Pregnant women actively seek health information online, including nutrition and food-related topics. However, the accuracy and readability of this information have not been evaluated. The aim of this study was to describe and evaluate pregnancy-related food and nutrition information available online. Four search engines were used to search for pregnancy-related nutrition web pages. Content analysis of web pages was performed. Web pages were assessed against the 2013 Australian Dietary Guidelines to assess accuracy. Flesch-Kincaid (F-K), Simple Measure of Gobbledygook (SMOG), Gunning Fog Index (FOG) and Flesch reading ease (FRE) formulas were used to assess readability. Data was analysed descriptively. Spearman's correlation was used to assess the relationship between web page characteristics. Kruskal-Wallis test was used to check for differences among readability and other web page characteristics. A total of 693 web pages were included. Web page types included commercial (n = 340), not-for-profit (n = 113), blogs (n = 112), government (n = 89), personal (n = 36) and educational (n = 3). The accuracy of online nutrition information varied with 39.7% of web pages containing accurate information, 22.8% containing mixed information and 37.5% containing inaccurate information. The average reading grade of all pages analysed measured by F-K, SMOG and FOG was 11.8. The mean FRE was 51.6, a 'fairly difficult to read' score. Only 0.5% of web pages were written at or below grade 6 according to F-K, SMOG and FOG. The findings suggest that accuracy of pregnancy-related nutrition information is a problem on the internet. Web page readability is generally difficult and means that the information may not be accessible to those who cannot read at a sophisticated level. © 2016 John Wiley & Sons Ltd.
孕妇会积极在网上搜索健康信息，包括营养和与食物相关的话题。然而，这些信息的准确性和可读性尚未得到评估。本研究的目的是描述和评估网上可得的与怀孕相关的食物和营养信息。使用了四个搜索引擎来搜索与怀孕相关的营养网页。对网页进行了内容分析。根据2013年澳大利亚饮食指南对网页进行评估以确定准确性。使用弗莱什-金凯德（F-K）、难词简易衡量法（SMOG）、冈宁雾度指数（FOG）和弗莱什易读性（FRE）公式来评估可读性。对数据进行了描述性分析。使用斯皮尔曼相关性来评估网页特征之间的关系。使用克鲁斯卡尔-沃利斯检验来检查可读性和其他网页特征之间的差异。共纳入693个网页。网页类型包括商业（n = 340）、非营利（n = 113）、博客（n = 112）、政府（n = 89）、个人（n = 36）和教育（n = 3）。网上营养信息的准确性各不相同，39.7%的网页包含准确信息，22.8%包含混合信息，37.5%包含不准确信息。通过F-K、SMOG和FOG测量，所有分析页面的平均阅读年级为11.8。平均FRE为51.6，属于“相当难读”的分数。根据F-K、SMOG和FOG，只有0.5%的网页写作水平在6年级及以下。研究结果表明，与怀孕相关的营养信息的准确性在互联网上是个问题。网页可读性普遍较差，这意味着那些阅读水平不高的人可能无法获取这些信息。© 2016约翰·威利父子有限公司
