This study focused on the relationship between nutritional and socioeconomic status among adolescents in Niterói, Rio de Janeiro State, Brazil. Data from 523 adolescents living in 1,734 households were collected from January to December 2003, from a total of 71,922 adolescents living in Niterói. Subjects were selected through a probabilistic household sample. The analyses included the estimation of confidence intervals for prevalence ratios and proportional distributions and independence tests between categories of nutritional status and per capita family income and number of residents per household. There was a significant positive association between underweight/thinness and number of residents in the same household (male: p < 0.05; female: p < 0.001). Number of residents in the same household was positively associated with prevalence of underweight/thinness in adolescents. Overweight/obesity was positively associated with per capita family income.
