A cross-sectional human immunodeficiency virus type 1 (HIV-1) serosurvey was conducted between January 1988 and January 1993 at a New York City sexually transmitted disease clinic serving predominantly African-American and Hispanic patients.
Overall, 14% (415/3,069) of participating men reported having sex with men ; among these, only 52 (13%) were classified as « homosexual » (having had sex with men exclusively since 1978).
Most men (87%) who reported having sex with other men also reported having sex with women.
These included 147 (35%) « bisexuals » (sex with more than one man and at least one woman since 1978) and 216 (52%) « heterosexuals » (sex with women since 1978 and sexual contact with men before 1978 or only once thereafter).
Although HIV-1 seroprevalence was highest among « homosexual » men (70%, 95% confidence interval (Cl) 55-81), it was also high among « bisexual » men (35%, 95% Cl 27-43) and « heterosexual » men (17%, 95% Cl 13-23), and was lowest in men who reported having no male sex partners in their lifetime (9%, 95% Cl 7-10).
It is possible that transmission of HIV-1 from bisexual men to female sexual partners plays a greater role in heterosexual transmission than was previously recognized.
