Waist circumference and its correlation with height and weight among children aged 8-12 years in Ji'nan city

目的探讨山东省济南市8～12岁儿童腰围的分布特征及其与年龄、身高、体重和体质指数的相关性。方法采用分层随机抽样方法,随机抽取山东省济南市全日非寄宿制大、中、小型6所小学1 362名8～12岁学生,进行腰围、身高和体重测量分析。结果济南市8～12岁小学生各年龄组男生腰围、腰高比均大于女生(P<0.05),且男、女生腰围均随年龄增长而增大(P<0.01);相关分析结果表明,男生腰围与年龄(r=0.366)、身高(r=0.599)、体重(r=0.909)和体质指数(r=0.889)均呈正相关;女生腰围与年龄(r=0.376)、身高(r=0.560)、体重(r=0.891)和体质指数(r=0.871)均呈正相关;男生腰高比与身高(r=-0.226)呈负相关,与体重(r=0.718)和体质指数(r=0.868)均呈正相关;女生腰高比与身高(r=0.088)、体重(r=0.620)和体质指数(r=0.835)均呈正相关。结论济南市8～12岁儿童男生腰围大于女生;腰围与年龄、身高、体重和体质指数有关;腰高比与身高、体重和体质指数有关。

Objective To study the distribution of waist circumference and its correlation with age,height,weight,and body mass index in children between 8 and 12 years in Ji＇nan city.Methods We selected 6 schools by stratified random sampling.There were 1362 students aged 8-12 years in the survey.We measured waist circumference,height and weight of the children.Results The waist circumference and the ratio of waist to height of the boys were significantly higher than that of the girls（P 0.01）.The waist circumference was positively correlated with age（r=0.366）,height（r=0.599）,weight（r=0.909）,and body mass index（r=0.889） in the boys and positively correlated with age（r=0.376）,height（r=0.560）,weight（r=0.891）,and body mass index（r=0.871） in the girls.The waist to height ratio was positively correlated with weight（r=0.718） and body mass index（r=0.868）,but negatively correlated with height（r=-0.226） in boys and was positively correlated with height（r=0.088）,weight（r=0.620）,and body mass index（r=0.835） in girls.Conclusion Waist circumference is significantly higher in boys than that of in girls and correlates with age,height,weight,and body mass index.Waist to height ratio correlates with height,weight,and body mass index.
