Research on a health-related event at the stage of labour and the occurrence of adverse outcomes at the school age has provided inconclusive results. Thus far, no systematic reviews have been conducted. Thus, the objective of this study is to investigate the association between hypoxia during pregnancy or delivery and the subsequent occurrence of a developmental dyslexia in school-age children.
We used a standard search strategy of electronic databases (PubMed, PsycINFO, Web of Science, EMBASE, and Cochrane Library) and handsearching. We included observational studies (cohort studies, case-control studies) that consider as an exposure the presence of hypoxia during pregnancy or delivery, and as an outcome, developmental dyslexia in school-age children. Two reviewers independently conducted the search and determined eligibility, which was not restricted by language or year of publication.
The search took place until 1 April 2023. Of the 1,336 abstracts screened, 6 were assessed for eligibility. Of the six eligible studies, no studies met the pre-specified eligibly criteria.
We were unable to assess the association between hypoxia and developmental dyslexia, as no eligible studies were found. Thus, the association between hypoxia during pregnancy or delivery and dyslexia in school-age children remains unknown.
针对分娩阶段的健康相关事件和学龄期不良结局的研究提供了不一致的结果。迄今为止，尚未进行系统评价。因此，本研究的目的是调查妊娠或分娩期间缺氧与学龄期儿童发育性阅读障碍发生之间的关联。
我们使用标准的电子数据库（PubMed、PsycINFO、Web of Science、EMBASE 和 Cochrane Library）和手工检索策略进行搜索。我们纳入了将妊娠或分娩期间缺氧作为暴露因素，将学龄期儿童发育性阅读障碍作为结局的观察性研究（队列研究、病例对照研究）。两位审查员独立进行搜索并确定了合格性，不限制语言或出版年份。
搜索截至 2023 年 4 月 1 日。在筛选出的 1336 篇摘要中，有 6 篇被评估为符合条件。在这 6 项合格研究中，没有研究符合预先规定的合格标准。
由于未发现符合条件的研究，我们无法评估缺氧与发育性阅读障碍之间的关联。因此，妊娠或分娩期间缺氧与学龄期儿童阅读障碍之间的关联尚不清楚。
