Criterion validity of two physical activity and one sedentary time questionnaire against accelerometry in a large cohort of adults and older adults
ObjectivesWe compared the ability of physical activity and sitting time questionnaires (PAQ) for ranking individuals versus continuous volume calculations (physical activity level (PAL), metabolic equivalents of task (MET), sitting hours) against accelerometry measured physical activity as our crite...
