Alcohol consumption patterns and mortality among older adults with health-related or socioeconomic risk factors

A UK cohort study reveals that even low-risk alcohol consumption is linked to increased mortality among older adults with health-related or socioeconomic risk factors. The findings suggest that healthier lifestyles may play a role in the observed attenuation of mortality for wine drinkers and those who drink only during meals.
