Epidemiology of HIV-1 infection in rural Georgia: demographic trends and analysis at the Medical College of Georgia.
We have conducted a retrospective study of 100 HIV-infected patients enrolled in an AZT monotherapy clinical study at the Medical College of Georgia (MCG) in Augusta, Georgia. When compared to the national trends, our results confirm previous studies that describe an overall increase in the burden of HIV infections among blacks, and, in particular, black women in the rural Southeast. In our cohort, infections due to homosexual contact accounted for approximately 40% of all cases while heterosexual contact and intravenous drug use (IDU) comprised 33% and 13%, respectively. Infections attributable to all other risk factors accounted for the remaining 14%. Relative to national surveillance data, we observed an increase in the prevalence of HIV infections among blacks, and heterosexually acquired infections, particularly among black women. Our analysis illustrates the dynamic nature of the current U.S. epidemic which appears to be shifting both in terms of its demographic and epidemiological profile. These data may indicate that national surveillance data may not reflect the dynamic nature of current demographic trends in HIV incidence, particularly as evidenced in the rural Southeast. This suggests that hospital or laboratory based cross-sectional studies, like ours, that analyze demographic variables of HIV-infected clinic attendees may be necessary to more accurately assess the leading edge of the HIV epidemic in rural, non-metropolitan areas.
