RESUMO
The objective of this cross-sectional survey was to assess the prevalence of psychoactive substance use (PSU) in people attending 11 French Sexual Transmitted Infection Centers, and to specify their profiles (PSU and link with risky sexual behaviors) using the ascending hierarchical clustering method. Among the 5220 individuals who completed the survey, 55.6% were men and the median age was 24 years [IQR: 20-31]. Among the participants, 2751 (52.7%) reported PSU at least once in their life. Ascending hierarchical clustering identified seven distinct profiles of participants based on their PSU. This study shows a high prevalence of PSU and alcohol consumption in this young population. Moreover, subgroup analysis allowed identifying groups of psychoactive substance users who presented specific risks or vulnerabilities and who should be priority targets for interventions, particularly sexual minority groups.
