- HIV risk perceptions and post-exposure prophylaxis among men who have sex with men in five Brazilian cities(2021) MATHIAS, Augusto; SANTOS, Lorruan Alves dos; GRANGEIRO, Alexandre; COUTO, Marcia TherezaIn the current context of the HIV epi-demic, multiple prevention strategies including biomedical interventions have been presented as alternatives for vulnerable groups. This study investigated homosexuals' and bisexuals' percep-tions of the risk of HIV infection and their expe-riences of using HIV post-exposure prophylaxis (PEP). We conducted a qualitative study with 25 men who have sex with men (MSM) in five Brazilian cities using semi-structured interviews. The results showed that the use of condoms was the main HIV prevention strategy employed by the respondents. In addition, condom failure, in-consistent condom use and intentional non-use are the main prompters of risk perception and the consequent decision to seek PEP. The respondent's perceptions and meanings of the use of PEP were mediated by prior knowledge of PEP. This work broadens the debate on the more subjective aspects of HIV prevention among MSM, especially those related to risk perception and the decision to use PEP in the context of combined prevention.
- Heterosexually active men, masculinities, HIV prevention, and the search for post-exposure prophylaxis following sexual exposure(2019) SANTOS, Lorruan Alves dos; COUTO, Marcia Thereza; MATHIAS, Augusto; GRANGEIRO, AlexandreHegemonic masculinity has distanced heterosexually active men from the responses to the HIV epidemic. However, with the combined prevention paradigm, post-exposure prophylaxis offers new ways to manage the risks of HIV infection, while at the same time bringing about new challenges. The aim of this paper is to discuss - through the lens of gender and masculinities - how heterosexually active men perceive their HIV risk and how they manage prevention methods and strategies, including post-exposure prophylaxis. Employing qualitative methods, 16 heterosexually active men in five health services from different Brazilian cities were interviewed. The analysis indicates that condom use - the main prevention method - was conditioned by subjective and contextual factors, and its failure stands out as the primary reason for seeking out post-exposure prophylaxis. We argue that ideals of hegemonic masculinity permeate perceptions and risk management discourses in the current context of the HIV/AIDS epidemic.
- AIDS- and sexuality-related stigmas underlying the use of post-exposure prophylaxis for HIV in Brazil: findings from a multicentric study(2019) FERRAZ, Dulce; COUTO, Marcia Thereza; ZUCCHI, Eliana Miura; CALAZANS, Gabriela Junqueira; SANTOS, Lorruan Alves dos; MATHIAS, Augusto; GRANGEIRO, AlexandreAIDS-related stigma is a major hurdle to care and it hinders people from accessing HIV prevention methods, such as post-exposure prophylaxis. This study was designed to explore how AIDS-related stigma impacts the experience of using non-occupational post-exposure prophylaxis (nPEP) for HIV after sexual contact. Data were gathered in in-depth interviews with 59 people who voluntarily sought out nPEP in five public healthcare facilities in Brazil between 2015 and 2016. Data were analysed into three thematic categories: fear of being mistaken for a person living with HIV and AIDS (PLWHA); desire to hide particular features of one's sexual life; and experiences of stigmatising behaviour due to nPEP use. Based on the Health Stigma and Discrimination Framework, predominant manifestations of AIDS-related stigma in each category were analysed, as well as their intersections with gender- and sexuality-related stigmas. Results show that experiences of using nPEP are permeated by AIDS-related stigma, intersecting with sexuality- and gender-related stigmas. Stigma experiences are mainly perceived, anticipated and internalised; stigma practices include prejudice and stigmatising behaviours. Taking antiretrovirals (ARVs) led participants to the fear of being discriminated against as a PLWHA and having particular features of their sexual identities disclosed. Thus, hiding nPEP was strategic to protect from stigmatising behaviour. As ARV-based prevention technologies are scaled-up, interventions designed to tackle AIDS- and sexuality-related stigmas must be expanded in Brazil. Required interventions include public campaigns about nPEP, educational programmes in healthcare settings to offer adequate support to nPEP users and investments in stigma research and monitoring.
- Thematic synthesis HIV prevention qualitative studies in men who have sex with men (MSM)(2019) MATHIAS, Augusto; SANTOS, Lorruan Alves dos; GRANGEIRO, Alexandre; COUTO, Marcia TherezaBackground: Qualitative studies on HIV prevention strategies and methods among men who have sex with men (MSM) allow identify knowledge gaps and improve preventive actions. Objective: To make a thematic synthesis of the scientific productions that use the qualitative methodology in the strategies and methods of HIV prevention area among MSM. Methods: We conducted a literature review following the guidelines of the ENTREQ protocol. The analysis included 48 empirical studies published in Portuguese, English and Spanish between 2001 and 2018 available in the Medline, Embase, Scielo, Scopus, Bireme and Web of Science databases. Results: Where an increased production in the last six years and concentration in northern countries. Seven prevention methods were part of the study, with emphasis on pre exposure prophylaxis, testing, condoms and behavioral strategies. The main topics discussed were stigma and support and care networks. Conclusion: we notice that an increasing production on prevention in the men who have sex with men segment results from the emergence of multiple preventive methods and strategies and their combined actions beyond the star role of condoms.
