Sexual behavior changes and HIV antibody in a cohort of New York City gay men.

Abstract
A sample of 357 gay/bisexual men, ages 20 to 65, were interviewed in 1985 regarding their sexual patterns over the course of the AIDS (acquired immunodeficiency syndrome) epidemic. Within four months after the interview, men were tested for antibody to HIV (human immunodeficiency virus) and 36 per cent were found positive. Cessation of receptive anal intercourse was associated with HIV negative antibody status, (OR greater than 3.0). Reducing the number of sexual partners, becoming monogamous, or eliminating other forms of sexual contact were not related to risk of HIV.
