In recent years, there have been increases in the rates of unprotected anal intercourse (UAI) reported by men who have sex with men (MSM) and in the numbers of newly diagnosed HIV infections among MSM. Surveys of young MSM (ages 15-29) in numerous U.S. cities from 1994-2000 found an HIV prevalence of 2.2% to 18%, however, HIV prevalence was higher among young MSM of color than among white men. In a survey of 23-29 year-old MSM,nearly 1/3 of African-American men and 15% of Hispanic/Latino men were infected with HIV.
