children. We conducted mediation analysis to examine the role of leptin in the associations of early-life nutrition and adult cardiometabolic outcomes. Results Among 1112 study participants aged (mean ± SD) 44.1 ± 4.2 y, 60.6% were women. Cardiometabolic conditions were common: 40.2% of women and 19.4% of men were obese, and 53.1% of women and 41.0% of men were hyperglycemic or diabetic. Median (IQR) leptin concentration was 15.2 ng/mL (10.2–17.3 ng/mL) in women and 2.7 ng/mL (1.3–5.3 ng/mL) in men. Leptin was positively correlated with BMI (Spearman's ρ was 0.6 in women, 0.7 in men). Women exposed to improved nutrition in early life had 2.8-ng/mL (95% CI: 0.3, 5.3 ng/mL) higher leptin and tended to have lower fasting glucose (–0.8 mmol/L; –1.8, 0.2 mmol/L, nonsignificant) than unexposed women. There were no significant differences in leptin (–0.7 ng/mL; –2.1, 0.8 ng/mL) or fasting glucose (0.2 mmol/L; –0.5, 0.9 mmol/L) in men exposed to improved nutrition in early life compared with unexposed men. Leptin mediated 34.9% of the pathway between early-life nutrition and fasting glucose in women. The mediation in women was driven by improved pancreatic β-cell function. We did not observe the mediation effect in men. Conclusions Leptin mediated the glucose-lowering effect of early-life nutrition in women but not in men.

Social isolation has adverse effects on mental health, physical exercise, and dietary habits. This longitudinal observational study aimed to investigate the effects of mood states and exercise on nutritional choices, on 176 college students (92 males, 84 females; 23 ± 4 years old) during the COVID-19 lockdown. During 21 days, nutrition and exercise were daily monitored, and the mood states assessed. A factor analysis was used to reduce the number of nutritional variables collected. The relationships between exercise, mood and nutrition were investigated using a multivariate general linear model and a mediation model. Seven factors were found, reflecting different nutritional choices. Exercise was positively associated with fruit, vegetables and fish consumption (p = 0.004). Depression and quality of life were, directly and inversely, associated with cereals, legumes (p = 0.005; p = 0.004) and low-fat meat intake (p = 0.040; p = 0.004). Exercise mediated the effect of mood states on fruit, vegetables and fish consumption, respectively, accounting for 4.2% and 1.8% of the total variance. Poorer mood states possibly led to unhealthy dietary habits, which can themselves be linked to negative mood levels. Exercise led to healthier nutritional choices, and mediating the effects of mood states, it might represent a key measure in uncommon situations, such as home-confinement.

The article deals with the problem of mediation of social structural inequalities in health. According to theoretical explanations that require further empirical justification, inequalities in education — deterioration of health with its decline — may be associated with material deprivation. With a low educational status, a person does not have enough material resources necessary for high-quality nutrition, recreation and treatment. These inequalities may also arise due to the fact that poorly educated people lack the psychological reserves necessary for overcoming life's difficulties. Analysis of European Social Survey data (ESS 2012) for 27 countries, as well as the contextual factor of social protection expenditure was carried out using statistical methods of two-level modeling and regression models for mediation effects (HLM, MLmed macro, Process macro). Health inequalities in education are clearly manifest in any country. It was established that, along with education, material deprivations and especially personal resources play a significant role in differentiating the well-being of people, exerting an independent impact on it. According to the modeling results, in many countries, including the most developed, material deprivations that people with low levels of education suffer from, act as a mediator, partly clarifying the reasons for differences in health among people with different education. One of the lines of psychological mediation is also connected with material conditions — through two intermediaries, the first of which is deprivation, and the second is psychological qualities. At the same time, even when controlling all of these mediating effects, personal characteristics are an important mediator of SES inequalities, but not all over Europe, but only in countries with a relatively weak social state. In conclusion, a brief description of health inequalities and mediating effects in Russia is given.

