目的 了解河北省不同地区大气O3污染现状,阐明O3对儿童呼吸系统疾病门诊就诊量的影响。方法 收集整理2015—2017年河北省儿童医院内科呼吸道疾病就诊人次,并获取同期环保与气象资料,采用非线性分布滞后模型(DLNM)计算O3对呼吸系统就诊量的超额风险度ER95%CI,采用滞后(1~16d效应以及累积(1~16d效应进行描述,并将效应最大值作为O3对门诊量影响的评估值。结果 ①2015—2017年石家庄市、唐山市及张家口市O3超标天数逐年增多,污染程度逐年加重;②3个城市O3日均浓度与门诊量具有统计学相关性(P<0.01);石家庄市、唐山市和张家口市O3对儿童呼吸系统就诊量均存在滞后效应,大气O3日均浓度每增加10 μg/m3,呼吸系统疾病门诊人次依次增加0.25%0.14%0.36%)、0.16%0%0.31%)和0.53%0.12%0.94%),张家口市影响最大,且O33个城市儿童呼吸系统门诊就诊人次的滞后效应影响变化趋势一致;石家庄市和张家口市O3对儿童呼吸系统疾病门诊人次有持续16 d的累积效应,在(13~14d时达到最大值,大气O3日均浓度每增加10 μg/m3,呼吸系统疾病门诊人次分别增加0.82%0.63%1.01%)和2.37%1.03%3.74%),张家口市影响最大,O33个城市呼吸系统门诊就诊人次的累积效应影响变化趋势一致;石家庄市和张家口市O3对于儿童呼吸系统疾病J00-J06和症状R07门诊人次存在滞后及累积效应,且O3J00-J06R07累积效应持续时间较长,并呈现逐渐上升趋势。结论 河北省不同地区O3对儿童健康影响存在地域性差异,进一步深入探索不同地区O3的成因及其对人群健康的影响迫在眉睫。

Objectives To understand the status of atmospheric Ozone pollution in different areas of Hebei province, and to clarify the impact of Ozone on the outpatient visits of children with respiratory diseases. Methods The number of children outpatients with respiratory diseases in Hebei Provincies Children's Hospital from 2015 to 2017 was collected and environmental and meteorological data during the same period were obtained. The distribution lag non-linear model (DLNM) was used to calculate the excess risk ER and 95%CI of Ozone for volume of respiratory system outpatients, described by the lag (1~16) day effect and the cumulative (1~16) day effect, and the maximum effect is used as an estimate of the effect of Ozone on the number of outpatients. Results ① From 2015 to 2017, the number of days with unqualified concentration of ozone in Shijiazhuang, Tangshan, and Zhangjiakou increased year by year, and the pollution level increased year by year. ② The daily average concentration of Ozone in Shijiazhuang, Tangshan, and Zhangjiakou was statistically correlated with the number of outpatients (P<0.01); ③ Ozone in Shijiazhuang, Tangshan, and Zhangjiakou have a lag effect on the number of children outpatients with respiratory system, with the daily average concentration of atmospheric Ozone increased by 10 μg/m3, the number of respiratory disease outpatients increases by 0.25% (0.14%, 0.36%), 0.16% (0%, 0.31%), 0.53% (0.12%, 0.94%), respectively. Zhangjiakou has the greatest impact, and the impact variation trend of Ozone on the lag effect of children's respiratory system outpatient visits in 3 cities is consistent. ④ Ozone in Shijiazhuang and Zhangjiakou have a cumulative effect on outpatients of children's respiratory diseases lasts for 16 days, reaching a maximum at (13~14) d, with an increase in atmospheric Ozone daily concentration of 10 μg/m3, the number of outpatients with respiratory disease increased by 0.82% (0.63%,1.01%) and 2.37% (1.03%,3.74%), respectively. Zhangjiakou had the greatest impact, and the impact variation trend of Ozone on the cumulative effect of the number of respiratory diseases outpatient visits in the three cities was consistent. ⑤ Ozone in Shijiazhuang and Zhangjiakou had lag and cumulative effects on children's respiratory diseases J00-J06 and symptom R07 outpatient visits, and the cumulative effect of Ozone on J00-J06 and R07 lasted longer, and showing a gradual upward trend. Conclusions There are regional differences in the impact of Ozone on children's health in different regions of Hebei province. It is extremely urgent to further explore the causes of Ozone in different regions and its impact on human health.
