目的探讨儿童注意力缺陷多动障碍(ADHD)儿童的呼吸功能,分析其注意力缺陷多动障碍的临床特征。方法以《美国精神障碍诊断与统计手册》第4版(DSM-Ⅳ)为诊断标准,选择40名ADHD儿童,按1∶1比例设对照组,采用两独立样本资料的t检验比较两组儿童的呼吸频率、幅度和最大呼气峰流速值,采用Pearson相关系数对ADHD儿童的IVA-CPT各商数与呼吸功能的关联性进行分析。结果①ADHD组儿童呼吸频率快于正常组儿童,而呼吸幅度和最大呼气峰流速值低于正常组儿童。②ADHD组儿童综合尺度反应控制商数(FSRCQ)、综合尺度注意力商数(FSAQ)、听觉反应控制商数(ARCQ)、视觉反应控制商数(VRCQ)、听觉注意力商数(AAQ)与呼吸频率呈负相关,与呼吸幅度及最大峰流速值呈正相关;而视觉注意力商数(VAQ)与频率呈负相关,与呼吸幅度呈正相关,但与最大峰流速值的相关无统计学意义。结论 ADHD与肺功能存在相关性,ADHD儿童可能存在浅快呼吸及肺容量小等缺陷,可作为ADHD的干预效果指标之一。

Objective To investigate the respiratory function and analysis their some clinical features on Attention deficit hyperactivity disorder children.Methods 40 ADHD children were selected using DSM-IV as diagnostic criteria,and the normal group were set up with the rate of 1∶1.Compare the Respiratory rate,extent,the peak flow between the two groups using t-test,and using Pearson correlation coefficient to analyse the relevance of quotient between IVA-CPT and respiratory function on ADHD children.Results ①Compared with normal children,ADHD children have higher Respiratory rate and lower the Respiratory extent and peak flow.②In ADHD group,FSRCQ,ARCQ,VRCQ have significant direct correlation with Respiratory extent and inverse correlation with Respiratory rate,the direct correlation with peak flow is significant on statistical;FSAQ,AAQ have direct correlation with Respiratory extent and peak flow;VAQ has direct correlation with Respiratory extent and inverse correlation with Respiratory rate,and has no correlation with peak flow.Conclusions ADHD children have light but fast respiration and small hung capacity,correlation analysis shows small hung capacity has relationship with ADHD.
