Does meeting recommendations for physical activity, screen time, and sleep increase the chance of better health perception in adolescents?

Physical activity, sedentary behavior, sleep and health perception

Resumo

Aim: To analyze the possible associations of meeting isolated, combined, and integrated recommendations for moderate to vigorous physical activity, screen time, and sleep with health perception in adolescents. Methods: This is a cross-sectional, school-based epidemiological study with 576 adolescents (14-17 years old) enrolled in public schools in the Metropolitan Region of Recife, Pernambuco. Data were obtained through the Global School-Based Student Health Survey questionnaire. Binary logistic regressions were performed to analyze the association between meeting the recommendations and health perception. Results: Isolated meeting of recommendations were 29.7% for physical activity, 23.8% for screen time, and 27.3% for sleep. Combined meeting of recommendations was 8.5%, 6.1%, and 8% for “Moderate to Vigorous Physical Activity + Screen Time”, “Screen Time + Sleep” and “Sleep + Moderate to Vigorous Physical Activity”, respectively. Meeting two or more recommendations was associated with higher odds of having a “positive” health perception (OR = 2.03; 95% CI: 1.19;3.48). Meeting the physical activity recommendation (OR = 1.59; 95% CI: 1.01;2.50), the combined recommendation of screen time + sleep (OR = 2.42; 95% CI: 1.01;6.05) and meeting the combined recommendation of moderate to vigorous physical activity + sleep (OR = 3.35; 95% CI: 1.27;8.84) demonstrated an association with a positive health perception. Conclusion: Meeting two or more recommendations, only the physical activity recommendation, or the combination of “screen time and sleep” and “moderate to vigorous physical activity and sleep” increases the chances of positive self-perception of health in adolescents.
