摘要
利用山东省1995年和2005年学生体质调研资料,分析了7—12岁城乡儿童皮褶厚度和体成分的变化趋势。10年间,7—12岁城男、城女、乡男、乡女皮褶厚度分别平均增长7.97mm、4.54mm、11.42mm、9.48mm,体脂比平均增长3.42%、2.07%、4.92%、4.35%,体脂肪平均增长2.34kg、1.27kg、2.82kg、2.30kg,瘦体重平均增长1.96kg、1.42kg、1.78kg、0.96kg。体脂比和体脂肪的增长表现为乡村大于城市,男生大于女生。儿童超重和肥胖检出率也迅速增长,城男、城女、乡男、乡女超重检出率分别由1995年的11.78%、6.22%、2.78%和1.89%上升到2005年的17.86%、10.02%、12.03%和6.46%,肥胖检出率分别由5.00%、3.67%、0.56%和0.33%上升到16.57%、8.16%、9.62%和6.56%,控制儿童肥胖率的形势变得更加严峻。
Trends in skinfold thickness and body composition of urban and rural children aged 7—12 were analyzed by using the data on students physical fitness and health surveillance from 1995 and 2005 in Shandong province.In the past 10 years,the sum of the triceps and subscapular skinfold thickness of these children averaged increases of 7.97mm（urban male）,4.54mm（urban female）,11.42mm（rural male） and 9.48mm（rural female）.The percentage of fat increased on average 3.42%（urban male）,2.07%（urban female）,4.92%（rural male） and 4.35%（rural female）,with body fat increases of 2.34kg（urban male）,1.27kg（urban female）,2.82kg（rural male） and 2.30kg（rural female）.Lean body mass increased 1.96kg（urban male）,1.42kg（urban female）,1.78kg（rural male） and 0.96kg（rural female）.It was noted that increases of percentage fat and body fat of urban children was larger than that of rural children,and that boys was larger than girls.Because percentage of fat had a significant increase,the prevalent rates of overweight children in this age group showed a rapid increase,from 11.78%（urban male）, 6.22%（urban female）,2.78%（rural male） and 1.89%（rural female） in 1995 to 17.86%（urban male）,10.02%（urban female）,12.03%（rural male） and 6.46%（rural female） in 2005.This increase was also clear in obese children with rates of obesity from 5.00%（urban male）,3.67%（urban female）,0.56%（rural male） and 0.33% （rural female） in 1995 to 16.57%（urban male）,8.16%（urban female）,9.62%（rural male） and 6.56%（rural female） in 2005.
