Factors influencing sexual risk behaviors among adolescents: A community-based participatory study.

Pregnancy rates and unprotected sex among Thai adolescents continue to increase. The aim of this community-based participatory study was to identify gender differences in sexual behaviors and sexual risk factors, and to examine factors associated with sexual risk behaviors among 397 adolescents in northern Thailand. Twenty two community researchers facilitated the data collection by using smart phones or tablet computers on a privacy basis. Ordinal and logistic regressions identified predictors influencing pre-coital behaviors and sexual behaviors. The results showed that males were more likely than females to engage in pre-coital and sexual behaviors. Significant predictors of higher pre-coital behaviors were age, sexual refusal self-efficacy, having boyfriends/girlfriends, authoritarian parenting style, parental approval of sex, and perceived peer norms. Pre-coital behaviors were positively correlated with sexual behaviors, and significant predictors of sexual behaviors were age, parent-adolescent communication, parental monitoring, perceived peer norms, and type of school. To better address the sexual risk behaviors of adolescents, we need to include key stakeholders to develop multi-modal culturally- and gender-specific sexual-prevention programs to account for information delivery, acceptability, and dealing with peer pressure.
