Objective: To understand the prevalence and disease burden of major chronic diseases in the elderly in China and provide scientific basis for the prevention and control of chronic diseases and for the rational allocation of health resources. Methods: We analyzed the prevalence of chronic diseases in residents aged ≥60 years in China by using national and provincial surveillance data of chronic diseases and related risk factors in China. We conducted the analysis on the burden of chronic diseases in the elderly in China by using the data of global burden of disease. Results: The prevalence rates of hypertension, diabetes and hypercholesterolemia were 58.3%, 19.4% and 10.5% respectively in residents aged ≥60 years in China. Up to 75.8% of the residents aged ≥60 years had at least one chronic disease. The prevalence rate was higher in women than in men, higher in urban area than in rural area. With the increase of age, the prevalence rate of chronic diseases also increased. The top three chronic diseases with heavy disease burden in residents aged ≥70 years were stroke, myocardial infarction, cancer and chronic obstructive pulmonary disease. Conclusion: The prevalence of major chronic diseases in the elderly is high with three quarters of the elderly suffering from at least one chronic disease, and the burden of chronic diseases is increasing.
目的： 掌握我国老年人群主要慢性病患病情况和疾病负担，为制定慢性病防控政策和合理配置卫生资源提供科学依据。 方法： 采用具有全国和省级代表性的中国慢性病及其危险因素监测数据，分析我国≥60岁居民慢性病患病情况。利用全球疾病负担研究中国数据，分析我国老年人群慢性病疾病负担。 结果： 我国≥60岁居民高血压、糖尿病、高胆固醇血症患病率分别为58.3%、19.4%和10.5%，75.8%的居民患≥1种慢性病，女性均高于男性，城市高于农村；随着年龄的增加慢性病患病率增加。≥70岁居民伤残调整寿命年构成中，心脑血管疾病（39.11%）、癌症（15.40%）、COPD（10.48%）占前3位。 结论： 老年人群主要慢性病患病率高，3/4的人患≥1种慢性病，慢性病疾病负担不断加重。.
