摘要

Adolescent girls and young women (AGYW) in Kenya remain at disproportionate risk of HIV acquisition. While individual risk factors are well-documented, fewer studies examine how these factors co-occur in distinct profiles or how such profiles relate to perceived HIV risk and HIV status. We analyzed data from 2,810 AGYW (aged 15–24) reporting ≥ 1 male sex partner in the prior 12 months in the 2018 Kenya Population-based HIV Impact Assessment (KENPHIA). Latent class analysis identified patterns of condom use, transactional sex, alcohol use, partner type, age disparity, and partner HIV status. Associations between class membership, perceived HIV risk, and HIV status were estimated. Three classes emerged: Married without Condoms (55%) was characterized by low condom and alcohol use and cohabitating partners; Dating with Condoms (42%) featured higher condom use, moderate transactional sex, low alcohol use, and similarly aged, non-cohabiting partners; and Older Husband (4%) was defined by higher alcohol use and older cohabitating partners of positive or unknown HIV status. Members of the Older Husband class had much higher odds of HIV positivity compared to the Married without Condoms class (aOR = 83.33, 95% CI 21.74–333.33) and the Dating with Condoms class (aOR = 54.36, 95% CI 18.51–159.58). Despite similarly low HIV prevalence (1%) in the Married without Condoms and Dating with Condoms classes, the latter perceived higher HIV risk. Distinct profiles exist among Kenyan AGYW. Tailored prevention is needed, especially for AGYW with older partners of unknown status, alongside efforts to improve risk recognition across profiles.
