We aim to investigate the association between health risk behaviors (HRB), contextual, and relational characteristics of 9th-grade adolescents from schools in São Paulo, Brazil. Methods: Cross-sectional design study using survey data collected in 2017 by the São Paulo Project on Social Development of Children (sp-proso). The sample comprises 2,680 students from 119 public and private schools in the city of São Paulo. Our focus will be on the association of HRB with individual features, context (school disorder and degradation), and adolescents' relationships (with family and peers). Multilevel modeling and structural equation modeling will be performed to determine the relevant associations. Results: Our hypothesis is that HRB are more frequent in adolescents in school environments with higher disorder and degradation, with negative parenting styles, and who have delinquent peers. On the contrary, positive parenting styles and receiving social support are associated with lower levels of HRB. We count on this project results to outline a comprehensive framework of health behavior determinants that include contextual and relational data from Brazilian adolescents. Therefore, it will provide new evidence to support policy-making that can adequately face complex problems such as the establishment of HRB during adolescence. |
