(HealthDay News) — The estimated prevalence of HIV is 0.39% among U.S adults, according to a study published online September 24 in the National Health Statistics Reports published by the U.S. Centers for Disease Control and Prevention.
Joseph Woodring, DO, MPH, from the CDC in Hyattsville, MD, and colleagues used data from the 2007–2012 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 18–59 years was 0.39% during 2007–2012. 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% of HIV-infected adults were on antiretroviral therapy; 86.1% 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.
