Model 1 included age and sex.
Model 2 included model 1 plus regular exercise, smoking, weekly alcohol consumption, and body mass index.
Model 3 included model 2 plus hypertension, diabetes mellitus, hypercholesterolemia, low HDL cholesterol, and the type of house (own or rent: in the analysis of equivalent household expenditure only).
