The long-term trajectory of depression among Latinos in primary care and its relationship to depression care disparities

Abstract

Objective Lower use of medication treatment, poorer doctor–patient communication (DPC) and depression stigma are key contributors to mental healthcare disparities among Latinos with depression. The current study investigated the relationship between these key variables and the long-term trajectory of depression in primary care among Latinos. Method Participants ( N=220) were Latinos presenting to primary care who screened positive for depression. A repeated measures design was used to assess participants at baseline and 6, 25 and 30 months. Repeated measures included depression (Patient Health Questionnaire-9), self-reported quality of DPC and stigma pertaining to antidepressants. Using growth curve modeling, participants' depressive symptom trajectories were examined for a 30-month period. Self-reported utilization of antidepressants, DPC and antidepressant stigma were examined as predictors of the depressive symptom trajectory. In addition, rates of depression improvement/remission and recurrence/relapse were examined. Results Improvement/remission was experienced by 69.4% of participants during a 30-month period. Among those who improved/remitted at 6 or 25 months, 63.4% maintained that improvement/remission by 30 months. The long-term trajectory of depressive symptoms demonstrated a significant positive association with antidepressant stigma and significant negative associations with use of antidepressant treatment and quality DPC. Conclusions While relapse/recurrence is common, most Latinos in this study experienced improvement in depression over 30 months. For many, there is a considerable time to reach improvement/remission. Also, these findings confirm the significance of antidepressant underutilization, DPC and stigma in the long-term outcome of depression among Latinos in primary care.
