ObjectivesTo identify risk factors for hepatitis C among HIV-positive men who have sex with men (MSM), focusing on potential sexual, nosocomial, and other non-sexual determinants.BackgroundOutbreaks of hepatitis C virus (HCV) infections among HIV-positive MSM have been reported by clinicians in post-industrialized countries since 2000. The sexual acquisition of HCV by gay men who are HIV positive is not, however, fully understood.MethodsBetween 2006 and 2008, a case-control study was embedded into a behavioural survey of MSM in Germany. Cases were HIV-positive and acutely HCV-co-infected, with no history of injection drug use. HIV-positive MSM without known HCV infection, matched for age group, served as controls. The HCV-serostatus of controls was assessed by serological testing of dried blood specimens. Univariable and multivariable regression analyses were used to identify factors independently associated with HCV-co-infection.Results34 cases and 67 controls were included. Sex-associated rectal bleeding, receptive fisting and snorting cocaine/amphetamines, combined with group sex, were independently associated with case status. Among cases, surgical interventions overlapped with sex-associated rectal bleeding.ConclusionsSexual practices leading to rectal bleeding, and snorting drugs in settings of increased HCV-prevalence are risk factors for acute hepatitis C. We suggest that sharing snorting equipment as well as sharing sexual partners might be modes of sexual transmission. Condoms and gloves may not provide adequate protection if they are contaminated with blood. Public health interventions for HIV-positive gay men should address the role of blood in sexual risk behaviour. Further research is needed into the interplay of proctosurgery and sex-associated rectal bleeding.
Internalised homonegativity refers to a gay person's negative feelings about homosexuality and is believed to stem from negative societal stereotypes and attitudes towards homosexuality. Surprisingly, little research has centred on this link. In this research, we aimed to examine the associations between internalised homonegativity and structural forces, cultural influence, and access to sexual health promotion measures among a sample of 144,177 men who have sex with men (MSM) in 38 European countries. Participants were recruited as part of the European MSM Internet Survey (EMIS) during 2010. It was a self-completion, multilingual Internet-based survey for men living in Europe who have sex with men and/or feel attracted to men. Assumed causal relations were tested through multiple regression models. Variables at the structure of rule-systems (macro-level) that were significantly and negatively associated with internalised homonegativity were the presence of laws recognising same-sex relationships and same-sex adoption. In the meso-level model, greater proportions of the population expressing that they would not like to have homosexuals as neighbours predicted higher internalised homonegativity. In the last model, five variables were significantly and negatively associated with internalised homonegativity: being exposed to HIV/STI information for MSM, access to HIV testing, access to STI testing, access to condoms, and experience of gay-related hostility. In turn, men who had tested for HIV in the past year evidenced lower internalised homonegativity. This is the largest and certainly most geographically diverse study to date to examine structural and environmental predictors of internalised homonegativity among MSM. Our results show that one insidious consequence of society's stigma towards homosexuals is the internalisation of that stigma by gay and bisexual men themselves, thus, drawing attention to the importance of promoting social equity for self-acceptance around gay identity in building a positive sense of self.
Objective Substantial country-level variation exists in prejudiced attitudes towards male homosexuality and in the extent to which countries promote the unequal treatment of MSM through discriminatory laws. The impact and underlying mechanisms of country-level stigma on odds of diagnosed HIV, sexual opportunities, and experience of HIV-prevention services, needs and behaviours have rarely been examined, however. Design Data come from the European MSM Internet Survey (EMIS), which was administered between June and August 2010 across 38 European countries (N =174 209). Methods Country-level stigma was assessed using a combination of national laws and policies affecting sexual minorities and a measure of attitudes held by the citizens of each country. We also assessed concealment, HIV status, number of past 12-month male sex partners, and eight HIV-preventive services, knowledge, and behavioural outcomes. Results MSM living in countries with higher levels of stigma had reduced odds of diagnosed HIV and fewer partners but higher odds of sexual risk behaviour, unmet prevention needs, not using testing services, and not discussing their sexuality in testing services. Sexual orientation concealment mediated associations between country-level stigma and these outcomes. Conclusion Country-level stigma may have historically limited HIV transmission opportunities among MSM, but by restricting MSM’s public visibility, it also reduces MSM’s ability to access HIV-preventive services, knowledge and precautionary behaviours. These findings suggest that MSM in European countries with high levels of stigma are vulnerable to HIV infection. Although they have less opportunity to identify and contact other MSM, this might change with emerging technologies.
