Abstract Purpose To examine the relationship between adolescent sexual risk-taking and perception of parental monitoring, frequency of parent–adolescent communication, and parenting style. The influences of gender, age, and ethnicity are also of interest. Methods Data were collected from 7th–12th grade students in six rural, ethnically diverse school located in adjacent counties in a Southwest Lagos Nigeria. A 174-item instrument assessed adolescent perceptions, behaviors and attitudes. Youth who had engaged in sexual intercourse (n = 1160) were included in the analyses. Logistic regression analyses were conducted to identify parenting practices that predicted high versus low-risk sex (defined by number of partners and use of condoms). Variables included parental monitoring, parent–adolescent communication, parenting style, parenting process interaction effects and interaction effects among these three parenting processes and gender, age and ethnicity. Analyses included frequencies, cross-tabulations and logistic regression. Results Parental monitoring, parental monitoring by parent–adolescent communication and parenting style by ethnicity were significant predictors of sexual risk-taking. No gender or age interactions were noted. Conclusion Parental monitoring, parent–adolescent communication and parenting style are all important variables to consider when examining sexual risk-taking among adolescents. POSTED BY ABRAHAM
