【摘要】：目的了解冬季霧霾天氣對某市小學生肺功能影響,為防治小學生呼吸系統(tǒng)疾病提供依據(jù)。方法根據(jù)中國空氣質(zhì)量在線監(jiān)測分析平臺2016年數(shù)據(jù),在某市選取PM2.5污染相對較輕和污染相對較重監(jiān)測點,在監(jiān)測點附近2 km范圍內(nèi)各選擇1所小學,每所小學隨機抽取三~五年級各1個班,于供暖期前非霧霾天氣和供暖期間霧霾天氣分別進行1次肺功能測試。第1次肺功能測試調(diào)查362名學生,第2次359名,其中完成2次肺功能測試者338名。結(jié)果 2所學校學生身高、體重差異均無統(tǒng)計學意義(P值均0.05)。非霧霾日,輕污染區(qū)小學男生FVC低于重污染區(qū)小學男生(P0.05),輕污染區(qū)小學女生PEF高于重污染區(qū)小學女生(P0.05),輕污染區(qū)小學總體FEF75高于重污染區(qū)小學(P0.05)。輕污染區(qū)小學男生的FVC非霧霾日高于霧霾日(P0.05),女生FEV1,PEF,FEF25,FEF75在非霧霾日均高于霧霾日(P值均0.05);重污染區(qū)小學男生和總體FVC非霧霾日高于霧霾日,FEF75非霧霾日低于霧霾日(P值均0.05)。結(jié)論霧霾天氣對小學生肺功能有一定影響。應加大空氣污染治理力度,保證小學生健康成長。
[Abstract]:Objective to investigate the effects of winter haze weather on pulmonary function of pupils in a city and to provide evidence for prevention and treatment of respiratory diseases. Methods according to the 2016 data of China Air quality online Monitoring and Analysis platform, PM2.5 pollution and pollution monitoring points were selected in a certain city, and one primary school was selected within 2 km of the monitoring site. One class from grade 3 to grade 5 was randomly selected in each primary school. Lung function tests were performed on non haze weather before heating period and haze weather during heating period. The first pulmonary function test was conducted in 362 students and the second 359 students, of whom 338 completed two pulmonary function tests. Results there was no significant difference in height and weight between the two schools (P = 0.05). On non- day, the FVC of boys in light polluted areas was lower than that of boys in heavily polluted areas. The PEF of girls in light polluted areas was higher than that of girls in heavily polluted areas. The total FEF75 of light polluted primary schools was higher than that of heavily polluted primary schools. The FVC non- days of primary school boys in light polluted areas were higher than that of haze days (P 0.05), and that of girls was higher than that of haze days (P = 0.05), and that of boys and general FVC non- days was higher than that of haze days (P < 0.05). Conclusion haze weather has a certain effect on pulmonary function of primary school students. Should increase air pollution control efforts to ensure the healthy growth of primary school students.
