Changes in Alcohol Consumption and Associated Variables among Older Adults in Spain: A population-based cohort study

We examined prospective changes in drinking patterns and their associations with socio-behavioral and health status variables in older adults in Spain using data from a prospective cohort of 2,505 individuals (53.3% women) representative of the non-institutionalized population aged >60 years in Spain. Alcohol consumption was assessed at baseline (2008–10) and at follow-up (2012) with a validated diet history. At risk drinking was defined as consuming >14 g of alcohol/day on average or any binge drinking in the last 30 days; lower amounts were considered light drinking. A total of 26.5% of study participants changed their intake during follow-up. Most participants reduced alcohol intake, but 23.3% of men and 8.9% of women went from light to at risk drinking during the study period. Low social connectivity at baseline was linked to at risk drinking for both sexes. However, the observed associations between changes in social connectivity, morbidity, BMI, or dietary habits and changes in drinking patterns differed by sex. We concluded that since about a quarter of older adults in Spain consume more alcohol than recommended, identifying socio-behavioral factors associated with this behavior is key for designing health campaigns targeting excessive alcohol consumption in this vulnerable population.
