了解中国主要慢性病研究的发展历程。检索1990—2009年周内主要慢性病研究文献，分析文献数量、期刊分布、作者、研究内容和方法及问题等。共纳入中文文献20662篇，英文文献5219篇，文献数量逐年增加。其中恶性肿瘤相关文献比例超过50．0％，慢性阻塞性肺病相关文献较少；研究方法以描述性研究为主；研究问题关注病例特征和治疗；作者来源以医疗机构为主；分析提示对慢性病的研究内容和问题分布不均，部分文献研究设计不恰当。中国慢性病研究应注重研究内容与疾病负担相结合，并根据研究的问题选择适宜研究方法。

To review the findings on major chronic diseases in Chinese literature, articles published between 1990 and 2009 were systematically collected. Bibliometric method was used to describe the research number, research topics, methods used, research problems and authors＇ affiliations. 20 662 articles in Chinese and 5219 articles in English languages were included, showing the number of research papers was increasing every year. More than half of the papers were focusing on tumors while less was on chronic obstructive pulmonary disease. Descriptive methods were often used and papers were mainly related to clinical characteristics and treatment. Most of the authors were from medical institutions. The research topics on major chronic diseases had an uneven distribution on the classification of diseases and on the problems. There was some inappropriateness on research design regarding the etiology and treatment. Topics related to disease burden and methodology called for further attention and improvement in the future.
