Correlates of hepatitis B virus and HIV knowledge among gay and bisexual homeless young adults in Hollywood.

Homeless gay and bisexual (G/B) young men have multiple risk factors that increase their risk of contracting hepatitis B virus (HBV) and human immunodeficiency virus (HIV). This study used baseline information from structured instruments to assess correlates of knowledge to HIV and HBV infection from 267 young (18-39 year old) G/B active methamphetamine, cocaine, and crack-using homeless men enrolled in a longitudinal trial. The study is designed to reduce drug use and improve knowledge of hepatitis and HIV/AIDS in a community center in Hollywood, California.
