Background: Hepatitis A outbreaks are well documented among men who have sex with men (MSM). This analysis examines characteristics associated with hepatitis A virus (HAV) infection among a large group of young adult MSM from five USA cities.
Methods: The Young Men's Survey was a cross-sectional prevalence study of HIV infection and related behavioural risk factors among MSM aged 15-29 years during 1994-2000.
Objectives: We measured the prevalence of hepatitis B virus (HBV) immunization and HBV infection among men aged 23 to 29 years who have sex with men.
Methods: We analyzed data from 2834 men who have sex with men in 6 US metropolitan areas. Participants were interviewed and tested for serologic markers of immunization and HBV infection in 1998 through 2000.
Objectives: We sought to characterize substance use patterns in young men who have sex with men (MSM) in 7 US urban areas and sociodemographic characteristics and history associated with such use.
Methods: We examined data collected from 1994 through 1998 in a venue-based, cross-sectional survey.
Results: Among the 3492 participants, 66% reported use of illicit drugs; 28%, use of 3 or more drugs; 29%, frequent drug use (once a week or more); and 4%, injection drug use.
