合肥市6～12岁健康小学生肺功能指标及其相关因素的调查

Pulmonary functions and the related factors among pupils in Hefei

目的了解本地区6—12岁健康小学生儿童肺功能正常值，探讨相关影响因素。方法对合肥市某小学70名在校健康小学生，采用德国Jaeger公司生产Master Screen Paed型肺功能仪检测常规通气肺功能。结果肺功能实测值随年龄增长而增大。身高、坐高、臂长、胸围、头围与肺功能的回归系数（β值）为正数，P值〈0．05或0．10。体重与肺功能各指标的P〉0．05。臂围与FVC的β值为负数，P〈0．10。结论年龄、身高对肺功能影响较大，呈正相关，其次为坐高、臂长、胸围。体重、臂围、头围对肺功能影响较小。

Aim To investigate the normal reference values of pulmonary functions and explore the related influential factors among the 6 to 12 year-old primary school health students in a primary school in Hefei. Method Samples of these 70 health students were taken by randomization. Routine ventilation lung functions were performed on the pulmonary function instrument：, Master Screen Paed, which was made by the Germany Jaeger company. Results Overall, the actually measured values of lung functions increased with the increase of the age. Still more, it was shown that the regression coefficient between height, sitting height, length of arm, circumference of chest ,circumference of head and all the measured pulmonary function is as follows ：β 〉 0, and P 〈 0.05 or P 〈 0.10. However,the regression coefficient between the values of pulmonary function and weight P 〉 0.05, circumference of arm β 〈 0, P 〈 0.10. Conclusions Through this investigation, we performed the analysis of the correlation between all the physical growth indicators and pulmonary function. Results showed that age and height were more related to lung function, and positive correlation was displayed. Next to height were sitting height, length of arm and circumference of chest related to lung function, and weight, circumference of arm and circumference of head were less related to lung function.
