Brazilian school-based survey of adolescent health: food intake markers, by geographical region, in the 2019 PeNSEA cross-sectional study was conducted with data from the 2019 National School Health Survey (n = 129,922) to examine the prevalence of intake of healthy and unhealthy marker foods in adolescents, by school administration type (public or private) and geographic region. Using Poisson regression, prevalence and crude-to-adjusted prevalence ratios were estimated, by sociodemographic variables, school administration type and geographic region. Adolescents at private schools returned lower prevalences of intake of beans (PRadj = 0.88; 95%CI = 0.86-0.90) and soft drinks (PRadj = 0.93; 95%CI = 090-0.97) and higher intake of fruit (PRadj = 1.06; 95%CI = 1.04-1.09) and vegetables (PRadj = 1.09; 95%CI = 1.07-1.12) than those at public schools. Fruit and vegetable intake was significantly higher in the South (PRadj = 1.28; 95%CI = 1.24-1.32) and Midwest (PRadj = 1.17; 95%CI = 1.13-1.20) regions. The Midwest region returned the highest prevalences of intake of soft drinks (PRadj = 1.40; 95%CI = 1.33-1.46) and sweet treats (PRadj = 1.24; 95%CI = 1.20-1.28). Adolescents at private schools were better protected by healthy consumption, while, by region, those in the Midwest, South and Southeast were more exposed to less healthy consumption.
