New UK government research indicates that women in low-income job roles are almost six times as likely to die from alcohol abuse than those in higher paid employment.
The report by the Office for National Statistics found cleaners, sewing machinists and bar staff face 5.7 times greater risk of fatal liver disease, mental disorders and poisoning than doctors and lawyers, reports the Daily Mail.
This was despite richer women downing almost twice as much alcohol, the study finds.
A year ago an ONS report found professional and managerial women are downing almost twice as much alcohol as the lower paid.
They are drinking an average of 10.2 units a week - more than a bottle of wine - compared with 6.5 units for manual workers.
Statistician Myer Glickman, whose team compiled the latest findings, said: "They are an apparent contradiction but it could be down to a number of factors.
"One could be there are other things affecting people's health such as whether they are smokers or have a poorer diet which may make them more vulnerable to the effects of alcohol.
'Also patterns of drinking may be different, such as binge drinking on particular types or brands of alcohol rather than drinking similar or even greater amounts but over a longer period of time," he added.
