Gender differences among Veterans with alcohol use disorder nationally in the Veterans Health Administration

Alcohol use among women is increasing relative to men but no study has compared rates and characteristics of women with alcohol use disorder (AUD) to men among Veterans Health Administration (VHA) service users. To compare male and female VHA service users on rates of AUD, and among those with AUD, on sociodemographic characteristics, medical and physical comorbidities, and service and medication use national VHA data from fiscal year (FY) 2012 were used to identify Veterans diagnosed with AUD. Bivariate analyses evaluate gender differences in: sociodemographic characteristics; comorbid medical and psychiatric diagnoses; service use and psychotropic prescription fills. Multivariate stepwise logistic regression was used to identify a parsimonious set of differences. About 13,797 of all 349,430 women served by VHA in FY 2012 (3.94%) were diagnosed with AUD as compared to 331,407 of 5,102,877 men (6.50%) for a risk ratio of 0.608 for AUD among women. Women were younger, more likely to have served in recent Middle East conflicts and had more comorbid psychiatric and substance use diagnoses than men. They filled fewer psychotropic prescriptions (after taking greater number of psychiatric diagnoses in to account), but were more likely to fill a prescription for naltrexone than men. Women had fewer comorbid medical diagnoses than men. Women Veterans with an AUD have higher rates of psychiatric comorbidities than men, highlighting the need for better integration of treatment for AUD and comorbid psychiatric conditions, and suggesting different pathways and potential interventions for AUD in women.
