“…Detailed information on the questionnaires and other procedures are provided in previous publications. [ 3 , 22 ] Briefly, both questionnaires were similar and included data on: eligibility and social network characteristics; socioeconomic and demographic information; HIV/AIDS knowledge, access to health services, including HIV prevention and treatment; history of testing for HIV, syphilis and hepatitis; sexual identity, visibility, violence, stigma and discrimination; and risk behavior, including unprotected sex, illicit drug, and alcohol use. For the 2016 survey, information on HIV post- and preexposure prophylaxis as well as HIV/AIDS treatment were added.…”

Introduction:Periodic monitoring of sociobehavior characteristics at a national level is an essential component of understanding the dynamics the human immunodeficiency virus (HIV) epidemic worldwide, including Brazil.Methods:This paper compares descriptive sociobehavior characteristics in 2 national cross-sectional HIV biological behavioral surveillance surveys (BBSS) conducted in 2009 and 2016 among men who have sex with men (MSM) in Brazil. Respondent driven sampling (RDS) was used for recruitment in both years. Overall proportions were weighted according to Gile's estimator using RDS Analyst Software and 95% confidence intervals were calculated for comparisons between the 2 periods. Further comparisons were stratified by age groups (<25 and 25+ years old).Results:Overall, 3749 and 4176 MSM were recruited in 2009 and 2016, respectively. In 2016, participants were younger than 25 years old (58.3%), with 12 or more years of education (70.4%), with higher socioeconomic status (40.7%), and had a higher proportion of whites (31.8%), as compared to 2009. Also, participants in 2016 reported less alcohol use and binge drinking, but used illicit drugs more frequently. There was an increase among MSM who self-reported their HIV risk as low and had low HIV knowledge while the proportion of those who were never tested for HIV dropped from 49.8% in 2009 to 33.8% in 2016. Although more than three-quarters received free condoms in both years, STD counseling remained low (32% and 38% for 2009 and 2016, respectively). Sexual risk behavior remained at high levels, especially unprotected anal receptive sex and sex with multiple partners. Younger MSM (<25 years old) showed riskier sexual practices than those 25+ years old, when comparing 2016 to 2009.Conclusions:Our results indicate a worrisome risk behavior trend among Brazilian MSM, especially among younger ones. These results can contribute for a better understanding of the HIV epidemics in Brazil, with timely shift in strategies so improved effectiveness in public health prevention efforts can be achieved.

Introduction: High level of HIV/AIDS knowledge is required for an effective adoption of preventive strategies. Objective: To assess HIV/AIDS knowledge among men who have sex with men (MSM) in 12 Brazilian cities. Methods: Respondent-Driven Sampling method was used for recruitment. HIV/AIDS knowledge was assessed by Item Response Theory. Difficulty and discrimination parameters were estimated, and the knowledge score was categorized in three levels: high, medium, and low. Logistic regression was used for analysis. Results: Among 4,176 MSM, the proportion of high level of knowledge was 23.7%. The following variables were positively associated with high knowledge (p < 0.05): age 25+ years old, 12+ years of schooling, white skin color, having health insurance, having suffered discrimination due to sexual orientation, having had a syphilis test, and having received educational material in the previous 12 months. Exchanging sex for money was negatively associated. Conclusions: The proportion of only 23.7% of high HIV/AIDS knowledge was low. We should note that the only potential source of knowledge acquisition associated with high level of knowledge was receiving educational materials. Our study indicates the need for expansion of public prevention policies focused on MSM and with more effective communication strategies, including the development of knowledge that involves motivation and abilities for a safer behavior.

Background: Brazil has a lot of people living with HIV (PLWH) that are still unaware of their own serostatus and has recently integrated HIV self-test (HIVST) into its public health system and offered to key populations such as men who have sex with men (MSM). This study estimates HIVST acceptability among Brazilian MSM and its associated factors. Methods: Respondent-driven sampling (RDS) was used in behavioral and biological surveillance to recruit 4,176 MSM in 12 Brazilian cities in 2016. Descriptive, bivariate and multivariate analyses were conducted. Overall proportions were weighted according to Gile’s estimator using RDS Analyst Software and 95% confidence intervals were calculated. The analyses of HIVST acceptability were stratified by prior HIV testing (never or at least once in a lifetime). Results: We included 3,605 MSM who did not previously know they were PLWH. The HIVST acceptability was 49.1%, lower among those had done HIV test during lifetime compared to those who have never done it (42.7% vs 50.1%), especially among who are in a less vulnerable social context. In the subgroups of MSM who had never had an HIV test, those with complete secondary or incomplete higher school, who reported discrimination, who with a medical appointment in the last 12 months, with high levels of knowledge of HIV/AIDS and who took part in LGBT nongovernmental organization (LGBT-NGO) had higher HIVST acceptability. Among MSM who had taken an HIV test, those who took part in LGBT NGOs had greater HIVST acceptability. We observed a dose-response effect of schooling and knowledge of HIV/AIDS on HIVST acceptability: an increase in both levels was associated with greater acceptability. Conclusions: The findings highlight that it is necessary to improve information about HIVST among MSM more vulnerable in Brazil. Given the acceptability of self-testing and its current adoption in Brazil, we can also point to the need for policies that build on this and enhance timely access to health services and prevention information.
