The Internet has become an important source of information about pregnancy and about health related concerns in general. This study assessed the quality of information available on the Internet for the common problem of nausea and vomiting of pregnancy (NVP).
We used three search terms, "nausea and vomiting in pregnancy," "morning sickness," and "hyperemesis gravidarum," to identify the most popular sites as rated by Google. With modifications of previously described tools, the quality of the websites was rated in three categories: accountability using the Silberg criteria, presentation using a modified Abbott's score, and readability using the Flesch-Kincaid grade level score. Subsequently the information on the websites was compared with the SOGC guideline on management of NVP.
We identified 24 unique websites as most popular. The overall scores for accountability indicated poor quality, with only 25% of the websites meeting the required criteria and less than one half of the sites indicating authorship and credentials. Esthetic appeal criteria were met in over 75% of the websites. The readability score of the websites was significantly above the score recommended for the general population, with an average Flesch-Kincaid Grade level score of 10.7 (max = 12). Eighty-seven percent of the websites contained accurate, evidence-based recommendations according to the information provided in the SOGC clinical practice guideline on management of NVP.
Overall, the majority of information available online is accurate; however, the web pages demonstrated poor accountability and targeted an audience with a higher reading ability than the general population. Consideration of these findings would help create easy to navigate, credible web pages containing information to help women make informed decisions during pregnancy.
互联网已成为有关妊娠及一般健康相关问题的重要信息来源。本研究评估了互联网上关于妊娠恶心和呕吐（NVP）这一常见问题的可用信息质量。
我们使用了三个搜索词，即“妊娠恶心和呕吐”“晨吐”以及“妊娠剧吐”，以确定谷歌评级最受欢迎的网站。通过对先前描述的工具进行修改，将网站质量分为三类进行评级：使用西尔伯格标准评估问责性，使用修改后的雅培评分评估呈现方式，使用弗莱什 - 金凯德年级水平评分评估可读性。随后，将网站上的信息与加拿大妇产科医师学会（SOGC）关于NVP管理的指南进行比较。
我们确定了24个独特的最受欢迎网站。问责性的总体得分表明质量较差，只有25%的网站符合要求标准，不到一半的网站标明了作者身份和资质。超过75%的网站符合美观吸引力标准。网站的可读性得分显著高于针对普通人群推荐的分数，平均弗莱什 - 金凯德年级水平得分为10.7（满分 = 12）。根据SOGC关于NVP管理的临床实践指南中提供的信息，87%的网站包含准确的、基于证据的建议。
总体而言，网上的大多数信息是准确的；然而，网页显示出问责性较差，并且针对的受众阅读能力高于普通人群。考虑这些发现将有助于创建易于浏览、可信的网页，其中包含有助于女性在孕期做出明智决策的信息。
