Behavioral and Clinical Characteristics of Self-Identified Bisexual Men Living with HIV Receiving Medical Care in the United States-Medical Monitoring Project, 2009-2013.

Nationally representative data comparing demographic, risk, and clinical information among bisexual men with other MSM or heterosexuals are lacking. We described differences in demographic characteristics, behaviors, and clinical outcomes among self-identified HIV-positive bisexual, gay, and heterosexual men receiving HIV medical care in the United States. We analyzed data from the 2009-2013 cycles of the Medical Monitoring Project (MMP), a surveillance system that provides nationally representative estimates of behavioral and clinical characteristics of adults with diagnosed HIV in medical care. Altogether, 10% (95% confidence interval [CI] 9-11) of men self-identified as bisexual, 56% (CI 51-61) as gay, and 32% (CI 28-37) as heterosexual. We observed significant differences in demographic factors, clinical outcomes, drug use, and sexual behavior among bisexual men compared with gay and heterosexual men. Providers should consider sexual identities as well as sexual behaviors when developing and implementing prevention programs.
