  • Age-adjusted prevalence was estimated at the overall mean age (68 years old). Predicted prevalence was estimated at the weighted mean age in each region.

  • *P<0.05, **P<0.01, ***P<0.001 for comparing prevalence of anaemia by each factor.

  • †Slow gait speed: <0.6 m/s.

  • ‡Low grip strength: <16 kg for female and <26 kg for male.

  • ADL, activities of daily living; IADL, instrumental activities of daily living.
