Abstract：Objective To investigate the current status of chronic non-communicable diseases(referred to as chron-ic diseases)and multimorbidities among middle-aged and older adults aged 45 years and above in China.Methods Da-ta from the 2020 China Health and Retirement Longitudinal Study(CHARLS)were utilized,including 19 128 middle-aged and older adults from 27 provinces.Stata and SPSS software were employed to analyze the prevalence of 15 chronic diseases and multimorbidities.Results In 2020,the prevalence rate of chronic diseases among middle-aged and older adults in China was 80.9%,and the prevalence rate of multimorbidities was 58.2%.Statistical differences in chronic dis-ease and multimorbidity prevalence were observed across gender,age,education level,and marital status(all P<0.05).Hypertension had the highest prevalence and comorbidity rate.The most common multimorbidity combination was arthritis or rheumatism+gastric diseases or digestive system diseases[2.97%(568/19 128)].Chronic disease prevalence across provinces ranged from 68.2%(Guangdong)to 87.8%(Heilongjiang),while multimorbidity prevalence ranged from 50.3%(Fujian)to 72.9%(Inner Mongolia Autonomous Region).Conclusions The prevalence of chronic diseases and multimorbidities among middle-aged and older adults in China remains high.Chronic disease management programs must prioritize preventing and managing hypertension,arthritis or rheumatism,and gastric diseases or digestive system diseases.
