(HealthDay News) – Older adults who drink low-to-moderate amounts of alcohol, particularly wine, have lower rates of depression, according to research published online Aug. 30 in BMC Medicine.
Alfredo Gea, of the Universidad de Navarra in Pamplona, Spain, and colleagues followed 5,505 men and women, aged 55–80 years, who were initially free of depression, history of depression, or history of alcohol-related problems, for up to seven years to assess the association between alcohol intake and incident depression.
The researchers found that moderate alcohol intake, defined as 5–15g/day, was significantly associated with lower risk of incident depression (hazard ratio, 0.72). Consumption of 2–7 glasses of wine per week was significantly associated with lower rates of depression (hazard ratio, 0.68).
“Moderate consumption of wine may reduce the incidence of depression, while heavy drinkers seem to be at higher risk,” the authors write.
Several authors disclosed financial ties to companies in the alcoholic beverage, food, and pharmaceutical industries.
