Sedentary behaviour can be inferred by asking about the following:
- TV use
- Computer Use/Video Games
- Screen Time
- Telephone Use
- Sitting Socialising with Friends
- Listening to Music
Large scale surveys include questions about sedentary behaviour, such as, The Australian Diabetes and Lifestyle Study, International Physical Activity Questionnaire (IPAQ short & long forms), American Time Use Study, National Health and Nutrition Examination Survey, National Health Interview Survey, National Travel Survey, Highway Agency for Travel Time, Scottish Health Survey, European Prospective Investigation into Cancer, Behavioural Risk Factor, and many more….
Can also be objectively measured by use of activity monitors such as ActivCal & ActiGraph, where counts of <100/min are considered sedentary or the ActivPAL which measures the amount of time in sitting or lying postures.
What Else Can We Do?
We used an activity monitor and a body worn camera to see if it’s feasible to define the context of sedentary behaviour by using these pieces of equipment in combination. I am presenting our findings at the World Congress on Active Ageing on Thursday 16th August, hope to see you there!
