A study published in November by the American Journal of Epidemiology examined whether light to moderate alcohol use was associated with lower risk of incident physical disability over two 5-year periods in 4,276 non-institutionalised adults in the United States, aged 50 years or older. The study used data from 3 waves of the National Health and Nutrition Examination Survey Epidemiologic Follow-up Study surveys from 1982 to 1992.
Light/moderate drinking (<15> drinking day or 4 per drinking day for women) was associated with reduced risk for incident disability or death over 5 years, compared with abstention (adjusted odds ratio = 0.77; P = 0.008). Among survivors, light/moderate drinking was associated with lower risk for incident disability, compared with abstention (adjusted odds ratio = 0.75; P = 0.009).
In stratified analyses, disability risk decreased with light/moderate drinking in a dose-dependent fashion in men and women with good or better self-reported health but not in men or women with fair or worse self-reported health.
The Study authors conclude that alcohol consumption in moderation might reduce the risk of developing physical disability in older adults in good health but not in those in poor health.
