RESUMO
This study aimed to evaluate unprotected receptive anal sex intercourse (URAI) rates and vulnerabilities to HIV infection among men who have sex with men (MSM) that use geosocial networking dating apps in Brazil. An online, analytical, cross-sectional study was carried out with 2,250 MSM. The analyzed variables were grouped according to domains of vulnerability and analyzed by bi and multivariate statistics to calculate the Adjusted Odds Ratios (aOR). The prevalence of self-reported HIV was 7.1%; and of URAI, 23.4%. The studied variables that increased the chances of engaging in URAI were: identifying as homosexual (aOR = 8.30; 95%CI = 5.68:12.04), pansexual (aOR = 5.01; 95%CI = 2.04:12.38), or bisexual (aOR = 3.14; 95%CI = 2.03:4.80), using apps for obtaining sex (aOR = 1.3; 95%CI = 1.0:1.5), engaging in group sex (aOR = 1.6; 95%CI = 1.3:2.0), and reporting chemsex (aOR = 1.5; 95%CI = 1.1:2.0). Self-reported positive HIV status was associated with: less than a minimum wage income (aOR = 1.78; 95%CI = 1.22:2.58), lower education (aOR = 1.86; 95%CI = 1.31 CI; 2,64), not knowing the partner's HIV status (aOR = 1.84; 95%CI = 1.06:3.19), practicing group sex (aOR = 1.67; 95%CI = 1.04; 2.68), and chemsex (aOR = 2.03; 95%CI =1.06:3.19). The applications interaction is shaped by their own users to better meet their desires and needs. However, this behavior exposes individuals to HIV vulnerabilities.

BACKGROUND: The objective of the present study was to analyze the factors associated with non-completion of the hepatitis B vaccine series among men who have sex with men and use geosocial dating apps in Brazil. METHODS: This was a cross-sectional, population survey-based, analytical study, conducted exclusively online in all the regions of Brazil, with a sample of 1855 men who have sex with men. The data was collected between November 2016 and February 2017, using the social networking website Facebook. RESULTS: Univariate, bivariate and multivariate analyses showed that 4.7% of the participants reported receiving one dose of the vaccine, 12.5% two doses, 19.4% three doses, and 45.8% did not know. Multivariate analysis showed that level of education (OR = 0.31; CI 95% 0.14-0.72; p = 0.007), identification as bisexual (OR = 0.6; CI 95% 0.38-0.95; p = 0.030), HIV serological status (OR:2.3; CI 95% 1.58-3.34; p = < 0.001) and frequency of access to health services (OR = 2.38; CI 95% 1.53-3.72; p = < 0.001) were associated with not completing the vaccine series. Low completion of the hepatitis B vaccine series was detected in the population studied. CONCLUSION: Completion of the hepatitis B vaccine series was low among men who have sex with men and use geosocial dating apps in Brazil. The factors associated with non-completion were related to social, individual and healthcare (programmatic) vulnerabilities.
