ABSTRACT Objective: To evaluate the association between modifiable lifestyle behaviors and mental health indicators in Brazilian adolescents. Methods: This cross-sectional study used data from the 2019 National Survey of School Health including 152,860 students. The lifestyle behaviors and mental health indicators were obtained from a self-reported questionnaire. Logistic regression analyses were used to examine the association between lifestyle behaviors and mental health indicators. Results: Infrequent healthy eating (OR 1.22; 95%CI 1.14–1.31), being inactive (OR 1.82; 95%CI 1.65–2.01), smoking (OR 1.24; 95%CI 1.10–1.40), and irregular school attendance (OR 1.31; 95%CI 1.22–1.40) were associated with not having close friends. Additionally, not having close friends was also associated with unhealthy eating (OR 0.86; 95%CI 0.81–0.92) and alcohol consumption (OR 0.81; 95%CI 0.75–0.87). Infrequent healthy eating (OR 1.29; 95%CI 1.24–1.33), frequent unhealthy eating (OR 1.39; 95%CI 1.35–1.43), being inactive (OR 1.12; 95%CI 1.07–1.18), excessive screen time and sitting (OR 1.10; 95%CI 1.07–1.14 and OR 1.68; 95%CI 1.63–1.73, respectively), smoking (OR 1.26; 95%CI 1.19–1.34), alcohol (OR 1.33; 95%CI 1.28–1.37), drugs (OR 1.13; 95%CI 1.05–1.22), and irregular school attendance (OR 1.53; 95%CI 1.48–1.59) were associated with worse self-rated mental health. Conclusions: Various lifestyle behaviors are associated with different indicators of mental health.

RESUMO Objetivo: Avaliar a associação entre comportamentos modificáveis do estilo de vida e indicadores de saúde mental em adolescentes brasileiros. Métodos: Este estudo transversal utilizou dados da Pesquisa Nacional de Saúde do Escolar de 2019, incluindo 152.860 alunos. Comportamentos de estilo de vida e indicadores de saúde mental foram obtidos por meio de um questionário autoaplicável. Análises de regressão logística foram utilizadas para examinar a associação entre comportamentos de estilo de vida e indicadores de saúde mental. Resultados: Alimentação saudável infrequente (OR 1,22; IC95% 1,14–1,31), ser inativo (OR 1,82; IC95% 1,65–2,01), tabagismo (OR 1,24; IC95% 1,10–1,40) e frequência escolar inadequada (OR 1,31; IC95% 1,22–1,40) foram associados a não ter amigos próximos. Além disso, não ter amigos próximos também foi associado com alimentação não saudável (OR 0,86; IC95% 0,81–0,92) e consumo de álcool (OR 0,81; IC95% 0,75–0,87). Alimentação saudável infrequente (OR 1,29; IC95% 1,24–1,33), alimentação não saudável frequente (OR 1,39; IC95% 1,35–1,43), ser inativo (OR 1,12; IC95% 1,07–1,18), tempo excessivo em tela e sentado (OR 1,10; IC95% 1,07–1,14 e OR 1,68; IC95% 1,63–1,73, respectivamente), tabagismo (OR 1,26; IC95% 1,19–1,34), álcool (OR 1,33; IC95% 1,28–1,37), drogas (OR 1,13; IC95% 1,05–1,22) e frequência escolar irregular (OR 1,53; IC95% 1,48–1,59) foram associados a uma pior autopercepção de saúde mental. Conclusões: Vários comportamentos de estilo de vida foram associados a diferentes indicadores de saúde mental.
