Using a randomized controlled trial in rural eastern Zimbabwe, we tested whether comprehensive support to keep orphan adolescent girls in school could reduce HIV risk.
All orphan girls in grade 6 in 25 primary schools were invited to participate in the study in fall 2007 (n = 329). Primary schools were randomized to condition. All primary schools received a universal daily feeding program; intervention participants received fees, uniforms, and a school-based helper to monitor attendance and resolve problems. We conducted annual surveys and collected additional information on school dropout, marriage, and pregnancy rates. We analyzed data using generalized estimating equations over 3 time points, controlling for school and age at baseline.
The intervention reduced school dropout by 82% and marriage by 63% after 2 years. Compared with control participants, the intervention group reported greater school bonding, better future expectations, more equitable gender attitudes, and more concerns about the consequences of sex.
We found promising evidence that comprehensive school support may reduce HIV risk for orphan girls. Further study, including assessment of dose response, cost benefit, and HIV and herpes simplex virus 2 biomarker measurement, is warranted.
我们在津巴布韦东部农村地区开展了一项随机对照试验,旨在检验全面支持使孤儿少女继续接受教育能否降低艾滋病毒感染风险。
2007 年秋季,邀请 25 所小学六年级的所有孤儿少女参加研究(n=329)。对小学进行随机分组。所有小学都实施普及性每日供餐方案;干预组的参与者还获得学费、校服和一名学校助手,以监督出勤率并解决问题。我们每年开展调查,并收集辍学率、结婚率和怀孕率的额外信息。我们采用广义估计方程,在 3 个时间点进行分析,在校和入学年龄方面进行了控制。
2 年后,干预减少了 82%的辍学和 63%的早婚。与对照组相比,干预组的学校归属感更强,对未来的期望更高,性别态度更加平等,对性行为后果的担忧也更多。
我们发现有希望的证据表明,全面的学校支持可能降低孤儿少女的艾滋病毒感染风险。需要进一步研究,包括评估剂量反应、成本效益以及艾滋病毒和单纯疱疹病毒 2 生物标志物的测量。
