Sociodemographic, sexual, and HIV and other sexually transmitted disease risk profiles of nonhomosexual-identified men who have sex with men.

I examined sociodemographic, sexual, and HIV and other sexually transmitted disease risk differences among homosexual- and nonhomosexual-identified men who have sex with men (MSM) in the United States. Non-Mexican Latino ethnicity, marriage or cohabitation, religiosity, and incarceration history were positively associated with being nonhomosexual identified. Being nonhomosexual identified was associated with some risk (e.g., more sexual intercourse while intoxicated) and protective (e.g., fewer male partners) behaviors. Probabilistic sampling strategies may be useful in future research and intervention efforts.
