Comparison of the Physical Activity Frequency Questionnaire (PAFQ) with accelerometry in middle-aged and elderly people: the CoLaus study
Physical activity (PA) is an important modifiable risk factor in the prevention of non- communicable diseases, including cardiovascular disease, diabetes mellitus, several types of cancer and depression [1,2]. Several methods exist for assessing PA and sedentary behaviour (SB) [3]. Self-reported measures (e.g. questionnaires) have been widely used in epidemiological studies because of their low cost and low burden to participants [4]. Nevertheless, their reliability and validity is limited by recall bias or social desirability [5,6].
