Syndemic factors and HIV infection among men who have sex with men in Taiwan.

We tested the applicability of syndemic theory to men who have sex with men (MSM) in Taiwan. Of 200 MSM (mean age = 27.1 years) surveyed, the majority (54%) experienced at least one syndemic burden due to problem drug use, intimate partner violence, or HIV stigma. In multivariable analysis, MSM with one or more syndemic burdens had greater than threefold higher odds of being HIV-positive. The impact of co-occurring psychosocial health conditions on HIV infection among MSM in Taiwan indicates the importance of identifying and engaging HIV-positive MSM in effective treatment, and implementing interventions more broadly to decrease syndemic burden.
