Abstract Objectives We determined the prevalence of inadequate dietary intake of creatine and described nutritional profiles of individuals with low creatine intake in U.S. adults using data from the 2017–2018 National Health and Nutrition Examination Survey (NHANES) round. Methods Data for this study were obtained from the latest round of NHANES 2017–2018. Detailed dietary intake information from adult NHANES participants was obtained by dietary interview component through two 24-hour dietary recall interviews. To calculate creatine intake, we first identified meat-based protein foods using 8-digit USDA food codes organized in five database subgroups using dietary interview entry for individual foods. Next, we recorded the gram weight of each food/individual component containing meat-based protein, and calculated the net intake of meat-based protein for each respondent by merging all relevant food items on daily basis. Individual values for total grams of creatine consumed per day for each respondent were computed using the average amount of creatine (3.88 g/kg) across all sources of meat-based protein. A threshold for dietary intake of creatine was set at 1.00 gram per day, with respondents were classified into two subpopulations with the suboptimal intake of creatine (<1.00 g/day) or recommended intake (dietary creatine ³ 1.00 g/day). Results Among 4,004 NHANES adult participants that reported detailed dietary intake information, 2,611 (65.2%) were calculated to have dietary creatine intake below recommended levels of 1.00 g/day. The average daily creatine intake in this subpopulation was 0.52 ± 0.26 g (95% confidence interval, from 0.51 to 0.53). This was accompanied by a significantly lower dietary intake of meat-based protein, as compared to participants whose dietary creatine intake was equal to or above recommended levels (20.1 ± 10.2 g/day vs. 67.1 ± 30.4 g/day; P < 0.001). Conclusions The large-scale rate of suboptimal dietary creatine intake found in this cross-sectional study warrants additional research, and calls for immediate public health measures fostering creatine-rich foods in human nutrition.

AbstractObjectiveTo assess the overall diet quality of a sample of adolescents living in Alberta, Canada, and evaluate whether diet quality, nutrient intakes, meal behaviours (i.e. meal skipping and consuming meals away from home) and physical activity are related.DesignA cross-sectional study design. Students completed the self-administered Web-Survey of Physical Activity and Nutrition (Web-SPAN). Students were classified as having poor, average or superior diet quality based on Canada’s Food Guide to Healthy Eating (CFGHE).SettingOne hundred and thirty-six schools (37 %) within forty-four public and private school boards (75 %) in Alberta, Canada.SubjectsGrade 7 to 10 Alberta students (n4936) participated in the school-based research.ResultsOn average, students met macronutrient requirements; however, micronutrient and fibre intakes were suboptimal. Median CFGHE food group intakes were below recommendations. Those with poor diet quality (42 %) had lower intakes of protein, fibre and low-calorie beverages; higher intakes of carbohydrates, fat and Other Foods (e.g. foods containing mostly sugar, high-salt/fat foods, high-calorie beverages, low-calorie beverages and high-sugar/fat foods); a lower frequency of consuming breakfast and a higher frequency of consuming meals away from home; and a lower level of physical activity when compared with students with either average or superior diet quality.ConclusionsAlberta adolescents were not meeting minimum CFGHE recommendations, and thus had suboptimal intakes and poor diet quality. Suboptimal nutritional intakes, meal behaviours and physical inactivity were all related to poor diet quality and reflect the need to target these health behaviours in order to improve diet quality and overall health and wellness.

