国内外身体活动研究趋势的知识图谱分析(2000—2014年)

Knowledge Map Analysis of the Physical Activity Researches at Home and Abroad(2000-2014)

研究选择Web of Science(WOS)数据库与和中国知识资源总库(CNKI数据库),检索2000—2014年收录的有关身体活动的研究文献分别为7 465篇与292篇。应用Cite SpaceⅡ软件对国内外身体活动流行病学研究文献进行知识图谱分析,探索研究的热点与前沿趋势话题。结果发现:美国、英国、加拿大、澳大利亚等西方国家的研究最为活跃,尤其是美国;在公共卫生、体育科学、医学社会科学、神经科学等学科领域的研究较多,而国内侧重于建筑环境、社会生态、锻炼心理等方面;久坐行为与健康、建筑环境与身体活动、肥胖问题是国外研究的热点话题;国外的研究目标人群主要选择青少年儿童、老年人、妇女等弱势群体,而国内重点集中于青少年儿童与学生群体。同时提出国内外在相关领域研究成果的数量与质量上均存在明显差距,应加强学科交叉与国际交流,国内学者要重视基础研究及其学科建设。

through the databases of Web of Science （WOS）and CNKI, the author retrieved 7,465 and 292 articles respectively about physical activity and health study from 2000 to 2014. The study applies CiteSpace II software to make a knowledge map analysis of the foreign and domestic research documents on physical activity epidemiology and tries to find out the hot research areas and the cutting-edge trend in the field. The result shows that the research activities are quite active in the US, UK, Canada, Australia and some other Western countries, especially the USA. Most of the researches focus on public health, sport science, medical social science and neuroscience. While in China, the researches place emphasis on building environment, social ecology, exercise psychology, etc. Sedentary behavior and health, building environment and physical activity, the problem of obesity are the hot research topics abroad. The foreign researchers usually select the vulnerable groups like children, the aged and women as the research subjects. While their domestic counterparts pay more attention to juveniles and students. The article states that there is a big gap between the researches in China and those in the world in terms of the quantity and quality of the research achievements. Therefore, interdisciplinary studies and international communication should be strengthened. The domestic researchers should pay more attention to basic studies and discipline construction.
