Brazilian surveys provide an excellent opportunity to assess the relationship of adult BMI to a variety of social, economic and nutritional factors. Two surveys are used for the present paper. The first is the ENDEF (Escudo Nacional da Despesa Familiar) survey conducted in 1974-75 and the second is the PNSN (Pesquisa Nacional de Sa Nutri) survey of 1989.

Under the technical guidance of the Food policy and Nutrition Division of the United Nations Food and Agriculture Organization (FAO), the National Institute of Statistics and Geography of Brazil (IBGE) undertook a national food consumption and household expenditure survey (ENDEF) in 1974-75. More than 55 000 households were selected and interviewed and their food consumption and expenditure patterns were carefully monitored during a 1 week period. Many other types of related data were collected (anthropometry of household members, meal attendance, income and assets, etc.) and stored in a complex data bank to provide information for the National Accounts System as well as for other users (agriculture, health and social sectors).
