The interest in obesity has considerably increased in the scientific community in the last 2 decades. We present a bibliometric analysis to find out the future research hotspot and trends of obesity.
Data were based on the Science Citation Index Expanded (SCI-E), from the Institute of Scientific Information Web of Science database and the 5-year impact factor of a journal were issued from the Journal Citation Reports (JCR) in 2017. Articles referring to obesity during 1999 to 2017 were concentrated on the analysis by scientific output characters and the frequency of author keywords used.
Globally, 50,246 articles meet the inclusion criteria during 1999 to 2017. The cumulative number of publication about obesity followed exponential distribution (R = 0.9974) from 2008. USA was the most productive countries in both independent and international collaborative papers, the countries/regions with the highest average Times Cited scores for independent articles was France and The United Kingdom scored the highest in average Times Cited for international collaborative papers. Collaboration among countries, playing an ever-growing role in contemporary scientific research. The 2 most prolific journals are Obesity Surgery and International Journal of Obesity, responsible for 3.95% of the publication.
Obesity has been a field of intense research in the last 19 years. By reasonably analyzing the author keywords and the distribution of journals, "bariatric surgery" (especially "sleeve gastrectomy") and "obese complications" (especially "diabetes mellitus," "metabolic syndrome," "depression," and "polycystic ovary syndrome") will undoubtedly maintain the hotspots of obesity research in the next few decades.
在过去20年里，科学界对肥胖的关注显著增加。我们进行了一项文献计量分析，以找出肥胖研究的未来热点和趋势。
数据基于科学引文索引扩展版（SCI-E），来自科学信息研究所的科学网数据库，期刊的5年影响因子来自2017年的《期刊引证报告》（JCR）。对1999年至2017年期间提及肥胖的文章，按科学产出特征和作者关键词使用频率进行集中分析。
在全球范围内，1999年至2017年期间有50246篇文章符合纳入标准。自2008年以来，关于肥胖的出版物累计数量呈指数分布（R = 0.9974）。美国在独立论文和国际合作论文方面都是产出最多的国家，独立文章平均被引次数最高的国家/地区是法国，国际合作论文平均被引次数最高的是英国。国家间合作在当代科学研究中发挥着越来越重要的作用。发文量最高的两种期刊是《肥胖外科学》和《国际肥胖杂志》，占出版物的3.95%。
在过去19年里，肥胖一直是一个研究热点领域。通过合理分析作者关键词和期刊分布，“减重手术”（尤其是“袖状胃切除术”）和“肥胖并发症”（尤其是“糖尿病”“代谢综合征”“抑郁症”和“多囊卵巢综合征”）无疑将在未来几十年保持肥胖研究的热点。
