Objective: To provide nationally representative prevalence estimates of
disability associated with prior head injury with loss of consciousness in
the U.S. and to examine associations between prior head injury and
disability. Methods: Cross-sectional analysis of 7,390 participants
aged ³40 years in the 2011-2014 National Health and Nutrition Examination
Surveys (NHANES). Head injury with loss of consciousness was assessed by
self-report. Domains of disability were assessed using a standardized
structured questionnaire and measured grip strength. Logistic regression
models adjusted for demographic, socioeconomic/behavioral, and medical
comorbidity variables were used. Multiple imputation was used to account
for missing covariate data. Results: Mean age of participants was 58
years, 53% were female, 71% were non-Hispanic white, and 16% had a history
of head injury. Overall, participants with a history of head injury had
higher prevalence of disability in at least one domain of functioning
compared to individuals without a history of head injury (47.4% versus
38.6%, p<0.001), with the highest prevalence of disability in the
domains of mobility and work productivity. In fully adjusted models, head
injury was significantly positively associated with disability in all
domains assessed on the standardized questionnaire (all p<0.05),
but not with upper extremity grip strength (all p>0.05).
Conclusions: 47.4% of individuals aged ≥40 years in the U.S with a history
of head injury are living with disability in at least one domain of
functioning, corresponding to approximately 11.4 million affected
individuals. This significant burden of disability suggests that efforts
are needed to improve functioning among individuals with head injury.
