Early sexual debut among adolescent girls and young women in Sierra Leone: A multilevel analysis of prevalence and predictors

Abstract

Background Early sexual debut among young women is associated with adverse sexual and reproductive health outcomes, including unintended pregnancies and sexually transmitted infections. Despite its negative impact, there is limited research on this issue in Sierra Leone. This study aims to address this gap by examining the prevalence of early sexual debut and its associated factors among adolescent girls and young women aged 15–24 years in Sierra Leone. Methods Data from the 2019 Sierra Leone Demographic and Health Survey was used for the study. Provincial variations in the proportion of early sexual debut were visualised using a spatial map. A mixed-effect multilevel binary logistic regression analysis was performed to examine the factors associated with early sexual debut. The results were presented as adjusted odds ratios (aOR) with a 95% confidence interval (CI) and intraclass correlation coefficients. Results The prevalence of early sexual debut was 26.1% [24.3, 28.0]. Adolescent girls and young women aged 20–24 were less likely to engage in early sexual debut [aOR = 0.52; 95% CI: 0.41, 0.65] than those aged 15–19. The odds of early sexual debut was lower among adolescent girls and young women with secondary/higher education [aOR = 0.62; 95% CI: 0.45, 0.85] compared to those with no education. Adolescent girls and young women who used the internet in the last 12 months [aOR = 0.50; 95% CI: 0.34, 0.73] and those who belonged to the Fullah ethnic group [aOR = 0.25; 95% CI: 0.07, 0.85] were less likely to engage in early sexual debut relative to those who did not use the internet and those belonging to the Creole ethnic group respectively. Adolescent girls and young women who intend to use contraceptives [aOR = 0.60; 95% CI: 0.46, 0.77] and those who do not intend to use contraceptives [aOR = 0.65; 95% CI: 0.49, 0.88] were less likely to engage in early sexual debut than those who were using contraceptives. Conversely, adolescent girls and young women who were working [aOR = 1.41; 95% CI: 1.12, 1.77] had higher odds for early sexual debut than those not working. The odds of early sexual debut were higher among adolescent girls and young women who were married/cohabiting [aOR = 1.72; 95% CI: 1.32, 2.22] and previously married [aOR = 3.26; 95% CI: 1.61, 6.56] than those who were never married. Adolescent girls and young women living in the North Western area [aOR = 1.81; 95% CI: 1.05, 3.13] had higher odds for early sexual debut than those living in the Eastern province. Conclusion Early sexual debut is prevalent among adolescent girls and young women in Sierra Leone. Age, education, internet use, ethnicity, contraceptive use intention, marital status, employment status, and province of residence were the factors associated with early sexual debut. The study underscores the need for policymakers, government, and non-governmental organisations to design and implement comprehensive and multifaceted interventions...
