The African Youth Alliance (AYA) was a partnership to improve adolescent sexual and reproductive health, and prevent HIV/AIDS in Botswana, Ghana, Tanzania and Uganda. The AYA model was a comprehensive range of integrated interventions, implemented concurrently and at scale using a multi-sectoral approach. AYA was funded for five years (2000-2005) with $56.7 million from the Bill and Melinda Gates Foundation. Over 35,000,000 stakeholders were reached through media campaigns, almost 400,000 young people received Life Planning Skills training, and over 2,500,000 visits were made by young people to static clinics and outreach services. A post-test evaluation was conducted by John Snow Inc. (JSI) in 2006 and combined case-control and self-reported exposure design. Case-control design data were analyzed using Propensity Score Matching (PSM), and the Self-Reported Exposure design data were analyzed using PSM and Instrumental Variable (two-stage regression) (IV). The results show AYA's significant and positive treatment effects on sexual knowledge, attitudes, and behaviours. The research suggests a comprehensive, multi-component approach such as AYA's can be effective in improving some key ASRH variables.
非洲青年联盟（AYA）是一个旨在改善博茨瓦纳、加纳、坦桑尼亚和乌干达青少年性健康和生殖健康，并预防艾滋病毒/艾滋病的合作伙伴关系。AYA模式是一系列全面的综合干预措施，采用多部门方法同时大规模实施。AYA在2000年至2005年的五年间获得了比尔及梅琳达·盖茨基金会提供的5670万美元资金。通过媒体宣传活动，超过3500万利益相关者受到影响，近40万年轻人接受了生活规划技能培训，超过250万年轻人前往固定诊所和外展服务机构就诊。2006年，约翰·斯诺公司（JSI）进行了一项事后评估，采用了病例对照和自我报告暴露设计相结合的方法。病例对照设计数据使用倾向得分匹配（PSM）进行分析，自我报告暴露设计数据使用PSM和工具变量（两阶段回归）（IV）进行分析。结果显示AYA对性知识、态度和行为产生了显著的积极治疗效果。该研究表明，像AYA这样的全面、多组成部分的方法在改善一些关键的性健康和生殖健康变量方面可能是有效的。
