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.

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.

Objetivo: Investigar os fatores associados à prática do sexo sob o efeito de drogas (chemsex), entre homens que fazem sexo com homens portugueses durante período de distanciamento social por COVID-19. Método: Inquérito online aplicado em uma amostra de 1301 participantes residentes em Portugal, recrutados por método Respondent Driven Sampling adaptado ao ambiente virtual. Realizou-se análise descritiva, bivariada e regressão logística para cálculo dos Odds ratio ajustado (ORa). Resultados: A prevalência da prática de chemsex foi de 20,2%. A chance de praticar chemsex aumentou com a prática de sexo grupal (ORa: 28.35, IC95% 16.93 – 47.49); sexo sem uso do preservativo (ORa: 7,09 IC95% 4,57 – 10,99); Utilizar a PrEP (profilaxia pré-exposição) como medida protetiva para a COVID-19 (ORa: 4,16, IC95% 2,71 – 6,39) e; com realização de teste para COVID-19 (ORa: 1,89, IC95% 1,15 – 3,10). Conclusões: A prática de chemsex entre homens que fazem sexo com homens no período da pandemia da COVID-19 em Portugal foi elevada e pode fornecer subsídios para entender o papel e impacto que relações sexuais possuem na atual situação pandêmica da COVID-19 no país.
