HIV behavioral interventions can cut high-risk sexual behaviors in half and more than double the regular use of condoms, according to researchers at the Johns Hopkins School of Public Health. The School was one of seven sites across the country participating in the National Institute of Mental Health (NIMH) Multi-site HIV Prevention Trial, a new study of behaviors in mostly low-income women and men served in public health care clinics. The study was published in the June 19, 1998, issue of Science.
Site principal investigator David D. Celentano, ScD, professor, Epidemiology, Johns Hopkins School of Public Health, said, "This study is significant to public health because it identifies a successful strategy to reduce high-risk behaviors and prevent new HIV infections."
The largest, randomized, controlled HIV behavioral intervention study ever conducted in the United States, the study enrolled 3,706 men and women in 37 inner-city, community-based clinics.
Those attending HIV prevention sessions designed to teach ways to reduce high-risk sexual behaviors reported significant reductions across a range of sexual risk indicators over a one-year period. The more intervention sessions the participants attended, the less high-risk behaviors they engaged in.
Among men who took the seven-session intervention, for instance, the incidence of gonorrhea fell by half. Gonorrhea is an important indicator of unprotected sexual behavior and a leading sexual risk factor for HIV infections among heterosexuals.
Researchers at seven sites in five metropolitan areas recruited
participants from three distinct populations at risk of acquiring HIV and other
STDs: men and women in public STD clinics, and women attending public primary
health care clinics. Seventy-four percent of participants were African American
and 25 percent were Hispanic; most were single and unemployed and had been
treated previously for STD
