摘要: 目的 通过对高血压相关网络大数据舆情的分析,了解新闻媒体和自媒体对高血压关注的程度和焦点,为我国慢性非传染性疾病的防控和宣传教育提供依据。方法 利用计算机网络爬虫和深度挖掘技术所构建的全球健康信息平台,收集2016年1月1日~2016年12月31日国内15 000余个网络媒体中高血压相关的舆情数据。应用文献计量法,词频分析法和内容分析法进行高血压热点分析。结果 获取关于高血压的有效题录为2 611 251条。结果发现:高血压关注热度与发病季节、重大事件和区域发展水平等因素相关;高血压舆情侧重于饮食、营养、临床治疗等方面;世界卫生组织提出的慢性非传染性疾病的危险因素,如:吸烟,酗酒等均未出现在前60位热词中。结论 网络舆情对于高血压的宣传教育不足,建议我国以后的舆情导向应更强调慢性病的一级预防。有效利用网络数据来提高全民健康素养,对促进我国健康事业发展和非传染性疾病的防控有重要意义。Abstract: Objective Based on the public opinions from internet big data about hypertension, the aim of this study was to analyze public focus and attention in order to provide evidence for the prevention strategies and propagate education of chronic non-communicable diseases in China.Methods The Global Health Information Platform was created by using web crawler and deep mining technology, which collected public opinions from more than 15 000 news media and social media websites.