Micronutrient malnutrition, also known as hidden hunger, continues to affect more than 2 billion people globally. Biofortification, which is a process of breeding staple crops with improved micronutrient contents such as vitamin A, iron, and zinc, offers a cost-effective and sustainable solution in reducing hidden hunger. However, the success of these foods depends on consumer acceptance. In contrast to previous studies, this research focuses on the mechanism of consumer acceptance of biofortified crops that undergo physical changes (i.e., changes in appearance) after biofortification. We use data on 473 Chinese consumers collected through online surveys to examine their purchase intentions for biofortified foods that have visible (vs. invisible) nutrition traits. Using two online surveys, we conduct two studies to reveal the mechanism and antecedents of consumer acceptance of different biofortified foods. In Study 1, we find that consumer purchase intentions vary depending upon the visibility of nutrition traits in biofortified foods. Specifically, consumers exhibit a nutrition-related food neophobia (NFN) regardless of visibility of the nutrition trait in biofortified foods; and a sensory-affective food neophobia (SFN) which is only pronounced when the nutrition trait in biofortified foods is visible. The results of the mediation analysis show that for both types of biofortified foods, NFN mediates consumers’ purchasing intentions. For foods that involve visible changes after biofortification, SFN acts as an additional mediator of consumer purchase intentions. Using ordered logistic regression analysis, we find that both food neophobias have a negative impact on consumer acceptance of biofortified foods. The results of Study 2 confirm our findings and further show that nutrition information moderates the mediation of NFN and SFN, i.e., the negative impact of NFN and SFN on purchase intentions can be reduced by providing nutrition information to consumers. The results of this study have several theoretical and practical implications and are of interest to stakeholders and marketers in the promotion of biofortified foods.

Purpose: To investigate the direct and indirect effects of sociodemographic/health factors on diet quality through practical nutrition knowledge (PNK) about how to compose a balanced meal. Design: A cross-sectional study using data from an online survey of the 10 000 Steps cohort (data collected November-December 2016). Setting: Australia. Participants: Adults (n = 8161). Response rate was 16.7%. Measures: Self-reported lifestyle, health, and sociodemographic characteristics, including diet quality and PNK. Analysis: The PROCESS macro for SPSS was used to conduct the mediation analyses. Results: Better diet quality was associated with being female, older, more highly educated, and having a lower body mass index. Mediation analysis showed that PNK significantly mediated the associations between sex (a*b = 0.54, 95% confidence interval [CI] = 0.39-0.70) and education (vocational education: a*b = 0.22, 95% CI = 0.12-0.35, university: a*b = 0.48, 95% CI = 0.35-0.64), and diet quality. Practical nutrition knowledge suppressed the association between age and diet quality (a*b = −0.03, 95% CI = −0.04 to −0.03). Conclusion: Variations in diet quality between sociodemographic groups were partially explained by differences in PNK, suggesting that focusing public health efforts on increasing this specific knowledge type might be promising.

Maternal nutrition and health status in the peri-pregnancy period are closely related to offspring health. Currently, population studies are unable to provide quantitative relationships and effective measures of peri-pregnancy high-fat diet and offspring myocardial remodeling due to the difficulty of obtaining human samples. This study aimed to establish the mouse models of maternal obesity and high-fat diet supplementation and deprivation during pregnancy. The effects of obesity, periconceptional high-fat diet window, fetal weight, sex, and placental weight on myocardial remodeling in the offspring were measured by single-factor and multiple-factor regression analyses. Moreover, the relationship between perinatal high-fat diet/fetal weight and offspring myocardial remodeling was explored using the mediation analysis model. The multivariate analysis showed that the heart weight to body weight (HW/BW) ratio of the offspring decreased by −1.6525 mg/g for every 1-g increase in fetal weight. The offspring HW/BW increased by 1.1967 mg/g if pregnant women were exposed to a high-fat diet throughout pregnancy. The mediation analysis model of a perinatal high-fat diet for the myocardial remodeling of offspring revealed that fetal weight had a suppression effect on the myocardial weight of offspring, accounting for 60.70%; also, it had a mediating effect on the HW/BW of offspring, accounting for 17.10%. Moreover, subgroup analysis showed an interaction between offspring sex and HW/BW in a maternal high-fat diet during pregnancy. Additionally, a quantitative real-time polymerase chain reaction experiment further proved that a perinatal high-fat diet could change the important indicators of myocardial remodeling in offspring. In conclusion, this study found that a high-fat diet in the periconceptional period influenced factors in offspring myocardial remodeling. Moreover, maternal high-fat diet deprivation attenuated the changes in offspring myocardial remodeling. In addition, the role of fetal weight in mediating maternal high-fat diet-mediated offspring myocardial remodeling was quantified. Our study showed that a sensible and healthy diet during the perinatal period, especially during pregnancy, played a positive role in the health of the offspring.

