The researchers looked at data from between 2002 and 2012 and found that the alcohol consumption reported in the previous 30 days increased amongst women from close to 45% to over 48%, while it dropped amongst men from just over 57% from more than 60%.
Men still drink more alcohol. However, the difference between the two sexes is shrinking, added researchers.
The researchers also found that the average number of days drinking over the last month increased as well amongst women to 7.3 days from 6.8 days, but dropped amongst males to 9.5 days from 9.9 days.
Amongst college students between the ages of 18 and 25 binge drinking did not show a change during the period of the study. However, amongst those people between the ages of 18 and 25 who were not attending college, there was a big increase in the amount of binge drinking amongst females, but a substantial decrease in men.
Binge drinking for men is defined as consuming five drinks or more any given time and in women four drinks or more.
Only one area of drinking showed that the difference amongst men and women increased in the study.
The prevalence of using a combination of alcohol and smoking marijuana over the last time of drinking amongst people between the age of 18 and 25 increase for male drinkers to 19% from 15%, while it with females drinkers of the same age it remained the same at 10%.
Reasons for narrowing the gap in alcohol consumption amongst the sexes are not clear and researchers do not believe they are associated with factors such as pregnancy, marital status or employment.
They said more studies were needed to identify reasons for this trend and how it might affect efforts of both prevention and treatment.
