HIV diagnosis is an important step in the HIV cascade of prevention and treatment. However, men who have sex with
men in low- and middle-income countries have limited access to HIV care services. We examined factors associated with
prior HIV testing among men who have sex with men in western Kenya. We recruited 95 men who have sex with men
aged 18 years and older, and who reported at least one sexual contact with a man in the past 6 months; however, this
analysis is restricted to 89 participants who completed questions on HIV testing. Logistic regression model was used to
determine factors associated with HIV testing in the past one year. Results indicate that 23 (26%) had not been tested in
the past 12 months. Bivariate analyses demonstrated that condomless anal sex (odds ratio ¼ 3.29, 95% confidence
interval ¼ 1.18–9.17) and comfort with healthcare providers (odds ratio ¼ 1.15, 95 % CI ¼ 1.05–1.26) were associated
with higher odds of HIV testing in the past 12 months. Experiencing social stigma was associated with lower odds of HIV
testing in the last 12 months (odds ratio ¼ 0.91, 95% confidence interval ¼ 0.84–0.94). In multivariable models, social
stigma remained significantly associated with lower odds of HIV testing in the last 12 months odds ratio ¼ 0.90, 95%
confidence interval ¼ 0.82–0.99) after inclusion of sexual risk and individual level variables. Development of men who
have sex with men–sensitive HIV-testing services, addressing stigma, and training healthcare workers to provide culturally
sensitive services may assist in effectively engaging men who have sex with men in the HIV treatment cascade.
