摘要
采用InBody体成分测试仪对 988名 3～6 岁幼儿进行测量,并对测量数据进行分析,以了解幼儿的身体形态和身体成分发展现状、规律及相关关系.结果显示:男女幼儿的体重在3～3.5岁、4～4.5岁、5～5.5岁3个年龄段有统计学意义(P＜0.05),男幼儿大于女幼儿;男女幼儿的总水分、蛋白质、骨骼肌均随年龄的增长而增长,各年龄段均有统计学意义(P＜0.05),男幼儿大于女幼儿;男女幼儿的无机盐随年龄的增长而增长,但体脂率、肥胖率则随年龄的增长而下降;男女幼儿的身高与年龄、体重、总水分、蛋白质、无机盐、体脂肪、骨骼肌、身体质量指数(BMI)显著正相关(P＜0.01),与体脂率负相关,但无统计学意义(P＞0.05);男女幼儿的体重、体脂肪与所有指标显著正相关(P＜0.01).
Abstract
In order to understand the status,development discipline and relationship of the body shape and body composition of children who are 3-6 years old,the InBody body composition tester has been used to measure 988 children,and the measurement data is analyzed.The results show that the body weight is statistically significant in three age groups:3-3.5 years old,4-4.5 years old and 5-5.5 years old(P<0.05),which of male children are significantly greater than that of female children.The total water content,protein and skeletal muscle of male and female children increase with age(P<0.05);Minerals also increased with age,but body fat percent and obesity rate decreases with age.The height of male and female children is significantly positively correlates with age,weight,total water,protein,minerals,body fat,skeletal muscle and body mass index(BMI)(P<0.01),and negatively correlates with body fat percent,but there is no statistical significance(P＞0.05);The weight and body fat are significantly positively correlated with all indexes(P<0.01).
