Summary: Moderate drinkers who have a pattern of binge drinking are five times more likely to develop alcohol use disorders than moderate drinkers who do not binge drink.
Moderate drinkers who binge alcohol are at a significantly higher risk of developing alcohol problems than those who drink the same amount overall but don’t binge, according to a new study from researchers at The University of Texas at Austin appearing in the American Journal of Preventive Medicine.
After analyzing a national sample of US adults, UT Austin psychology professor Charles Holahan, PhD, and his collaborators found that moderate average drinkers with a pattern of binge drinking were almost five times more likely to experience multiple alcohol problems and were twice as likely to experience more alcohol problems nine years later.
Moderate drinking is defined as having on average no more than one drink a day for women and two for men. Binge drinking is defined as consuming five or more drinks on the same occasion.
“What this means,” said Dr. Holahan, “is that an individual whose total consumption is seven drinks on Saturday night presents a greater risk profile than someone whose total consumption is a daily drink with dinner, even though their average drinking level is the same.”
This research supports a growing recognition that binge drinking among adults is a public health concern and calls for increased public health efforts to address such drinking.
Research on binge drinking tends to focus on adolescents and college students, but most binge drinking occurs among adults over 30, and the prevalence of binge drinking in adults is increasing.
However, research on adult alcohol consumption and its effects usually focuses only on a person’s average level of drinking, which masks binge drinking patterns. As a result, the impact of binge drinking among low and moderate adult drinkers has not been well studied or understood.
“In both scientific and media discussions of moderate drinking, the pattern of drinking is generally overlooked,” said Rudolf Moos, PhD, one of the study’s co-authors and professor emeritus of psychiatry and behavioral sciences at Stanford University School of Medicine.
“This leaves many drinkers mistakenly assuming that a moderate average level of consumption is safe, regardless of drinking pattern.”
To get a better understanding of the impact of drinking patterns, the researchers analyzed survey responses from 1,229 drinkers ages 30 and older. The data, taken from two waves of the Midlife Development in the United States study, allowed the researchers to see how respondents’ drinking patterns affected them over nine years.
What the investigators found surprised them: Most cases of binge drinking — and of multiple alcohol problems — occurred among individuals who were average moderate drinkers.
“Much binge drinking among adults escapes public health scrutiny,” said Dr. Holahan, “because it occurs among individuals who drink at a moderate average level. These findings point to a need for alcohol interventions targeting moderate average level drinkers in addition to conventional strategies focusing on the higher risk, but smaller, population of habitually high-level drinkers.”

Binge Drinking and Alcohol Problems Among Moderate Average-Level Drinkers
A significant amount of binge drinking among adults escapes public health scrutiny because it occurs among individuals who drink at a moderate average level. This observational study examined the role of a binge pattern of drinking in predicting alcohol problems among moderate drinkers in a U.S. national sample of adults.
Participants were 1,229 current drinkers aged ≥30 years from 2 waves of the study of Midlife Development in the United States, with a 9-year time lag (2004–2015) (analyzed in 2021‒2022). Negative binomial regression analyses were used to examine the number of alcohol problems, and binary logistic regression analyses were used to examine multiple (≥2) alcohol problems.
Independent of the average level of drinking, binge drinking was linked with an almost 3 times increase in the number of concurrent alcohol problems and a 40% increase in the number of alcohol problems prospectively 9 years later. Moderate average level drinkers accounted for most cases of binge drinking and multiple alcohol problems. Among moderate drinkers, binge drinking was linked with a close to 5 times increase in concurrent multiple alcohol problems and a >2 times increase in multiple alcohol problems prospectively 9 years later.
These results substantially broaden an increasing recognition that binge drinking is a public health concern among adults. Moderate average-level drinkers should be included in efforts to reduce alcohol problems in adults. These findings are applicable to primary and secondary prevention of alcohol problems with the potential to advance population health.
