Title: Advancing the measurement of sedentary behavior
Summary: The new physical activity guidelines of the World Health Organization recommend that «all adults limit the amount of time spent being sedentary», because «high amounts of sedentary behaviour are associated with diabetes, cardiovascular disease, and mortality». However, the evidence relied on by the WHO is based on measuring inactivity and not sedentary behaviour. For this reason, we developed and used new methods to simultaneously measure both components of sedentary behaviour – inactivity and sitting. Our results showed that office workers, prone to be among the most sedentary people, spend about 60% of the wake-time sitting and 55% of the wake-time inactive, but only 45% of the wake-time sedentary. The reason for the difference is that they accumulate 2 hours a day of active sitting and inactive standing, time that was previously ignored by the sedentary research field.
