The Regularity in the Elder's Health Status Transition and Its Implication on Disability Prevention
Along with the expanding life expectancy,chronic diseases and disability risks increase rapidly among the elderly.This study uses the data of CHARLS 2011-2020 to construct a health status transition model,and explores the regularity in the elder's health status transition.It also tests the impact of the comprehensive prevention and control of chronic diseases on disability prevention,by taking the establishment of the Demonstration Area for Comprehensive Prevention and Control of Chronic Diseases as a quasi-natural experiment.We find a salient health status transition trajectory from healthy statas to disability via chronic diseases(and complications)in the elderly population,and chronic diseases play an important role in disability incidence for the elderly.The probability of transiting from a healthy state to having chronic diseases continues to increase as one ages,and it exceeds 50％after the age of 75.The probability of transiting from chronic disease to disability is much greater than the disability probability without chronic diseases.Therefore,it is an important pathway to prevent and control chronic diseases through life time as to prevent disability in the elderly.The comprehensive prevention and control of chronic diseases can effectively reduce the middle-aged and elderly's incidence as well as severity of disability by increasing health monitoring,improving knowledge on chronic diseases,and strengthening the chronic diseases treatment.The effect is more pronounced in the areas with fewer medical resources and lower medical service quality.The conclusive remark is made on strategies of disability prevention decision-making and health promotion in China.
