People may utilize various sources when searching for health information, including blogs. This study sought to describe the nature of non-personal journal health and medical blog posts and the frequency of interactive blog feature use within these blogs, as well as to understand the quality of content found within health and medical blogs as determined by blogger expertise and blog host. A quantitative content analysis was performed on 398 blog posts from a constructed 1-week sample of posts in WebMD, Yahoo!Health Expert Blogs, and independently hosted blogs. Results show most health and medical blog posts highlighted and provided commentary pertaining to medical issues found in external media such as books, television, Web sites, magazines, and newspapers, whereas only 16% contained actual health or medical information. In addition, distinct differences in patterns of content were evident between credentialed and noncredentialed bloggers, as well as different blog hosts.
人们在搜索健康信息时可能会利用各种资源，包括博客。本研究旨在描述非个人期刊健康和医学博客文章的性质，以及这些博客中互动博客功能的使用频率，并了解健康和医学博客中内容的质量，这些质量由博主的专业知识和博客主持人决定。对 398 篇博客文章进行了定量内容分析，这些文章是从 WebMD、雅虎健康专家博客和独立托管的博客中抽取的一周样本中的帖子。结果表明，大多数健康和医学博客文章突出并评论了外部媒体（如书籍、电视、网站、杂志和报纸）中发现的医学问题，而只有 16%的文章包含实际的健康或医学信息。此外，有资质和无资质的博主以及不同的博客主持人之间的内容模式存在明显差异。
