本工作测定了99例单纯性肥胖小儿的肺功能.结果显示单纯性肥胖小儿在7至10岁组不但体重超过正常同龄对照组(P<0.01),而且身高也明显超过对照组(P<0.01).他们的肺功能VC,FVC,FEV_1,PEFR/Ht,MVV,TLC 及FRC 等各项的平均值都高于对照组.其中MVV 和TLC 显著高于对照组,P<0.01.而在11至14岁组的单纯肥胖小儿,虽然体重仍大大超过正常同龄对照组,但身高已不再占优势.他们的肺功能VC、FVC,FEV_1,PEFR/Ht,MVV,TLC 及FRC 等各项的平均值都低于相应对照组.其中MVV,FRC 和PEFR/Ht 显著低于对照组,P 值分别为<0.01,<0.01和<0.05.这表明单纯性肥胖对11到14岁小儿比对7到10岁小儿在肺功能方面危害更大.探求其原因,可能是在10岁前营养和能量过剩除了造成小儿体内脂肪堆积外,对小儿的生长尚能起促进作用.在11岁以后营养和能量过剩对儿童可造成限制性通气功能障碍及气道阻力增大等肺功能损害,对他们的生长发育有弊无利。
This study measured the lung function of 99 simple obese children.The results showed that the obese children aged from 7 to 10 years not only weighed more than the normal control group (P <0.01), but also had a significantly higher height than the control group (P <0.01) ), And their mean pulmonary function VC, FVC, FEV_1, PEFR / Ht, MVV, TLC and FRC were higher than the control group, MVV and TLC were significantly higher than the control group, P <0.01, The 14-year-old simple obese children, whose body weight was still significantly higher than the normal age-matched control group, no longer gained their height. Their pulmonary function such as VC, FVC, FEV 1, PEFR / Ht, MVV, TLC and FRC The average values were lower than the corresponding control group, in which MVV, FRC and PEFR / Ht were significantly lower than the control group, the P values were <0.01, <0.01 and <0.05, indicating that simple obesity in children aged 11 to 14 compared with 7 To 10-year-old children in the lung function more harmful to explore the reason may be that before the age of 10 nutrition and excess energy in addition to causing children’s body fat accumulation, the growth of children can still play a catalytic role in nutrition and after 11 years of age Excess energy in children can cause restrictive ventilatory dysfunction and increased airway resistance and other lung function damage, to them The growth and development have both disadvantages and disadvantages.
