Santos LA. Heterosexually active men and risk management of HIV infection in the context of Post-Exposure Prophylaxis (PEPsexual): experiences in five Brazilian cities [dissertation]. São Paulo: “Faculdade de Medicina, Universidade de São Paulo”; 2019. Introduction: The collective representations that support the ideals of hegemonic masculinity have distanced the heterosexually active men from the responses to the HIV epidemic over the last decades, which has resulted in the increased vulnerability of these individuals in several countries around the world, including Brazil. However, from the new prevention paradigm, Sexual Post-exposure Prophylaxis (PEPsexual), as well as other methods based on the use of antiretrovirals, make possible new ways of managing the risks of HIV infection, while bringing new issues to be addressed. Objectives: The objective of this research is to characterise heterosexually active men and their sexual behaviours, regarding risk and prevention of HIV infection, and to explore the meanings attributed to the risk of contracting HIV and the forms of risk management among heterosexually active men who sought PEPsexual in services in five Brazilian cities. Methodology: The profile and behaviour of the men were described using the quantitative procedure, with data obtained from the initial consultations of sexual PEPs documented in clinical reports. All the records from the men who have searched the services in the years 2014 and 2015 were analysed, and a descriptive analysis was performed. The meaning of risk and the management of the experiences were interpreted using the qualitative approach, through in-depth interviews (16) with users of the services, focusing on the situation that led to the use of the method, as well as the experiences with the use of PEPsexual. For the analysis of the empirical data, the sense interpretation approach was used, according to the hermeneuticdialectic principles. Results: Based on the characteristics described in the quantitative component, the participants are mostly young adults, with a mean age of 31 years, highly educated, white and without previous use of PEPsexual. Most of the sexual HIV risk behaviours happened with a casual partnership. The use of condoms was mentioned by most of the participants; however, condom failure was the main reason for searching the PEPsexual prophylaxis. Most participants reported not knowing the serology of the partner involved in the sexual encounter and the frequency of serological testing for HIV, Hepatitis B and C, Syphilis and Anti-HBs before the episode of sexual exposure was low. The analysis of qualitative data shows that condoms are the main and most widely used method of HIV prevention, but their effective use has been conditioned by diverse subjective and contextual factors. Stable sexual relations offer a greater sense of protection, while the perception of risk increases when the relationships are with casual partnerships or in environments associated with populations most vulnerable to HIV infection, such as sex workers or swing houses. Avoiding or minimizing the number of extramarital relationships, using condoms more consistently, and seeking specialized information emerged as strategies widely used by participants. PEPsexual consisted of an opportunity for thinking on how to prevent not only HIV but also other STIs. The stigma related to the use of antiretrovirals and the need to hide medication from friends and relatives were self-reflexive triggers about personal vulnerability to the epidemic. Participants who planned concrete and detailed prevention actions after using PEPsexual were also those who reported greater self-perception of individual risk. Conclusion: The characteristics of PEPsexual users in the five services studied reveal that heterosexually active white man, highly educated and young are the majority among those who seek PEPsexual prophylaxis; however, great effort should be focused on actions to prevent HIV infection among different segments of heterosexually active men, regarding the social markers of class, colour, race and generation. The ideals of hegemonic masculinity permeated perceptions and risk management discourses to HIV infection. Preventive actions should be undertaken to replace such masculinity patterns in order to reduce the vulnerability of men in general and, more specifically, among heterosexual segments.
