The internet has become a preferred source for people seeking health information, including diet recommendations which are pivotal in the management of inflammatory bowel disease (IBD). Hence, we aimed to assess the quality of online information in China regarding IBD dietary recommendations.
The search engines Baidu and Bing were used to screen for their top 25 webpages using the keywords "inflammatory bowel disease diet," "ulcerative colitis diet," "Crohn's disease diet," "inflammatory bowel disease nutrition," "ulcerative colitis nutrition," and "Crohn's disease nutrition." The quality of information was assessed by two physicians according to the Journal of the American Medical Association (JAMA) benchmark, the Global Quality Score (GQS), and the DISCERN instrument.
One hundred and eight webpages were selected for evaluation. The mean scores for JAMA, GQS, and DISCERN were 1.48, 3.11, and 36.20, respectively. Articles from professionals and non-profit organizations demonstrated superior quality compared to those from commercial and health portal websites. Many webpages failed to provide an explicit source of information or support for shared decision-making. The information on several pages lacked comprehensive descriptions of food types for IBD, with some pages even containing inaccuracies. No statistically significant differences in scores were observed between Baidu and Bing.
The quality of online information on IBD dietary recommendations in China is moderate to low and exhibits significant variation across different sources. This warrants joint efforts from online authors, internet platforms, and regulators, to improve the quality of popular medical information.
互联网已成为人们获取健康信息的首选来源，包括在炎症性肠病（IBD）管理中起关键作用的饮食建议。因此，我们旨在评估中国关于IBD饮食建议的在线信息质量。
使用搜索引擎百度和必应，通过关键词“炎症性肠病饮食”、“溃疡性结肠炎饮食”、“克罗恩病饮食”、“炎症性肠病营养”、“溃疡性结肠炎营养”和“克罗恩病营养”筛选出其前25个网页。由两名医生根据《美国医学会杂志》（JAMA）基准、全球质量评分（GQS）和DISCERN工具对信息质量进行评估。
共选择108个网页进行评估。JAMA、GQS和DISCERN的平均得分分别为1.48、3.11和36.20。与商业和健康门户网站的文章相比，专业人士和非营利组织的文章质量更高。许多网页未能提供明确的信息来源或对共同决策的支持。几个页面上的信息缺乏对IBD食物类型的全面描述，有些页面甚至存在不准确之处。百度和必应之间的得分没有统计学上的显著差异。
中国关于IBD饮食建议的在线信息质量中等偏低，且不同来源之间存在显著差异。这需要在线作者、互联网平台和监管机构共同努力，以提高大众医学信息的质量。
