Abstract: Although low socioeconomic status (SES) adolescents suffer from higher rates of adverse sexual and reproductive health outcomes, evidence on the association between SES and sexual behaviors has been less consistent. A cross-sectional analysis of the association between sociodemographic characteristics (household wealth, maternal education and race/ethnicity) and sexual behaviors (sexual initiation, multiple sexual partners, inconsistent condom use and inconsistent contraceptive use) of Brazilian adolescents was carried out using the 2015 Brazilian National Survey of School Health (PeNSE), a nationally representative school-based survey of 102,301 adolescents. Analyses included multivariable logistic models, which accounted for geographic and family characteristics. About 27.5% of adolescents were sexually initiated. Household wealth was associated with female sexual initiation, while race/ethnicity was associated with condom use and multiple sexual partners among males. For instance, black males had 35% higher odds of having multiple partners (aOR = 1.35, 95%CI: 1.13-1.62), but 22% lower odds of condom use (aOR = 0.78, 95%CI: 0.65-0.94), compared to white males. Frequent parental supervision was positively related to condom use (females, aOR = 1.28, 95%CI: 1.10-1.49; and males, aOR = 1.33, 95%CI: 1.18- 1.49). Results show the complex relationship between SES and sexual behaviors. Researchers should pay attention to gender, racial and social norms salient to adolescent sexual behaviors, as they can influence data collection and results. National policies should also support active parental supervision, since it can be a protective factor.
