The applicability of the global activity limitation indicator in the elderly population of China
Objective To compare other health measurement indicators and verify the effectiveness of the global activity limitation indicator(GALI)to measure activity limitations in the elderly population in China,providing a basis for promoting the application of GALI in China.Methods Using data from the 2018 Chinese longitudinal healthy longevity survey(CLHLS),logistic regression and predictive models were used to analyze the correlation between GALI and activities of daily living(ADL),instrumental activities of daily living(IADL),and physical performance test(PPT).Additionally,the study explored the association between GALI and depressive symptoms.Results The logistic regression results showed that the GALI activity was significantly associated with those who reported one or more ADL limitations(OR=13.355,95％CI:12.471-14.311),IADL limitations(OR=5.321,95％CI:5.085-5.567),and physical dysfunction as measured by PPT(OR=4.073,95％CI:3.905-4.249),respectively(all P＜0.001).Individuals with depressive symptoms were more likely to report GALI limitation(OR=2.311,95％CI:2.211-2.416,P＜0.001).Conclusions GALI proves to be an effec-tive instrument for assessing the general status of physical activity limitations among the elderly in China.And it may also reflect the impact of psychological factors,such as depressive symptoms.Thus,it has certain application prospects in China's health measurement and monitoring index system.
