  1. a All estimates weighted according to Sampling Design (see Methods)
  2. b Models including grip strength or grip strength/LM have N = 970. Other models, N = 1,147.
  3. c Model 1: Controlled for age and height
  4. d Model 2: Controlled for age, height, fat mass, self-rated health and physical activity
  5. e Model 3: Controlled for age, height, fat mass, self-rated health and physical activity, plus maximum grip strength, the composite physical function score, or lean mass
  6. f Model 3: Controlled for age, height, fat mass, self-rated health and physical activity, plus maximum grip strength/arms LM, composite physical function score/legs LM, or lean mass index
  7. g Lean mass index models were not adjusted for height since height2 is the denominator of the outcome
