The percentage of women who binge drink has doubled since the 1990s, according to the latest research. The Joseph Rowntree Foundation study found 15% of women now binged on alcohol each week. In men, the figure stood at 23% - a small rise on previous statistics. The Joseph Rowntree Foundation commissioned researchers from Oxford Brookes University to look at a range of sources for the research, including Office for National Statistics data and government reports. They found that average alcohol consumption had risen for both men and women since the mid 1990s. The study said the weekly intakes for men now stood at between 18 and 19 units, up from 15 to 16, and for women it was currently nine to 10, up from six to seven. Men aged 45 to 64 were the biggest drinkers, consuming over 20 units a week on average, overtaking 16 to 24-year-old men who were the biggest drinkers a couple of years ago.
