RESUMO
INTRODUCTION: Prevalence of adolescent sexual activity is on the increase globally, resulting in increased risk of adverse reproductive health outcomes among them. Sources of sex information are key factors that influence female adolescents' sexual decision-making. Consequently, this study is aimed at identifying adolescents' sources of sexuality information, and its likely effect on their sexual practices among in-school female adolescents in Osisioma LGA, in southeastern Nigeria. METHODOLOGY: A total of 304 girls selected by multi-stage sampling technique were studied. Responses were elicited from them using pretested, semi-structured, self administered questionnaire. Data were analyzed using MS Excel and Epi-6. FINDINGS: Primary and subsequent sources of sexuality information were mainly the media and peers. Families and schools mostly were not involved in provision of early sex education. Media and peer influence were predominantly negative. Female adolescents' knowledge of issues of sex was low. Premarital sex, early sexual initiation, and unprotected sex was common among them. Consequently, adverse implication of negative sexual behavior, such as unplanned pregnancies and induced abortion, was prevalent. CONCLUSION: The study highlights the need for increased roles of parents and teachers in early sexuality education of adolescent girls. This can be done by increasing capacity of parents to discuss sexuality issues with their children.
