摘要:

基于2014—2018年深圳市罗湖区49家社区健康服务中心上呼吸道感染(简称“上感”)的逐日就诊人数和同期气象要素资料,利用不同时间尺度分析上感就诊人数的变化特征,并采用分布滞后非线性模型(DLNM)、广义线性模型(GLM)等研究不同气象要素与深圳地区上感就诊人数的关系。结果表明:深圳市罗湖区上感就诊人数存在明显的季节性变化,春季3—4月、夏季7月和冬季12月至次年1月为发病高峰时段,分别对应24节气中的清明、小暑、小寒节气。DLNM反映气温为主控因素,它对上感就诊人数的影响以冷效应为主,相对风险(RR)在滞后4 d达到峰值(RR为1.041,95%置信区间为1.022~1.060),且女性较男性、中老年人较少儿更易受冷效应的影响;其次是暑期的热效应和春季温度多变的影响。湿度影响主要表现为低湿效应,其相对风险在当天达到峰值(RR为1.058,95%置信区间为1.049~1.068)。气压和风速影响则表现为高压效应和大风效应,RR在滞后1 d达最高。总之,深圳市冬、春季冷空气活动及其所反映的低温、低湿、大风等产生的冷效应是诱发上呼吸道感染的关键因素,其次是夏季持续高温的影响,两者都应予以重点及时防范。

Abstract:

The daily number of patients with upper respiratory tract infection (URI) in 49 community health service centers in Luohu of Shenzhen from 2014 to 2018 and meteorological data in the same period were collected to analyze the changing characteristics of the number of patients with URI at different time scales. The distributed lag non-linear model (DLNM) and generalized linear model (GLM) were used to study the relationship between different meteorological factors and the number of patients with URI in Shenzhen. The results show that there was a significant seasonal change for the number of patients with URI in Luohu of Shenzhen. The peak periods of cases were March to April in spring, July in summer and December to next January in winter, corresponding to Pure Brightness, Lesser Heat and Lesser Cold of the 24 solar terms, respectively. The DLNM model showed that air temperature was the main impact factor, and its effect on the number of patients with URI presented mainly cold effect, the relative risk (RR) reached the peak after 4 days lag (RR was equal to 1.041, the 95% confidence interval was between 1.022 and 1.060). Women were more affected by cold effect than men, and middle-aged and elderly people were more affected by cold effect than children. Another important factors were thermal effect in summer and the variable temperature in spring. The influence of humidity presented mainly low humidity effect, and the relative risk reached the peak (RR was equal to 1.058, the 95% confidence interval was between 1.049 and 1.068) on the same day. Pressure and wind speed showed high pressure effect and strong wind effect, and RR reached the highest after 1 day lag. In conclusion, cold air activities in winter and spring and their cold effects such as low temperature, low humidity and strong wind were the key factors to induce URI, followed by the impact of continuous high temperature in summer, both of them should be focused on timely prevention.
