单纯肥胖儿童心脏体积及其增大发生率与肥胖度关系

目的：了解单纯肥胖儿童心脏体积与正常体重儿童的差异和不同程度肥胖心脏体积增大发生率。提供不同程度肥胖儿童心脏体积X线解剖数据。方法：用X线测定正常和单纯肥胖儿童心脏体积，对正常体重儿童和不同程度肥胖儿童心脏体积及其增大发生率进行统计学分析。建立用胸围预测肥胖儿童心脏深径的直线回归方程。结果：正常体重儿童、轻度、中度、重度肥胖四者比较，肥胖程度越重，心脏体积越大。肥胖儿童心脏体积非常显著地大于正常儿童。结论：随着肥胖程度的加重心脏体积及其增大发生率增大。肥胖影响了儿童心脏形态大小和功能，降低心血管疾病的发病率必须从儿童做起。

Relationship between heart volume and its extension incidence with obese degree in simple obesity children

Objective: To ascertain whether there exists difference of heart volume between simple obese children and those with normal weight from 3-7 years old and the extension incidence rate of different heart volume of different obese children. Methods: The heart volumes of 464 simple obese children, aged 3-7 years, were measured and compared with those normal children. Statistical analysis was performed on the heart volumes of normal children and the children with light,middle,severe weight and on the extension incidence rates of different heart volumes. The regression equations for predicting the heart deep diameter of simple obese children with the chest circumference was established by linear regressive analysis. Results: The heart volumes of middle and severe obese children were larger than that of light obese children. The heart volumes among the 4 groups of normal weight children,light,middle,severe obese children had statisticallg significant differences (P<0.01). The more serious the obese degree became,the bigger the heart volume was. In every age group regardless of age group,the heart volumes between obese children and normal weight children were quite different (P<0.01). With the increase of obese degree,the incidence of the heart volume increased. Conclusion: The heart volume of simple obese children is obviously larger than that of normal children. With the increase of obesity degree,the heart volume and its extension incidence increases. The shape and size of the heart and the cardiac function have been affected by obesity.so to prevent the cardiovascular system diseases,we must start from children.
