Occupational health has been influenced by societal and industrial changes. This study aimed to clarify topic trends in occupational health research in 1990-2022.
We conducted a text-mining-adjusted bibliometric study using research titles in occupational health. Data on research titles and the years of publication were collected from 26 peer-reviewed journals on PubMed. Using morphological and correspondence analyses in text mining, we structured research topics into multiple categories and visualized the relationship between all categories and publication years. Statistical analyses were conducted using the text mining software - KH Coder 3.0.
We obtained 48 645 articles containing 714 890 words in their titles. The research topics were classified into 4 categories and 17 subcategories, of which those of occupations; countries; non-intervention; psychosocial factors; lifestyle factors; safety; symptoms; therapy and care; and productivity have recently shown an increasing trend. In contrast, the subcategories of risk, chemical factors, disease, and organ damage showed decreasing trends. Chemical factors, which were the main topics in the 1990s, included risk, organ damage, and disease. Productivity, the main topic in the 2020s, co-occurred with lifestyle factors, symptoms, and intervention.
Focal areas in occupational-health research shift according to societal trends. Occupational-health research has primarily analyzed issues in developed countries with capitalist values and may not have sufficiently covered issues in developing countries. It is imperative for policymakers and public funding bodies to determine priorities for investigation in the field.
职业健康受到社会和工业变化的影响。本研究旨在阐明 1990-2022 年职业健康研究的主题趋势。
我们使用职业健康研究的研究标题进行了文本挖掘调整的文献计量研究。从 PubMed 上的 26 种同行评议期刊中收集了有关研究标题和出版年份的数据。使用文本挖掘中的形态和对应分析，我们将研究主题分为多个类别，并可视化了所有类别与出版年份之间的关系。使用文本挖掘软件 KH Coder 3.0 进行了统计分析。
我们获得了包含 714890 个单词的 48645 篇文章。研究主题分为 4 类和 17 个亚类，其中职业、国家、非干预、心理社会因素、生活方式因素、安全、症状、治疗和护理以及生产力等领域最近呈上升趋势。相比之下，风险、化学因素、疾病和器官损伤等亚类呈下降趋势。化学因素是 90 年代的主要主题，包括风险、器官损伤和疾病。生产力是 2020 年代的主要主题，与生活方式因素、症状和干预同时出现。
职业健康研究的重点领域根据社会趋势而变化。职业健康研究主要分析了具有资本主义价值观的发达国家的问题，可能没有充分涵盖发展中国家的问题。政策制定者和公共资助机构必须确定该领域调查的优先事项。
