Pregnancy risk behaviour among sexually active adolescent girls aged 10-17 years in high HIV prevalence districts in Uganda: a cross-sectional secondary analysis of the 2018 AGYW survey data.
Introduction: Although global adolescent birth rates steadily declined over the past decade, they remain persistently high within the African region. However, there is limited evidence on why they remain high. We estimated the prevalence of pregnancy risk behaviour and associated factors among sexually active adolescent girls (AG) aged 10-17 years in high HIV prevalence districts in Uganda.
Methods: This was a secondary analysis of data collected as part of a large cross-sectional study conducted among AGs and young women (AGYW) aged 10-24 years in July 2018. This analysis focused on AGs aged 10-17 years reporting sexual intercourse in the past 12 months. The primary outcome was prevalence of pregnancy risk behaviour, defined as engaging in sex without using pregnancy protection or using ineffective pregnancy prevention methods. Descriptive analysis and modified multivariable Poisson regression were used to determine the prevalence and factors associated. Statistical significance was set at p<0.05. Analyses were performed using Stata V.16.
Results: Of the 8236 AGYW enrolled into the large study, 53.6% (n=4414) had ever had sex. Of these, 80.6% (n=3560) had sex in the past year, of whom 9% (n=323) were AGs aged 10-17 years. Two-thirds of the 10-17 years old (66.3%, n=214) were out-of-school. Of 323 AGs, 63.8% (95% CI: 58.5% to 69.0) engaged in pregnancy risk behaviour in the past year. Being Anglican (adjusted prevalence ratio (aPR)=1.28; 95% CI: 1.01 to 1.61) and having two or more sexual partners in the past year (aPR=1.20; 95% CI: 1.02 to 1.43) increased the likelihood of engaging in pregnancy risk behaviour while having secondary or higher education was protective (aPR=0.67; 95% CI: 0.45 to 0.98).
Conclusion: 6 in 10 AGs aged 10-17 years engaged in pregnancy risk behaviour. Findings suggest that attaining higher levels of education is beneficial against pregnancy risk behaviour and underscore the need of keeping girls in school longer.
