Bottom Line: For men in Rakai it has decreased slightly over time but increased in Kisesa and Masaka.The age-specific proportion of married individuals has changed little over time.Median AFS, AFM and time spent single vary considerably among these populations.

ABSTRACT

Objectives: To describe trends in age at first sex (AFS), age at first marriage (AFM) and time spent single between events and to compare age-specific trends in marital status in six cohort studies.

Methods: Cohort data from Uganda, Tanzania, South Africa, Zimbabwe and Malawi and Demographic and Health Survey (DHS) data from Uganda, Tanzania and Zimbabwe were analysed. Life table methods were used to calculate median AFS, AFM and time spent single. In each study, two surveys were chosen to compare marital status by age and identify changes over time.

Results: Median AFM was much higher in South Africa than in the other sites. Between the other populations there were considerable differences in median AFS and AFM (AFS 17-19 years for men and 16-19 years for women, AFM 21-24 years and 18-19 years, respectively, for the 1970-9 birth cohort). In all surveys, men reported a longer time spent single than women (median 4-7 years for men and 0-2 years for women). Median years spent single for women has increased, apart from in Manicaland. For men in Rakai it has decreased slightly over time but increased in Kisesa and Masaka. The DHS data showed similar trends to those in the cohort data. The age-specific proportion of married individuals has changed little over time.

Conclusions: Median AFS, AFM and time spent single vary considerably among these populations. These three measures are underlying determinants of sexual risk and HIV infection, and they may partially explain the variation in HIV prevalence levels between these populations.

U9G-85-S1-0064-f04: Median years spent single and sexually active by sex, country and 10-year birth cohort using Demographic and Health Survey (DHS) data.

Mentions: For women in Rakai and Manicaland, the median number of years spent single was the same as those obtained from the DHS for Uganda and Zimbabwe, respectively (fig 4). The Tanzanian and Ugandan DHS indicated a shorter median time spent single than that observed for the cohort studies in Kisesa and Masaka. The median number of years that women in the 1970–9 cohort spent single (2 years) was 1 year longer in Kisesa than the DHS reported for Tanzania (1 year (95% CI 0.84 to 1.17)) and 2.5 times longer (2.5 years) in Masaka than reported in the Uganda DHS (1 year (95% CI 0.69 to 1.33)). Many more women in these DHS reported AFS to be the same as AFM than in the cohort surveys.
