Transactional sex is associated with incident HIV infection among adolescent girls and young women (AGYW) in sub-Saharan Africa. Evidence on the dimensions of socioeconomic status (SES) which predict transactional sex are mixed and primarily come from cross-sectional studies. This study examined the association between SES and transactional sex in a longitudinal cohort (n = 844) of AGYW ages 15-24 years enrolled in a quasi-experimental study in Lilongwe, Malawi. Prevalence of transactional sex was 22% at baseline, 15% at 6-months and 20% at 12-months. Being divorced or widowed, being food insecure, living in a home without electricity or running water, and having few assets were associated with transactional sex. Higher educational attainment and school enrollment were protective. Having 6-7 socioeconomic risk factors increased odds of transactional sex (AOR = 4.13, 95% CI 2.45, 6.98). Structural interventions which address multiple dimensions of SES may reduce transactional sex and ultimately prevent HIV transmission among AGYW.

马拉维青春期女孩和年轻女性队列中性交易的社会经济预测因素：纵向分析。

性交易与撒哈拉以南非洲少女和年轻妇女的艾滋病毒感染相关。预测交易性行为的社会经济地位（SES）维度的证据不一，主要来自横断面研究。这项研究在马拉维利隆圭的一项准实验研究中，对15-24岁的AGYW的纵向队列（n = 844）中的SES与交易性之间的关联进行了研究。交易性行为的患病率在基线时为22％，在6个月时为15％，在12个月时为20％。离婚或丧偶，粮食不安全，住在没有电或自来水的家庭中，资产很少，都与性交易有关。高等教育程度和入学率是保护性的。有6-7个社会经济风险因素会增加性交的几率（AOR = 4.13，95％CI 2.45，6.98）。解决SES多个方面的结构性干预措施可以减少性交易，并最终防止HIV在AGYW之间传播。
