Objectives: To describe changes in AIDS incidence for men who have sex with men (MSM) from 1990 to 1995, by demographic and geographic groups.
Methods: We examined national AIDS surveillance data reported up to 30 September 1996, for men who received AIDS diagnoses in the years 1990-1995 and whose only reported risk behavior was sex with men. We evaluated trends in AIDS rates by estimating the incidence of clinical AIDS (AIDS defined by opportunistic illnesses), and report clinical AIDS incidence rates for MSM (AIDS rates) and proportional change in rates from 1990 to 1995.
Results: Clinical AIDS rates (MSM per 100,000 men per year) increased by 12% from 25.5% in 1990 to 28.5% in 1995. Significant variations in AIDS rates and 5-year changes in AIDS rates were observed in various subgroups of MSM. Five-year increases in AIDS rates were highest for American-Indian/Alaskan native (53%), black (45%), and Hispanic (23%) MSM; the only decrease occurred for white MSM (-2%). Incidence for black MSM increased from twofold (in 1990) to threefold (in 1995) the rate for white MSM. Large increases in AIDS rates were observed for MSM in rural areas (34%) and areas with 50,000 to 249,999 residents (34%) and for MSM aged over 60 years (32%).
Conclusions: The high national AIDS rate for MSM continued to rise, but more slowly than earlier in the epidemic. Racial/ethnic minority MSM had consistently large increases in AIDS rates; AIDS rates decreased only slightly for white MSM. The AIDS epidemic among MSM is not homogenous, and AIDS rates continue to increase for minority MSM, and MSM living in rural areas. HIV prevention remains a high priority for all MSM, especially black and Hispanic MSM.
