Correlates of Co-Occurring Depressive Symptoms and Alcohol Use in an Older Primary Care Clinic Population

Abstract

ABSTRACT Objective: This report describes the prevalence and correlates of co-occurring depressive symptoms and alcohol use in an older Veteran's Affairs primary care clinic population. Methods: Participants include 8,782 older primary care patients (age 65 +) who responded to a self-report, mailed survey. Patients were classified into six mutually exclusive groups based upon screening indicators for problem drinking (quantity/frequency questions) and depressive symptoms (General Health Questionnaire). Groups included: (a) neither problem drinking nor depressive symptoms (n = 6,415, 73.0%); (b) at-risk alcohol use (n = 761; 8.7%); (c) heavy alcohol use (n = 201; 2.3%); (d) depressive symptoms (n = 1,234, 14.1%); (e) depressive symptoms and at-risk alcohol use (n = 120; 1.4%); and (f) depressive symptoms and heavy alcohol use (n = 51; 0.6%). Chi-square and ANOVA were used to test for equality of demographic and clinical characteristics across groups. Results: 12.9% of patients reported alcohol use consistent with problem drinking (including 10.0% with at-risk alcohol use and 2.9% with heavy alcohol use) and 16.1% screened positive for possible depressive symptoms (including 2.0% with co-occurring at-risk or heavy alcohol use). The combination of heavy alcohol use and depressive symptoms was associated with the highest rates of death and suicidal ideation; living alone; being divorced, separated, or widowed; and regular cigarette smoking. The presence of depressive symptoms (regardless of amount of alcohol use) was associated with worse perceived health, and perceived lack of social support. Finally, individuals with at-risk alcohol use alone were younger and had better perceived health compared to those with non-problem alcohol use or no alcohol use. However, there were no differences between those with at-risk drinking and depressive symptoms and those with depressive symptoms alone. Conclusions: Self-reported heavy alcohol use combined with depressive symptoms identifies a subgroup of older primary care patients at especially high risk with respect to suicidal ideation and poor mental and physical well-being. In contrast, older adults with depressive symptoms and self-reported “at-risk” alcohol use were not differentiated from older persons with depressive symptoms reporting non-problematic or nonuse of alcohol.
