Separate logistic regression models were computed for employment status (not working vs. working; part-time vs. full-time; and unemployed vs. working).
For the self-report of physician diagnosis variables, 1 model was computed which included all conditions in the model, plus the covariates age, gender, and race-ethnicity. The exception to this was the sleep disorder variable because sleep disorder assessment did not occur across all NHANES cycles. Therefore, the ORs for the sleep variable is from a separate model that included sleep disorder plus the other medical conditions and covariates.
Separate models were computed for each of the laboratory-determined variables not all participants had data on all biomarkers. In each model covariates included age, gender, and race-ethnicity.
The examination-determined variables were not all collected during the same cycles; therefore, separate models were computed for each of these examination-determined medical conditions. Covariates age, gender, and race-ethnicity were included in each model.
Working is defined as working at an outside job or business within the last week; full time is defined as ≥ 35 hrs/wk; and unemployed is defined as looking for work or on a layoff.
