  1. Continuous variables summarised as median ± inter-quartile range; categorical variables as %. MoCA - Montreal Cognitive Assessment. MMSE - Mini-mental State Examination. BMI - body mass index. Timed up-and-go: time taken to rise from chair, walk 3 metres, and return to seat. Chair stands: time taken to repeat five stands from seated position, without assistance of arms; adata available for n = 395. Falls: any fall in the previous year. CHR: non-cardiac chronic conditions ordered count - none, one, two or more. CHR includes: cataracts, glaucoma, age-related macular degeneration, lung disease, asthma, arthritis, osteoporosis, cancer, substance abuse, ulcer, varicose ulcer, liver disease, thyroid condition, kidney disease, anaemia. CES-D quartiles: based on CES-D short form; bdata available for n = 432. Cardiac disease history: presence of at least one of abnormal heart rhythm, angina, cardiac arrest, or heart attack. Self-reported variables: gender, education, falls, CHR, cardiac disease history, smoking history; all other variables measured.