Full textAbstract:
Amid the trend of sustainable development, reducing food waste is a global concern and campaigns to reduce food waste have been launched. For example, the term “food sharing” has originated from Germany and promotes sharing food instead of wasting. “The Guerilla Kitchen”, which originated from Netherlands, is an organization that also promotes avoiding wasting food. Consequently, more and more people are paying attention on this issue and we think it is necessary to understand people’s acceptance of suboptimal food, as discarded suboptimal food represents a significant proportion of food waste. Additionally, at least one-third of the food globally produced each year is classified as suboptimal and cannot be sold in the market because of a poor appearance, damaged packaging, or near expiration date, thus presenting challenges for environmental, social, and economic sustainability. Previous studies on suboptimal food have focused more on appearances and packaging dates and less on investigating traceable agricultural and price discounts, which is where food classified as suboptimal entails a discount. Moreover, citrus product attributes such as appearance, size, freshness indicators, traceable agricultural products, and price discounts were determined in terms of consumer preference through pre-measurement here, then using a choice experiment method to clarify which attributes consumers care about most (N = 485 respondents). Conditional logistic regression and a random parameter logit model (RPL) are employed to examine the various properties of a marginal willingness to pay (WTP). RPL was also used to deduce the respondents’ choices based on differences in appearance and freshness indicator. The results showed that consumers place greater emphasis on the freshness indicators (harvesting/packaging date labels) and appearance of suboptimal citrus fruits but do not focus on the size. Consumers are willing to purchase citrus fruit with a flawed appearance, although the price needs to be reduced from the original price. Although suboptimal food does not reduce health, people may still not buy it and this result in food wastage. As a result, it is essential to increase awareness regarding suboptimal foods and reduce food waste to support sustainable development.

Full textAbstract:
Improving food sustainability and reducing food waste are among the top challenges for achieving global sustainable development. In particular, changes towards more sustainable consumption are of vital importance in creating a more sustainable world. To shed light on these issues, we analyze to what extent and how consumers’ food preferences move towards more sustainable behavior. We assess the importance consumers attach to the following critical sustainable attributes of food related to food waste: (i) “Visual imperfections”, (ii) “washed/unwashed”, (iii) “size”, (iv) “locally produced”, and (v) “price”. We hypothesize that consumer preferences for these attributes are heterogeneous. Therefore, we segmented consumers into homogenous groups according to preferences for these sustainability attributes. To do this, we employed a direct ranking preference method using data gathered in an experiment conducted with consumers living in a mid-sized town in the northeast of Spain in 2018. The results suggest a high degree of consumer heterogeneity, and we identified four clusters according to the importance consumers attach to these attributes. The results are encouraging for the promotion of sustainability because different groups of consumers might prefer to purchase food products with different sustainable characteristics, such as locally grown, foods with visual imperfections, and minimally processed foods.

Full textAbstract:
Reducing child malnutrition requires nutritious food, breastfeeding, improved hygiene, health services, and (prenatal) care. Poverty and food insecurity seriously constrain the accessibility of nutritious diets that have high protein quality, adequate micronutrient content and bioavailability, macrominerals and essential fatty acids, low antinutrient content, and high nutrient density. Diets based largely on plant sources with few animal-source and fortified foods do not meet these requirements and need to be improved by processing (dehulling, germinating, fermenting), fortification, and adding animal-source foods, e.g., milk, or other specific nutrients. Options include using specially formulated foods (fortified blended foods, commercial infant cereals, or ready-to-use foods [RUFs; pastes, compressed bars, or biscuits]) or complementary food supplements (micronutrient powders or powdered complementary food supplements containing micronutrients, protein, amino acids, and/or enzymes or lipid-based nutrient supplements (120 to 250 kcal/day), typically containing milk powder, high-quality vegetable oil, peanut paste, sugar, and micronutrients. Most supplementary feeding programs for moderately malnourished children supply fortified blended foods, such as corn–soy blend, with oil and sugar, which have shortcomings, including too many antinutrients, no milk (important for growth), suboptimal micronutrient content, high bulk, and high viscosity. Thus, for feeding young or malnourished children, fortified blended foods need to be improved or replaced. Based on success with ready-to-use therapeutic foods (RUTFs) for treating severe acute malnutrition, modifying these recipes is also considered. Commodities for reducing child malnutrition should be chosen on the basis of nutritional needs, program circumstances, availability of commodities, and likelihood of impact. Data are urgently required to compare the impact of new or modified commodities with that of current fortified blended foods and of RUTF developed for treating severe acute malnutrition.

