BMJ Open: Sedentary behaviour and life expectancy

Earlier this year SBRN published a new definition of sedentary behaviour in in French and English in the journals Applied Physiology, Nutrition and MetabolismMovement & Sport Sciences – Science & Motricité and the African Journal for Physical, Health Education, Recreation and Dance.

Although the APNM and AJPHERD versions have been online for a month or so, due to differences in publishing schedules the Movement & Sport Sciences issue was published online this past week.  It can be found here.

Here is the definition of sedentary behaviour, as proposed by the SBRN membership:

We suggest that journals formally define sedentary behaviour as any waking behaviour characterized by an energy expenditure ≤1.5 METs while in a sitting or reclining posture. In contrast, we suggest that authors use the term “inactive” to describe those who are performing insufficient amounts of MVPA (i.e., not meeting specified physical activity guidelines).

Nous suggérons que les revues définissent de façon formelle le comportement sédentaire comme une situation d’éveil caractérisée par une dépense énergétique ≤1,5 METs en position assise ou allongée.En revanche, nous suggérons que les auteurs utilisent le terme « inactif » pour décrire les individus ayant un niveau insuffisant d’activité physique d’intensité modérée à intense (MVPA), c’est-à-dire, n’atteignant pas le seuil d’activité physique recommandé.
