To compare (1) the quality of prostate cancer health information on the Internet, (2) the difference in quality between websites appearing earlier or later in the search, and (3) the sources of sponsorship for each of these websites.
The top 150 listed websites on the Google search engine for each of the 11 search terms related to prostate cancer were analysed. Quality was assessed on whether the website conforms to the principles of the Health On the Net Foundation. Each of these websites was then reviewed to determine the main source of sponsorship. Statistical analysis was performed to determine if the proportion of HON accreditation varied among the different cohorts of listed websites and among the 11 search terms used.
In total, 1650 websites were analysed. Among these, 10.5% websites were HON-accredited. The proportion of HON-accredited websites for individual search terms ranged from 3.3% to 19.3%. In comparison with the search term of "Prostate cancer," four search terms had statistically significant odds ratio of the rate of HON accreditation. Websites 51-150 were statistically less likely to have HON accreditation than websites 1-50. The top three website sponsors were journal/universities (28.8%), commercial (28.1%), and physician/surgeon (26.9%).
The lack of validated and unbiased websites for prostate cancer is concerning especially with increasing use of the Internet for health information. Websites sponsored or managed by the government and national departments were most likely to provide impartial health information for prostate cancer. We need to help our patients identify valid and unbiased online health resources.
比较（1）互联网上前列腺癌健康信息的质量，（2）搜索结果中靠前或靠后出现的网站在质量上的差异，以及（3）这些网站各自的赞助来源。
对谷歌搜索引擎上与前列腺癌相关的11个搜索词各自列出的前150个网站进行分析。根据网站是否符合健康上网基金会的原则来评估质量。然后对每个网站进行审查以确定主要赞助来源。进行统计分析以确定健康上网基金会认证比例在列出网站的不同群组之间以及所使用的11个搜索词之间是否存在差异。
总共分析了1650个网站。其中，10.5%的网站获得了健康上网基金会的认证。各个搜索词的健康上网基金会认证网站比例在3.3%至19.3%之间。与“前列腺癌”这个搜索词相比，有四个搜索词的健康上网基金会认证率的优势比具有统计学意义。排名51 - 150的网站获得健康上网基金会认证的可能性在统计学上低于排名1 - 50的网站。排名前三的网站赞助方是期刊/大学（28.8%）、商业机构（28.1%）和内科医生/外科医生（26.9%）。
尤其是随着互联网在健康信息方面的使用日益增加，缺乏经过验证且无偏见的前列腺癌相关网站令人担忧。由政府和国家部门赞助或管理的网站最有可能提供关于前列腺癌的公正健康信息。我们需要帮助我们的患者识别有效的、无偏见的在线健康资源。
