More than 1 in 4 high school students and adults ages 18 to 34 engaged in a dangerous behavior known as binge drinking during the past month, according to the findings from a report by the Centers for Disease Control and Prevention, a CDC press release states. The report shows that each year more than 33 million adults have reported binge drinking, defined as having four or more drinks for women and five or more drinks for men over a short period of time, usually a couple of hours. And the report said levels of binge drinking have not declined during the past 15 years.

The CDC report found men are more than twice as likely as women to binge drink (21 percent compared to 10 percent). It said binge drinking is more common among non-Hispanic whites (16 percent of whom binge drink) than among non-Hispanic blacks, (10 percent of whom binge drink).

"Binge drinking, increases many health risks, including fatal car crashes, contracting a sexually transmitted disease, dating violence, and drug overdoses," said CDC Director Thomas R. Frieden, M.D., M.P.H. "Excessive alcohol use remains the third leading preventable cause of death in the United States and leads to a wide range of health and social problems."

In this report, CDC scientists analyzed data on self reports of binge drinking within the past 30 days for about 412,000 U.S. adults aged 18 years and older from the 2009 Behavioral Risk Factor Surveillance System (BRFSS) and for approximately 16,000 U.S. high school students from the 2009 National Youth Risk Behavior Survey (YRBS).

"Alarmingly, almost 1 in 3 adults and 2 in 3 high school students who drink alcohol also binge drink, which usually leads to intoxication," said Dr. Robert Brewer, M.D., M.P.H., alcohol program leader at CDC and one of the authors of the report. "Although most binge drinkers are not alcohol-dependent or alcoholics, they often engage in this high risk behavior without realizing the health and social problems of their drinking. States and communities need to consider further strategies to create an environment that discourages binge drinking."

Drinking too much, including binge drinking, causes more than 79,000 deaths in the U.S. each year. Binge drinkers also put themselves and others at risk of car crashes, violence, the risk of HIV transmission and sexually transmitted diseases, and unplanned pregnancy. Over time, drinking too much can lead to liver disease, certain cancers, heart disease, stroke, and other chronic diseases. Binge drinking can also cause harm to a developing fetus, such as fetal alcohol spectrum disorders, if a woman drinks while pregnant.

Binge drinking varies widely from state to state, with estimates of binge drinking for adults ranging from 6.8 percent in Tennessee to 23.9 percent in Wisconsin. It is most common in the Midwest, North Central Plains, lower New England, Delaware, Alaska, Nevada, and the District of Columbia.
