上海市某郊区学校儿童肺功能测定结果分析

Pulmonary Function Analysis of Children in a Suburb School of Shanghai

摘要

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(FEV_1.0)、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(FEF_25%)、用力呼出50%肺活量的呼吸流速(FEF_50%)、用力呼出75%肺活量的呼吸流速(FEF_75%)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、FEV_1.0、PEF、FEF_25%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。

Abstract:
Objective To analyze the pulmonary function of children in a suburb school of Shanghai.

Methods Pulmonary 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 (FEV_1.0), peak expiratory flow (PEF), forced expiratory flow (FEF) between 25% and 75% of FVC (FEF₂₅₇₅), FEF at 25% of FVC (FEF_25%), FEF at 50% of FVC (FEF_50%), and FEF at 75% of FVC (FEF_75%) were positively correlated with weight and age, particularly with height, in both gender groups. Indicators such as FVC, FEV_1.0, PEF, and FEF_25% 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.
