MAGALHAES, Vera Cristina; AZEVEDO, Gulnar  and  MENDONCA, Silva. Prevalence of overweight and obesity and associated factors among adolescents in the Northeast and Southeast regions of Brazil, 1996 to 1997. Cad. Saúde Pública [online]. 2003, vol.19, suppl.1, pp.S129-S139. ISSN 1678-4464.

The purpose of this study was to assess the prevalence and factors associated with overweight and obesity (OW/O) among Brazilian adolescents, based on the Living Standards Survey conducted in 1996 and 1997 (IBGE, 1998a). The sample included 1,027 and 854 adolescents aged 15 to 19 years from the Northeast and Southeast regions, respectively. Body Mass Index (w/h2) was calculated. Statistical analysis considered expansion factors and sample design. Prevalence of OW/O was 8.45% in the Northeast and 11.53% in the Southeast. In the Northeast there was a higher risk of OW/O for girls (PR = 3.00), with the same situation in both urban (PR = 3.21) and rural areas (PR = 2.27). In the Southeast, the risk of OW/O was lower among girls (PR = 0.58). The same situation occurred in girls from urban areas (PR = 0.51), but in rural areas there was an increased risk among girls (PR = 1.86). Per capita monthly income was associated with the risk of OW/O among boys in both regions. Programs to prevent OW/O should incorporate nutritional reeducation and encourage physical exercise, besides considering socioeconomic, cultural, and regional differences and the location of the target population.
