Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This study examined the timing of first sexual experience among 5,833 young women aged 15-24 in Zambia using nationally representative survey data from 2024. The median age at first sexual experience was 17 years, with 70% of young women having experienced sex before age 25. Being older (20-24 years), from a wealthier household, and being literate were all associated with delaying first sexual experience. The findings suggest that education and reducing socioeconomic inequality are important for interventions aimed at delaying sexual initiation.
Key points
- 70% of young women (95% CI: 0.71-0.73) had their first sexual experience before age 25
- Median age at first sexual experience was 17 years
- Being aged 20-24 years was associated with lower hazards of earlier sexual experience (AHR = 0.75)
- Coming from a rich household reduced hazards of earlier sexual experience (AHR = 0.75)
- Literacy was associated with delayed sexual initiation (AHR = 0.87)
Limitations
This is a cross-sectional analysis of survey data that measures association rather than causation; the study cannot determine whether education and wealth actually cause delayed sexual initiation or whether other unmeasured factors explain these associations. Additionally, data rely on self-report and may be subject to recall bias or social desirability bias.
Abstract
Early sexual experience among young women increases the risk of unintended pregnancies, sexually transmitted infections, and adverse psychosocial and health outcomes. Examining the timing to first sexual experience is very vital in informing sexual and reproductive health policies and interventions aimed at reducing the health risks among young women. However, there is limited recent evidence in Zambia, particularly studies utilizing nationally representative data such as the 2024 Zambia Demographic and Health Survey. Therefore, the study aimed to investigate the determinants of time to first sexual experience among young women in Zambia. Secondary data from the Zambia Demographic and Health Survey (ZDHS 2024) was used in the study. A weighted sample of 5,833 young women was considered in the study. Kaplan-Meier curve, log-rank test, and Cox proportional hazards regression were used to establish the median age at first sexual experience and identify determinants of time to first sexual experience, with statistical significance set at p < 0.05. The study found that 70% (95% CI: 0.71 - 0.73) of the young women had their first sexual experience before the age of 25. The overal median age to first sexual experience was 17 years. Multivariable Cox regression results showed that lower hazards of earlier sexual experience were associated with being aged 20-24 years (AHR = 0.75, 95% CI: 0.70-0.80), coming from a rich household (AHR = 0.75, 95% CI: 0.67-0.85), and being literate (AHR = 0.87, 95% CI: 0.80-0.94). The findings show that age, household wealth, and literacy are significant factors associated with the timing of first sexual experience among young women in Zambia. Interventions to delay sexual initiation should focus on improving girls' education and addressing socioeconomic inequalities.
