Congratulations to HALO Director Dr. Mark Tremblay on publishing a commentary titled “How should we move for health? The case for the 24-hour movement paradigm” in the Canadian Medical Association Journal. The commentary tries to explain the differences between the new Canadian 24-hour guidelines and the new WHO physical activity and sedentary behaviour guidelines. Citation details and key points are below.

Tremblay MS, Ross R. How should we move for health? The case for the 24-hour movement paradigm. Can Med Assoc J. 2020;192(49):E1728-E1729. doi:10.1503/cmaj.202345

Key Points
  • The World Health Organization (WHO), Canada and other countries have recently released public health guidelines related to healthy movement behaviours (e.g., physical activity and sedentary behaviours).
  • Despite using similar robust approaches to guideline development, notable differences are evident between the recent WHO and Canadian guidelines.
  • In general, the WHO guideline group focused on moderate-to vigorous-intensity physical activity and sedentary behaviour, whereas the Canadian group took an integrated 24-hour movement behaviour approach, including physical activity of all intensities, sedentary behaviours, screen time and sleep behaviours.
  • The 24-hour movement guideline approach used by the Canadian guideline group will likely lead to more nuanced benchmarks for surveillance, and should result in additional research to inform future guideline revisions.
