单纯性肥胖儿童心血管功能的测定

Examination of cardiovascular function in children with simple obesity

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 The aim of this study was to elucidate the relationship between simple obesity of children and cardiovascular function Methods The cardiovascular function was examined by noninvasive techniques (impedence cardiography ) in 90 children with simple obesity and 30 normal children. Results The cardiovascular data were compared using analysis of variance with the aid of computer. The results indicated that SBP was different in different groups (P < 0.01 ) and increased with obesity; obesity closely correlated with QS2 , PEP and IVCT. Conclusion impedence cardiogram can reflect the hemodynamic changes in the children with simple obesity and SBP, QS2, PEP and IVCT are better indexes than the others.
