摘要
[目的]了解上海市某郊区学校儿童的肺功能基本情况。[方法]对上海市某郊区小学的3～5年级学生进行肺功能检查。[结果]男女生肺功能主要指标如用力肺活量(FVC)、一秒钟用力肺活量(FEV1.0)、峰值呼气流速(PEF)、用力呼气中段流速(FEF2575)、用力呼出25%肺活量的呼吸流速(FEF25%)、用力呼出50%肺活量的呼吸流速(FEF50%)、用力呼出75%肺活量的呼吸流速(FEF75%)等与身高、体重和年龄均呈密切正相关,且与身高的关系最为密切;男生FVC、FEV1.0、PEF、FEF25%高于女生;有17.9%者显示肺通气功能受损,另有6.6%者可能发生早期小气道病变。[结论]肺功能测定是儿童呼吸系统的重要检测手段;儿童肺功能检测中,小气道指标对肺功能早期改变的意义尤其重要。
[ Objective ] To analyze the pulmonary function of children in a suburb school of Shanghai. [ Methods ] Pulmon .ary function tests were performed among children of grade 3 to 5 from a suburb primary school in Shanghai. [ Results ] The results of multiple regression analysis showed that forced vital capacity （FVC）, forced expiratory volume in one second （FEVL0）, peak expiratory flow （PEF）, forced expiratory flow （FEF） between 25% and 75% of FVC （FEF257s）, FEF at 25% of FVC （FEF2s~）, FEF at 50% of FVC （FEFs0~）, and FEF at 75% of FVC （FEF75~） were positively correlated with weight and age, particularly with height, in both gender groups. Indicators such as FVC, FEV10, PEF, and FEF25% were remarkably higher in boys than in girls. The abnormal rate of pulmonary ventilation function was 17.9%, and 6.6% of the children had early small airway disorders. [Conclusion] Pulmonary function test is important in the evaluation of children＇s respiratory system, and the indicators of small airway are of great value to predict the abnormality of pulmonary function.
