What was done
Face-to-face cross-sectional survey of US household and group quarters residents from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The authors assessed the 12-month prevalence and co-occurrence of DSM-IV alcohol and drug use disorders with independent mood and anxiety disorders (excluding substance-induced disorders and those due to a general medical condition).
What was found
The 12-month prevalence of independent mood disorders was 9.21% (95% CI, 8.78%-9.64%), independent anxiety disorders was 11.08% (95% CI, 10.43%-11.73%), and substance use disorders was 9.35% (95% CI, 8.86%-9.84%). Few individuals with mood or anxiety disorders were classified as having only substance-induced disorders. Positive and statistically significant associations (P < .05) were found between most substance use disorders and independent mood and anxiety disorders.
Why it matters
Shows that co-occurring mood and anxiety disorders in individuals with substance use disorders are overwhelmingly independent rather than substance-induced, arguing against withholding psychiatric treatment in this population.
Limits
The abstract does not state the total sample size or specific odds ratios for individual disorder pairings. The cross-sectional design captures 12-month co-occurrence but cannot determine causal or temporal relationships.