Full textAbstract:
Purpose The increased acknowledgement of the problems associated with food waste has triggered a number of social and commercial initiatives for the re-distribution of suboptimal foods (SOFs). This paper aims to explore a variety of such initiatives and discuss their prospects, considering the commercial contingencies of the food supply system. Design/methodology/approach The exploration is based on a multi-country study of cases representing three initiatives related to the reduction of waste from SOFs, i.e. social supermarkets (SSMs), food banks and expiration date-based pricing practices. The collected data comprise expert interviews, store-check observations and secondary material; the data are analyzed from a marketing practice perspective. Findings The analyses indicate that the distribution and re-distribution of SOFs are moving toward normalization, that the diffusion of expiration date-based pricing through all food retailing formats is likely to continue, that food banks – despite reports of dwindling supplies of SOFs – are likely to increase their expansion and that SSMs face a variety of challenges, e.g. as regards their supply of SOFs and their customers’ preferences for stable assortments. Originality/value By synthesizing data from various European implementations of re-distribution practices, this article contributes to the understanding of the viability of such practices. Developing this understanding should benefit social and commercial entrepreneurs, as well as policymakers, when designing and implementing initiatives for the reduction of waste from SOFs.

Purpose: Dietary intakes and nutrition behaviours were examined among different diet quality groups of Canadian adolescents. Methods: This cross-sectional study included 2850 Alberta and Ontario adolescents aged 14 to 17, who completed a self-administered web-based survey that examined nutrient intakes andmeal behaviours (meal frequency andmeal consumption away from home). Results:Meanmacronutrient intakes were within Acceptable Macronutrient Distribution Ranges; however,micronutrient intakes andmedian food group intakes were below recommendations based on Canada's Food Guide to Healthy Eating (CFGHE). Overall diet quality indicated that 43%, 47%, and 10%of students had poor, average, and superior diet quality, respectively. Adolescents with lower diet quality had significantly different intakes of macronutrients and CFGHE-defined “other foods.” In terms of diet quality determinants, those with poor diet quality had higher frequencies of suboptimalmeal behaviours. Students with poor diet quality consumed breakfast and lunch less frequently than did those with average and superior diet quality. Conclusions: Canadian adolescents have low intakes of CFGHE-recommended foods and high intakes of “other foods.” Those with poor diet quality had suboptimal macronutrient intakes and increased meal skipping and meal consumption away from home. Adherence to CFGHE may promote optimal dietary intakes and improve nutritional behaviours.

Full textAbstract:
Background: With an estimated number of 1.2 billion in the world, adolescents represent a major transformative force in global health. Optimum adolescent nutrition is increasingly important for scaling up population health gains in low- and middle-income countries (LMICs) of South Asia. Nevertheless, little is known about the gender and socio-economic stratification of diets consumed by rural adolescents in these countries. The aim of this project was to understand the gender and socio-economic stratification of their diet with a dual, descriptive-analytic focus on dietary diversity (DD) and consumption of ultra-processed and deep-fried foods. Methods: This thesis builds upon cross-sectional analyses of data collected during 15-year follow-up of the MINIMat (Maternal and Infant Nutrition Interventions in Matlab) trial, from September 2017 to June 2019. Data on dietary and socio-demographic variables were collected through household survey; using a pre-tested, structured questionnaire. A single, 24-hour recall was employed to assess consumption of staples and non-staples arranged in 10 groups, ultra-processed foods (UPF) in four groups, and of one group of deep-fried foods. Data were analyzed using logistic regression models. The analytic sample comprised 2463 adolescents. Results: The prevalence of inadequate DD was 42.3% (40.3-44.2). Consumption of dark green leafy vegetables, vitamin A-rich fruits and vegetables, and animal-source foods–except fish–appeared low. The proportions of adolescents consuming meat, egg and dairy were higher among those from the richest households than those from the poorest households, and among boys than girls. Belonging to the poorest households (adjusted odds ratio (aOR): 1.59; 95% confidence interval (CI): 1.27-2.00) and the food insecure households (aOR: 1.34; 95% CI: 1.13-1.59), and attaining secondary education (aOR: 1.38; 95% CI: 1.11-1.71) were positively associated with inadequate DD. Adolescents having mothers with secondary education or above had lower odds of inadequate DD (aOR: 0.76; 95% CI: 0.60-0.96). Gender was not an independent predictor of inadequate DD.Approximately 83% (81.5-84.4) adolescents reportedly consumed at least one ultra-processed or deep-fried food in the 24 hours preceding the survey. Packaged confectioneries were the most consumed and sugar-sweetened beverages (SSB) the least consumed UPF group. Boys had greater odds of consumption than girls for all UPF groups and deep-fried foods. The association was strongest for SSB (aOR: 2.57; 95% CI: 1.97, 3.37), followed by deep-fried foods (aOR 1.96; 95% CI: 1.66, 2.32). Belonging to the richest households was associated with consumption of ready-to-eat foods (aOR 1.55; 95% CI: 1.12-2.16) and of SSB (aOR: 1.44; 95% CI: 1.02-2.03). Adolescents with higher educational attainment had lower odds of consuming SSB (aOR 0.73; 95% CI: 0.54-0.98). Conclusion: The studies presented compelling evidence of limited DD concurrent with emergent consumption of ultra-processed and deep-fried foods in a rural cohort of adolescents. Inadequate DD was more likely among those from the poorest and the food insecure households. For ultra-processed and deep-fried foods, gender association persisted across the food groups with boys having a greater likelihood of consumption than girls. Wealth status influenced consumption of “instant” foods and SSB only. This suboptimal dietary pattern may place the adolescents at heightened risk of different forms of malnutrition.

