Obesity, as well as impaired lung function, is associated with significant morbidity and mortality. Few studies have evaluated the effect of adiposity on lung function in adolescents. This study was conducted to evaluate the effect of body mass index and sum of skinfolds (triceps and subscapular) on pulmonary function (forced expiratory volume in one second and forced vital capacity) of adolescents in the study there longitudinal live births in 1993, Pelotas - Brazil. Teenagers aged between 14 and 15 years were interviewed (n = 4349), follow-up rate of 85.7% of the original cohort, measured (n = 4110) and their lung function measured (n = 4006). It was observed through a cross-sectional analysis, after controlling for confounding factors during the gestational period, the body mass index presents. Overall direct effect on lung function while the sum of skinfolds opposite effect. The longitudinal analysis allowed us to observe that adolescents, regardless of sex, which remained in the lower tertiles of body mass index during follow-up had lower levels of lung function than those who remained in the middle tercile. The boys who remained in the highest tertile of skinfold thickness had lower lung function values. These findings suggest that low body mass index and the large sum of skinfold thicknesses have negative impact on lung function in adolescents.
