儿童体脂指数实效性与肥胖评价标准的研究

Effect of Body Fat Index and Evaluation Standard of Obesity

通过对儿童BM I的判定标准的实效性分析,探寻更为理想的体脂评价方法,为制定儿童肥胖防治和健康促进策略提供依据。结论：原模型应用于7-12岁学生不适宜,其标准存在明显的偏高性,该模型应用该人群实效不够理想;7-12岁城市学生的BM I指数存在年龄、性别差异,对该类人群的MB I评价不适宜进行年龄和性别的合并;改进模型判定标准实效理想,改进模型克服了原模型的偏性的不足,其客观性、合理性、精确性均明显优于原模型。

By analyzing actual effect of BMI evaluation standard in children,and for searching more effective evaluation method of body fat,we provide a basis for prevention and cure of obesity and health promotion strategies.Conclusion：The original model which applied to 7-12 years old students was not appropriate,for its criterion was significantly higher.The actual effect of the original model was not ideal enough.BMI has difference in 7-12 years old urban students.It was not appropriate for the crowd to merged age with gender.Actual effect of improved mode are perfect.The improved model overcomes the shortcoming of the bias of original model.The objectivity,rationality and accuracy of improved model,which was better than that of the original model.
