Figure.
Prevalence of alcohol dependence among US adult binge drinkers, by binge drinking frequency during the past 30 days, National Survey on Drug Use and Health, 2009–2011. Alcohol dependence for adults was defined as meeting at least 3 of 7 criteria for alcohol dependence (ie, tolerance, withdrawal, impaired control, unsuccessful attempts to cut down or stop drinking, continued use despite problems, neglect of activities, time spent in alcohol-related activity) in the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) and consumed at least 1 drink on 6 or more days in the past 12 months. Binge drinking was defined as consuming 5 or more drinks (men) or 4 or more drinks (women) during a single occasion in the past 30 days. Data set used for 2010 was revised in March 2012. Error bars indicate 95% confidence intervals.
