Harvey Finkel of the Boston University Medical Center and colleagues tracked about 5,400 Canadians at age 50.
The study found those who drank in moderation -- no more than 14 drinks a week and no more than three a day for women and four a day for men -- have better overall scores than those who abstained completely from alcohol, The Daily Telegraph reported.
Quality-of-life was measured using the Health Utilities index, which looks at factors including dexterity, emotion, cognition and mobility.
The researchers said regular moderate drinkers scored highest in each of the health indices.
