RESUMO

Abstract A scoping literature review to identify the multilevel HIV serosorting related elements was developed. Articles from EBSCO, PubMed, PsyNET and Science Direct with serosort* or serosorting at the tittle or abstract, written in English or Spanish were included. No restriction in type of population or design were applied. 239 records were retrieved after duplicates removed, but 181 references were extracted for full-text review. Individual level: HIV knowledge, serostatus, risk perceptions, abilities to disclose and for condom use negotiation, motivations, use of drugs, stigma, attitudes toward condom use, and perceptions/beliefs about the HIV and related treatments, HIV infection rates/testing and behavioral factors. Interpersonal level: social networks, abilities (sexual behavior negotiation, and communication). Community level: stigma, social norms, access to HIV related services. Structural level: political context, HIV related funding and public policies. HIV Serosorting is not solely an interpersonal behavior it involves multilevel elements that must be acknowledged by professionals and stakeholders.

Resumen Se desarrolló una revisión de alcance de la literatura para identificar elementos multinivel relacionados a la seroclasificación de VIH. Se incluyeron artículos de EBSCO, PubMed y Science Direct con serosort* o serosorting en título o resumen, escritos en Inglés o Español. No se aplicaron restricciones por tipo de población y diseño. Después de remover duplicados, se recuperaron 239 records, solo 181 referencias se extrajeron para revisión a texto completo. Nivel individual: Conocimiento del VIH, seroestado, percepciones de riesgo, habilidades para develar el seroestado y negociar el condón, motivaciones, uso de drogas, estigma, actitudes sobre uso del condón, y percepciones/ creencias acerca del VIH y tratamientos, tasas de infección y tamizaje de VIH, factores conductuales. Nivel interpersonal: redes sociales, habilidades (negociación de la conducta sexual, y comunicación). Nivel comunitario: Estigma, normas sociales, acceso a servicios de VIH. Nivel estructural: contexto político, políticas públicas y financiamiento relacionado al VIH. La seroclasificación de VIH no es solamente una conducta interpersonal, incluye elementos multinivel que deben ser reconocidos por los profesionales de salud y tomadores de decisiones.

RESUMO

Resumo O texto discute gestões de risco para o HIV no sexo anal desprotegido (SAD) realizadas por homens que fazem sexo com homens (HSH). Está embasado na análise de 25 entrevistas com enfoque biográfico com HSH e observação participante na comunidade gay do Recife. Os homens utilizam a soroescolha: SAD com parceiros de mesma sorologia. Além da testagem, são empregados outros indicadores para inferir a condição sorológica negativa. Estilizações corporais, nuançadas pelos vínculos com os parceiros, produzem emoções que medeiam o SAD. Dada a precariedade dos indicadores utilizados, os homens recorrem muito ao teste anti-HIV. Este acontece após a exposição ao risco, como um ritual reparador para o drama do sexo desprotegido, mas sem eficácia preventiva individual.

Abstract The text discusses HIV risk management in unprotected anal sex (UAS) carried out by men who have sex with men (MSM). It is based on analyses of 25 interviews with a biographical focus with MSM, and participant observation in the gay community of Recife. The men use serosorting: UAS is chosen with partners of the same serology. Besides testing, other indicators are used to infer a serologically negative condition. Body stylizations, nuanced by affective bonds with the partners, produce emotions which mediate the willingness to engage in UAS. As they understand the precariousness of the indicators used, the men often resort to testing. This takes place after exposure to risk, as a repairing ritual for the drama of unprotected sex, but without any individual preventative effectiveness.

Resumen El texto discute el manejo del riesgo para el VIH en el sexo anal sin protección (SASP) llevado a cabo por hombres que tienen sexo con hombres (HSH). Se basa en el análisis de 25 entrevistas con enfoque biográfico con HSH y la observación participante en la comunidad gay de Recife. Los hombres utilizan el "suero elección": elige para el SASP parejas de la misma serología. Además de las pruebas, utilizan otros indicadores para inferir una condición serológica negativa. Estilizaciones corporales, matizadas por los vínculos afectivos con parejas sexuales, producen emociones que median el SASP. Como entienden la precariedad de los indicadores utilizados, los hombres a menudo recurren a las pruebas. Esto ocurre después de la exposición al riesgo, como un ritual de reparación para el drama del sexo sin protección, pero sin ninguna eficacia preventiva individual.

RESUMO

Although previous research has focused on injection drug use behaviors in both urban and rural settings, few have drawn direct comparisons between adjacent rural and urban areas. Using data from the National HIV Behavioral Surveillance study as well as original data collected in a similar fashion, we compare the risk behaviors of people who inject drugs (PWID) in San Juan, Puerto Rico, with those of PWID in nearby rural areas. Specifically, we examine whether one's own hepatitis C (HCV) infection status can be used to predict whether one asked their most recent co-injection partner about their HCV status. Acquiring such information allows injectors to seek out co-injection partners of concordant status as a way to minimize the risk of viral transmission. Results indicate that urban PWID with a known HCV+ status were more likely to know their last co-injector partner's HCV status than were their peers with a negative or unknown HCV status. However, this relationship was not present in the rural data. These findings suggest that there are different risk norms in rural and urban PWID communities and that interventions successful in one type of community may not be so in others.

