Factors associated with testing for hepatitis C in an Internet-recruited sample of men who have sex with men

Background: Nearly 4 million individuals in the United States (1.8%) have b een infected with hepatitis C virus, yet few are aware of their infection. Goal: To identify correlates associated with hepatitis C virus testing amon g a sample of men who have sex with men. Study Design: Internet communicati ons were used for solicitation and collection of data, using a 31-question survey. Results: When the study was restricted to men who have sex with men in the United States (n = 381), 95% of the respondents (n = 361) reported at least one risk factor for hepatitis C virus transmission, 39% of these responden ts (n = 140) reported having been tested for hepatitis C virus. Testing was associated with a history of nonsexual risk behavior, increased knowledge of the hepatitis C virus, and healthcare provider communication. Conclusion: A significant proportion of at-risk respondents had not been te sted. Interventions are needed to increase hepatitis C virus knowledge in t he community of men who have sex with men, and to encourage providers to co mmunicate about hepatitis to the men in this group who screen as high risk on the basis of their risk behaviors.
