Objective: To examine factors associated with hepatitis B virus (HBV) vaccination status, including knowledge and attitudes about hepatitis and vaccination, and sexual and non-sexual risk behaviors among men who have sex with men (MSM). Methods: For one month, we surveyed MSM using the internet. We solicited owners and webmasters to link from their gay- or bisexually-themed web sites to our survey; we posted notices in guest books of gay- or bisexually-themed web sites; and, we sent mass emails through MSM-serving listservs. Results: Of 628 responses, 79.2% were male, and 90.3% were from the United States. In total, 18 countries were represented. When restricted to MSM from the United States, respondent average age was 37.6 years. 42% reported at least one dose of the HBV vaccination, whereas 58% reported being unvaccinated. 21% reported receiving no information about hepatitis. 72% of respondents reported never using condoms during oral intercourse; 26% reported using condoms less than half of the time during anal intercourse. Using logistic regression modeling, lack of vaccination was associated with increased age. Variables predictive of vaccination were higher HBV vaccination knowledge, discussion with physician about hepatitis, and professional training that included hepatitis education. Conclusion: A significant proportion of respondents, some of whom were at risk for contracting HBV, was unvaccinated. Our findings underscore the need for health-care providers to inform patients about the efficacy and safety of the vaccine and encourage vaccination, particularly among MSM who screen as high risk based on their sexual or drug use behaviors.