RESUMO

ABSTRACT Brazil is characterized by a concentrated AIDS epidemic, it has a prevalence of less than 1% in the general population. However, there are higher rates in specific populations, especially in men who have sex with men. The study's aim was to analyze the association between sociodemographic characteristics, sexual practices, sexual behaviors and the HIV infection in a group of men who have sex with men. Secondary data was collected between June 2014 and September 2015 in a research of cross-sectional design in the city of Rio de Janeiro, Brazil. Volunteers answered an online computerized questionnaire and took HIV test. Chi-squared distribution and multiple logistic regression was used. There were 341 participants. Most of them were racially mixed, single, average age of 30.6 years and with a higher education level. The HIV prevalence was 13.9%. Two logistic models were fit (insertive or receptive anal intercourse). Both models showed an association with HIV among those who had a HIV positive sexual partner (Odds Ratio ≈ 2.5) and a high self-perception of acquiring HIV (Model 1: Odds Ratio ≈ 7/Model 2: Odds Ratio ≈ 10). Low condom usage in receptive anal intercourse with casual partners had a direct association with HIV seropositivity, whereas insertive anal intercourse with casual partners with or without condoms were inversely related. The study identified a high prevalence of HIV infections among a group of men who sex with men with a high self-perception risk of acquiring HIV. The findings also showed a relation with sociodemographic and sexual behavior variables.

RESUMO

Due to the high cost of treatment, preventative measures to limit Hepatitis C (HCV) transmission among people who inject drugs (PWID) are encouraged by many public health officials. A key one of these is serosorting, where PWID select risk partners based on concordant HCV status. Research on the general U.S. population by Smith et al. (2013) found that knowledge of one's own HCV status facilitated serosorting behaviors among PWID, such that respondents with knowledge of their own status were more likely to ask potential partners about their status prior to sharing risk. Our objective was to see if this held true in rural Puerto Rico. We replicate this study using a sample of PWID in rural Puerto Rico to draw comparisons. We used respondent driven sampling to survey 315 participants, and have a final analytic sample of 154. The survey was heavily modeled after the National HIV Behavioral Survey, which was the dataset used by the previous researchers. We found that among PWID in rural Puerto Rico, unlike in the general population, knowledge of one's own HCV status had no significant effect on the selection of one's most recent injection partner, based on his/her HCV status. We conclude that PWID in rural Puerto Rico differ from the general U.S. population when it comes to serosorting behaviors, and that these differences should be taken into account in future outreaches and intervention strategies.

RESUMO

ABSTRACT A spectrum of diverse prevention methods that offer high protection against HIV has posed the following challenge: how can national AIDS policies with high coverage for prevention and treatment make the best use of new methods so as to reverse the current high, and even rising, incidence rates among specific social groups? We conducted a narrative review of the literature to examine the prevention methods and the structural interventions that can have a higher impact on incidence rates in the context of socially and geographically concentrated epidemics. Evidence on the protective effect of the methods against sexual exposure to HIV, as well as their limits and potential, is discussed. The availability and effectiveness of prevention methods have been hindered by structural and psychosocial barriers such as obstacles to adherence, inconsistent use over time, or only when individuals perceive themselves at higher risk. The most affected individuals and social groups have presented limited or absence of use of methods as this is moderated by values, prevention needs, and life circumstances. As a result, a substantial impact on the epidemic cannot be achieved by one method alone. Programs based on the complementarity of methods, the psychosocial aspects affecting their use and the mitigation of structural barriers may have the highest impact on incidence rates, especially if participation and community mobilization are part of their planning and implementation.

RESUMO A existência de diferentes métodos preventivos que oferecem elevado grau de proteção contra o HIV tem trazido à luz um desafio: como países que proporcionaram ampla cobertura de prevenção e tratamento poderão utilizar novos métodos preventivos para reverter taxas de incidência que permanecem elevadas, até mesmo crescentes, em grupos sociais específicos? Realizamos uma revisão narrativa da literatura com a finalidade de examinar os métodos preventivos e as intervenções estruturais que, no contexto de epidemias concentradas populacional e geograficamente, podem ter maior impacto nas taxas de incidência. Com isso, analisamos o conhecimento acerca do grau de proteção dos diferentes métodos, seus limites e suas potencialidades. O alcance e a efetividade dos métodos têm sido minimizados, notadamente, por barreiras estruturais e psicossociais, como falhas de adesão, uso inconsistente ao longo do tempo ou apenas em situações em que as pessoas se percebem em maior risco. Indivíduos e grupos sociais mais atingidos pela epidemia têm limitado o uso e o não uso de métodos de acordo com seus valores, necessidades identificadas de prevenção e condições de vida. Isso impede que um método isoladamente venha a promover um forte impacto de redução na epidemia. Políticas baseadas na oferta conjunta e na complementaridade entre os métodos, na atenção aos aspectos psicossociais que interferem no seu uso e na redução das barreiras estruturais de acesso poderão ter maior impacto na incidência, especialmente se forem planejadas e implantadas com participação e mobilização social.
