Study on the Chronic Disease Comorbidities Pattern and the Distribution of Catastrophic Health Expenditure among the Elderly in China
Objective:Clarifying the comorbidity patterns of chronic disease and its distribution of catastrophic health expenditure in the elderly,in order to provide scientific data support for the development of chronic disease management strategies in various regions.Methods:Data were selected from China Health and Retirement Survey.Latent class model and Geoda were used to analyze the mode of chronic disease comorbidities in the elderly and the spatial distribution of catastrophic health expenditures.Results:The comorbidity pattems of chronic diseases in the elderly included circulatory and metabolic diseases,digestive disease,skeletal diseases,respiratory diseases,tumors,digestive and psychiatric diseases,and multisystem diseases.The incidence of catastrophic health expenditure with chronic disease comorbidities was 30.12％,and Moran's I value was 0.854(P＜0.05),indicating spatial autocorrelation.Qinghai,Inner Mongolia and Tianjin etc.were high-high areas,while Liaoning,Jilin and Zhejiang etc.were low-low areas.Conclusion:The occurrence of catastrophic health expenditures was characterized by sociodemographic differences and regional and comorbidity pattems of inequality.It is suggested that we should pay more attention to the management of chronic diseases,dynamically adjust the old-age chronic disease insurance policy and explore medical security system with a comorbidity model.
