To examine the timing and circumstances of first sex among urban female and male youth in Kenya, Nigeria, and Senegal.
Recently 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.
Across 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.
Programs 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.
探讨肯尼亚、尼日利亚和塞内加尔城市青年首次性行为的时间和环境。
利用最近收集的数据,对肯尼亚、尼日利亚和塞内加尔的青年性行为进行了研究。在每个国家,都从多个城市收集了大量具有代表性的女性(年龄在 15-49 岁之间)和男性(年龄在 15-59 岁之间)样本。对年龄在 15-24 岁的青年进行了分析,以了解初次性行为的年龄、首次性行为是否为婚前性行为,以及首次性行为时是否使用现代计划生育方法。采用 Cox 比例风险模型和逻辑回归分析来确定与这些结果相关的因素。
在所有三个国家,报告与非婚姻伴侣发生首次性行为的男性青年比例均高于女性青年。受教育程度较高的青年在每个年龄段发生性行为的可能性较小。在尼日利亚和塞内加尔,贫穷的女青年比富裕的女青年更早地发生首次性行为。在肯尼亚,较富裕的女青年比较贫穷的女青年更有可能发生婚前首次性行为,并且在首次性行为时更有可能使用避孕方法/避孕套。首次性行为年龄较大以及报告首次性行为是婚前性行为的青年,在首次性行为时更有可能使用避孕方法(包括避孕套)。针对每个结果,都发现了并讨论了与城市特定区分有关的情况。
旨在减少城市青年中 HIV 和意外怀孕风险的项目需要进行需求评估,以了解影响每个城市/国家具体背景下首次性行为时间和环境的当地情况。
