aSince limitations on ADL/IADL in CHARLS are based on five items, this is not comparable with the other countries (based on 6 and 7 items, respectively).
bMean values are only weighted and not age-standardized, since the test was administered at different age groups across surveys.
cCHARLS, ELSA and LASI did not administer the walking test to participants aged ≤59.
dIn ELSA have been measured in Wave 4 (2008).
eHRS did not administer the walking test to participants aged ≤64.
