Values are presented as mean (SD). PAL: physical activity level; MET: metabolic equivalent; TEEACC: total energy expenditure per day as assessed by accelerometry; TSA>3METs: time spend per day in activities demanding more than 3 metabolic equivalents; steps/day: number of steps per day; TEEZPAQ: total energy expenditure per day as assessed by the Zutphen Physical Activity Questionnaire.
