Does timing of sexual debut following menarche among female youth in Uganda matter? A discrete time analysis.

ABSTRACT

BACKGROUND: The burden of early sexual engagement among youth is enormous. It directly raises the risk of sexually transmitted infections(STIs) and indirectly contributes to unintended pregnancy, unsafe abortion, premature childbirth, and psychosocial issues. The aim of this paper was to estimate the timing of sexual debut and examine the factors influencing the timing of first sexual intercourse following menarche among female youth aged between 15 and 24 in Uganda. METHOD: Self-reported data were extracted from the 2016 Uganda Demographic and Health Survey (UDHS), with a sub-sample of 7964 female youth from the individual woman file. Kaplan-Meier survival curves, decrement life-table analysis, and the discrete-time logit model were used to examine the timing of sexual debut and associated factors. RESULTS: 67.4% of the female youth had experienced first sexual initiation. Overall, the meantime to sexual debut was 4.4 years and the median time was 4.3 years, and all the female youth had experienced first sexual initiation by the end of the twelfth year following menarche. Significant factors found to influence the timing of sexual initiation include having higher education level (OR = 0.724 95% CI = 0.59-0.89; p = 0.003), residing in the Northern region (OR = 0.87795% CI = 0.79-0.97, p = 0.012), being employed (OR = 1.085 95% CI = 1.01-1.16; p = 0.021), and being literate (OR = 1.155; 95% CI = 1.07-1.25; p < 0.001). CONCLUSIONS: These findings are expected to be central in the bid to delay first sexual intercourse. Also they shed light on some of the factors associated with the timing of sexual debut which may be addressed at community level for non-school going youth and in schools, as school based prevention sexual and reproductive health programs. The findings highlight the need for future studies to collect more data to explore further the linkage between time to first debut since menarche and, mass media, religion, type of residence, and wealth index.
