【摘要】：目的探讨空气污染对济南市某医院呼吸系统疾病的短期影响及在人群中的差异。方法收集济南市某医院2010年1月1日至2012年12月31日呼吸系统疾病门诊资料、同期气象及空气污染数据,采用分布滞后非线性模型和温度分层等方法研究空气污染的滞后效应及其与气温的交互作用。结果空气污染当日即可引起呼吸系统门诊量升高,且效应可持续18 d;空气污染指数每升高10时,14 d累积效应可使呼吸系统门诊量增加4.26%(95%CI:1.89%~6.69%);将日最高气温按照P10和P90分为低、中、高3个水平后,空气污染指数每升高10可使呼吸系统疾病门诊量分别增加0.24%(95%CI:-4.65%~5.39%),2.54%(95%CI:0.55%~4.57%)和11.24%(95%CI:4.69%~18.20%),其中高温与空气污染的交互作用有统计学意义(P0.05),且在0~14岁人群中效应更明显。结论空气污染加重会导致呼吸系统疾病门诊人数升高且持续时间较长,并与高温有交互作用。提示高温天气时更应加强对空气污染的防护,尤其应关注儿童等脆弱人群。
[Abstract]:Objective to investigate the short-term effects of air pollution on respiratory diseases in a hospital in Jinan. Methods the clinic data of respiratory diseases from January 1, 2010 to December 31, 2012 in a hospital in Jinan were collected, and the meteorological and air pollution data were collected during the same period. The hysteresis effect of air pollution and its interaction with air temperature are studied by using distributed lag nonlinear model and temperature stratification. Results on the day of air pollution, the respiratory outpatient quantity was increased, and the effect lasted for 18 days. The cumulative effect of every 10:00 and 14 days increase in air pollution index could increase the respiratory outpatient volume by 4.26 and 95% CI: 1.89 and 6.690.The daily maximum temperature was classified as low according to P10 and P90. After three levels, every 10 increase in the air pollution index can increase the number of outpatients with respiratory diseases by 0.24%, 95% -4.65% and 5.39%, respectively. The air pollution index increases by 2.545.95% 0.55CI: 4.57g) and 11.2495CI: 4.69% 18.200.The interaction between high temperature and air pollution is statistically significant, and the effect is more obvious among the people aged 014. Conclusion the increase of air pollution will lead to an increase in the number of outpatients with respiratory diseases and a longer duration, and it will interact with high temperature. It is suggested that the prevention of air pollution should be strengthened in high temperature weather, especially for the vulnerable groups such as children.
