Model 1: adjusted for age and sex.
Model 2: additionally adjusted for BMI (kg/m2), diastolic blood pressure (mmHg), systolic blood pressure (mmHg), hypertension treatment (0 = no, 1 = yes), total cholesterol (mmHg), HDL cholesterol (mmHg), social class (1 = non-manual, 2 = manual), employment (0 = no, 1 = yes), and occupational physical activity (MJ/week, quartiles).
