Accelerometer-measured moderate-to-vigorous physical activity of Canadian adults, 2007 to 2017

BACKGROUND: Surveillance of physical activity among Canadian adults has typically relied on questionnaire-based data, which have many limitations. The Canadian Health Measures Survey (CHMS) has been collecting objective, accelerometer-based physical activity data on a nationally representative sample of Canadian adults since 2007. DATA AND METHODS: ) were also calculated, and adherence to the Canadian Physical Activity Guidelines was assessed. RESULTS: per day, less than half of which (12 minutes per day, on average) was accumulated in bouts of at least 10 minutes. Average daily VPA was less than five minutes. About 3% of Canadian adults accumulated no MVPA at all, while approximately 36% did not accumulate any MVPA in bouts of at least 10 minutes; 16% of Canadian adults met the current physical activity guidelines of 150 minutes of MVPA per week in bouts of at least 10 minutes. DISCUSSION: These results may be important to governments and other organizations for initiatives geared toward increasing physical activity levels in Canadian adults.
