Occupational dust exposure-related chronic obstructive pulmonary disease: a bibliometric and visual analysis / 中国职业医学

ABSTRACT

OBJECTIVE: To analyze the current status and research hotspots of occupational dust exposure-related chronic obstructive pulmonary diseases(COPD). METHODS: Publications were searched and collected from the CNKI, SinoMed, PubMed and EMBASE. The high frequency key words were visually analyzed using NoteExpress V3.0 and VOSviewer 1.6.10, and content analysis was used to analyze research hotspots. RESULTS: A total of 3 095 COPD publications related to occupational dust exposure were retrieved. The first paper on COPD was published in 1973 in Chinese literature, and the number of publications had been on the rise since 2006. A total of 410 journals and 980 research institutions had published relevant articles. The first paper on COPD was published in 1950 in English literature, with a peak in publication after 2014. A total of 523 journals and 109 countries or regions had published relevant articles. The results of keyword co-occurrence analysis showed that COPD studies related to dust exposure mainly focused on epidemiology, risk factors and clinical characteristics. CONCLUSION: The number of research papers on occupational dust exposure-related COPD has been on the rise. The research papers mainly focus on epidemiology, risk factors and clinical characteristics of COPD.
