Table 1 Definitions of Physical activity and sedentary behaviour variables

From: A cross-sectional study of physical activity and sedentary behaviours in a Caribbean population: combining objective and questionnaire data to guide future interventions

Variable   Definition
Physical inactivity Prevalence (%) Does not meet WHO minimum recommendations for physical activity, i.e. at least 150 min of MVPA per week accrued in bouts of at least 10 min [29]
Sedentary lifestyle Prevalence (%) Spends 8 h or more sedentary each day, excluding sleep [30]
Overestimator Prevalence (%) Perceives themselves as ‘active’ or ‘extremely active’ but does not meet WHO minimum guidelines for activity according to objective estimate
Physical activity energy expenditure (PAEE) (kJ/kg/day) The modifiable component of daily total energy expenditure derived from all activities
Sedentary time (hours/day) Time spent at ≤1.5 MET [29]
Light physical activity (LPA) (hours/day) Time spent between 1.5 and 3 MET [29]
Moderate-to-vigorous physical activity (MVPA) (mins/day) Time spent at ≥3 MET [29]