Full textAbstract:
Problematiken med matsvinn utgör ett globalt hållbarhetsproblem och konsumenternasbeteende har identifierats som den främsta bidragande faktorn till problematiken. En minskning av matsvinn måste ske för att en övergång till och utveckling av cirkulär ekonomi ska kunna realiseras, vilket ses som en direkt nödvändighet för att uppnå en hållbar utveckling. En förändring av de val konsumenter gör vid inköp av livsmedel ses som avgörande för att uppnå en minskning av det matsvinn som uppstår inom dagligvaruhandeln. Produkter med annorlunda utseende, kort utgångsdatum och skadad förpackning benämns som klass II-produkter, varpå en stor andel av dagligvaruhandelns matsvinn uppstår av just klass II-produkter. E-handel av mat har ökat drastiskt och utgör en viktig handelsplattform där det behövs åtgärder som syftar till att uppnå en förändring av konsumenternas beteende och val av livsmedel. Nudging utgör ett verktyg som används för att influera beteenden i en bestämd riktning och har identifieratssom en potentiell åtgärd att implementera inom dagligvaruhandelns e-handel, för att influera konsumenter att ta val av produkter som i en förlängning kan leda till minskat matsvinn. Syftet med denna studie är att utveckla förståelsen om vilka möjligheter och utmaningar det finns vid användandet av nudgingverktyg inom dagligvaruhandelns e-handel, för att influera konsumenters val av klass II-produkter. Val som i förlängningen kan leda till minskat matsvinn och utveckling av cirkulär ekonomi. För att utveckla denna förståelse, har vi utformat ett experiment som simulerar en fiktiv e-handel av dagligvaror, där olika nudgingverktyg implementerats i relation till klass II-produkter. Detta experiment har genomförts av studiens elva deltagare och därefter har dessa intervjuats. Den teoretiska bakgrunden om matsvinn, beslutstagande och nudging har ställts i relation till det material som samlats in genom intervjuerna, för att därefter användas för att besvara studiens problemformulering: Hur upplever konsumenter nudging i relation till klass II-produkter inom dagligvaruhandelnse-handel? Studiens resultat visar att konsumenternas upplevelse av nudging i relation till klass II-produkter inom dagligvaruhandelns e-handel, beror på konsumenternas preferenser, erfarenheter, förväntningar, konsumtionsmönster och ett antal demografiska faktorer. De största utmaningar och möjligheter för dagligvaruhandelns e-handel ses ligga i konsumenternas erfarenheter och preferenser, samt förverkligandet av transparens och tillit.

