Abstract

OBJECTIVE:

To investigate associations of lifetime traumatic brain injury (LT-TBI) prior to an index deployment, and/or deployment-acquired TBI (DA-TBI), with postdeployment binge and heavy drinking.

SETTING:

Soldiers from 3 Brigade Combat Teams deployed to Afghanistan in 2012.

PARTICIPANTS:

A total of 4645 soldiers who participated in the Army STARRS Pre/Post Deployment Study and completed 4 assessments: T0 (1-2 months predeployment), T1 (upon return to United States), T2 (3 months postdeployment), and T3 (9 months postdeployment).

DESIGN:

Prospective, longitudinal study controlling for baseline binge drinking.

MAIN MEASURES:

Self-reported past month binge drinking (5+ alcoholic beverages on the same day) and past month heavy drinking (binge drinking at least weekly) at T2 and T3.

RESULTS:

In total, 34.3% screened positive for LT-TBI, and 19.2% screened positive for DA-TBI. At T2 only, LT-TBI, but not DA-TBI, was associated with increased odds of binge drinking (adjusted odds ratio [AOR] = 1.39, 95% confidence interval [CI]: 1.20-1.60, P < .001) and heavy drinking (AOR = 1.28, 95% CI: 1.09-1.49, P = .007). Among the subgroup with LT-TBI, also having DA-TBI was associated with increased risk of heavy drinking at T3 (AOR = 1.42, 95% CI: 1.03-1.95, P = .047).

CONCLUSION:

Routine screening for LT-TBI may help target efforts to prevent alcohol misuse among military members.
