This study used community-based cohort data to explore the trajectory stability (tracking coefficient or stability coefficient) and its influencing factors on the longitudinal age-related change in physical performance among older populations. An integrated statistical method with generalized estimating equations was applied to study trajectory stability… CONTINUE READING
