The impact of function on work status for community dwelling disabled persons with arthritis: an analysis of the National Health Interview Survey Disability Supplement

Arthritis is one of the most common diseases and a leading cause of disability in adults. Returning injured workers to work and preventing work disability is the primary mission of occupational health professionals. The purpose of this study was to identify risk factors associated with work disability and intervention strategies. This study is a retrospective cohort analysis of secondary individual level data. The data for the study were collected by the National Health Interview Survey, Disability Supplement (NHIS-D) 1995. Community dwelling disabled persons with functional limitations due to arthritic conditions were included in this analysis. A total of 286 records were available for logistic regression analysis. The outcome variable was work status, either working or not working. The significant predictors of working status were ability to lift 10 pounds (OR = 1.64), college education (OR = 0.21), age (OR = 1.03), and less than high school education (OR = 2.48). Thirty-four percent of the variance in working status was explained by the model that also included health status, difficulty standing, difficulty walking up steps, difficulty walking 1/4 mile, ethnicity, and gender. Younger disabled persons with arthritis, who have little difficulty lifting 10 pounds, and have some college education have better odds of working. Occupational health professionals need to look for ways to improve the educational status and functional lifting ability of disabled individuals with arthritis.
