Movement behaviors of Brazilian adolescents and association with eating and lifestyle habits.

This study aimed to identify the associations between movement behaviors and food consumption, lifestyle, and health status (self-perception of health status and body image) of Brazilian adolescents. A cross-sectional study was conducted using data from the 2019 National School Health Survey regarding accumulated physical activity (PA) in different domains and sedentary behavior (SB) assessed by screen or television time. PA and SB were grouped and categorized into movement behavior profiles. Associations performed using Poisson regression were adjusted for sex, age, race or skin color, and maternal education; 95% confidence intervals were presented, and p<0.05 was considered significant. The adjusted analysis indicated that physically inactive adolescents with low screen time presented a low prevalence of consumption of unhealthy foods (PR=0.96), healthy foods (PR=0.97), buying food at the canteen (PR=0.94), consumption of alcoholic beverages (PR=0.94), and tobacco use (PR=0.92); however, this profile presented a high prevalence of eating in front of the screen (PR=1.11). Sedentary behavior was associated with variables in the domains of food consumption, lifestyle, and health status of Brazilian adolescents, regardless of the combined assessment of physical activity.
