Knowledge mapping analysis of the relationship between obesity and cancer

目的 肥胖已经成为诱发癌症的重要危险因素,本研究利用知识图谱分析技术探索该领域的研究热点和知识基础来源,为相关人员科学研究及政策制定提供参考。方法 本文利用可视化软件CiteSpaceⅢ对Web of Science V5.13及Medline数据库中检索到的以（obesity OR obese OR fat OR overweight）AND（cancer OR tumour OR tumor OR carcinoma OR neoplasm）为检索式,时间区间为2006年1月1日~2015年12月31日之间的33296篇文献的信息进行研究。结果 通过知识图谱分析,了解到近10年该领域的研究热点和知识基础来源,研究热点就是出现频次较高的关键词,知识基础来源就是共被引频次较高的参考文献。结论 与肥胖相关癌症主要有乳腺癌、结肠直肠癌、肝癌、结肠癌、前列腺癌、子宫内膜癌等。

Objective Obesity has become an important risk factor for cancer, the technology of analysis of knowl- edge mapping was used to explore the research hot spots and basic knowledge in this field, so as to provide reference for scientific research and policy formulation. Methods Visualizing technology-CiteSpace Ill was used to analyze and show the result of 33296 articles which were extracted from Web of Science and Medline, The retrieve terms were （ obesity OR obese OR fat OR overweight） AND （cancer OR tumour OR tumor OR carcinoma OR neoplasm）. The time interval ranged from 2006 to 2015. Results According to the analysis of knowledge mapping,we observed the research hot spots and the source of basic knowledge clearly in recent 10 years, the research hot spots were the high frequencykeywords, the source of basic knowledge were high frequency co-citation references. Conclusions The cancers related to obesity are mainly breast cancer, colorectal cancer, hepatocellular carcionma, prostate-cancer, colon-cancer, endometrial cancer, etc.
