Moderate or severe disability (6–18)	7 (2 %)
Body Mass Index: Overweight/obese (≥25 kg/m²)	200 (67 %)
Accelerometry data (mean (sd) of adjusted data³):
Baseline step count per day	7347 (2839)
Total weekly minutes of moderate or vigorous physical activity (MVPA) in bouts of at least 10 min	92 (108)

¹10 subjects were 75 years at randomisation, due to delays between invitation to participate and randomisation
²Full references for General Health, Chronic Disease Score and Townsend Disability Score, are given in the trial protocol [14]
³Accelerometry data (step counts and MVPA) were adjusted for day of the week and day order of wearing the accelerometer in a multi-level model with household and participant as random effects
