Cross-sectional study set up in 2004-2005 for the purpose of evaluating dietary habits and nutritional status of food-aid program beneficiaries. This study used several food-aid program structures (eg, subsidized groceries, food/meal distribution centres) in 4 urban areas (Paris, Seine-Saint-Denis, Dijon and Marseille). A random sample of 1 164 food-aid beneficiaries (aged 18+ years) was recruited. We collected data socio-demographic and economic characteristics, food supply sources including food-aid programs and frequency of consumption of the major food groups/nutrients. We also conducted clinical examinations and blood sample collection in public health centres.
