CDC Estimates HIV Prevalence in U.S. Adults From '07 to '12

Prevalence estimated at 0.39 percent; 51.9 percent of HIV-infected on antiretroviral tx

THURSDAY, Sept. 24, 2015 (HealthDay News) -- The estimated prevalence of HIV is 0.39 percent among U.S adults, according to a study published online Sept. 24 in the National Health Statistics Reports published by the U.S. Centers for Disease Control and Prevention.

Joseph Woodring, D.O., M.P.H., from the CDC in Hyattsville, Md., and colleagues used data from the 2007 to 2012 National Health and Nutrition Examination Surveys to estimate HIV prevalence, the correlation of HIV status with key risk factors, and prevalence of antiretroviral drug use among HIV-infected adults.

The researchers found that overall HIV prevalence among adults aged 18 to 59 years was 0.39 percent during 2007 to 2012. HIV-infection was more likely for men than women and for non-Hispanic blacks compared with all other race and Hispanic origin subgroups combined. High-risk populations, including those with herpes simplex virus type 2 infection, 10 or more lifetime sexual partners, history of sexually transmitted infection, and history of same-sex sexual contact among men, were associated with HIV infection. Overall, 51.9 percent of HIV-infected adults were on antiretroviral therapy; 86.1 percent of HIV-infected adults reported any lifetime history of HIV testing outside of blood donations.

"This report presents the most recent estimates on HIV prevalence in the United States, the association of HIV status with key risk factors, and the prevalence of antiretroviral drug use among HIV-infected adults," the authors write.
