Application of Global Activity Limitation Indicator on Measuring Disability - China, 2019-2022

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: As a one-item survey instrument, the global activity limitation indicator (GALI) is simpler and easier to measure disability than traditional instruments. The reliability of GALI has been proven in different regions, though it is affected by cultural differences. WHAT IS ADDED BY THIS REPORT?: This study systematically evaluates the applicability of GALI in China using a nationally representative survey. GALI demonstrates a high response rate and is significantly associated with traditional disability instruments, illness, and depression. At the county level, GALI is positively associated with mortality, while negatively associated with the number of physicians per thousand residents. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: GALI could serve as a reliable measure of disability for the population of the Chinese mainland. The results suggest that a higher number of physicians per thousand residents is associated with reduced activity limitation. Additional evidence is needed to validate this association.
