To examine the role of antiretroviral treatment related perceptions relative to other clinical and psychosocial factors associated with sexual risk taking in HIV positive men who have sex with men (MSM).
Participants were recruited from ambulatory HIV clinics in Montreal. Information on sociodemographic factors, health status, antiretroviral treatment related perceptions, and sexual behaviours was collected using a self administered questionnaire. At-risk sexual behaviour was defined as at least one occurrence of unprotected insertive or receptive anal intercourse in the past 6 months. Multivariate logistic regression was performed to evaluate the associations between at-risk sexual behaviour and covariates.
346 subjects participated in the study. Overall, 34% of subjects were considered at risk; 43% of sexually active subjects (n=274). At-risk sexual behaviour was associated with two antiretroviral treatment related perceptions: (1) taking antiretroviral treatment reduces the risk of transmitting HIV (adjusted odds ratio (OR), 2.10; 95% confidence interval (CI), 1.16 to 3.80); and (2) there is less safer sex practised by MSM because of HIV treatment advances (OR, 1.82; CI, 1.14 to 2.90). Other factors, however, were more strongly associated with risk. These were: (1) safer sex fatigue (OR, 3.23; CI, 1.81 to 5.78); (2) use of "poppers" during sexual intercourse (OR, 6.28; CI, 2.43 to 16.21); and (3) reporting a greater proportion of HIV positive anal sex partners, compared with reporting no HIV positive anal sex partners: (a) <50% HIV positive (OR, 16.79; CI, 4.70 to 59.98); (b) > or =50% HIV positive (OR, 67.67; CI, 15.43 to 296.90).
Despite much emphasis on HIV treatment related beliefs as an explanation for sexual risk taking in MSM, this concern may play a relatively minor part in the negotiation of risk by HIV positive MSM. Serosorting, safer sex fatigue, and the use of poppers appear to be more important considerations in understanding the sexual risk behaviours of HIV positive MSM.

    • "According to a longitudinal study that reported a positive Nattrass association between practicing unsafe sex and HIV optimism, the rise in unsafe sex over time was unrelated to such attitudes and thus could not be explained by them (Elford, Bolding & Sherr, 2002, p. 1542). The rise in unsafe sex may be a consequence of factors other than the availability of HAART — factors such as the replenishment of individuals who enjoy unsafe sex in the population (Boily, Godin Hogben, Sherr & Bastos, 2005), increasing use of 'poppers' (Cox, Beauchemin & Allard, 2004), the rise of Internet dating (Elford et al., 2002; Halkitis & Parsons, 2003), broader changes in sexual culture towards less open discussion of HIV (Morin, Vernon, Harcourt, Steward, Volk, Riess, Neilands, McLaughlin & Coates, 2003) and safe-sex fatigue (Sepkowitz, 2000; Cox et al., 2004). If the rise in new HIV infections is unrelated to HAART, then rolling out HAART to more people will reduce the number of new infections (Blower et al., 2000). "

    ABSTRACT: This paper shows how two publicly available epidemiological modelling packages, namely the Spectrum AIDS Impact Model and the ASSA2003 AIDS and Demographic Model, predict very different impacts from rolling out highly active antiretroviral treatment (HAART) on new HIV infections. Using South Africa as a case study, it shows that the ASSA2003 model predicts a significant drop in new HIV infections as HAART is rolled out, whereas the Spectrum model assumes that HAART does not have a preventative impact (and in fact generates a small increase in new HIV infections). Users will thus draw different conclusions about the public health benefits of HAART depending on which modelling package they use. Despite being presented as a policy-oriented modelling tool capable of exploring 'what if' questions about the impact of different policy choices, the Spectrum model is illequipped to do so with regard to a HAART rollout. Unlike Spectrum, ASSA2003 is more flexible and its assumptions are clear. Better modelling and more information (including about the relationship between HAART and sexual risk behaviour) is required to develop appropriate public-policy modelling for the HAART era.

    • "Ainsi, des initiatives communautaires permettent de mieux apprivoiser ce qu'est « vivre avec le VIH » ou bien encore les règles à observer pour se protéger de l'infection au VIH. Les informations et autres promotions de l'usage du condom et de différentes stratégies sont relativement connues dans l'ensemble, mais pas de tous avec précision, on parle en général de « sécurisexe » (safer sex) (évitement des pénétrations et autres stratégies du genre) ou de réduction des méfaits entre autres par le sérotriage (sero-sorting) où les pratiques sont choisies en fonction du statut VIH du partenaire (Cox, Beauchemin et Allard, 2004).

    ABSTRACT: Building SPOT, a research intervention in HIV prevention, we get in a complex world, researched, influenced by many discourses and care. Gay and homosexual milieus are today co-constructed with AIDS and are not mutually independent. To create a look out on the intervention context, we build a model of this complex context and care for the ways to intervene and communicate in the gay Montreal milieu as well as MSM (men who have sex with men) milieus. This original model is inspired by Foucault (1966), it shows and recalls the necessity to keep a complex perspective in social and public communication of SPOT. Model creation (representing) allowed roles and necessary interactions clarification in actual prevention in Montreal gay world.

    • "Goode, 2001), os resultados desta investigação parecem indicar que esse comportamento em essência não se prende com a procura activa de infecção pelo VIH, mas eventualmente mais com outros factores, tais como a procura de intimidade e de prazer (Carballo-Dieguéz et al., 2006) ou a erotização do risco sexual (Junge, 2002). Além disso, muitos homens que optam por não utilizar preservativos, pelos motivos mencionados ou outros, recorrem frequentemente a uma outra estratégia de prevenção do contágio pelo VIH que é a escolha de parceiros do mesmo estatuto serológico (serosorting, em Inglês) (Cox, Beauchemin & Allard, 2004; Clatts, Goldsamt & Yi, 2005; Parsons et al., 2006). Apesar de não tão eficaz quanto à utilização de preservativos no acto sexual, esta escolha estratégica de parceiros é considerada por muitos como uma forma alternativa de prevenção. "
