本研究调查了中国杭州儿童轮状病毒感染率是否与温度和空气污染物有关。本研究应用分布式滞后非线性模型（DLNM）评估每日气象数据和空气污染物对门诊儿童轮状病毒阳性率的影响。温度与轮状病毒感染率呈负相关。温度对轮状病毒检出率的影响呈现明显的滞后效应，温度变化对轮状病毒检出率的影响大约在滞后1天时最大，最大相对风险（RR）约为13。2015年，由于气温下降造成的累积效应，累积RR最大为2.5。颗粒物（PM）2.5和PM10是杭州市主要空气污染物。轮状病毒感染的最高RR出现在这些污染物浓度增加后滞后1-1.5天，并且。随着浓度的增加，RR逐渐增加。以2015年杭州市PM2.5平均浓度53.9μg/m(3)和PM10平均浓度80.6μg/m(3)计算，累积效应造成的累积RR分别为2.5和2.2。目前的研究表明，温度是影响杭州市儿童轮状病毒感染率的重要因素。空气污染物显着增加轮状病毒感染的风险，并观察到剂量、滞后和累积效应。 (C) 2016 Elsevier Ltd. 保留所有权利。
This study investigated whether the rotavirus infection rate in children is associated with temperature and air pollutants in Hangzhou, China. This study applied a distributed lag non-linear model (DLNM) to assess the effects of daily meteorological data and air pollutants on the rotavirus positive rate among outpatient children. There was a negative correlation between temperature and the rotavirus infection rate. The impact of temperature on the detection rate of rotavirus presented an evident lag effect, the temperature change shows the greatest impact on the detection rate of rotavirus approximate at lag one day, and the maximum relative risk (RR) was approximately 13. In 2015, the maximum cumulative RR due to the cumulative effect caused by the temperature drop was 2.5. Particulate matter (PM) 2.5 and PM10 were the primary air pollutants in Hangzhou. The highest RR of rotavirus infection occurred at lag 1-1.5 days after the increase in the concentration of these pollutants, and. the RR increased gradually with the increase in concentration. Based on the average concentrations of PM2.5 of 53.9 mu g/m(3) and PM10 of 80.6 mu g/m(3) in Hangzhou in 2015, the cumulative RR caused by the cumulative effect was 2.5 and 2.2, respectively. The current study suggests that temperature is an important factor impacting the rotavirus infection rate of children in Hangzhou. Air pollutants significantly increased the risk of rota virus infection, and dosage, lag and cumulative effects were observed. (C) 2016 Elsevier Ltd. All rights reserved.
