The level of alcohol consumption was derived from the drinks choices reported by the women, after conversion to standard drinks and then grams of absolute alcohol (g AA) per week. One standard drink in Australia is equal to 10 g of AA. The ‘low’ category was classified as ≤ 70 g AA per week and no more than 20 g AA per occasion. The ‘moderate’ group included women drinking ≤70 g AA/week, but consuming more than 20 g and less than 50 g per occasion. The ‘high’ group included women drinking >70 g AA/week, but never more than 49 g/AA per occasion. Binge drinking was classified as the consumption of ≥50 g AA per occasion.
