Disaster epidemiology has not attracted enough attention in the past few decades and still faces significant challenges. This study aimed to systematically analyze the evolving trends and research hotspots in disaster epidemiology and provide insights into disaster epidemiology. We searched the Scopus and Web of Science Core Collection (WoSCC) databases between 1985 and 2020 to identify relevant literature on disaster epidemiology. The retrieval strategies were TITLE-ABS-KEY (disaster epidemiology) and TS = (disaster AND epidemiology). Bibliometrix, VOSviewer 1.6.6 and SigmaPlot 12.5 were used to analyze the key bibliometric indicators, including trends and annual publications, the contributions of countries, institutions, journals and authors, and research hotspots. A total of 1,975 publications were included. There was an increasing trend in publications over the past 35 years. The USA was the most productive country. The most frequent institutions and journals were Fukushima Medical University and Prehospital and Disaster Medicine. Galea S made significant contributions to this field. "Epidemiology" was the highest-frequency keyword. COVID-19 was highly cited after 2019. Three research hotspots were identified: (i) the short- and long-term adverse health effects of disasters on the population; (ii) COVID-19 pandemic and emergency preparedness; and (iii) disaster management. In recent decades, the USA was a global leader in disaster epidemiology. Disaster management, the short- and long-term health effects of disasters, and the COVID-19 pandemic reflected the research focuses. Our results suggest that these directions will remain research hotspots in the future. International collaboration is also expected to widen and deepen in the field of disaster epidemiology.
在过去的几十年中，灾害流行病学并未受到足够的重视，仍然面临着重大挑战。本研究旨在系统分析灾害流行病学的演变趋势和研究热点，为灾害流行病学提供参考。
我们在 1985 年至 2020 年期间在 Scopus 和 Web of Science 核心合集（WoSCC）数据库中搜索了与灾害流行病学相关的文献。检索策略为 TITLE-ABS-KEY（灾害流行病学）和 TS =（灾害和流行病学）。使用 Bibliometrix、VOSviewer 1.6.6 和 SigmaPlot 12.5 分析了关键的文献计量指标，包括趋势和年度出版物、国家、机构、期刊和作者的贡献以及研究热点。
共纳入 1975 篇文献。在过去的 35 年中，出版物呈上升趋势。美国是最具生产力的国家。最频繁的机构和期刊是福岛医科大学和急救与灾难医学。Galea S 对这一领域做出了重大贡献。“流行病学”是出现频率最高的关键词。2019 年后，COVID-19 的引用率很高。确定了三个研究热点：（i）灾害对人群的短期和长期不良健康影响；（ii）COVID-19 大流行和应急准备；（iii）灾害管理。
近几十年来，美国在灾害流行病学领域处于全球领先地位。灾害管理、灾害的短期和长期健康影响以及 COVID-19 大流行反映了研究重点。我们的研究结果表明，这些方向将是未来的研究热点。预计灾害流行病学领域的国际合作也将扩大和深化。
