Drought, HIV Testing, and HIV Transmission Risk Behaviors: A Population-Based Study in 10 High HIV Prevalence Countries in Sub-Saharan Africa

pmid: 36066761
Droughts are associated with poor health outcomes and disruption of public health programming. Data on the association between drought and HIV testing and transmission risk behaviors are limited. We combined data from Demographic and Health Surveys from 10 high HIV prevalence sub-Saharan African countries with a high-resolution measure of drought. We estimated the association between drought and recent HIV testing, report of condomless sex, and number of sexual partners in the last year. Respondents exposed to drought were less likely to have an HIV test and more likely to have condomless sex, although effect sizes were small. We found evidence for effect modification by sex and age for the association between drought and HIV testing, such that the negative association between drought and HIV testing was strongest among men (marginal risk ratio [mRR] 0.92, 95% CI 0.89-0.95) and adolescents (mRR 0.90, 95% CI 0.86-0.93). Drought may hinder HIV testing programs in countries with high HIV prevalence.
