Reconsidering “Reconsidering the sedentary behaviour paradigm”

| February 19, 2014 | 4 Comments

Earlier this week we posted the abstract of a study concluding that sedentary behaviour may not have health effects independent of physical activity.  David Dunstan and colleagues have responded with a comment on the article, available via PLOS ONE.

From the comment:

Maher and colleagues report findings from a secondary analysis of accelerometer data collected as part of the US National Health and Nutrition Examination Survey (NHANES). They found no associations of sedentary time with cardiometabolic risk biomarkers, when controlling for a measure of “total physical activity” that was composed of time spent in both moderate- to vigorous-intensity and light-intensity physical activity (that is, all non-sedentary time), weighted by intensity (accelerometer counts). On this basis, they concluded that sedentary time may not have health effects independent of physical activity. Leaving aside legitimate concerns with interpreting null results in this fashion, a broader conclusion that might be drawn is that there is limited (or no) merit in searching for “independent” effects of behaviours that are unavoidably “interdependent”.

Both the full article and the full comment are available via PLOS ONE.

    Over the last year Desiree has been setting up
    a “classroom” where she can share the things she has learned in her adventures.
    True, gardening is not always relaxing and getting out in the garden after a winter of inactivity can put you into a world
    of hurt. Permaculture is planting natural foods in land that
    is maintained without chemicals and machines, animals grazing that land naturally and cycling natural resources back into
    earth to create sustainable environments.

  4. Bulks in the advertisers are primarily private house owners,
    letting managers and property agents. This business will likely be
    operated in the owner’s home and will be done entirely on the
    internet. I have witnessed my share of scams,
