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.
