摘要
目的了解北京市海淀区7～18岁儿童青少年皮褶厚度与肥胖的关系,为中小学生肥胖早期预防与干预提供科学依据。方法采取分层整群抽样,对北京市海淀区3所中学和2所小学7～18岁1007名儿童青少年进行皮褶厚度测量,按照WGOC推荐的中国儿童青少年超重、肥胖分类标准将人群分为正常组、超重组及肥胖组,采用均数比较、Pearson相关分析、t检验等统计学方法。结果在控制了年龄、性别影响后,7～18岁儿童青少年的腹部皮褶厚度、髂前皮褶厚度、肩胛皮褶厚度、上臂皮褶厚度与BMI呈高度正相关,偏相关系数r分别为0.736,0.761,0.817,0.684(P值均<0.01)。皮褶厚度值均为肥胖组>超重组>正常体重组,差异均有统计学意义(P值均<0.05)。结论海淀区7～18岁儿童青少年皮褶厚度均值在7～9和10～12岁突增,从10～12岁以后男女皮褶厚度增长幅度逐年递减。肥胖组与正常组的皮褶厚度值差异均有统计学意义。
Objective To understand relationship between skin-fold thickness and obesity among 7 - 18 years old children and adolescents in Haidian District of Beijing, and to provide scientific basis for early prevention and intervention of obesity among primary and secondary school students. Methods By using stratified cluster sampling method 1 007 children and adolescents aged 7 - 18 years from 3 middle schools and 2 primary schools in Haidian District of Beijing were selected and measured skin-fold thickness. And they were divided into normal group, overweight and obese groups according to chinese children and adolescents overweight and obesity classifcation standard recommended by WGOC. Mean comparison, Pearson correlation analysis, t test and other statistical methods were used. Results After controlling impact from age and gender, abdominal skin-fold thickness, forehead skin-fold thickness, scapular skin-fold thickness and upper arm skin-fold thickness of 7 - 18 years old children and adolescents were highly positive correlated with BMI, partial correlation coefficient were 0. 736, 0. 761, 0. 817 and 0. 684 （ P 〈 0. 000 ）. All skin-fold thickness were obese group 〉 overweight group 〉 normal weight group, and the differences were significant （ P 〈 0. 05 ）. Conclusion Average skin-fold thickness of 7 - 18 years old children and adolescents in Haidian District suddenly increased at the age of 7 -9 and 10 - 12, and after 10 - 12 the increase extent declined year by year. In obese group and normal group, there are significant differences between different genders in skin-fold thickness.
