Timing and circumstances of first sex among female and male youth from select urban areas of Nigeria, Kenya, and Senegal.

purposeTo examine the timing and circumstances of first sex among urban female and male youth in Kenya, Nigeria, and Senegal.

methodsRecently collected data are used to examine youth sexual behaviors in Kenya, Nigeria, and Senegal. In each country, a large, representative sample of women (ages 15-49) and men (ages 15-59) was collected from multiple cities. Data from youth (ages 15-24) are used for the analyses of age at sexual initiation, whether first sex was premarital, and modern family planning use at first sex. Cox proportional hazard models and logistic regression analyses are performed to determine factors associated with these outcomes.

resultsAcross all three countries, a greater percentage of male youth than female youth report initiating sex with a nonmarital partner. More educated youth are less likely to have initiated sex at each age. In Nigeria and Senegal, poor female youth report earlier first sex than wealthier female youth. In Kenya, richer female youth are more likely to have premarital first sex and to use contraception/condom at first sex than their poorer counterparts. Older age at first sex and youth who report that first sex was premarital are significantly more likely to use a method of contraception (including condom) at first sex. City-specific distinctions are found and discussed for each outcome.

conclusionsPrograms seeking to reduce HIV and unintended pregnancy risk among urban youth need to undertake needs assessments to understand the local context that influences the timing and circumstances of first sex in each city/country-specific context.
