ContextAs the baby boom generation ages, more people will be working with disabilities, but we have little information regarding how disabilities affect risk for occupational injury.ObjectiveTo test the hypothesis that work-limiting disabilities in general and hearing and visual impairments in particular are risk factors for occupational injuries.DesignRetrospective cohort study.SettingThe National Health Interview Survey (NHIS), 1985 to 1994.ParticipantsThe 459827 participants in the NHIS from 1985 to 1994 who listed "working" as their primary activity, who were not farmers, and who were between 18 and 65 years of age.Main Outcome MeasureOccupational injuries in the year preceding the interview causing a residual impairment at the time of interview.ResultsAfter adjusting for occupation, self-employment, and age, occupational injury was associated with preceding work disability (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.19-1.56); blindness (OR, 3.21; 95% CI, 1.32-7.85); deafness (OR, 2.19; 95% CI, 1.17-4.12); hearing impairment (OR,1.55; 95% CI, 1.29-1.87); upper extremity impairment (OR, 1.46; 95% CI, 1.05-2.05); and arthritis (OR, 1.34; 95% CI, 1.07-1.68). Visual impairment was not associated with a significantly increased risk (OR, 1.37; 95% CI, 0.87-2.17).ConclusionsWorkers with disabilities, especially sensory impairments, appear to have an elevated risk for occupational injury. Further research in the design and evaluation of improved workplace accommodations for workers with these disabilities is needed.
