ABSTRACT
HIV self-testing (HIVST) can improve testing completion among adolescents and young adults (AYA), although its influence on sexual behaviors is unclear. We evaluated whether HIVST was associated with changes in talking with sexual partners about HIVST, condom use, and HIV risk perception among AYA ages 15-24 years in a study of HIVST distribution through homes, pharmacies, and nightclubs in Nairobi, Kenya. All participants had negative HIVST results. Regression models were used to evaluate changes between pre-HIVST and 4 months post-HIVST. Overall, there was a significant increase in talking with sexual partners about HIVST. There was a significant reduction in number of condomless sex acts among AYA recruited through pharmacies and homes. Unexpectedly, among females, there was a significant decrease in consistent condom use with casual partners. HIVST services for AYA may benefit from including strategies to support condom use and partner communication about self-testing adapted to specific populations and partnerships.
