Women who drink to excess are more likely to experience depression and anxiety

Women who drink to excess are more likely to experience depression and anxiety according to new research.

Work done by Dr Rosa Alati, a research fellow from The University of Queensland's School of Population Health, and colleagues from UQ and the University of Bristol, showed women who have more than 15 drinks a week have an increased risk of experiencing mental illness.

However Dr Alati said heavy drinking was also linked to smoking and women from low income groups were more likely to be heavy drinkers.

"In part these relationships may be responsible for the association between heavy drinking and symptoms of anxiety and depression," Dr Alati said.

The research is part of the Mater–University of Queensland Study of Pregnancy (MUSP), which is Australia's largest longitudinal study tracking mothers and their children from pre-birth to early adulthood.

Dr Alati said light drinking – up to 5 drinks per week – was associated with the lowest rates of anxiety and depression when women were in their early 30s.

But at all three assessments, conducted when women were aged in their 20s, 30s and 40s, showed those who drank six or more drinks per week were more likely to have symptoms of depression and anxiety than those drinking less.

"For women in their 20s and 40s the lowest rates of symptoms were in those who did not drink any alcohol," she said.

She said the latest results point to a varying relationship between alcohol and depression and anxiety over the course of a woman's life.
