健康扶贫背景下脱贫地区农村老年人慢性病共病网络分析OA

Objective To explore the comorbidity pattern of chronic diseases in the elderly population af-ter poverty alleviation,and to provide a scientific basis for chronic disease management in rural areas.Methods Using a random cluster sampling method,3117 rural elderly individuals aged 60 years or above from a poverty-free county were selected as the study subjects.Apriori association rule and Web graph were used to explore the associ-ation among chronic diseases and to analyze the comorbidity pattern in chronic diseases in the rural elderly after poverty alleviation.Results The comorbidity rate of chronic diseases among rural elderly individuals who had been lifted out of poverty was 63.23％.The prevalence of comorbidity was higher among elderly individuals who lived alone and who lived with disabilities,with rates of 71.27％and 72.64％,respectively.Among the dyadic combinations of comorbidity patterns,the highest prevalence was observed for cerebrovascular disease combined with hypertension,at 27.87％.For the ternary combinations,the highest prevalence was 9.82％,specifically for the coexistence of cerebrovascular disease,hypertension,and heart disease.All nine comorbidity rules identified for chronic diseases were related to hypertension.The comorbidity network within chronic disease patients centered around hypertension.Conclusions Elderly individuals who have been lifted out of poverty and suffer from chronic diseases have a high comorbidity rate.It is necessary to develop precise comorbidity prevention strategies according to the characteristics of this population,and to implement targeted control strategies for key chronic diseases.
