Adherence
High levels of objectively measured sedentary time are associated with significantly increased all-cause mortality risk, independent of moderate-to-vigorous physical activity (MVPA).
If you are over 50, simply exercising for an hour a day may not be enough to eliminate the mortality risks associated with sitting for the rest of the day. You should actively break up long periods of sitting, regardless of your exercise routine, as prolonged sedentary time independently increases the risk of death.
Our study suggests that sedentary behavior is a risk factor for mortality independent of MVPA.
Why this rating
Large, nationally representative sample (NHANES) with objective accelerometry measurement, though follow-up is relatively short (2.8 years).
