Study:

Problematic alcohol use male/female ratio declined from 3.0 in the 1891–1910 birth cohort to 1.2 in the 1991–2000 birth cohort.

“These results have implications for the framing and targeting of alcohol use prevention and intervention programmes. Alcohol use and alcohol-use disorders have historically been viewed as a male phenomenon. The present study calls this assumption into question and suggests that young women in particular should be the target of concerted efforts to reduce the impact of substance use and related harms,” they say.