Full textAbstract:
Background Worldwide, one-third of all produced food is going to waste, and the number is increasing every year which consequently calls for action. A substantial share of the food waste is the outcome of grocery stores throwing away suboptimal food which yet is eatable but due to the date labeling, damaged packaging or in terms of appearance standards cannot be sold. Throughout the last years, numerous unique businesses have been formed in Sweden to offer suboptimal food both online and in physical stores. Still, Swedish grocery stores stand for 30 000 tons of food being wasted which is directly linked to the still evident unwillingness to offer, purchase and consume suboptimal food. By no means, this is a significant problem and need to be changed in order to reach a more sustainable world. Till this day, qualitative research on the topic is scare. Purpose The purpose of this thesis is to understand which components that affected Swedish grocery shoppers’ attitudes and purchase intentions towards suboptimal food in-store. Method In order to fulfil the purpose of this study, a qualitative methodology has been utilized. The qualitative data has been collected through semi-structured interviews amongst Swedish grocery shoppers. To explore the attitudes and purchase intentions towards suboptimal food product, an abductive research approach was applied to strengthen previous research findings and attempt to discover possible new theory. Conclusion The empirical findings revealed that Swedish grocery shoppers in this research study hold an overall positive attitude towards suboptimal food. The study further reports four prominent barriers towards Swedish grocery shoppers’ purchase intentions of suboptimal food. In result, even though an overall positive attitude presented, the intention to purchase suboptimal food could be severely weakened by substantial restrictions encountered in grocery stores.

The main goal of this study is to investigate stimulus that can be used to increase consumers purchase intentions toward suboptimal food products. Consumers seem to have low preferences to buy fruits and vegetables with unusual appearance, products with damaged package and close to the expiration date, usually called suboptimal food products. However, rejection of suboptimal food is an important contributor to food waste levels. Interventions aimed at encouraging the purchase of suboptimal food are scarce, however needed. This study used the theory of normative influence to test the effect of both descriptive and injunctive norms on a product with an unusual appearance, a product with a reduced expiration date and a product with a damaged package. The first study tested different messages appeals to create a realistic norm in study 2. From this study, it was selected the social message appeal and the frequencies of purchase toward each product, using them in the messages as the prevalent norm The second study analysed the effect of injunctive and descriptive norms of purchase intentions toward suboptimal food and also tested the effect of environmental concern and food waste problem awareness. Results show that both environmental concern and food waste problem awareness impact purchase intentions toward suboptimal food. Additionally, appeals employing social norms proved to affect purchases intentions toward these products. However, this effect only occurred for the vegetable with an unusual appearance and the product with a package damaged. For the product with a reduced expiration date the norms had no effect. Moreover, for the product with an unusual appearance, food waste problem awareness mediated the effect of injunctive norm on purchase intentions. Based on the results, this study contributes to the theory of normative influences by showing that, in a general way, this theory is applied to food waste reduction issues, more specifically, with suboptimal food consumption. However, it is necessary to consider the type of sub-optimally and the context where the influence is applied. Additionally, was discussed how social norms can be used to tackle food waste and the implications for marketing and policy actions.

In Europe, 45% of vegetables and fruit have been lost before consumption. The main reason for the loss is suboptimal food, which is perfect based on safety and security but imperfect according to appearance or packaging. In this project, I want to find out new possibilities in urban development by suggesting a participative food supply chain. It aims to inspire a paradigm of urban development and shift people’s attitudes towards suboptimal food. The participative supply chain includes food production, distribution, and retail/consumption. By participating in the food supply, residents and visitors can understand how the food system works, grow their food and help with food processing. With interaction and collaboration workers, they can value more about the food they consume and even change their eating patterns.

