目的：评估6个中低收入国家(LMIC)老年人行动能力障碍自报指标与测量指标之间的一致性。对全球老龄化与成人健康研究(SAGE)进行设计横断面分析。在中国、印度、俄罗斯、南非、加纳和墨西哥进行家庭调查。参与者65岁及以上社区居住的SAGE受访者(N=12,215)。测量：根据受试者家中以正常步速进行的4米限时步行来评估客观活动能力；根据Fry Fragity标准(步行速度最低的五分之一，根据年龄和身高进行调整)来定义慢速步行速度。根据一项关于行走1公里的问题来评估自我报告的行动困难；这种反应被分为有无行走1公里困难(参考无困难)。采用Logistic回归分析方法，对慢走受试者自我报告行走1公里有困难的年龄(5岁组)和性别进行了估计。结果在65岁及以上的人群中，有42%到76%的人报告行走1公里有困难。平均步行速度俄罗斯最慢(0.61米/S)，中国最快(0.88米/S)。例如，65岁至69岁的女性慢步行走1公里的概率各不相同(中国=0.35，印度=0.9，俄罗斯=0.68，南非=0.81，加纳=0.91，墨西哥=0.73；国家差异检验P
ObjectivesTo assess the correspondence between self-reported and measured indicators of mobility disability in older adults in six low- and middle-income countries (LMICs).DesignCross-sectional analysis of Study on Global AGEing and Adult Health (SAGE).SettingHousehold surveys in China, India, Russia, South Africa, Ghana, and Mexico.ParticipantsCommunity-dwelling SAGE respondents aged 65 and older (N=12,215).MeasurementsObjective mobility was assessed according to a 4-m timed walk at normal pace conducted in the respondent's home; slow walking speed was defined according to the Fried frailty criteria (lowest quintile of walking speed, adjusted for age and height). Self-reported mobility difficulty was assessed according to a question about ability to walk 1km; this response was dichotomized into any versus no self-reported difficulty walking 1km (reference no difficulty). The age- (5-year groups) and sex-specific probability of self-reporting difficulty walking 1km was estimated in those with a measured slow walk using logistic regression.ResultsBetween 42% and 76% of people aged 65 and older reported any difficulty walking 1km. Average walking speed was slowest in Russia (0.61m/s) and fastest in China (0.88m/s). The probabilities of reporting any difficulty walking 1km in women aged 65 to 69, for example, with a slow walk varied (China=0.35, India=0.90, Russia=0.68, South Africa=0.81, Ghana=0.91, Mexico=0.73; test of country differences P
