基于网络高血压热词的慢病预防策略分析

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。
