This bibliometric study analyzed eating disorder research from 1975 to 2024, examining publication trends, research themes, and the relationship between public engagement and academic attention over five decades.
Data were collected from PubMed, Web of Science, APA PsycInfo, and CINAHL. Publication trends were analyzed, and leading journals were identified. Network analysis using VOSviewer identified thematic clusters, while a bump chart visualized changes in key research terms over time. Trends, associations, and influencing factors of public engagement and academic attention were assessed using Altmetric Attention Scores per Year (AASPY) and citations per year (CPY).
A total of 101,993 publications were analyzed. Research output increased significantly, with the International Journal of Eating Disorders as the leading contributor. Six major research clusters were identified, and eight key terms (humans, female, anorexia nervosa, adult, adolescent, male, feeding and eating disorders, and child) remained dominant across all decades. AASPY and CPY increased over time but showed a weak correlation (R = 9.09%), suggesting that digital engagement was not strongly associated with scholarly attention. Studies on young adults and those published in multidisciplinary journals had higher online engagement, while research on female and young adult populations, as well as neuroscience, received greater academic attention.
The findings highlight the sustained growth of research output, the persistence of core thematic areas, and the divergence between public engagement and academic attention. By examining trends from past to present, this study provides a basis for understanding research developments and their implications for future directions in eating disorder research.
这项文献计量学研究分析了1975年至2024年的饮食失调研究，考察了五十年来的出版趋势、研究主题以及公众参与度与学术关注度之间的关系。
数据收集自PubMed、科学网、美国心理学会心理学文摘数据库和护理学与健康领域数据库。分析出版趋势并确定主要期刊。使用VOSviewer进行网络分析以识别主题聚类，而凹凸图则直观展示关键研究术语随时间的变化。使用每年的Altmetric关注度得分（AASPY）和每年的被引频次（CPY）评估公众参与度和学术关注度的趋势、关联及影响因素。
共分析了101,993篇出版物。研究产出显著增加，《国际饮食失调杂志》是主要贡献者。确定了六个主要研究聚类，八个关键术语（人类、女性、神经性厌食症、成年人、青少年、男性、进食和饮食失调、儿童）在所有十年中均占主导地位。AASPY和CPY随时间增加，但相关性较弱（R = 9.09%），表明数字参与度与学术关注度没有强烈关联。关于年轻人的研究以及发表在多学科期刊上的研究具有更高的在线参与度，而关于女性和年轻人群体以及神经科学的研究获得了更多的学术关注。
研究结果凸显了研究产出的持续增长、核心主题领域的持续性以及公众参与度与学术关注度之间的差异。通过考察过去到现在的趋势，本研究为理解饮食失调研究的发展及其对未来方向的影响提供了基础。
