A compositional analysis of time spent in sleep, sedentary behaviour and physical activity with all-cause mortality risk.

ABSTRACT:

Background

Daily time spent in sleep, sedentary behaviour (SED), light intensity physical activity (LIPA), and moderate-to-vigorous intensity physical activity (MVPA) are compositional, co-dependent variables. The objectives of this study were to use compositional data analysis to: (1) examine the relationship between the movement behaviour composition (daily time spent in sleep, SED, LIPA and MVPA) and all-cause mortality risk, and (2) estimate the extent to which changing time spent in any given movement behaviour (sleep, SED, LIPA, or MVPA) within the movement behaviour composition was associated with changes in risk of all-cause mortality.

Methods

2838 adult participants from the 2005-2006 cycle of the U.S. National Health and Nutrition Examination Survey were studied us
