【摘要】：目的了解北京市海淀区儿童青少年体成分特征,为预防儿童青少年超重肥胖提供依据。方法随机选取海淀区807名参加体能测试的中小学生进行体成分测量,测量项目包括体脂肪量、总水分、蛋白质、无机盐。运用SPSS22.0对数据进行统计分析。结果 807名儿童青少年超重率为21.2%,其中男生为24.6%,女生为17.9%;肥胖率为13.0%,其中男生为16.2%,女生为9.9%。儿童青少年肥胖组和超重组的体成分均大于非超重组,差异均有统计学意义(P值均0.05);肥胖组和超重组比较,只有BMI和体脂肪量差异有统计学意义(t男值分别为-7.780,-7.646;t女值分别为-5.096,-3.771,P值均0.05)。男生6~12岁阶段的体脂肪量逐年增加,均值从5.07 kg增加到14.79 kg,13岁开始逐年减少,女生的体脂肪量逐年增加,均值从5.17 kg增加到15.78 kg,差异均有统计学意义(P值均0.01);男、女生的总水分、蛋白质、无机盐逐年增加,差异均有统计学意义(P值均0.01)。结论儿童青少年的体成分随着年龄的增长一直在变化,且存在性别差异。
[Abstract]:Objective to understand the body composition characteristics of children and adolescents in Haidian district of Beijing, and to provide evidence for prevention of overweight and obesity among children and adolescents. Methods 807 primary and middle school students in Haidian district were randomly selected to measure body composition, including body fat, total moisture, protein and inorganic salt. The data were statistically analyzed by SPSS22.0. Results the overweight rate of 807 children and adolescents was 21.2% (24.6% for boys and 17.9% for girls) and 13.0% for boys (16.2% for boys and 9.9% for girls). The body composition of obesity group and overweight group was higher than that of non-overweight group, the difference was statistically significant (P < 0.05). Compared with overweight group, only BMI and fat content were significantly different (t male =-7.780, female =-5.096, P = 3.771, P = 0.05). The body fat weight of boys at the age of 6-12 years increased year by year, the average value increased from 5.07 kg to 14.79 kg,13 years old and decreased year by year, while the body fat mass of girls increased year by year from 5.17 kg to 15.78 kg,. The difference was statistically significant (P < 0.01).
