Abstract
The goal of this study was to examine where people with acquired immune deficiency syndrome (AIDS) in the United States live and the degree to which AIDS is present in rural areas. AIDS cases reported to the Centers for Disease Control and Prevention (CDC) in 1996 were categorized by metropolitan statistical area (MSA) size and compared to the general population. Data were analyzed by region, race/ethnicity and risk exposure; AIDS incidence rates were compared over time by MSA size. Relative to the U.S. population, AIDS cases were disproportionately black (43 percent vs. 11 percent), male (80 percent vs. 48 percent), and from the Northeast (32 percent vs. 20 percent). In all regions, a greater proportion of AIDS cases reside in large MSAs compared with the general population. Risk exposures differ little by MSA size, except in the Northeast. The proportion of people with AIDS who reside in large MSAs exceeds the proportion of the population in those areas, especially when race/ethnicity is considered. AIDS rates have increased in non-MSAs relative to large MSAs, yet do not indicate that the epidemic is increasing rapidly in rural areas. Fewer AIDS cases are reported from smaller communities, yet require medical and social services that may burden the rural health care system.
