The fast spread of supermarkets and related shifts in diets were identified as possible factors contributing to overweight and obesity in developing countries. Potential effects of supermarkets on people's health have not been analyzed up till now. OBJECTIVE: This study investigates the effects of purchasing food in supermarkets on people's BMI, as well as on health indicators such as fasting blood glucose (FBG), blood pressure (BP), and the metabolic syndrome. DESIGN: This study uses cross-section observational data from urban Kenya. Demographic, anthropometric, and bio-medical data were collected from 550 randomly selected adults. Purchasing food in supermarkets is defined as a binary variable that takes a value of one if any food was purchased in supermarkets during the last 30 days. In a robustness check, the share of food purchased in supermarkets is defined as a continuous variable. Instrumental variable regressions are applied to control for confounding factors and establish causality. RESULTS: Purchasing food in supermarkets contributes to higher BMI (+ 1.8 kg/m2) (P<0.01) and an increased probability (+ 20 percentage points) of being overweight or obese (P<0.01). Purchasing food in supermarkets also contributes to higher levels of FBG (+ 0.3 mmol/L) (P<0.01) and a higher likelihood (+ 16 percentage points) of suffering from pre-diabetes (P<0.01) and the metabolic syndrome (+ 7 percentage points) (P<0.01). Effects on BP could not be observed. CONCLUSIONS: Supermarkets and their food sales strategies seem to have direct effects on people's health. In addition to increasing overweight and obesity, supermarkets contribute to nutrition-related NCDs. Effects of supermarkets on nutrition and health can mainly be ascribed to changes in the composition of people's food choices."],["dc.identifier.doi","10.1371/journal.pone.0185148"],["dc.identifier.pmid","28934333"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14829"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59043"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1932-6203"],["dc.relation.orgunit","Wirtschaftswissenschaftliche Fakultät"],["dc.relation.orgunit","Department für Agrarökonomie und Rurale Entwicklung"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0/"],["dc.subject.ddc","630"],["dc.subject.mesh","Adult"],["dc.subject.mesh","Blood Glucose"],["dc.subject.mesh","Blood Pressure"],["dc.subject.mesh","Body Mass Index"],["dc.subject.mesh","Cross-Sectional Studies"],["dc.subject.mesh","Fasting"],["dc.subject.mesh","Female"],["dc.subject.mesh","Food"],["dc.subject.mesh","Housing"],["dc.subject.mesh","Humans"],["dc.subject.mesh","Kenya"],["dc.subject.mesh","Male"],["dc.subject.mesh","Metabolic Syndrome X"],["dc.subject.mesh","Nutritional Status"],["dc.title","Supermarket purchase contributes to nutrition-related non-communicable diseases in urban Kenya."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Based on 24-hour recall data from rural households in Rwanda, Uganda and Tanzania, this study analyzes dietary patterns to provide a comprehensive picture of the risk of micronutrient deficiencies, with particular emphasis on bioavailable vitamin A, iron and zinc intakes. The results confirm that micronutrient deficiencies are widespread and positively correlated with calorie deficiency. Regression analysis suggests that income growth will bring about important nutritional improvements. However, more targeted interventions are needed, especially for controlling vitamin A deficiency. Promising avenues include basic education, women empowerment, promotion of home gardens, awareness campaigns and vitamin A biofortification. Spatial differences within and across regions indicate that detailed knowledge of local conditions is imperative for designing and targeting effective food and nutrition policies."],["dc.identifier.fs","580794"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/7436"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/61326"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.orgunit","Department für Agrarökonomie und Rurale Entwicklung"],["dc.relation.orgunit","Fakultät für Agrarwissenschaften"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.subject.ddc","630"],["dc.title","Patterns and determinants of dietary micronutrient deficiencies in rural areas of East Africa"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

This is especially true in Africa. There is an urgent need to make smallholder agriculture and food systems more nutrition-sensitive. African farm households are known to consume a sizeable part of what they produce at home. Less is known about how much subsistence agriculture actually contributes to household diets, and how this contribution changes seasonally. We use representative data from rural Ethiopia covering every month of one full year to address this knowledge gap. On average, subsistence production accounts for 58% of rural households' calorie consumption, that is, 42% of the calories consumed are from purchased foods. Some seasonal variation occurs. During the lean season, purchased foods account for more than half of all calories consumed. But even during the main harvest and post-harvest season, purchased foods contribute more than one-third to total calorie consumption. Markets are even more important for dietary quality. During all seasons, purchased foods play a much larger role for dietary diversity than subsistence production. These findings suggest that strengthening rural markets needs to be a key element in strategies to improve food security and dietary quality in the African small-farm sector."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2017"],["dc.identifier.doi","10.1371/journal.pone.0186406"],["dc.identifier.pmid","29049329"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/14847"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59055"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1932-6203"],["dc.relation.orgunit","Department für Agrarökonomie und Rurale Entwicklung"],["dc.rights","CC BY 4.0"],["dc.rights.uri","http://creativecommons.org/licenses/by/4.0/"],["dc.subject.ddc","630"],["dc.subject.mesh","Agriculture"],["dc.subject.mesh","Developing Countries"],["dc.subject.mesh","Diet"],["dc.subject.mesh","Ethiopia"],["dc.subject.mesh","Food Supply"],["dc.subject.mesh","Rural Population"],["dc.subject.mesh","Seasons"],["dc.title","Rural food security, subsistence agriculture, and seasonality."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
