VASCONCELOS, Vera Lucia de and SILVA, Giselia A. P. da. Overweight and obesity prevalences in male adolescents in Northeast Brazil, 1980-2000. Cad. Saúde Pública [online]. 2003, vol.19, n.5, pp. 1445-1451. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2003000500023.
This study aimed to determine the prevalence rates for overweight and obesity among male adolescents in the States of Northeast Brazil from 1980 to 2000, and to compare them over time to identify trends. The Brazilian Army database was used, with information on 316,925 adolescent conscripts. Overweight was defined as body mass index (BMI) from 25 to 29.9Kg/m² and obesity as BMI > 30Kg/m². An upward curve was identified, showing that the secular tendency in the last twenty years increased for both overweight and obesity. The upward trend in overweight and obesity prevalence rates was observed in all States of Northeast Brazil. Although lower prevalence rates were observed than in developed countries, the speed of increase is cause for concern.
