Relation entre l'accès à des services pour des problèmes de santé mentale et le partage de matériel d’injection chez des utilisateurs de drogue par injection à Montréal
Objective: The main objective of the present study was to assess the association between access to services for mental health problem and receptive sharing of injection material among people who inject drugs (PWID) in Montréal. Moreover, it wanted to examine the potential modifying effect by the level of psychological distress (PD). Method: At 3-month intervals, between March 2011 and December 2015, participants (n = 358) answered an interviewer-administered questionnaire eliciting information on sociodemographic characteristics, substance use and related behaviours, utilization of services, and mental health indicators. Receptive sharing was defined as having injected with previously used injection material. Access to services for mental health problems was defined as at least one visit to various professionals for mental health problems. PD was measured by the Kessler Psychological Distress Scale (K10). General estimating equation (GEE) analyses were performed. Results: In multivariate analyses, a significant association was found between receptive sharing of injection material and access to services for mental health problems. Age (per 5 years increased) and male gender are associated with a lower likelihood of receptive sharing, while opioids consumption and receptive sharing in the past 3 months at baseline are associated with a higher likelihood of receptive sharing. No evidence of effect modification by psychological distress was found. Conclusion: Among PWID, access to services for mental health problems was associated with a lower likelihood of receptive sharing, regardless of the level of psychological distress.
