Genetic and environmental influences on alcohol consumption in middle to late life.

ABSTRACT:

Objective

Alcohol use is common in older adults and linked to poor health and aging outcomes. Studies have demonstrated genetic and environmental contributions to the quantity of alcohol consumption in mid-to-late life, but less is known about whether these influences are moderated by sociodemographic factors such as age, sex, and educational attainment. This study sought to better understand sociodemographic trends in alcohol consumption across the second half of the life course and their underlying genetic and environmental influences.

Method

Primary analyses were based on 64,140 middle-aged or older adult twins (40-102 years) from 14 studies in the Interplay of Genes and Environment Across Multiple Studies consortium. We harmonized a measure of weekly alcohol consumption
