【 摘 要 】

Purpose: To estimate the prevalence and associated factors with insufficient leisure-time physical activity (ILPA) among adolescents from a medium-sized city in the state of Minas Gerais, Brazil. Methods: Data from the ACtVU cross-sectional survey (Uberaba - MG, Brazil) conducted between May and October 2015. High school students of both sexes (14 to 18 years old) comprised the sample. ILPA (< 300 minutes/week) was the dependent variable and sociodemographic, behavioral and health indicators were the independent variables evaluated through questionnaires. Binary logistic regression was used to estimate the Odds Ratio (OR). BMI was used as control variable. Results: 984 students participated in this study. The percentage of ILPA was 44.9% (95% CI 41.7; 48.1) and was higher among girls (57.1% vs. 29.3% in boys). Increased chance for ILPA was found in: the grade for both sexes (OR = 2.23 boys, OR = 2.28 girls), weekday screen time (OR = 1.29), excessive use of smartphone during the week (OR = 1.54) and at the weekend (OR = 1.22) among boys, studying tonight (OR=1.80), having a work (OR = 1.24), family income (OR = 1.41 for 3 to 5 minimum wages and OR = 1.65 for ≥ 6 minimum wages), weekday screen time (OR = 1.87) and dissatisfaction with the own weight (OR = 1.32) among girls. Conclusion: The prevalence of ILPA was high. Most of the associated factors were different in boys and girls.
