Biomarker In Blood Can Help Identify Young People For Binge Drinking

The biomarker called phosphatidylethanol (PEth), was found to be higher in people who are binge drinkers than those who drink moderately.

A blood test can reveal if an individual is a binge drinker. A biomarker found in the blood of people who consume alcohol is significantly higher in binge drinkers compared to those who consume alcohol moderately, says a new study.

The biomarker, called phosphatidylethanol (PEth), is associated with alcohol consumption and could be used to screen young adults for harmful or heavy drinking such as binge drinking.

Binge Drinking Among Youth On the Rise; Poses Health Risk, Violence and Traffic Accidents
Russia, Estonia, India and China are the countries with highest binge drinking youth while Italy, France and Slovenia showed declines in youth drinking.

"Binge drinking is pervasive on college campuses and among young adults," said lead researcher and professor Mariann Piano from the University of Illinois at Chicago.

"More alarming, though, is the regularity of binge drinking episodes: one in five students report three or more binge drinking episodes in the prior two weeks," she said.

The National Institute on Alcohol Abuse and Alcoholism defines binge drinking as a pattern of drinking that brings a person's blood alcohol concentration to 0.08 or above.

Alcohol-Related Facebook Posts Trigger Binge Drinking in College Students
Students who posted more on social media such as Facebook or twitter about drinking before college actually did more binge drinking in their freshman year.

This typically occurs when men consume five or more drinks in about two hours. For women, it's consuming four or more drinks in the same time period.

The researchers measured PEth in blood samples from student participants at two large Midwestern university campuses. Participants completed a 10-question self-assessment survey to determine their drinking patterns. The majority of participants were Caucasian females.

Rising Number of Adolescents and Young Adults Being Hospitalized Due to Binge Drinking on Birthdays
Binge drinking by adolescents and young adults on their birthdays could lead to a sharp rise in in-patient/emergency department (ED) hospital admissions.

"We discovered a significant correlation between PEth levels in the blood samples and the number of times subjects consumed four-to-five drinks in one sitting within the last 30 days," Piano said.

"Using a biomarker of heavy alcohol consumption, such as PEth, along with self-reporting could provide an objective measure for use in research, screening and treatment of hazardous alcohol use among young adults," Piano added.
