[Food insecurity in households with adolescents in the Brazilian Amazon: prevalence and associated factors].

This cross-sectional population-based study in 2007 focused on prevalence of food insecurity and associated factors in households with adolescents in four towns in the Legal Amazonia located along highway BR-163, from Cuiabá, Mato Grosso State, to Santarém, Pará State, Brazil. The study applied the Brazilian Food Insecurity Scale to a sample of 363 households. Anthropometric assessment was performed on 534 adolescents from 10 to 19 years of age. A Poisson model was used in the multiple regression analysis. The results showed 23.1% prevalence of moderate to severe food insecurity, suggesting association with the following: low income, poor sanitation, head of household born in Mato Grosso State, and the adolescent's race (black). The results emphasize the need for improved access to basic sanitation, training of human resources to generate employment/income, and educational activities to improve understanding of food insecurity and its determinants.
