The study led by University of Western Sydney involved 120 career women between 35-55 years found a dramatic difference in the alcohol life cycle of women and men.
Lead researcher Janice Withnall called it a 'supermum syndrome' where many were drinking in private, denied to reveal the extent of their drinking and were reluctant to seek help habits.
Withnall blames that extent of problem over Australia' drinking culture and feminist movement.
She said that women were drinking to keep up with their colleagues.
According to national figures, 16 per cent per cent of women in the mid-life group suffer alcoholism, but Withnall estimates the figure is closer to 25 per cent.
In the early 1980s we saw more women entering management areas, News.com.au quoted Withnall, as saying.
A lot of business started to be conducted at lunches, dinners and after hours. A lot of career women in their 20s think they need to drink like the boys to get ahead.
Suddenly they hit their 30s and realise they are not in control, she added.
