Self\u2010reported mobility difficulty was assessed according to a question about ability to walk 1\u00a0km; this response was dichotomized into any versus no self\u2010reported difficulty walking 1\u00a0km (reference no difficulty). The age\u2010 (5\u2010year groups) and sex\u2010specific probability of self\u2010reporting difficulty walking 1\u00a0km was estimated in those with a measured slow walk using logistic regression.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Between 42% and 76% of people aged 65 and older reported any difficulty walking 1\u00a0km. Average walking speed was slowest in Russia (0.61\u00a0m\/s) and fastest in China (0.88\u00a0m\/s). The probabilities of reporting any difficulty walking 1\u00a0km in women aged 65 to 69, for example, with a slow walk varied (China\u00a0=\u00a00.35, India\u00a0=\u00a00.90, Russia\u00a0=\u00a00.68, South Africa\u00a0=\u00a00.81, Ghana\u00a0=\u00a00.91, Mexico\u00a0=\u00a00.73; test of country differences\n P<\/jats:italic>\n \u00a0<\u00a0.001). There was significant variation at older ages, albeit smaller in magnitude. Patterns were similar for men.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n Although correspondence between an objective and self\u2010reported measure of mobility was generally high, correspondence differed significantly between\n LMIC<\/jats:styled-content>\n s.
