Abstract:

Objective To understand the chronic comorbidity conditions and mode of the elderly in the suburbs of Shanghai City,explore the association between chronic comorbid diseases,and provide data support for chronic disease screening,prevention and control and management of chronic disease comorbidity for the elderly residents in the suburbs of Shanghai City. Methods Using the data of free health examination of the elderly over 60 years old in the outer suburbs of Shanghai City in 2024,eight chronic diseases were included,including overweight and obesity,hypertension,hyperglycemia,hyperlipidemia,coronary heart disease,stroke,chronic nephritis and high uric acid.The Apriori algorithm was used to conduct the correlation analysis of comorbidity patterns,to explore the association and strength of association between chronic diseases in the elderly population. Results Among the 18 930 subjects,the prevalence of chronic disease was 81.18% and chronic comorbidity rate was 65.36%.The prevalence of urban residents(70.24%) was higher than that of rural residents(58.29%),and the difference was statistically significant(χ2=288.259,P<0.01).The prevalence of binary comorbidity was 21.35%,and the top three were overweight and obesity and hypertension(1 025 cases,5.41%),overweight and obesity and hyperlipidemia(1 025 cases,5.41%),hypertension and coronary heart disease(837 cases,4.42%).The prevalence of ternary comorbidity was 14.57%,and the top three patients were overweight and obesity and hypertension and stroke(1 071 cases,5.66%),overweight and obesity and hyperlipemia and coronary heart disease(712 cases,3.76%),and hypertension and stroke and hyperglycemia(432 cases,2.28%).The association rule analysis showed that most of the eight chronic diseases included in this study were mostly associated with hypertension and stroke.In order of confidence,the most common binary comorbidity pattern was stroke and hypertension,and the ternary comorbidity pattern was stroke and hypertension and overweight and obesity.The association rules of the elderly population aged 60-<70 and 70-<80 were higher than those of the elderly population aged≥80. The chronic comorbidity of urban elderly residents was more complicated than that of rural elderly residents. Conclusions The situation of chronic diseases and comorbidities among elderly residents in four remote communities in Shanghai City is not optimistic. It is necessary to strengthen the comprehensive management of elderly patients with chronic diseases and comorbidities by family doctors,deepen the work of health self-management groups in various streets and towns,refine the health education and health promotion interventions for the elderly population in various medical systems within our jurisdiction,effectively enhance residents' awareness of chronic diseases and comorbidities,promote healthy behaviors among elderly residents,prolong residents healthy lifespan,and improve the quality of life of elderly patients with chronic diseases and comorbidities.
