Binge drinking among women and girls is a health problem that is serious but under-recognized, the Centers for Disease Control and Prevention says in a report out today.

About 1 in 8 women and 1 in 5 high school girls binge drink, according to the CDC's Vital Signs report. Binge drinking for women is defined as consuming four or more alcohol drinks, such as beer, liquor or wine, on an occasion.

Thestudy found that binge drinking was most common among women ages 18-34and high school girls. It also was most prevalent among women living inhouseholds with annual incomes of $75,000 or higher.

The reportnotes special concerns about binge drinking among females. Women andgirls metabolize, or process, alcohol differently from men and boys.

TheCDC warns binge drinking puts women at a higher risk for breast cancer,sexually transmitted diseases, heart disease and unintended pregnancy.Binge drinking during pregnancy can lead to fetal alcohol spectrumdisorders and sudden infant death syndrome.

David Jernigan,director of the Center on Alcohol Marketing and Youth at the JohnsHopkins Bloomberg School of Public Health in Baltimore, says it iscritical that this problem of binge drinking is highlighted.

"We'vewatched a shift from girls drinking beer to distilled spirits," hesays. "They are experimenting with the strongest form of the drugavailable."

CDC Director Thomas Frieden says there are ways toprevent excessive drinking. He adds, "Effective community measures cansupport women and girls in making wise choices about whether to drink orhow much to drink if they do."
