In 2006, the Behavioral Risk Factor Surveillance System (BRFSS) lowered the threshold for defıning binge drinking among women from Ն5 drinks to Ն4 drinks per occasion, in accordance with national recommendations. Purpose: To assess changes in binge-drinking prevalence among women. Methods: The relative and absolute change in binge drinking among U.S. adult women was assessed using pooled BRFSS data from the 2 years before (2004-2005) and after (2006-2007) the implementation of the new gender-specifıc defınition. Analyses were conducted in 2008-2009. Results: Binge-drinking prevalence among women increased 2.6 percentage points (from 7.3% in 2004-2005 to 9.9% in 2006-2007), a 35.6% relative increase. The percentage of women who reported consuming exactly 4 drinks in 2006 (3.6%) was similar to the increase in the prevalence of binge drinking among women that was observed from 2005 to 2006 (absolute changeϭ2.9 percentage points). Conclusions: The new gender-specifıc defınition of binge drinking signifıcantly increased the identifıcation of women drinking at dangerous levels. The change in prevalence among women was primarily due to the change in the defınition and not to actual changes in drinking behavior. The new gender-specifıc defınition of binge drinking can increase the usefulness of this measure for public health surveillance and support the planning and implementation of effective prevention strategies (e.g., increasing alcohol excise taxes).
