ELANS is a multicenter cross-sectional study of nutrition and health of a national representative sample of urban populations from eight Latin American countries (Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela). A standard study protocol was designed to assess nutritional intake, physical activity levels, and anthropometric measurements of 9,000 enrolled participants.
The study was based on a complex and multistage sample design and the sample was stratified by sex, age (15 to 65 years), and socioeconomic level. A small-scale pilot study was conducted in each country to test the procedures and tools.
