百色市壮族幼儿营养指数与皮褶厚度的相关分析

Correlation analysis of nutrition index and skinfold thickness of Zhuang nationality children in Baise

目的：探讨壮族幼儿营养指数与皮褶厚度的相关性，为少数民族幼儿营养干预工作提供理论依据。方法：测量壮族幼儿身高、体质量、坐高、肱三头肌皮褶、肩胛下皮褶、髂前上棘皮褶和腓肠肌皮褶7项指标，计算Kaup指数和Pelidisi指数值，分析壮族幼儿Kaup、Pelidisi两项营养指数和皮褶厚度相关性。结果：女性幼儿4项皮褶厚度值高于男性幼儿；壮族幼儿皮下脂肪发育与新疆哈萨克族、济宁市城镇和乡村不同；Kaup指数与皮褶厚度的相关系数大于Pelidisi指数与皮褶厚度的相关系数；Kaup指数估计肱三头肌皮褶与肩胛下皮褶和的回归方程y（男3-6岁）：1．025＋O．764x，y（女3-6岁）=1．142＋O．861x。结论：壮族幼儿皮下脂肪发育存在性别、年龄和民族差异。可以采用Kaup指数法推算皮褶厚度，评价幼儿营养状况。

Objective： To explore the nutrition index and skinfold thickness correlation in Zhuang children and provide theoretical basis in nutrition interventions for ethnic minority children. Methods： Measure the height,weight, sitting height, tri- ceps thicknesses, subscapular thicknesses, suprailiac thicknesses and calf thicknesses of the childrens from Zhuang ethnic group. Calculate the Kaup and Pelidisi index and analyze the correlations of Kaup and Pelidisi index with two skinfold thicknesses. Results.. Females had the thicker skinfolds than males. There was difference in the development of the subcutaneous fat between Kazak, Jining city and rural. The correlation coefficient of Kaup index with skinfold thickness was greater than Pelidisi index, y（male）=1. 025＋0. 764x, y（female）= 1. 142＋0. 861x regression equation of triceps and subscapular skin- folds sum was estimated from the Kaup index. Conclusion： The development of the subcutaneous fat was different in sex, age and ethics. Kaup index can be used to calculate the skinfold thickness and evaluate the nutritional status of children.
