Relações entre comportamento sedentário e dieta dos adolescentes da rede pública de ensino de João Pessoa - PB.

Abstract

In the last decades, children and adolescents have become less active, induced by technological advances, spending more time on passive activities, such as watching television, using a computer and playing video games. These behaviors are linked to the consumption of foods high in calories, low in nutrients and high in fat, which affects health. The present study had objective to analyze the relationship between sedentary behavior and diet of the adolescents of the João Pessoa's public network of education. This is a cross-sectional study carried out with data from the first year of the cohort study: "Longitudinal Study on Sedentary Behavior, Physical Activity, Feeding and Adolescent Health" (LONCAAFS), carried out with 1384 adolescents, from the 6th year of primary education II, of both sexes, enrolled in public schools in the city of João Pessoa-PB, in 2014. The socio-demographic variables and sedentary behavior were analyzed through questionnaires and the diet through a 24H Dietary Record. There was no significant difference between the number of boys and girls, with 64.8% being aged ≥ 12 years, 80.9% of non-white skin color. As for the mother's schooling, 40.5% did not finish elementary school. Regarding the socioeconomic class, 65.5% were in classes C, D, or E. The prevalence of sedentary behavior was 76.8%. . The average energy consumed daily by adolescents was 2032.0 Kcal ± 1024.72. For carbohydrates the average percentage consumed was 57.0% ± 9.79, for proteins, 15.7% ± 5.14, for total fat, 27.82 ± 7.96, and for saturated fat, 7.11% ± 3.80, the which represents an adequate distribution of macronutrients. Relating to diet with sedentary behavior, it was observed that for total fat, 43.2% of the adolescents who were in sedentary behavior presented an inadequate consumption of this. No association was statistically significant. It is suggested that the longitudinal data be evaluated to see if there is any association over time between these variables.
