Abstract:
Objective:Based on the functional classification structure of the International Classification of Functioning, Disability and Health′s rehabilitation set (ICF-RS), the data available in the open database of the China Health and Retirement Longitudinal Study (CHARLS) were analyzed longitudinally to construct the development trajectories of different functional dimensions among China′s elderly population.Methods:The CHARLS data for 2013, 2015 and 2018 describing persons aged 60 and older were distributed using the ICF-RS′s classification structure. Group-based multi-trajectory modeling (GBMTM) was then applied to analyze the characteristics of the development trajectories of physical functioning, daily activities and social participation.Results:Different development trajectory subtypes emerged from the data. A gradual decline in physical functioning was evident throughout the study period, while daily activities first improved and then declined. Social participation was in decline throughout the period. There were, however, significant differences in the initial functional level, the degree of decline and the degree of decline reversal among the different subtype groups.Conclusions:The overall functional performance of the elderly in China shows a downward trend, but some functional dimensions can still improve with time, at least during the specific period covered in this open database. It is recommended that the ICF-RS be integrated into the CHARLS to comprehensively assess the classification of function and developmental changes among China′s elderly.
