The objectives of this research are to review and assess the current state of knowledge of the association between environmental temperature and gastrointestinal (GI) infections. A review of the published literature was undertaken using standard approaches. Initially, four electronic databases including Embase, Medline, Scopus, and Web of Science were chosen to retrieve studies published from 1 January 2006 to 31 December 2017 based on selected keywords used in the primary search. After the elimination of duplicates, the titles were reviewed for relevance to the principal research question. Secondly, the abstracts of titles deemed to be relevant were reviewed for significance and finally the articles were reviewed in their entirety to identify their contribution to the principal research question. Initially, 8201 articles were identified, and eight studies finally met the inclusion criteria. A secondary phase involving scrutiny of the references of key identified articles found three further studies. Consequently, 11 papers were selected for the final review. Current literature confirms a significant association between temperature and infectious gastroenteritis worldwide. Also, a most-likely non-linear correlation between rainfall and GI infections has been identified in that the rate of such infections can be increased with either high or low precipitation. Finally, some studies suggest high relative humidity may not increase the rate of GI infections and some have found it may decrease it. These findings help inform predictions of risk, particularly under future climate change scenarios.
本研究旨在回顾和评估环境温度与胃肠道（GI）感染之间关联的现有知识状况。采用标准方法对已发表的文献进行了综述。最初，选择了四个电子数据库，包括 Embase、Medline、Scopus 和 Web of Science，根据主要搜索中使用的选定关键字，从 2006 年 1 月 1 日至 2017 年 12 月 31 日检索已发表的研究。消除重复项后，对标题进行了审查，以确定其与主要研究问题的相关性。其次，对被认为相关的标题摘要进行了审查，以确定其重要性，最后对文章进行了全面审查，以确定其对主要研究问题的贡献。最初，确定了 8201 篇文章，最终有 8 项研究符合纳入标准。在第二阶段，对关键确定文章的参考文献进行审查后，又发现了三项研究。因此，最终选择了 11 篇论文进行综述。目前的文献证实，全球范围内温度与传染性肠胃炎之间存在显著关联。此外，还发现降雨量与 GI 感染之间存在最有可能的非线性相关性，即这种感染的发生率可能会因降雨量高或低而增加。最后，一些研究表明高相对湿度不一定会增加 GI 感染的发生率，而有些研究则发现高相对湿度可能会降低感染率。这些发现有助于预测风险，特别是在未来气候变化情景下。
