Study: Younger Women Drinking Alcohol More Like Men


Women are closing the gender gap with men when it comes to drinking alcohol, a recent analysis by scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA) suggests.

In the United States, and throughout the world, men drink more alcohol than women.  But those longstanding differences between men and women in alcohol consumption and alcohol-related harms might be narrowing in the United States, scientists say.

Researchers led by Aaron White, Ph.D., NIAAA’s senior scientific advisor to the director, examined data from yearly national surveys conducted between 2002 and 2012.

“We found that over that period of time, differences in measures such as current drinking, number of drinking days per month, reaching criteria for an alcohol use disorder, and driving under the influence of alcohol in the past year, all narrowed for females and males,” says Dr. White. “Males still consume more alcohol, but the differences between men and women are diminishing.” 

“This study confirms what other recent reports have suggested about changing patterns of alcohol use by men and women in the U.S.,” notes NIAAA Director George F. Koob, Ph.D.  Dr. Koob adds that the evidence of increasing alcohol use by females is particularly concerning given that women are at greater risk than men of a variety of alcohol-related health effects, including liver inflammation, cardiovascular disease, neurotoxicity and cancer.

Dr. White and his colleagues found that the percentage of people who drank alcohol in the previous 30 days increased for females from 44.9% to 48.3%, but decreased for males from 57.4% to 56.1% between 2002 and 2012.  Over that time, the average number of drinking days in the past month also increased for females, from 6.8 to 7.3 days, but decreased slightly for males, from 9.9 to 9.5 days.

Binge drinking by 18- to 25-year-olds in college did not change during the decade under study. But among 18- to 25-year-olds not in college, there was a significant increase in binge drinking among females and a significant decrease among males, effectively narrowing the gender gap in binge drinking in this age group.

Dr. White notes that there was only one measure, for any age group, for which the male-female drinking difference actually became greater during the study period.

“The prevalence of combining alcohol with marijuana during the last drinking occasion among 18 to 25 year old male drinkers increased from 15% to 19%,” he says, “while the prevalence of combining alcohol with marijuana during the last drinking occasion among 18 to 25 year old female drinkers remained steady at about 10%.”

Researchers say that the reasons for the converging patterns of alcohol use are unclear and do not appear to be easily explained by recent trends in employment, pregnancy, or marital status, as their analyses controlled for these variables.
