Alcoholic Girls of Eleven Britain has an enormous problem, one that has emerged only during the past 10 years and shows in this statistic: Underage teenage girls in Britain are now binge-drinking more than boys, with girls as young as 11 hooked on alcohol. One-quarter of all children ages 11-15, in fact, admitted trying alcohol within a period of a week, many of them admitting to drinking five to 10 pints in a week, according to Britain's Institute for Alcohol Studies. For that age group, those figures are second only to those for children in Denmark. The survey, completed last month, is one of many finding increases in drinking, particularly binge drinking, defined here as at least five drinks in a sitting. According to the government, this new breed of drinkers has led to the hospitalisation of an average of 13 children a day, suffering from the toxic effects of bingeing. "The number of children admitted to hospital for alcohol-related disease is shocking," said Paul Burstow, a Liberal Democratic member of parliament, speaking during a debate on how to curtail the binge drinking. "It shows that binge drinking amongst teenagers is completely out of control."
