HIV Rates For Black Women In Parts Of The US Much Higher Than Previously Estimated
Women constitute roughly one-quarter of new HIV infections in the US with 66 percent of these infections occurring among black women, although black women constitute only 14 percent of the US female population. In the US, the age-adjusted death rate of black women with HIV is roughly 15 times higher than that observed for HIV-infected white women.
"Despite prevention efforts in the last 30 years, the reality is that we still have ongoing HIV transmission in the US that requires focusing prevention efforts," said Hodder.
HPTN 064 (ISIS) Study Background:
The HPTN 064 (ISIS) study, funded by the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institute of Health, enrolled a total of 2,099 women, ages 18 to 44 years, between May 2009 and July 2010. Eighty-eight percent of women were black, 12% Hispanic/Latina. Women were enrolled from 10 communities in six distinct geographical areas in the northeast and southeast regions of the US; Atlanta, GA, Raleigh-Durham, NC, Washington D.C., Baltimore, MD, Newark, NJ, New York City, NY.
The study used a novel approach to recruit participants, focusing on geographic areas of the US with the highest HIV prevalence rates in women, i.e. 'hot spots'. Women without a prior positive HIV test living in areas with high HIV prevalence and poverty were eligible for enrollment and were interviewed about many key aspects of their lives including mental health, sexual behavior, history of sexually transmitted infections (STIs), domestic violence, social support, financial insecurity and health care utilization.
Another significant finding from the study is the high number of women who were found to have HIV infection at the time of enrollment (32 women or 1.5%). These women were previously unaware of their HIV status. This finding highlights the need to increase awareness of HIV risk and expand novel HIV testing and prevention efforts in high prevalence areas of the US.
"The study provides convincing evidence that more effort is needed to develop effective prevention strategies for high risk populations in order to stem the HIV epidemic in the US," said Sten Vermund from Vanderbilt University, Principal Investigator of the HPTN.
