减肥对肥胖儿肺功能的影响

Effect of weight reduction on pulmonary function in obese children

目的观察减肥前后肥胖儿肺功能的变化,探讨减肥对肥胖儿的影响,从而为儿童单纯性肥胖症的防治提供科学依据。方法收集10~11岁单纯性肥胖症儿童40例,同时选取体重正常健康儿童40例作为对照组,肥胖儿童进行为期9个月的综合干预,包括行为干预、饮食调整、运动锻炼。测定其减肥前后用力肺活量、1秒钟用力呼气量、最大呼气流速,并与对照组儿童相比较。结果肥胖儿童用力肺活量、1秒钟用力呼气量、最大呼气流速均低于正常儿童,减肥后明显升高。结论肥胖儿童存在肺功能损害,减肥可改善肥胖儿肺功能。

Objective To explore the changes of cardiac function in obese children before and after weight reduction and evaluate the influence of weight reduction on obese children.Methods Forty children with obesity at the age of 10 to 11 years old and forty normal children were enrolled in this study.The obese children received a session of comprehensive intervention including health education,dietary adjustment,exercise and behavior intervention for 9 months.Results Forced vital capacity（FVC）,forced expiratory volume in one second（FEV1）,peak expiratory flow（PEF） in the obese children were lower than normal children,and significantly increased after weight reduction.Conclusion Obesity seriously affects pulmonary function in obese children and cardiopulmonary function can be improved by weight reduction.
