Étude de l’association entre la consommation de cocaïne par épisode de binge et les troubles de santé mentale
Objectives: Although cocaine binges and mental health problems have both been identified as significant risk factors for bloodborne infections and other health hazards, little is known about the relationship between mental health and cocaine binging. Hence, the aim of this study is to examine the association between psychiatric disorders and cocaine binging. Methods: Participants were part of a prospective cohort study of individuals who either smoke or inject cocaine. The main outcome, namely a cocaine binge within the last month, was defined as the repetitive use of large quantities of cocaine until the individual was unable to access more of the drug or was physically unable to keep using. Psychiatric disorders were assessed using the CIDI and the DIS questionnaires. Logistic regression models were performed to examine the association between cocaine binging and psychiatric disorders, adjusting for potential confounders. Results: Of the 492 participants 24.4% reported at least one cocaine binging episode during the prior month. 48.0% of the study population met the criteria for antisocial personality disorder, 45.5% for anxiety disorders, and 28.2% for mood disorders. Participants with antisocial personality disorder were more likely to binge (Adjusted Odds Ratio: 1.73, 95% CI: 1.10-2.73) while those with a mood disorder were not. The association between anxiety disorders and cocaine binging was significant only in univariate analyses. Conclusion: Antisocial personality disorder increased the odds of reporting cocaine binging in our study population. These results highlight the need for a better understanding of the specific dimensions of antisocial personality disorder contributing to the increased risk of unsafe drug use behaviors.
