BackgroundTeenage pregnancy is becoming one of the most common social and public health problems worldwide, with the highest prevalence in sub-Saharan Africa. Health risks and adverse outcomes of pregnancy and childbirth among adolescent girls are the commonest cause of the global burden of maternal morbidity and mortality. This study is intended to determine the pooled prevalence and determinants of teenage pregnancy in sub-Saharan Africa using the most recent demographic and health survey data (2019–2022).MethodsA cross-sectional study was conducted using data from the most recent demographic and health surveys of four countries (Kenya, Tanzania, Gabon, and Cameroon) in sub-Saharan Africa conducted between 2019 and 2022. A total weighted sample of 12,829 teenagers aged 15 to 19 years was included in the study. Data extracted from demographic and health survey data sets were cleaned, recorded, and analyzed using STATA/SE version 14.0 statistical software. Multilevel mixed-effects logistic regression was used to determine the factors associated with the dependent variable. Finally, variables with a p-value ≤ 0.05 and an adjusted odds ratio with a 95% confidence interval were declared statistically significant.ResultsThe pooled prevalence of teenage pregnancy among women aged 15 to 19 years was 18.15% (95% CI: 17.49, 18.83). Teenage pregnancy was positively associated with the respondent’s age [AOR = 2.97; 95% CI (2.55, 3.46)], educational status [AOR = 2.21; 95% CI (1.62, 3.03)] and [AOR = 1.80; 95% CI (1.54, 2.12)], wealth status [AOR = 2.61; 95% CI (2.12, 3.22)] and [AOR = 1.65; 95% CI (1.33, 2.05)], relation to the household head [AOR = 2.09; 95% CI (1.60, 2.72)], and unmet need for contraception [AOR = 14.3; 95% CI (11.5, 17.8)]. On the other hand, it was negatively associated with marital status [AOR = 0.08; 95% (0.07, 0.10)], working status [AOR = 0.75; 95% CI (0.64, 0.88)], age at first sex [AOR = 0.68; 95% CI (0.58, 0.80)], contraceptive use [AOR = 0.25; 95% CI (0.20, 0.30)], contraceptive knowledge [AOR = 0.27; 95% CI (0.19, 0.40)], and community contraceptive utilization [AOR = 0.85; 95% CI (0.73, 0.99)].ConclusionIn the current study, one out of six young women aged 15 to 19 experienced teenage pregnancy. Therefore, addressing unmet needs for family planning, improving women’s educational status, and giving special attention to teenagers with low educational and economic status are recommended.
