PROBLEM: Does child abuse increase the likelihood of HIV infection and subsequent disease mismanagement?

METHODOLOGY: Duke University researchers led by Brian Pence monitored more than 600 HIV-positive patients, aged 20 to 71, in the "Coping with HIV/AIDS in the Southeast" study. They investigated possible links to traumatic experiences, HIV-related behaviors, and health outcomes.

RESULTS: A quarter of the respondents were sexually abused as children. Moreover, half of the patients had faced three or more traumatic experiences in their lifetime, including enduring physical abuse and witnessing domestic violence as a child, living through a parent's suicide attempt or completion, or losing a child.

These painful experiences predicted worse health-related behaviors, such as instances of unprotected sex, missed antiretroviral medications, recent emergency room visits, and hospitalizations. Those who lived through such ordeals were also more likely to die or see their health decline during the two-year study period.
