【摘要】：目的了解常州市大氣污染對小學(xué)生患病情況和肺功能的影響,為采取有效措施控制疾病發(fā)生及改善肺功能提供參考。方法在常州市武進區(qū)隨機選擇1所小學(xué),按整群隨機抽樣的方法選取小學(xué)三至五年級共634名學(xué)生,對研究對象開展問卷調(diào)查和肺功能檢測,結(jié)合環(huán)境監(jiān)測的結(jié)果,分析霧霾天氣對小學(xué)生患病情況及肺功能的影響。結(jié)果霧霾當(dāng)天共有99人次患相關(guān)疾病,其中以呼吸系統(tǒng)疾病為主(63人次,占63.6%),其次為感染性疾病(16人次,占16.2%);霧霾日小學(xué)生的肺功能指標(biāo)中的用力肺活量(FVC)、1s用力呼吸量(FEV1)、呼氣峰值流速(PEF),75%FVC時的用力呼氣流量(V75)[(1.68±0.44)L,(1.60±0.40)L,(2.86±1.10)L/s,(2.66±1.11)L]水平均低于非霾日[(1.48±0.49)L,(1.40±0.42)L,(2.26±1.01)L/s,(1.99±1.04)L],差異均具有統(tǒng)計學(xué)意義(P值均0.01)。結(jié)論大氣污染與小學(xué)生患病人數(shù)增加和肺功能下降有一定關(guān)聯(lián)。應(yīng)采取有效措施改善空氣質(zhì)量。
[Abstract]:Objective to investigate the effects of air pollution on the prevalence and pulmonary function of primary school students in Changzhou, and to provide reference for effective measures to control the occurrence of diseases and improve lung function. Methods A random primary school was selected in Wujin District of Changzhou City. 634 students from grade 3 to grade 5 were selected according to cluster random sampling method. The subjects were investigated with questionnaire and lung function test, combined with the results of environmental monitoring. To analyze the influence of haze weather on the prevalence and lung function of primary school students. Results on the day of haze, 99 patients suffered from related diseases, of which 63 were respiratory diseases (63.6%), and the next were infectious diseases (16 patients). 鍗，
