- Brief, Clinic-Based, Peer-led Intervention Helps Reduce Subsequent STDs in African American Men
- Science Update June 18, 2009
A brief, one-time intervention delivered by a trained peer health advisor was an effective and low-cost method for reducing new infections among young, heterosexual, African American men diagnosed with a sexually transmitted disease (STD), according to an NIMH-funded study. Such programs may help reduce STD-related health disparities, which currently affect a disproportionate number of African American men in the United States. The study was published in the April 2009 supplemental issue of the American Journal of Public Health.
- HIV Prevention Program Gets a Boost From NIMH Recovery Act Funds
- Press Release May 26, 2009
Developing interventions to reduce the spread of HIV and other sexually transmitted infections among heterosexual men, couples and ethnically diverse populations continues to be complex and challenging. To help address this issue, NIMH awarded a two-year grant to David Pérez-Jiménez, Ph.D., at the University of Puerto Rico, to support the adaptation and assessment of an HIV and other sexually transmitted infection intervention designed for young, heterosexual Latino couples. This grant will use funds allocated to NIMH through the American Recovery and Reinvestment Act to promote economic recovery and spur advances in science and health.
- Child Abuse Survivors Have Higher Risk for STDs in Adulthood Than Non-abused Adults
