Background??China is gradually entering an ageing society and the health of the middle-aged and elderly is a growing concernwith chronic diseases such as hypertensiondiabetescoronary heart disease and stroke becoming major health threats. At the same timethe uneven distribution of health resources has led to regional differences in medical level and service quality. Objective??To explore the correlation between the prevalence of chronic diseasesregional differences in the types of diseases and health care resources among middle-aged and elderly people in China.

Multiple linear regression analysis was used to analyze the correlation between Theil index of the number of bedsnumber of health technicians practicingassistantphysiciansregistered nursesrural doctors and health workersfinancial expenditures total health expenditurenumber of health institutionshospitalsprimary care institutionsprofessional public health institutionsand the prevalence of chronic diseases in middle-aged and elderly people in each province.

Among the 14 types of chronic diseasesthere were significant differences in the prevalence of chronic lung diseaseχ2 =30.906P<0.001liver diseaseχ2 =17.871P<0.001cerebrovascular diseaseχ2 =18.313P<0.001kidney diseaseχ2 =24.383P<0.001digestive system diseasesχ2 =16.973P<0.001memory-related diseasesχ2 =6.898P=0.032and asthmaχ2 =22.055P<0.001in middle-aged and elderly people living in the easterncentral and western regions of China.

Conclusion ?Regional health management of major chronic diseases should be strengthenedthe ability of disease prevention and health management in primary care should be improvedmedical and health personnel should be strengthenedthe regional health resources allocation balance should be improvedso as to shorten the regional differences in the prevalence of chronic diseases among middle-aged and elderly people in the easterncentral and western China.
