Adjusted model includes age, sex, race/ethnicity, education, pay scheme (salary/hourly), employment type (full time/part time), industry (SIC code), occupation, income and company size (number of employees).
*The reference group for each HRF is a worker who did not have the HRF.
BMI, body mass index; HRF, health risk factor; WC, workers' compensation.
