Occupational factors as predictors of limitation and healthcare utilisation
| Occupational risk factors at baseline | Limitation and utilisation at follow up | |||||
|---|---|---|---|---|---|---|
| Restricted activity | ⩾1 emergency dept visits | ⩾1 hospitalisation | ||||
| Individual exposure OR (95% CI) | Combined exposure OR (95% CI) | Individual exposure OR (95% CI) | Combined exposure OR (95% CI) | Individual exposure OR (95% CI) | Combined exposure OR (95% CI) | |
| Multivariate model includes the variables shown, as well as smoking status, age by category, gender, and race (see table 1 for variable definitions and table 3 for definition and frequencies of risk factors). In combined model, odds ratios are presented for the effect of one risk factor in the absence of the other. | ||||||
