The number of research articles on health-related quality of life (HRQoL) has been strikingly increasing. This study aimed to explore the general trends and hotspots of HRQoL.
Based on the Web of Science database, research on HRQoL published between 2000 and 2019 were identified. A bibliometric analysis was performed based on the number of articles, citations, published journals, authors' addresses, and keywords. Descriptive analysis, visualization of geographic distribution and keyword clustering analysis were applied to the collected data.
The annual number of articles showed growth over the past twenty years, but the annual total citations and annual citations per article were both in decreasing trends. Articles about HRQoL were more likely to be published in journals of multi-subject categories. The HRQoL research was mainly distributed across North America and Europe throughout the twenty years and ushered in a vigorous development worldwide after 2015. Cooperation strength between domestic institutions was much greater than that of international institutions. HRQoL research had six concentrated clusters: HRQoL, Depression, Obesity, Disability, Oncology, Fatigue.
This study provided an overall perspective of global research trends and hotspots in HRQoL, and a potential insight for future research. HRQoL research had experienced significant increasing development during 2000-2019, especially the HRQoL measurement instruments, however, there were significant regional disparities in scientific output in HRQoL.
与健康相关的生活质量（HRQoL）的研究文章数量显著增加。本研究旨在探讨 HRQoL 的总体趋势和热点。
基于 Web of Science 数据库，确定了 2000 年至 2019 年间发表的 HRQoL 研究。根据文章数量、引文数量、发表期刊、作者地址和关键词进行了文献计量分析。对收集的数据进行了描述性分析、地理分布可视化和关键词聚类分析。
过去二十年，每年发表的文章数量呈增长趋势，但每年的总引文数和每年的引文数均呈下降趋势。关于 HRQoL 的文章更有可能发表在多学科类别的期刊上。HRQoL 研究在过去二十年主要分布在北美和欧洲，2015 年后在全球范围内迎来了蓬勃发展。国内机构之间的合作强度大于国际机构之间的合作强度。HRQoL 研究有六个集中的聚类：HRQoL、抑郁、肥胖、残疾、肿瘤学、疲劳。
本研究提供了全球 HRQoL 研究趋势和热点的整体视角，为未来的研究提供了潜在的见解。2000-2019 年期间，HRQoL 研究经历了显著的增长发展，特别是 HRQoL 测量工具，但 HRQoL 的科学产出在区域上存在显著差异。
