Synergistic effects of pain and alcohol use in relation to depressive and anxiety symptoms among Latinos in primary care.

Although past work has shown that alcohol use co-occurs with anxiety/depression among Latinos, little work has examined the variables that qualify such associations. The present investigation sought to address whether pain severity (i.e. pain intensity and/or pain-related disability, respectively) moderated relations between hazardous drinking and depressive/anxious arousal symptoms among an economically disadvantaged Latino sample recruited from a primary care medical setting. Participants included 253 adult Latinos (M = 38.5 years, SD = 10.8; 86.6% female) who attended a community-based primary care clinic. There was a significant interaction of hazardous drinking with pain intensity in relation to depressive symptoms and significant interactions of hazardous drinking and pain-related disability in relation to depressive and anxious arousal symptoms. Hazardous drinking was associated with more severe depressive/anxious arousal symptoms only when pain intensity/disability was high. This is the first study to demonstrate the moderating role of pain intensity and disability in associations between hazardous drinking and anxiety/depression among Latinos in a primary care medical setting.
