目的探讨儿童期单纯性肥胖与心血管功能的关系，为某些疾病的防治提供参考数据。方法用无创性方法（心阻抗法）测量单纯性肥胖儿童（90例）和正常儿童（30例）的心血管功能。资料借助于计算机进行了方差分析。结果收缩压(SBP)组间差异显著（P＜001），且随着肥胖程度逐渐升高；肥胖程度与QS2、PEP、IVCT密切相关.结论阻抗血流图能反映单纯性肥胖儿童的血液动力学变化，SBP、QS2、PEP、IVCT指标更敏感。
Objective To explore the relationship between childhood simple obesity and cardiovascular function and to provide reference data for the prevention and treatment of some diseases. Methods The noninvasive method (heart impedance method) was used to measure the cardiovascular function of simple obesity children (90 cases) and normal children (30 cases). Data were analyzed using ANOVA. Results SBP was significantly different between the two groups (P <0.001), and gradually increased with the degree of obesity.The degree of obesity was closely related to QS2, PEP and IVCT.Conclusion The impedance blood flow map can reflect the hemodynamics of simple obesity children Changes in learning, SBP, QS2, PEP, IVCT indicators more sensitive.
