  1. aPhysical activity category is classified according to the HAPAQ and SAPAQ where possible (Devore reported exercise intensity as metabolic equivalents (METS) [37], while the study of Colberg et al. (2008) defined the intensity of aerobic activities according to exertion levels (e.g. usual exertion, usual walking pace, stair climbing) [36]
  2. bRegular exercise was defined (using the HAPAQ) as participants engaging in at least 30 min of moderate aerobic exercise 3 times a week for a minimum of 1 year
  3. SAPAQ Self-administered Physical Activity Questionnaire, HAPAQ Harvard Alumni Physical Activity Questionnaire [31], CS cross-sectional study, PS prospective study, T2D type 2 diabetes, IGT impaired glucose tolerance
