Note: n = 1638. For sub‐group analyses, we report Wald test p‐values for the interaction term. Multivariable models adjust for participant characteristics: HIV status; age; relationship status; parental monitoring; rural/urban household location; informal housing type; number of people living in household; maternal orphanhood; paternal orphanhood; and food security. Clustering of multiple outcomes within individuals is accounted for using the GEE method.

Abbreviations: AGYW, adolescent girls and young women; AOR, adjusted odds ratio; CI, confidence interval; HIV, human immunodeficiency virus.
