Chennai: There are habitual drinkers, then there are weekend drinkers and social drinkers. A latest study has claimed that oderate drinkers “are not insulated from harm”.
Researchers led by Adam Sherk, of the Canadian Institute for Substance Use Research at the University of Victoria in British Columbia, Canada, found that, in British Columbia, a significant portion of alcohol-caused death and disability was experienced by those drinking within these guidelines.
For example, more than 50 percent of cancer deaths resulting from alcohol use occurred in people drinking moderately. Further, 38 percent of all alcohol-attributable deaths were experienced by people drinking below the weekly limits or among former drinkers
The Canadian government’s low-risk drinking guidelines state that women should consume no more than about 10 drinks per week and men no more than 15. (A ‘drink’ is 12 oz. of beer, 5 oz. of wine, or 1.5 oz. of liquor.) These limits are slightly higher than those in the United States and exceed those of most other high-income countries.
In their research, published in the Journal of Studies on Alcohol and Drugs, Sherk and colleagues found that however, for women, alcohol consumption within the guidelines did offer some protection from death from heart attack, stroke and diabetes. Nonetheless, “[t]his protective effect did not appear to hold for men,” the authors write, “who experienced harm at all drinking levels.”
For their study, the investigators used a new, open-access model–the International Model of Alcohol Harms and Policies (InterMAHP)—which can be used to estimate alcohol harms in a country or state, in total or by drinking group.
They used British Columbia-specific alcohol exposure data from substance use surveys, hospital data from the Canadian Institute for Health Information and mortality data from Statistics Canada’s Vital Statistics.
Because of these results, Sherk and colleagues say that some national drinking guidelines, which are published by many countries to help drinkers make informed health decisions, may be too high. This may be particularly true in Canada, where the research was conducted.
Sherk suggests that guideline limits should be lowered to match those in the Netherlands: “Don’t drink or, if you do, drink no more than one drink per day.”
