Fatores associados ao comportamento sedentário em escolares de 9-12 anos de idade

Abstract

Studies that investigated the impacts of sedentary behavior (SB) on health are recent, especially in children. The aim of this study was to investigate factors associated with SB in a Brazilian school in the city of Uberaba, State of Minas Gerais. This is an epidemiological study using cross-sectional probability sample (n=649). We collected and considered as independent variables: anthropometric measurements, blood pressure, biochemical, time spent in physical activity (PA). SD was considered the dependent variable, characterized by screen time (ST), and verified associated factors using Poisson regression analysis. Girls had higher skinfold, triglycerides and HDL-c, and boys have higher blood glucose concentration, attended more to the recommendation 60 min PA/day and higher SB. The TT > 2 h/day was prevalent in 76,9 % of the sample. SB was not associated with sociodemographic, health nor behavioral variables in 9- to 12-year-old school children. More research is necessary to identify the complex interrelationships between ST and associated factors.
