Although multiple combinations of weather variability may contribute to an increased incidence of infectious gastrointestinal disease, few studies have investigated the association between weather variability and cases of infectious gastroenteritis. We acquired data for infectious gastroenteritis cases and weather variability in Fukuoka, Japan, from 1999 to 2007 and used time-series analysis to assess the effects of weather variability on infectious gastroenteritis cases, adjusting for confounding factors. In total, 422,176 infectious gastroenteritis cases were reported during the 9-year study period. The weekly number of infectious gastroenteritis cases increased by 7.7% (95% CI 4.6-10.8) for every 1 degrees C increase in the average temperature and by 2.3% (95% CI 1.4-3.1) for every 1% decrease in relative humidity. From 1999 to 2007, infectious gastroenteritis cases increased significantly with increased average temperature and decreased relative humidity in Fukuoka, Japan.
尽管多种天气变化组合可能导致传染性胃肠道疾病发病率增加，但很少有研究调查天气变化与传染性胃肠炎病例之间的关系。我们获取了日本福冈市 1999 年至 2007 年传染性胃肠炎病例和天气变化的数据，并使用时间序列分析来评估天气变化对传染性胃肠炎病例的影响，同时调整了混杂因素。在 9 年的研究期间，共报告了 422,176 例传染性胃肠炎病例。每周传染性胃肠炎病例数每增加 1 摄氏度，增加 7.7%（95%CI 4.6-10.8）；每降低 1%的相对湿度，增加 2.3%（95%CI 1.4-3.1）。1999 年至 2007 年期间，日本福冈市的传染性胃肠炎病例随着平均温度升高和相对湿度降低而显著增加。
