How sedentary are Canadian adults? It depends on the measure

Canadian adults spend a large proportion of their day engaged in sedentary behaviour, which in excess, is a risk factor for hypertension, obesity, depression, chronic conditions and premature mortality. Using data from the Canadian Health Measures Survey (CHMS) and the new Canadian 24-Hour Movement Guidelines for Adults aged 18-64 years and 65 years and older, the purpose of this study is to compare the percentages of Canadians meeting three different sedentary thresholds (less than and equal to 3 hours per day of screen time, less than and equal to 7 per day of self-reported sitting time and less than and equal to 9 hours per day of accelerometer-measured sedentary time).
