Alcohol withdrawal in past‐year drinkers with unhealthy alcohol use: Prevalence, characteristics, and correlates in a national epidemiologic survey.

Background: Despite its potential to produce serious adverse outcomes, DSM‐5 alcohol withdrawal syndrome (AWS) has not been widely studied in the general population. Methods: We used cross‐sectional data from 36,309 U.S. adults from the 2012–2013 National Epidemiologic Survey on Alcohol and Related Conditions‐III to examine the past‐year prevalence of AWS and its correlates. We focused on an important clinical population–past‐year drinkers with unhealthy alcohol use–i.e., those with a positive score on the Alcohol Use Disorders Identification Test–Consumption (AUDIT‐C) questionnaire. We also examined the association of AWS with sociodemographic measures, psychiatric disorders, alcohol‐related measures, and healthcare utilization. Results: Approximately one‐third (n = 12,634) of respondents reported unhealthy alcohol use (AUDIT‐C+). Of these, 14.3% met criteria for a DSM‐5 AWS diagnosis. The mean (SE) number of withdrawal symptoms among individuals with AWS was 2.83 (1.88), with the most common being nausea/vomiting and insomnia (19.8% and 11.6%, respectively). Among AUDIT‐C+ respondents, the odds of AWS were significantly higher among males (adjusted odds ratio [aOR] = 1.17 [95% CI, 1.02–1.33]), unmarried participants (aOR = 1.55 [95% CI, 1.25–1.92]), and those at the lowest (vs. highest) income levels (aOR = 1.62 [95% CI, 1.37–1.92]). Among AUDIT‐C+ respondents, AWS was also associated with psychiatric disorders (with aORs that ranged from 2.08 [95% CI, 1.79–2.41]) for major depressive disorder to 3.14 (95% CI, 1.79–2.41) for borderline personality disorder. AUDIT‐C+ respondents with AWS also had higher odds of past‐year alcohol use disorder (aOR = 11.2 [95% CI, 9.66–13.07]), other alcohol‐related features (e.g., binge drinking), and healthcare utilization. Conclusions: Among individuals with unhealthy alcohol use, AWS is prevalent, highly comorbid, and disabling. Given the risk of AWS among unhealthy drinkers, a comparatively large segment of the general population, clinicians should seek to identify individuals with AWS and intervene with them to prevent serious adverse outcomes.
