Abstract

Abstract : Background: Course of alcohol use disorders (AUD) during midlife is understudied, and most research designs are unable to attribute an unambiguous environmental explanation to observed findings. Objectives & Methods: Test whether socio‐contextual factors are linked to differences in the course of problem drinking during midlife. Participants were 163 monozygotic and dizygotic twin pairs concordant for a history of AUD but discordant on problem drinking in the past 10 years. Results: Frequency of drinking with spouse, and peer and emotional problems were associated with discordance. Conclusions and Scientific Significance: Socio‐contextual factors are linked to differences in course of problem drinking in midlife and are not confounded by genetic effects.
