Objective: to investigate the factors associated with the practice of sex under the influence of drugs (chemsex) among Portuguese men who have sex with men during the period of social distancing to prevent the COVID-19. Method: online survey applied in May 2020 to a sample of 1,301 participants living in Portugal, recruited according to Respondent Driven Sampling and via social media Facebook®. Descriptive and bivariate analyses were performed along with logistic regression to calculate adjusted Odds Ratio (ORa). Results: the prevalence of chemsex was 20.2%. The likelihood of practicing chemsex increased with group sex (ORa: 28.4, 95%CI 16.93–47.49); unprotected sex (ORa: 7.1 95%CI 4.57–10.99); the use of pre-exposure prophylaxis (PrEP) to prevent COVID-19 (ORa: 4.2, 95%CI 2.71–6.39) and COVID-19 testing (ORa: 1.9, 95%CI 1.15–3.10). Conclusion: the practice of chemsex among men who have sex with men during the COVID-19 pandemic in Portugal was very frequent and may support greater understanding of the role and impact of sexual behavior on the COVID-19 transmission rates and the current pandemic situation in Portugal.
Investigar os fatores associados à prática do sexo sob o efeito de drogas (chemsex) entre homens que fazem sexo com homens (HSH) durante período de isolamento social, no contexto da pandemia da COVID-19. Inquérito multicêntrico online, aplicado aos territórios de Brasil e Portugal em abril de 2020, enquanto os dois países vivenciavam medidas sanitárias restritivas para a doença. Os participantes foram recrutados valendo-se de uma adaptação do método respondent driven sampling (RDS) ao ambiente virtual. Os dados foram coletados usando redes sociais e aplicativos de encontro voltados a HSH. Utilizamos regressão logística bivariada e multivariada para a produção das odds bruto (OR) e ajustado (ORa). Em um universo de 2.361 sujeitos, 920 (38,9%) realizaram a prática do chemsex, que, em 95% dos casos, foi realizada com parceiro casual. Aumentaram as chances de se envolver em chemsex: morar no Brasil (ORa = 15,4; IC95%: 10,7-22,1); não estar em isolamento social (ORa = 4,9; IC95%: 2,2-10,9); fazer sexo casual durante o distanciamento social (ORa = 52,4; IC95%: 33,8-81,4); fazer sexo grupal (ORa = 2,9; IC95%: 2,0-4,4); não apresentar nenhum tipo de sintoma para a COVID-19 (ORa = 1,3; IC95%: 1,1-1,8); não residir com o parceiro (ORa = 1,8; IC95%: 1,2-2,6) e estar em uso da profilaxia pré-exposição (ORa = 2,6; IC95%: 1,8-3,7). A ocorrência de chemsex foi elevada, sobretudo no Brasil, onde o isolamento social proposto não sensibilizou os HSH à adesão.
Background: There has been tremendous progress in the fight against HIV worldwide; however, challenges persist in the control of HIV infection. These challenges include the high prevalence of late presenters. There are many disadvantages of late presentation—from reduced survival of the infected person to the risk of transmitting the infection. This research aims to analyze the factors that influence the late presentation in patients attending Ndlavela Health Center in Mozambique. Methodology: A retrospective cross-sectional study was carried out at Ndlavela Health Center including patients diagnosed with HIV between 2015 and 2020. The European Late Presenter Consensus working group definitions were used, and univariate and multivariate logistic regression were used to identify factors associated with late presentation. Results: In total, 519 participants were included in the study, of which nearly 47% were classified as late presenters. The male gender (AOR = 2.41), clinical suspicious test (AOR = 4.03), initiated by the health professional (AOR = 2.1,9), and fear of stigma (AOR = 2.80) were the main risk factors for late HIV presentation. Conclusion: Factors that are potentially determinant for late HIV presentation were identified. Actions are needed to focus on risk factors that are most likely to delay presentation.
