Objective To analyze the citation status of Chinese Journal of Geriatrics,and to evaluate the authority and quality of this journal.Methods Literatures including original research articles,short reports of original studies,reviews and clinical case reports etc.from 2003 to 2007 were collected from China national knowledge internet (CNKI) and Wanfang Database.The citation frequency,author distributions,relevant journals and foundation status were statistically analyzed.Results Totally 1649 papers were published in Chinese Journal of Geriatrics from 2003 to 2007,among which 1280 papers were cited 9062 times by 946 kinds of journals,the average citation times was 7.08 times,and the top citation times was 131 times.270 articles were cited 10 or more times (21.09％).The top 3 relevant journals with high citations from Chinese Journal of Geriatrics were Chinese Journal of Gerontology,Chinese Journal of Geriatrics and Chinese Journal of Misdiagnostics (totally 591 times,6.52％).The self-citation rate was 1.95％.445 articles were supported by different kinds of funds (totally 112 kinds),and majority of articles were supported by National Natural Science Foundation of China.Articles supported by 106 kinds of funds were cited and the total citation times was 2312 times.Conclusions Literatures in Chinese Journal of Geriatrics have high quality and authority with an amount of readers and relatively stable relevant journals.Journal quality and academic level are highly improved,but further efforts are needed to promote the coordinated development of regions.

Objective To investigate the characteristics of the author groups in 《Chinese Journal of Geriatrics》,in order to provide references for the future construction and development of the author ranks.Methods Bibliometric method was used to analyze the quantity of papers,region distributions,core authors and cooperative rate in 《Chinese Journal of Geriatrics》 from 2009 to 2013.Results The total amount of papers published in 《Chinese Journal of Geriatrics》》 from 2009 to 2013 was 1636,involving 31 provinces,autonomous regions,municipalities and administrative region.Among these,Beijing,Zhejiang,Tianjin and Jiangsu were the 3 top contributing regions,accounting for 54.0 percent (884/1636 papers).The 1636 papers were contributed by 1435 authors (first authors),of whom 1275 authors published only one paper,accounting for 87.7％ (1275/1435),and their papers accounted for 77.9％ of the total published papers (1275 /1636).27 authors had high yield of 3 or more papers published and deep influence,and they published 95 papers (5.8％).The degree of cooperation was 4.6 (7599 /1636),and the cooperation rate was 93.8％ (1534/1636) within the five years.Conclusions 《Chinese Journal of Geriatrics》is quite influential and attractive in the fields of geriatrics,and a good cooperative relationship is displayed between different authors and authors' institutions.

Objective To understand the research status and development tendency of domestic geriatrics.Methods To analyze all the key words in the academic articles from five representative Chinese journals of geriatrics from 2009 to 2013 through key words frequency analysis.Results From 2009 to 2013,the 55212 key words in 15314 articles were analyzed.The percentages of the articles indexing 3,4 and 5 keywords were 39.3％ (6012/15314),33.3％ (5092/15314) and 13.9％(2123/15314),respectively.There were 45 high-frequency keywords,among which 17 key words (37.8％) were in the top 30 every year.The main research object of geriatrics was Aged,the main research contents were common diseases in the elderly,including Diabetes Mellitus,Coronary Artery Disease,Alzheimer's Disease,Hypertension,Cerebral Infarction,Cognition Disorders and etc.The Risk Factors,Therapeutics and Prognosis of these common diseases were always explored.Co-words analysis showed that there were 51 pairs of key words with a frequency more than or equal to 20.Conclusions The hot-spot of geriatric research in our country is relatively concentrated.We should pay attention to body disease,and focus on the mental health problems in the elderly.
