A pilot study indicated that obesity was associated with an increased time lost from work and higher costs among workers’ compensation claimants sustaining severe, but not minor injuries.
The aim of this study was to further test the hypotheses by increasing sample size and controlling for additional confounding factors.
Cost and lost time outcomes were assessed for 2301 lost time workers’ compensation claims filed in 2011 and 2012 followed to the end of the first quarter of the third postinjury year.
Adjusting for gender, age, marital status, attorney involvement, and spinal procedures, the odds ratios of incurring a claim expense at least $100,000 after a severe injury for an overweight or obese versus normal weight claimant was 2.11 [95% confidence interval (95% CI): 1.04 to 4.29] and 2.23 (95% CI:1.12–4.46), respectively.
