Not all factors considered in previous studies, researchers say

TUESDAY, Feb. 10, 2015 (HealthDay News) -- All that talk of red wine and other alcoholic beverages being good for your health if consumed in moderation is just plain wrong, a new analysis contends.
A review of nearly 53,000 British people found little to no health benefit linked to alcohol consumption, once the results were adjusted for a range of personal, social, economic and lifestyle factors, the researchers reported.
"Based on the findings from this study, alcohol consumption appears to confer little to no protection against mortality [death] in most age-sex groups," said study author Craig Knott, a research associate in the department of epidemiology and public health at University College London.
Previous research has shown that light alcohol consumption may confer some degree of protection against early death and illness, with people who have fewer than two drinks per day living longer than both those who drink more and those who don't drink at all, the researchers said.
But these earlier studies were flawed because researchers lumped former drinkers in with people who've never touched a drop, calling all of them non-drinkers and then comparing them to people who imbibe lightly, Knott said.
"Importantly, former drinkers appear to be less healthy and at greater risk of mortality than never drinkers," he said. "With existing research having largely grouped former and never drinkers together, there was the possibility that protective effects seen among lighter drinkers may be less a consequence of a real biological relationship and more a statistical artifact arising from their comparison against people who are simply less healthy."
In this study, published Feb. 10 in the BMJ, researchers compared interview data from the annual Health Survey for England with national death records, analyzing the drinking habits and health of almost 53,000 people aged 50 and older.
Compared with people who never drank, any protective benefits from alcohol were largely limited to men aged 50 to 64 who reported having an average 15 to 20 drinks a week, and women 65 and older who had an average 10 drinks or less per week, the investigators found.
