This paper addresses how London gay men use the internet to meet sexual partners, or for e-dating. Based on qualitative interviews conducted face-to-face or via the internet, this research develops an account of how information technologies mediate the negotiation of identity and risk in connection with sexual practice. E-dating itself is a bricolage, or heterogeneous DIY practice of internet-based-communication (IBC). A central aspect of IBC is 'filtering' in and out prospective e-dates based on the images and texts used to depict sexual identities. Interpretations and depictions of personal HIV risk management approaches in IBC are framed by the meanings of different identities, such as the stigma associated with being HIV positive. This paper argues for a sexualities perspective in a theory of network society. Further, HIV prevention in e-dating can potentially be addressed by considering the interplay of the HIV prevention imperatives associated with different HIV serostatus identities. There is a case for encouraging more explicit IBC about risk in e-dating and incorporating the expertise of e-daters in prevention activity. There is also a need to rethink traditional conceptions of risk management in HIV prevention to make space for the risk management bricolage of network society. [ABSTRACT FROM AUTHOR]

Objectives: To examine changes in sexual behaviour among London homosexual men between 1998 and 2003 by type and HIV status of partner. Methods: Homosexual men (n = 4264) using London gyms were surveyed annually between 1998 and 2003 (range 498-834 per year). Information was collect&1 on HIV status, unprotected anal intercourse (UAI) in the previous 3 months, and type of partner for UAI. High risk sexual behaviour was defined as UAI with a partner of unknown or discordant HIV status. Results: Between 1998 and 2003, the percentage of men reporting high risk sexual behaviour with a casual partner increased from 6.7% to 16.1 % (adjusted odds ratio (AOR) 1.36 per year, 95% confidence interval (Cl) 1.26 to 1.46, P <0.001 }. There was no significant change in the percentage of men reporting high risk sexual behaviour with a main partner alone (7.8%, 5.6%, p=0.7). These patterns were seen for HIV positive, negative and never tested men alike regardless of age. The percentage of HIV positive men reporting UAI with a casual partner who was also HIV positive increased from 6.8% to 10.3% (AOR 1.27, 95% Cl 1.01 to 1.58, p<0,05). Conclusion: The increase in high risk sexual behaviour among London homosexual men between 1998 and 2003 was seen only with casual and not with main partners. STI/ HIV prevention campaigns among London homosexual men should target high risk practices with casual partners since. these appear to account entirely for the recent increase in high risk behaviour.

This paper describes a study among HIV-negative gay men in London to examine willingness to volunteer for an HIV vaccine trial. HIV-negative gay men ( n =506) were surveyed in central London gyms in February-March 2002. Information was collected on willingness to volunteer for an HIV vaccine trial, attitudes toward HIV vaccines and sexual risk behaviour. Men reporting unprotected anal intercourse (UAI) in the previous three months with a man of unknown or discordant HIV status were classified as being at high risk of exposure to HIV ( n =94, 18.6%). The remainder, who reported no UAI or UAI only with another HIV-negative man, were considered to be at low risk ( n =412, 81.4%). Just under a quarter of the HIV-negative men in the study (23.4%) said they were either quite likely or very likely to volunteer for an HIV vaccine trial. High-risk men were more likely to say they would volunteer for a trial than low-risk men (37.2% versus 20.2%, p <0.001). Of the 506 HIV-negative men surveyed, eight (1.6%) were both high risk and very likely to volunteer for an HIV vaccine trial, while a further 27 (5.3%) were both high risk and quite likely to volunteer. Based on these figures, we estimated that to recruit 1,000 high-risk HIV-negative men into a vaccine trial between 15,000 and 62,000 HIV-negative men would need to be approached in the community. Compared with those at low risk, a greater proportion of high-risk men said that if they were in an HIV vaccine trial they would be more likely to have unprotected sex (23.4% versus 7.8%, p <0.001); that an effective vaccine will make safe sex less important (45.7% versus 31.3%, p =0.01); and that they would participate in an HIV vaccine trial even if they thought the vaccine might not work (46.8% versus 29.9%, p <0.01). This study suggests that, in London, to recruit high-risk HIV-negative gay men for an HIV vaccine trial many thousands of gay men may need to be approached in the community. Some HIV-negative men said that they would be more likely to have unprotected sex if they took part in a trial . [ABSTRACT FROM AUTHOR]

A peer-led HIV prevention initiative, based on a diffusion of innovation model, was developed for gay men attending gyms in central London. Peer educators were recruited from people who used the gym regularly according to standard selection criteria. After initial training, peer educators agreed to talk to gay men at their gym about HIV prevention, focusing on sexual risk and steroid injecting behaviour. Outcome evaluation revealed that the peer education programme had no significant impact on the risk behaviours of gay men using the gyms. Process evaluation, based on interviews with peer educators, the health promotion team and gym managers threw light on this finding. While it was feasible to set up a peer education programme among gay men in central London gyms, attrition was an important factor. Only one in five potential peer educators initially identified remained with the project throughout, thus limiting the potential for diffusion. Those who did work as peer educators reported barriers to communication within the gyms further limiting the extent to which diffusion occurred. In fact, it appears that the critical mass required for diffusion was never established. This could explain why the intervention had no significant impact on gay men's risk behaviours. A person-time analysis demonstrated that the peer education programme required a substantial input from the health promotion team, equivalent to one team member devoting 2.5 days a week to recruit, train and support peer educators over 18 months. Peer education should not, therefore, be viewed as a low-cost approach to prevention. Many of the insights gained through this process evaluation can inform others planning peer education programmes in other settings. [ABSTRACT FROM AUTHOR]

Controlled trials conducted in the U.S. provide persuasive evidence that peer education can bring about a significant reduction in high risk sexual behavior among homosexual men. These peer education programmes drew on a diffusion of innovation model whereby popular opinion leaders engaged in conversation with other homosexual men to promote HIV risk reduction. The Mpowerment project in California and Oregon also reported a significant reduction in the frequency of unprotected anal intercourse with both regular and casual partners following a peer led intervention.
