Engagement in treatment for depression among people who inject drugs in Baltimore, Maryland

Abstract

IntroductionMental health care may mitigate negative consequences related to substance use and bolster engagement in care for drug dependence. Despite the increased risk of depression among people who inject drugs (PWID), the longitudinal relationship of depression symptoms with depression and drug treatment utilization in this population remains uncharacterized. MethodsData on depressive symptoms and depression treatment from current and former PWID in the ALIVE (AIDS Linked to the IntraVenous Experience) community-based cohort who had ≥3 study visits from July 2005 to June 2016 were included. We used logistic regression analysis with generalized estimating equations to examine factors associated with depression treatment in the 12 months following reported major depressive symptoms (CES-D ≥ 23) in the absence of treatment. We further examined the association between depression, depression treatment, and subsequent engagement in drug treatment among those with active substance use or alcohol dependence. ResultsOf the 1544 participants, 34% were female, the median age was 51 years, and 91% were African-American. PWID reported major depressive symptoms at 22% of study visits. In adjusted analysis, acute emergency care, suicidal ideation, and recent alcohol or drug treatment were positively associated with initiating depression treatment. Depression was positively associated with subsequent treatment for substance dependence among those actively using (aOR = 1.30, 95% CI: 1.10–1.53). ConclusionsPWID experience a high burden of depressive symptoms with significant unmet need of treatment for depression. Our findings suggest that mental health providers should bolster connections to chronic disease and alcohol and drug treatment providers.
