We considered respondents to be up to date for colorectal cancer screening if they had FOBT in the previous 2 years or colonoscopy or sigmoidoscopy in the previous 5 years.
About 9% of the total sample (n = 4600, weighted n = 1 081 161) were excluded from the models owing to missing data across variables. The models included 4300 respondents (weighted n = 997 495). Adjusted models are simultaneously adjusted for every other variable included in the model. We did not include the mammogram variable to enable comparisons across males and females.
Body mass index was calculated based on the international standard.24
Physical activity was defined based on Canadian physical activity guidelines. 25
