Teenage pregnancy and experience of physical violence among women aged 15-19 years in five African countries: Analysis of complex survey data

Background Pregnant teenage women are prime targets of violence against women perpetrated by intimate partners, family members, and miscreants in their neighborhoods. This study estimated the prevalence of Teenage pregnancy (TP) and Physical Violence (PV) and further assessed the relationship between TP and PV in five Low-and-Middle-Income Countries (LMICs). Methods The study was conducted among five LIMCs (Burkina Faso, Kenya, Malawi, Nigeria, and Tanzania) using data from the most recent Demographic and Health Surveys conducted in these countries. Modified Poisson with the robust standard error was used to quantify the association between TP and PV. All analyses adjusted for the complex survey design structure (clustering, weighting, and stratification). Results The analysis involved a total of 26055 adolescent women aged 15-19 years across the five countries. The overall prevalence of TP was 25.4% (95%CI = 24.4-26.4) with the highest prevalence occurring among Malawians [29.0% (95%CI = 27.4-30.7)]. Meanwhile, the prevalence of TP among older adolescents (18-19 years) was approximately two-thirds significantly higher compared with young adolescents [aPR(95%CI) = 1.60[1.49-1.71)]. The prevalence of PV among teenagers across the five countries was 24.2% (95%CI = 22.3-26.2). The highest prevalence of PV was recorded among Nigerian adolescent women [31.8% (95%CI = 28.5-35.3)]. The prevalence of PV among adolescent women who were pregnant was approximately 5-folds significant compared to those who were not pregnant (adjusted prevalence ratio; aPR = 4.70; 95% CI: 3.86-5.73; p<0.0001). Conclusion There was a high prevalence of pregnancy among older teenagers aged 18-19 years. Close to a quarter of teenage women ever experienced physical violence. Pregnant teenage women ever experience of physical violence was very high compared to non-pregnant peers. Intervention should target PV and TP by adopting a gender-sensitive approach to eliminate physical violence, particularly among teenagers to prevent TP.
