The objective of this study was to determine the prevalence of anemia and vitamin A deficiency and to analyze the association of food insecurity with hemoglobin levels and serum retinol in children under 5 years of age. This was a cross-sectional study with 501 families from Gameleira and 458 families from São João do Tigre. Food insecurity was assessed according to the Brazilian Food Insecurity Scale. Hemoglobin and serum retinol levels were classified according to the WHO. Socioeconomic and environmental conditions and biological indicators of children were analyzed as hemoglobin and serum retinol determinants. The prevalence of anemia and vitamin A was higher in Gameleira compared to São João do Tigre. Moderate and severe food insecurity of families was 75% in Gameleira and 64% in São João do Tigre. Maternal education, per capita family income, not having a color TV, untreated water supply, type of flooring (dirt), and child age (&lt; 2 years) in Gameleira were associated with hemoglobin levels in the linear regression analysis. In São João do Tigre the association with hemoglobin levels was only for (no) motorcycle and child age. Variables per capita family income and sex in Gameleira and no mobile phone and lack of sanitation in São João do Tigre were statistically associated with serum retinol levels. The nutritional status of these populations is similar in terms of food insecurity but may present great differences in terms of the prevalence of specific nutritional deficits and their determinants.
