title: A comparison of hepatitis A and hepatitis B measures among vaccinated and susceptible online men who have sex with men.
abstract: Hepatitis A virus (HAV) and hepatitis B virus (HBV) continue to be major health concerns among men who have sex with men (MSM). The Internet both facilitates high-risk sexual encounters and provides opportunities for promoting healthy behaviours. This study compared self-reported HAV and HBV vaccination levels, based on demographics, health characteristics, hepatitis knowledge, attitudes and risk behaviours among MSM using an online survey posted from February through June 2005. Each participant (n = 968) reported whether they were vaccinated, infected or susceptible for hepatitis A and/or for hepatitis B. Men whose health-care provider recommended vaccination were 12.91 (95% confidence interval [CI] 8.11, 20.55) times more likely to be vaccinated against HAV and 17.93 (95% CI 10.82, 29.70) times more likely to be vaccinated against HBV than those at risk of infection, respectively. These data provide essential information for public health professionals to successfully promote vaccination among members of this population.
