[Depressive symptoms during adolescence: a study on psychosocial factors in a sample of teenage students in a city in Rio de Janeiro State, Brazil].

This study's objective was to identify individual, social, and familial risk factors for depressive symptoms in adolescent students. The study included 1,923 seventh and eighth-grade (junior high) students and first and second-year high school students in public and private schools from a city in Rio de Janeiro State, Brazil. Depressive symptoms were evaluated with the SRQ-20 scale (Harding, 1980) and resilience scale (Wagnild & Young, 1993). Hierarchical logistic regression was the analytical method used. Symptoms of depression were present in 10% of adolescents. Girls had more than twice the odds of presenting these symptoms (CI: 1.58-3.67); adolescent children of divorced parents had 73% greater odds of depression (CI: 1.16-2.57); victims of serious physical abuse by mothers had 6.49 times the odds (CI: 2.07-20.30); those with low self-esteem, 6.43 greater odds (CI: 2.63-15.68); and those displaying dissatisfaction with their lives, 3.19 greater odds (CI: 2.08-4.89). The findings highlight the urgent need to improve public health policies for adolescents, especially at the preventive level, including psychosocial strategies with the development of a treatment network.
