Risky sexual behaviours, contraceptive use and associated factors among unmarried female adolescents in an urban municipality in Ghana.

In Ghana, few studies have focused on the link between risky sexual behaviours and contraceptive use among adolescents. Based on a survey of 260 randomly sampled unmarried adolescents, this study examined risky sexual behaviours and modern contraceptive use. Descriptive statistical analyses were performed in addition to bivariate and logistic regression models. Results show that 50.4% of respondents have had sex before, and many engaged in risky sexual behaviours: 48.8% have had two or more sexual partners in their lifetime; 21.4% have had sex while drunk; and 60.7% of those who reported having sex while drunk did not use a condom. Only 22.9% of sexually active adolescents ever used contraceptives. Factors that predicted use of contraceptives included being aged 17-19, knowing a place to get contraceptive, not having had drunk sex, and not feeling pressured to have unprotected sex. Public health education and self-efficacy interventions are needed to address risky sexual behaviours and improve contraceptive use.
