title: Frequent binge drinking after combat-acquired traumatic brain injury among active duty military personnel with a past year combat deployment.
abstract: OBJECTIVE
  To determine whether combat-acquired traumatic brain injury (TBI) is associated with postdeployment frequent binge drinking among a random sample of active duty military personnel.
  
  
  METHODS
  Active duty military personnel who returned home within the past year from deployment to a combat theater of operations and completed a survey health assessment (N = 7155).
  
  
  METHODS
  Cross-sectional observational study with multivariate analysis of responses to the 2008 Department of Defense Survey of Health Related Behaviors Among Active Duty Military Personnel, an anonymous, random, population-based assessment of the armed forces.
  
  
  METHODS
  Frequent binge drinking: 5 or more drinks on the same occasion, at least once per week, in the past 30 days. TBI-AC: self-reported altered consciousness only; loss of consciousness (LOC) of less than 1 minute (TBI-LOC <1); and LOC of 1 minute or greater (TBI-LOC 1+) after combat injury event exposure.
  
  
  RESULTS
  Of active duty military personnel who had a past year combat deployment, 25.6% were frequent binge drinkers and 13.9% reported experiencing a TBI on the deployment, primarily TBI-AC (7.5%). In regression models adjusting for demographics and positive screen for posttraumatic stress disorder, active duty military personnel with TBI had increased odds of frequent binge drinking compared with those with no injury exposure or without TBI: TBI-AC (adjusted odds ratio, 1.48; 95% confidence interval, 1.18-1.84); TBI-LOC 1+ (adjusted odds ratio, 1.67; 95% confidence interval, 1.00-2.79).
  
  
  CONCLUSIONS
  Traumatic brain injury was significantly associated with past month frequent binge drinking after controlling for posttraumatic stress disorder, combat exposure, and other covariates.
