*Adjustment variables: baseline covariates (degrees of freedom): age (1), gender (1), race (3), BMI (1), cigarette status (never, former, current) (2), environmental tobacco smoke exposure (1), per cent dietary protein (1) and interaction terms between time (years) and PM10 exposure.
†Population: the full sample (n = 3901) had exposure estimated using the nearest monitor, regardless of distance from reported residential address. 2611 participants lived within 10 km of a monitor; 2497 had examination 3 data.