Nutrition can be viewed as a modifiable factor related to maintaining and preserving health in older adults. Previous studies have found that nutritional factors can influence cognitive abilities, however few studies have examined macronutrients and micronutrients as they relate to cognitive functioning. Research has yet to examine the mechanisms related to nutrition, cognition and aging in an older adult population from a holistic and interactive perspective.
This dissertation examined three research questions to better understand the relationship between age, nutrition, cognition, and inflammatory biomarkers. First, is nutrition related to cognition beyond demographic factors? Do individual nutrients serve as mediators? Second, are inflammatory biomarkers significant mediators to cognitive performance? Third, do nutrients and inflammatory markers interact as moderators to cognitive performance?
This study examined 1,317 adults 60 years and older from the National Health and Nutrition Examination Survey III (NHANES III). Macronutrients were collected from a retrospective 24-hour dietary recall, micronutrient values were obtained from blood serum/plasma for vitamin C, vitamin D, vitamin E, homocysteine, iron, folate, and inflammatory biomarkers values were obtained from blood serum/plasma for C-reactive protein, fibrinogen, and ferritin. Cognition was measured by 6 tasks: immediate and delayed word recall, immediate and delayed story recall, orientation, and digit subtraction. All tasks were then combined to form a global cognitive measure.
Results for question one found that after controlling for age, sex, education, and total calorie intake, higher intake of polyunsaturated fat was related to better global cognition and delayed story recall score (std β= .08, p= .028, std β= .08, p=.04 respectively). Greater than 28% of calories from carbohydrate indicated worse global cognition and delayed story recall (std β= -.013, p= .028, and std β= -.158, p= .01). Higher intake of saturated fat and protein were related to worse digit subtraction scores (std β= -.160, p= .02, std β= -.064, p= .02). Higher serum vitamin C, D, and folate levels were related to better global cognition and digit subtraction. Additionally, higher serum vitamin C and D were associated with better orientation score, and folate was related to better immediate and delayed story recall. Building from these relationships, individual mediation models found that serum vitamin C, vitamin D, folate, and ferritin were significant mediators between age and the previously mentioned cognitive tasks.
Results for question two examined mediation between inflammatory markers and cognition and found that higher fibrinogen was related to worse global cognition and digit subtraction. Higher ferritin was associated with better delayed word recall.
Question three investigated the moderating relationship between age, nutrients, and biomarkers, and results found that folate and fibrinogen were significant moderators. Higher serum folate was related to better global cognition and immediate story recall. Ferritin values below 1.2 and above 3.2g/l indicated worse digit subtraction performance. Evidence for a dose-dependent relationship was confirmed.
Results from this project demonstrated that select nutrients (polyunsaturated fat, vitamin C, D, and folate), and inflammatory markers (ferritin and fibrinogen) were associated with cognitive performance across various cognitive domains. Consuming a diet rich in healthy fatty acids, and antioxidants may be beneficial for cognitive health. Future studies should continue to examine the underlying mechanisms connected to maintaining, preserving, and protecting cognitive abilities in older adults.

La nutrition est un facteur de risque modifiable pour le cancer puisqu'environ un tiers des cas pourraient être évités en adoptant une meilleure alimentation. La relation entre nutrition et cancer est complexe, et son étude est enrichie par de nouveaux défis apportés par les récentes avancées technologiques dans le domaine des « -omiques ». Cette thèse a pour but de développer de nouvelles approches biostatistiques afin d'étudier la relation entre nutrition et cancer au sein de la cohorte EPIC. Pour ce faire, l'applicabilité de nouvelles méthodologies multivariées dans le domaine de l'épidémiologie nutritionnelle a été étudiée.Une nouvelle méthode multivariée pour la réduction de la dimensionnalité, le Treelet Transform (TT), a été examinée afin d'extraire des patterns de nutriments issus de questionnaires. Les patterns ainsi obtenus par le TT étaient plus facilement interprétables que par les méthodes classiques. Ensuite, un cadre analytique pour implémenter le concept du « meeting-in-the-middle » (MITM) a été développé et appliqué dans 2 études cas-témoin nichées sur le cancer hépatocellulaire avec des données métabolomiques. Le MITM cherche à identifier des biomarqueurs qui soient à la fois des marqueurs de certaines expositions passées et des prédicteurs de maladies. L'implémentation s'est focalisée sur l'application de la PLS et de l'analyse de médiation.Enfin, nous avons examinés la relation entre les niveaux plasmatiques de 60 acides gras issus de biomarqueurs et le risque de cancer du sein dans une étude cas-témoin nichée dans EPIC.Cette thèse servira de base pour des applications épidémiologiques futures examinant la relation nutrition-cancerDiet is a modifiable risk factor for many cancers. It has been estimated that about a third of cancer cases can be prevented by complying with a healthy diet and adhering to the recommendations in terms of nutrition. The nutrition-cancer relationship is a complex one, and its study is currently at a turning point with the opportunity and challenges brought by the recent technological advances in the fields of « -omics ».This thesis aims to develop new biostatistical approaches to investigate the nutrition-cancer relation within the European Prospective Investigation into Cancer and nutrition (EPIC) study. To do so, the applicability of new methodologies in the field of nutritional epidemiology has been examined.First, a new multivariate dimension reduction method, the Treelet Transform (TT) was applied to extract nutrient patterns relying on questionnaire data. The extracted patterns were more easily interpretable than those obtained with more classical methods.Then, an analytical framework was conceived for the « meeting-in-the-middle » (MITM) principle and applied to two nested case-control studies on hepatocellular carcinoma, with targeted and untargeted metabolomics data. The MITM aims to identify overlap biomarkers of certain exposures that are at the same time predictive of disease outcomes. The implementation focused on the application of partial least squares and mediation analyses. Last, the association between 60 plasma fatty acids levels assessed from biomarkers and breast cancer risk was examined in a nested case-control study in EPIC. This thesis will serve as a basis for future epidemiological applications looking into the nutrition-cancer relation

