Various hypotheses link neighborhood food environments and diet. Greater exposure to fast food restaurants and convenience stores are thought to encourage overconsumption; supermarkets and large grocery stores are claimed to encourage healthier diets. For youth, empirical evidence for any particular hypothesis remains limited. This study examines the relationship between school and residential neighborhood food environment and diet among youth in California. Data from 8226 children (age 5–11) and 5236 adolescents (12–17) from the California Health Interview Survey are analyzed. The dependent variables are daily servings of fruits, vegetables, juice, milk, soda, high sugar foods, and fast food, which are regressed on measures of food environments. Food environments are measured by counts and density of businesses, distinguishing fast-food restaurants, convenience stores, small food stores, grocery stores, and large supermarkets within a specific distance (varying from 0.1 to 1.5 miles) from a respondent’s home or school. No robust relationship between food environment and consumption was found. A few significant results are sensitive to small modeling changes and more likely to reflect chance than true relationships. This correlational study has measurement and design limitations. Longitudinal studies that can assess links between environmental, dependent and intervening food purchase and consumption variables are needed. Reporting a full range of studies, methods and results is important as a premature focus on significant correlations may lead policy astray.
