摘　　要：本文对144名8～12岁男女儿童的肺通气功能指标进行测量，通过测量肱三头肌部和肩胛下角部皮脂厚度并以此二处皮指厚度之和推算体脂百分比的方法获得准确的体成分，用体脂百分比判定肥胖．结果：在各项肺通气功能指标中，补吸气率、静息通气量肥胖组高于对照组，补呼气率肥胖组低于对照组，余者两组间无显著性差异；单位体重、瘦体童、体脂肪的肺通气功能各指标值，除补吸气率／瘦体重、静息通气量／瘦体重两组无差异外，余者均为肥胖用低于对照组，表明儿童肥胖已引起肺通气功能不足．Vital capacity (VC) and various pulmonary functions were measured in 144 children aged 8~12. Theywere divided into two groups based on their percentage of body fat (%BF) which was calculated from theskinfolds of triceps and subscapular. Differences in pulmonary function measurements between the groupswere not siguificant except that inspiratory reserve volume to VC ratio (ERV%) and minute ventilation(MV) were significantly increased and that expiratory reserve volume to VC ratio (ERV% ) was significantlydecreased in the obese children. The measures of pulmonary functions on the basis of weight per unit. leanbody mass (LBM) and body fat (BF) were significantly decreased in obese group as compared with the control group except that IRV%/LBM. MV/LBM between the two groups were similar. The results suggestedthat simple obesity in children might lead to pulmonary vetilation deficiency.
