Community engagement in public health: a bibliometric mapping of global research

Background: Community engagement (CE) has been regarded as a critical element of successful health programs to achieve "the health for all" goals. Numerous studies have shown that it plays a significant role in reducing inequalities, improving social justice, enhancing benefits, and sharing responsibility towards public health. Despite this, the extant literature of community engagement in public health (CEPH) has topic-focused boundaries and is scattered across disciplinary. Large-scale studies are needed to systematically identify current status, hotspots, knowledge structure, dynamic trends, and future developments in this field. Methods: The bibliometric techniques were applied in the analysis of publications on CEPH in Web of Science Core Collection from Thomson Reuters. One thousand one hundred two papers out of 70.8 million publications over the period of 1980 to 2020 and their 15,116 references were retrieved as the sample set. First, basic characteristics of publications, including distributions of geography, journals and categories, productive authors and frequently cited articles, etc. were obtained. Then, four bibliometric methods, i.e. social network analysis, co-citation analysis, co-occurrence clustering, and burst detection, were further conducted to sketch the contours of the structure and evolution of CEPH. Results: Between Jan 1, 1980, and Apr 25, 2020, CEPH has attracted a sharp increase in interest all over the world. Total 117 countries or regions have participated in the field of CEPH and the contributions are geographically and institutionally distinct. The United States is the key region performing such research, which accounts for more than half of the total number of publications. Developing countries, such as South Africa, India, Brazil and China also contributed a lot. The advancements of CEPH are marked by historically momentous public health events and evolved from macroscopic strategies to mesoscopic and microscopic actions. Based on keyword clustering and co-citation clustering, we propose a 4O (i.e. orientation, object, operation, and outcome) framework of CEPH to facilitate a better understanding of the current global achievements and an elaborate structuring of developments in the future. Conclusion: This study draws an outline of the global review on the contemporary and cross-disciplinary research of CEPH which might present an opportunity to take stock and understand the march of knowledge as well as the logical venation underlying research activities which are fundamental to inform policy making.
