Boston’s Fenway Health and the Multicultural AIDS Coalition (MAC) are looking to recruit 330 HIV-positive and -negative black men who have sex with men (MSM) for Project Save Ourselves (SOS), the Boston branch of a new six-city study to find effective ways to combat HIV in the black gay community, Bay Windows reports. The study is also collecting data from black MSM in New York, San Francisco, Los Angeles, Atlanta and Washington, DC.

According to Ben Perkins, director of Project SOS at Fenway, researchers hope to learn how to increase the HIV testing rates among black MSM and how to get those who are positive into care earlier. Also, in an effort to study black MSM sexual networks, researchers will ask the 330 participants to recruit 70 additional participants from their own circles.

In order to spread the word about the study, researchers will attend community events, reach out to community-based agencies and place advertisements in publications such as the Weekly Dig, Bay Windows and the Boston Metro, as well as online.
