The effect of moderate alcohol use on the relationship between stress and depression.

Author information

Alcohol Research Group, Berkeley, Calif.



The purpose of the study was to determine whether moderate alcohol use mediates or buffers the effect of stress on depression in a group of non-Hispanic White men and women.


Data are from the Los Angeles Epidemiological Catchment Area cohort. Individuals were assessed at two time periods, 1 year apart. Mean depression scores were analyzed for each level of stress and alcohol use.


In the simultaneous presence of both chronic strain and negative life events, a U-shaped pattern was observed in which abstainers and light and heavy drinkers had higher depression scores at the second time period than did light-moderate and moderate alcohol users. The U-shaped relationship remained when the effects of sex, age, and physical health status were controlled.


Light-moderate and moderate drinkers had less depression in the presence of stress than persons in other more extreme drinking categories. Moderate alcohol use may serve as a proxy for a spectrum of generally moderate behaviors that either attenuate the effect of stress on depression or suppress the effects of stress.