Full textAbstract:
Suboptimal growth and nutritional status are problematic for children with cystic fibrosis (CF). Optimal nutrition predicts better lung function and longevity. Daily nutrition therapy for children with CF requires adequate food resources, knowledge of appropriate nutrition and behavior management skills, and confidence in one's ability to correctly apply the necessary skills. The Mountain West Cystic Fibrosis Consortium Questionnaire (MWCFC-Q) was designed as an educational needs assessment for parents of children with CF. The goal was to identify areas of concern that could be targeted for educational intervention to ultimately improve children's growth and nutritional status.
Data analyzed from 305 returned surveys included household food security, use of food assistance programs, knowledge of nutrition and general CF therapy, and self-confidence in ability to manage CF care. Questions regarding food security and knowledge of CF nutrition and general therapies were multiple choice. A ten point Likert-type scale was employed for determining confidence around management of CF related issues.
Respondents' median accuracy for questions regarding nutrient content of commonly used foods was 71.4% and 57.9% for CF nutrition therapy, respectively. Although overall confidence in CF management was high, scores for confidence in nutrition and behavioral management were significantly lower than for confidence in CF respiratory/medical management and CF Center recommendations.
In the second phase of this project, a pilot study using the chronic care model was developed for enhancement of nutrition and behavior management skills of parents of children with CF. Participants attended a series of four classes, each with a short didactic presentation, group activity, and discussion. Important features of this evidence-based educational program included nutrition and behavior management, self-efficacy, problem solving skills, and peer mentoring. A pre-, post-, follow-up, follow-up format was used to evaluate changes in participants' knowledge and self-confidence regarding nutrition and behavioral management. Comparisons were made with responses to the mailed survey using the same questionnaire. Secondary outcomes were changes in the rate of weight gain and growth for participants' children with CF. Participants showed statistically significant improvement in knowledge of nutrition therapy for CF at post-intervention compared with respondents to the mailed survey.

Due to the serious global food waste problem, the World Food Programme (WFP) is advocating the food recovery plan, including purchasing suboptimal foods. However, previous studies related to the name, marketing, price or promotion of suboptimal foods in Taiwan are still under developed. Hence, this study aims to explode the relationships between purchase deterrents and purchase intention among three types of suboptimal foods, including visually abnormal vegetables and fruits, close-to-expiration-date products and damaged packaging food. A total of 471 valid questionnaires were collected from suboptimal foods’ purchasers in Taiwan. The results indicate that price, insufficient availability, risk perception and lack of trust significantly and negatively affect purchase intention. Moreover, product types contribute significant moderating effects on the relationship between purchase deterrents and purchase intention. For visually abnormal vegetables and fruits, price, risk perception and lack of trust significantly and negatively influence purchase intention; While for close-to-expiration-date products and damaged packaging food, lack of trust is the only crucial factor. These findings suggest that marketing managers shall emphasize on availability, obvious visibility and price discount according to different product types. Moreover, clear label with promotion may decrease consumers’ risk perception and enhance the trust, which might be applicable strategies to increase the purchase intention.

Food system and food safety have drawn spontaneous global attention due to effect of substantially environmental concerns. Three billion tons of food are wasted every year, estimated at a third of all produced food. The production of much of this waste is directly linked to the unwillingness to sell, purchase, and consume imperfect food that deviated from regular products in terms of appearance standards, date labelling, or damaged packaging. Yet empirical research on this issue is scarce. This study aims to develop an extended Theory of Planned Behavior (TPB) research model which includes environmental concern and involvement to predict consumers’ purchase intention to imperfect foods. A total of 246 respondents collected in Taiwan as data input. The empirical results of structural equation modeling (SEM) indicate that consumers’ attitude was the main predictor of their intention to purchase imperfect foods. Interestingly, this research showed that both perceived behavioural control and subjective norms were not significant predictors of intention. Furthermore, adding environmental concern and involvement as the additional constructs to the TPB significantly increased the explanatory power of the standard model. These findings provide important insights for imperfect food and useful recommendations for marketing channels, suggesting promotion of imperfect food may be the key of potential business.

Full textAbstract:
Copper is an essential trace mineral with a central role in oxidation#amp;#x2013;reduction reactions. It is involved in connective tissue formation and disulphide bonding of keratin. Clinical deficiency for copper is uncommon but has been increasing in prevalence, resulting from malnutrition or lack of trace metals in the food source, even in Western diets. Secondary copper deficiency can be induced by excess intake of zinc or iron and is sometimes seen in individuals taking supplements of these minerals. Copper requirements are increased in pregnancy, and suboptimal supply may have adverse effects on developing tissues and organ systems including the lung, skin, bones, and immune system. Despite the increased need, supplementation is generally not recommended in pregnancy. An increased intake of foods high in copper, such as nuts, and a proportionate lowering of low-copper foods (e.g. fats/oils) may be advisable in women with potentially marginal copper status.

