摘要

目的探讨天津市大气污染物暴露对心血管系统和呼吸系统疾病急救量的短期影响.方法收集2020年1月1日至2022年11月30日的天津市每日环境空气质量数据、气象数据和急救中心接诊数据.利用广义线性模型,探讨大气污染物暴露对急救量的短期影响.结果 2020-2022年心血管疾病急救量共48 445人次,呼吸系统疾病急救量共67 983人次.PM2.5浓度每增加10 μg/m3,累积滞后1 d的心血管疾病急救量增加0.39％(95％CI:0.01％～0.78％).NO2浓度每增加10 μg/m3,累积滞后1 d的心血管疾病急救量增加1.18％(95％CI:0.41％～1.95％);SO2浓度每增加10μg/m3,当日心血管疾病急救量增加2.64％(95％CI:0.02％～5.23％).未见各大气污染物暴露对呼吸系统疾病急救量的短期影响.结论大气PM2.5、NO2和SO2浓度的升高可能导致心血管疾病急性发病风险增加.

Abstract

Objective To understand the short-term effect of air pollutants exposure on cardiovascular and respiratory emergency visits in Tianjin.Methods The daily data of Tianjin from 2020 to 2022 were collected,including the concentration of air pollutants,emergency visits and the meteorological data.The generalized linear model was used to explore the effect of air pollution on emergency visits.Results A total of 48 445 cases of the cardiovascular disease and 67 983 cases of the respiratory system emergency visits were collected during the study period.Each 10 μg/m3 increase in the concentration was associated with a higher incidence of cardiovascular emergency visits for PM2.5(0.39％,95％CI:0.01％-0.78％),NO2(1.18％,95％CI:0.41％-1.95％)and SO2(2.64％,95％CI:0.02％-5.23％),respectively,and no significant short-term effect of air pollutants exposure on emergency visits for respiratory diseases was observed.Conclusion The elevated levels of atmospheric PM2.5,NO2 and SO2 may increase the risk of cardiovascular emergency visits.
