ABSTRACT
This study examined the independent and combined associations of physical activity (PA) and sedentary behavior (SB) with health risk behaviors in Brazilian adolescents. Participants were 893 adolescents (454 girls) from Curitiba, Brazil. The Youth Activity Profile questionnaire evaluated PA and the Adolescent Sedentary Questionnaire evaluated SB. The Youth Risk Behavior Surveillance System ( YRBS) questionnaire evaluated fruit, vegetable, alcohol, and tobacco consumption. Binary Logistic regression measured the independent and combined associations of PA and SB with risk behaviors. PA was inversely associated with low fruit (OR = 0.30; 95%CI: 0.18-0.51) and vegetable consumption (OR = 0.43; 95%CI: 0.25-0.73), and tobacco use (OR = 0.52; 95%CI: 0.29-0.89). However, PA was positively associated with mild (OR = 1.54; 95%CI: 1.08-2.19) and excessive alcohol use (OR = 1.53; 95%CI: 1.01-2.33). Higher levels of PA were associated with reduced risks of smoking and healthier eating patterns, but higher likelihood of alcohol consumption
Este estudo examinou as associações independentes e combinadas de atividade física (AF) e do comportamento sedentário (CS) com comportamentos de risco à saúde em adolescentes brasileiros. Participaram do estudo 893 adolescentes (454 meninas) de Curitiba, Brasil. O questionário Youth Activity Profile avaliou a AF e o Questionário de atividades sedentárias dos adolescentes avaliou o CS. O questionário Youth Risk Behavior Surveillance System (YRBS) avaliou o consumo de frutas, vegetais, álcool e tabaco. A regressão logística binária avaliou as associações independentes e combinadas de AF e CS com comportamentos de risco. AF foi inversamente associado com baixo consumo de frutas (OR = 0,30; IC95%: 0,18-0,51), de vegetais (OR = 0,43; IC95%: 0,25-0,73) e uso de tabaco (OR = 0,52; IC95%: 0,29-0,89). No entanto, a AF foi positivamente associada com uso moderado (OR = 1,54; IC95%: 1,08-2,19) e uso excessivo de álcool (OR = 1,53; IC95%: 1,01-2,33). Níveis mais altos de AF foram associados com riscos reduzidos de fumar e padrões alimentares mais saudáveis e com maior probabilidade de consumo de álcool
