Possible contributors to the gender differences in alcohol use and problems

Research on alcohol use and problems has demonstrated a much higher rate of alcohol use disorders (AUDs) among men compared with women. The authors review the most frequently researched biological and psychosocial factors that may play a role in the gender differences in alcohol use and problems. Among the biological factors, women might carry a lower genetic risk for AUDs and tend to suffer more negative biological consequences from drinking as compared with men. Regarding psychosocial factors, men appear to be more likely than women to manifest certain risk factors for alcohol use and problems (e.g., fewer perceived social sanctions for drinking, positive expectancies for alcohol use, personality traits such as impulsivity) and have fewer protective factors. Although these findings have helped to explain some of the gender differences in alcohol use and problems, there are inconsistencies in the literature. Additionally, many studie may not have enough statistical power to detect gender differences. The authors suggest that the biological and social consequences of alcohol abuse for women may be especially potent protective factors against AUDs and discuss the possibility of public health campaigns developed on the basis of this idea.
