摘要
[目的/意义]健康科普知识为普及健康科学知识、提高公众健康素养、整治网络虚假健康信息具有重要价值。[方法/过程]本文以好大夫在线的健康科普板块为情境,选取癌症和皮肤病类别下50407条健康科普知识样本数据,结合LDA主题模型挖掘健康科普知识的主题分布、呈现形式和发布者特征,分析用户的需求数量和评价信息,并从供需数量匹配和用户供给偏好上探究健康科普知识的供需关系。[结果/结论]结果显示,在线医疗社区健康科普知识的主题围绕特定疾病展开。有关疾病治疗、检查及技术方案、疾病研究进展和健康护理的知识供给数量多,且存在较高专业壁垒,而就诊指导及健康咨询、健康科普教育、病理知识等需求较多的知识类别未得到充足供给。同时,健康科普知识的科普性较弱,在通俗化表述、多样化呈现和实用性价值上仍有较大提升空间。本文在理论上丰富了健康科普知识和健康知识需求的相关研究,为在线医疗社区管理者和医疗健康专业人士优化健康科普知识供给提供了参考。
