An editorial in The British Medical Journal:
“Given the harms attributed to alcohol use, it is not surprising that reports showing possible mortality benefits for low level users attracted enthusiasm among consumers, the media, and the alcohol industry, along with those who welcomed this as a positive response to accusations that calls for action were based on moral fervour. These apparent benefits are now evaporating, helped along by an important contribution in this week’s issue.”
The paper itself can be found here. From its conclusion:
“Beneficial associations between low intensity alcohol consumption and all cause mortality may in part be attributable to inappropriate selection of a referent group and weak adjustment for confounders. Compared with never drinkers, age stratified analyses suggest that beneficial dose-response relations between alcohol consumption and all cause mortality may be largely specific to women drinkers aged 65 years or more, with little to no protection present in other age-sex groups. These protective associations may, however, be explained by the effect of selection biases across age-sex strata.”
