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. (Am J Addict 2015;XX:XX-XX).