Antioxidants are our first line of defense against free radical damage and are critical for maintaining optimum healthcare. Although most of the present day research is focused on the potential benefits of antioxidant nutrients or supplements, it has become clear that the best protection against oxidative stress involves a wide assortment of interrelated antioxidants and antioxidant cofactors. Additionally, the combination of several suboptimal concentrations of these kinds of detoxifying supplements may have an additive or even synergistic role to decrease the risk of some of diseases which are caused by aging. Adequate intake of fruit and vegetables have essential antioxidants like B-carotene and vitamin C, which are reported for decreasing the risk of cancer and coronary heart disease (CHD).

<em>Abstract.</em>—Many fishery management decisions continue to be guided by science only through “best guess” interpretation of assessment information and deterministic models of fisheries and food webs; until very recently this was true of nearly all fishery management in the Great Lakes. However, fishery management decisions can be improved by formally considering uncertainty when evaluating management options; practical tools for doing this have become increasingly available. Accounting for uncertainty is important because acting as though the best guess is true may be substantially suboptimal if this leads to poor performance for other less likely, but still plausible, “states of the world.” For a variety of critical Great Lakes fishery management issues, including determining appropriate investments in sea lamprey <em>Petromyzon marinus </em>control, setting suitable levels of salmonine stocking, and establishing percid harvest policies, are considered. In each case, the authors worked closely with fishery managers to conduct a decision analysis of management options they identified, using contemporary statistical methods to formally assess uncertainty about key fishery parameters and stochastic simulation to compare management options. These decision analyses were used by fishery managers to develop policies that more objectively account for uncertainty and to garner support from stakeholders and policy makers. The approach shows considerable promise for future fishery management in the Great Lakes, but may face substantial challenges as managers seek to more effectively involve stakeholders throughout the process, foster the requisite technical expertise within their agencies, and communicate the results of highly technical analyses to both stakeholders and decision makers. Three important aspects of salmon Arctic-Yukon-Kuskokwim region management for which a decision analysis approach would be particularly valuable are (1) the evaluation of different options for assessment sampling of returning adult salmon, used to determine whether escapement targets are being met; (2) strategies for in-season management of salmon harvest; and (3) setting annual escapement goals for individual stocks.

Cardiovascular diseases (CVDs) tend to occur in younger sub-Saharan African (SSA) populations, about 20 years earlier as compared to high income countries (HIC). Weak health systems and infrastructure, scarce cardiac professionals, skewed budget away from non-communicable diseases (NCD), high treatment costs and reduced access to health care. On top of that, hypertension diagnosis, treatment and control are low, less than 40%, less than 35% and 10-20% respectively. SSA has 23% of the worlds rheumatic disease, while 80% of CVD deaths occur in low to middle income countries. Poverty is not poverty. The rural–urban divide is one reality that has to be acknowledged among others, particularly in Africa. Being poor, while owning land and having the possibility to grow crops and rear livestock, goats and chickens, is different from being an unemployed young man or young woman, renting one room, in a crowded township with dilapidated infrastructure, intermittent or untreated water and surrounded by leaking sewers. Understanding the dynamics in different contexts is important for us to identify and address the different challenges affecting health in general, and heart health of people in these contexts in particular. For example, the detection, treatment and control rates of hypertension are higher in semi-urban as compared to rural areas. Detection rates for both men and women are suboptimal particularly in rural areas. Diet, sedentary life, loneliness and stress, insecure environments rather and unsafe places to walk are issues more common in urban settings. The conditions in which people are born, live, grow and work affect their health. The rural conditions are very different from the urban ones. The quality of air, access and types of food, stress levels, isolation, loneliness and fear not to mention violence, vary. All these factors affect heart health in one way or the other. Addressing heart health issues therefore ought to be context specific. The burdens might be treble or more for some -economically, environmentally (climate change, political instability), socially and historically-apartheid and colonialism.
