背景资料：胃肠道感染，一个重大的公共卫生问题，全球范围内，已与单一的天气因素，但多种天气因素对胃肠道infecties.Methods的联合作用仍不清楚：我们进行了一项回顾性时间序列分析，调查影响的天气条件对住院胃肠道感染（GIH）在纽约州从1991年至2004年7月和8月。应用广义加性模型（GAM），我们评估了日GIH计数与温度，湿度和降水等多种天气因子的关系（0-10滞后天），调整长期趋势、季节性和日历效应。结果：最高温度，最低温度，和最高通用表观温度（UAT）表明，温度每升高摄氏度，（0.70-0.96%），在滞后1时观察到的影响最大。极热（EH：>第90百分位数）（滞后1时为3.68%）和降水（滞后4时为0.31%）对GIH的增加有较大影响，且EH存在明显的剂量-反应关系。分层分析表明，极端高温对GIH的影响往往是更大的西班牙裔，黑人，女性，和那些与细菌infections.Conclusion：我们发现，高的最高和最低温度，UAT，降水，夏季极端高温显着增加了纽约州GIH的风险。我们的研究结果还表明，细菌可能是夏季GIH的重要原因，少数民族，女性和细菌感染者可能更容易受到高温对GIH的影响。(C)© 2016 Elsevier B.

Background: Gastrointestinal infections, a substantial public health problem worldwide, have been associated with single weather factors but the joint effect of multiple weather factors on gastrointestinal infections remains unclear.Methods: We conducted a retrospective time-series analysis to investigate effects of weather conditions on hospitalizations for gastrointestinal infections (GIH) in New York State in July and August from 1991 to 2004. Applying generalized additive model (GAM), we evaluated the associations between daily GIH count and multiple weather factors including temperature, humidity, and precipitation (0-10 lag days), adjusting for long term trend, seasonality, and calendar effects.Results: Maximum temperature, minimum temperature, and maximum universal apparent temperature (UAT) showed that each degrees C increase in temperature was significantly associated with an increase (0.70-0.96%) in daily GIH count, with the greatest impacts observed at lag 1. Extreme heat (EH: >90th percentile) (3.68% at lag 1) and precipitation (0.31% at lag 4) showed larger impacts on increases of GIH and a clear dose-response relationship for EH. Stratified analyses showed that the impacts of extreme heat on GIH tend to be greater among Hispanics, blacks, females, and those with bacterial infections.Conclusion: We found that high maximum and minimum temperature, UAT, precipitation, and extreme heat in summer significantly increased the risks of GIH in NYS. Our findings also suggest that bacteria might be a significant cause for GIH in the summer, and minority, female and those with bacterial infection may be more vulnerable to heat's effects on GIH.