Objective: To evaluate the association of oral health on general health and whether food intake mediates the relationship. Method: Data were collected in 2004–06 in a representative sample of Australian adults from NSW and Queensland, using a three-stage, stratified clustered sample, involving a computer-assisted telephone interview (CATI), followed by an oral examination, mailed questionnaire and a food frequency questionnaire (FFQ). Self-rated general health was the outcome, and self-rated oral health, periodontal status, oral health impact (OHIP) and missing-teeth were explanatory variables, and food groups (dairy, bread-cereal, meat-fish-eggs, sweet foods-snacks, mixed-vegetables, vegetables and fruits) were mediators. Age, gender, smoking-status, brushing-habits, diabetes, alcohol-consumption and social-support were the control variables. For mediation analysis Baron and Kenny’s mediation analysis was initially performed, followed by Sobel’s test. Lastly bootstrapping for standard-error and Structural Equation Modelling (SEM) were conducted to assess the consistency of the mediation model. Result: A total of n =14,123 adults responded to the CATI (49% response rate), and n =5505 were examined. In the nutrition sub-study, a total of n = 1218 persons were approached, with n =1129 responding (92.7% response rate). Among them, there were 752 respondents who were aged 45 years or more. From multivariate linear regression analysis, It has been found that adults with better self-rated dental health rated their general health better (β=0.408, p<0.001). Worse oral health was associated with worse general health (for OHIP and missing-teeth, β= -0.027 and -0.01, p<0.001). Adults with none/mild and moderate periodontal problems compared to severe problems rated their general health better (β1=0.13, p<0.001 and β2=0.09, p<0.001). Baron and Kenny, and Sobel tests showed the associations between oral health (OHIP and missing-teeth) were partially mediated by food intake (Sobel test: for all mediators, p<0.001). The associations between periodontal status and self- rated general health were partially mediated by food intake (Sobel test: for all mediators, p<0.05). The association between self-rated dental health and general health was partially mediated by food intake (Sobel test: for all mediators, p<0.01). For all four explanatory variables, periodontitis, number of missing-teeth, OHIP-score and self-rated dental health, Bootstrap results showed zero in the bias-corrected confidence intervals for mediators, indicative of no mediation. SEM analysis for mediation between periodontal status and general health showed p= 0.76, p=0.045, p=0.050, p=0.015, p=0.73, p=0.42 and p= 0.30 for dairy, bread-cereal, meat-fish-eggs, sweet foods-snacks, mixed-vegetables, vegetables and fruits. SEM analysis for mediation showed p= 0.95, p=0.34, p=0.44, p=0.40; p= 0.04 and p=0.58 for dairy, bread-cereal, meat-fish-eggs, sweet foods-snacks, mixed-vegetables, vegetables and fruits respectively for OHIP and p>0.05 for dairy, bread-cereal, meat-fish-eggs, sweet foods-snacks, mixed-vegetables, vegetables and fruits for missing-teeth. SEM analysis for mediation between self-rated dental and general health showed p>0.05 for dairy, bread-cereal, meat-fish-eggs, sweet foods-snacks, mixed-vegetables, vegetables and fruits. Conclusion: SEM indicated the association between periodontitis and self-rated general health was partially mediated by bread-cereal, meat-fish-eggs and sweet-snacks. But the association between self-rated dental health, OHIP-Score or number of missing-teeth and self- rated general health was not mediated by any of these food items.Thesis (Ph.D.) -- University of Adelaide, Adelaide Dental School, 2019
