Abstract：Objective To understand the comorbidity pattern of chronic diseases in a certain area of Sichuan,and to explore the influencing factors of chronic comorbidities in middle-aged and elderly people,so as to provide a reference for the prevention and control of comorbidities.Methods In 2023,a multi-stage stratified random sampling method was used to recruit 4521 middle-aged and elderly residents in the area for a household survey on social determinants of health for chronic diseases.The number of chronic diseases in different gender,age,marital status,educational level,occupation,drinking habits,and types of medical insurance was compared.The comorbidity pattern of chronic diseases in the area was analyzed by potential class analysis,and the influencing factors of chronic disease comorbidity were analyzed by multiple linear regression.Results A total of 4521 middle-aged and elderly people were included,of which 886 were chronic disease comorbidity patients,with a comorbidity rate of 19.60%（886/4521）.Among the non-chronic disease patients,3635 were non-chronic disease patients,Three category model was selected as the optimal model after considering the potential class analysis comprehensively.The results of multivariate linear regression analysis showed that middle-aged and elderly individuals who drink alcohol,have lost a spouse,and have urban employee medical insurance were positively associated with the co-morbidity of chronic diseases（P<0.05）,while those aged 45-59 and in employment were negatively associated with the co-morbidity of chronic diseases（P<0.05）.Conclusion The chronic disease co-morbidity pattern in the study area is mainly composed of three types of "multiple system disease type""relatively healthy type",and "cardiovascular disease type".In daily health management,attention should be paid to middle-aged and elderly individuals who drink alcohol,have lost a spouse,and have urban employee medical insurance,and targeted health management should be carried out.Reduce the incidence of chronic comorbidities.
