Objective To determine the prevalence of lifetime history of traumatic brain injury (TBI) with loss of consciousness (LOC) among adult, non-institutionalised residents of Ohio.

Methods We analysed data from 2014 Ohio Behavioral Risk Factor Surveillance System, which included a state-specific module designed to elicit lifetime history of TBI.

Results Of non-institutionalised adults 18 years and over living in Ohio, 21.7% reported at least one lifetime TBI with LOC, 2.6% experienced at least one moderate or severe such injury, 9.1% experienced a TBI with LOC before age 15 years and 10.8% experienced either TBI with LOC before age 15 years or a moderate or severe injury. Males, those with lower incomes and those unable to work were more likely to have incurred at least one TBI with LOC, multiple TBIs with LOC, a moderate or severe TBI and a TBI with LOC before age15.

Conclusions One in five adults experienced TBIs of sufficient severity to cause LOC; 3% experienced at least one moderate or severe TBI and almost 10% experienced a first TBI with LOC before the age of 15 years. The prevalence of lifetime TBI in the present study suggests that there may be a substantially greater burden of injury than concluded from previous prevalence estimates.
