Binge Drinking in College Can Lead to Later Cardiac Issues
Students beware, a college habit of binge drinking can cause serious problems in later life.
A new study finds that regularly consuming multiple drinks in a short window of time can cause immediate changes in circulation that can increase the risk of developing cardiovascular disease later in life.
“Regular binge drinking is one of the most serious public health problems confronting our college campuses, and drinking on college campuses has become more pervasive and destructive,” said Shane A. Phillips, P.T., Ph.D. “Binge drinking is neurotoxic and our data support that there may be serious cardiovascular consequences in young adults.”
College students age 18 to 25 years old have the highest rates of binge drinking episodes, with more than half engaging in binge drinking on a regular basis. Prior studies have found that binge drinking among adults age 40 to 60 years old is associated with an increase in risk for stroke, sudden cardiac death and heart attack, but the effect on younger adults has not been studied.
In the study, found in the Journal of the American College of Cardiology, researchers looked at two groups of healthy nonsmoking college students — those who had a history of binge drinking and those who abstained from alcohol.
Binge drinking was defined as consuming five or more standard size drinks (12 ounces of beer, 5 ounces of wine, 1.5 ounces of 80 proof spirits or 8-9 ounces of malt liquor) in a two-hour period for males and four or more standard size drinks in a two-hour period for females.
On average, the students who binge drink had six such episodes each month over four years. Abstainers were defined as having consumed no more than five drinks in the prior year.
Students were also questioned about their medical history, diet, history of family alcohol abuse and frequency of binge drinking.
Researchers discovered that the binge drinkers had impaired function in the two main cell types (endothelium and smooth muscle) that control blood flow.
These vascular changes were equivalent to impairment found in individuals with a lifetime history of daily heavy alcohol consumption and can be a precursor for developing atherosclerosis, or hardening of the arteries, and other cardiovascular diseases such as heart attack and stroke.
However, binge drinkers were not found to have increased blood pressure or cholesterol — two well-established risk factors for heart disease.
Interestingly, both high blood pressure and cholesterol cause changes in vascular function similar to what the students demonstrated from binge drinking.
“It is important that young adults understand that binge drinking patterns are an extreme form of unhealthy or at-risk drinking and are associated with serious social and medical consequences,” said Mariann Piano, Ph.D., R.N., co-author of the study.
“Discoveries and advances in many different areas of medical science have cautioned against the notion that youth protects against the adverse effects of bad lifestyle behaviors or choices.”
According to the investigators, more research is needed to determine if damage caused by binge drinking in young adulthood can be reversed before the onset of cardiovascular disease and to determine the timeframe for onset of disease.
