目的：通过对北京市儿童期成人慢性病流行病学副食频次调查资料的研究,阐明奶制品摄入与儿童青少年体格发展的关联性。方法：数据来自北京市儿童青少年代谢综合征分层随机整群抽样调查,截取3—18岁儿童青少年20867人,约男女各半。10类副食含于家庭问卷填写;标记体量指标Z值、儿童青少年超重以国际肥胖专家组（IOTF）界值进行界定;腹型肥胖以年龄、性别腹围超过90%位界定,进行频次构成比较、卡方检验、双因素方差分析、斯皮尔曼等级相关分析。结果：奶摄入频次随年龄递减,城乡差异显著,城区＂每日都吃＂与郊区＂几乎不吃＂比率明显高;对体格发展影响显示正常体重和高身高的正效应;边缘估计值显示,对体重和BMI于城乡间正常范畴之上3%—5%处呈翻转效应,即城区高频次者多,与BMI负相关;郊区高频次少,与BMI正相关。作为独立变量与体脂含量微弱负相关,呈显著性。结论：北京儿童青少年奶频次摄入城市高于郊区,身高为正促进,体重为城郊作用于正高端扭转,对BMI于〉25后呈相对负梯度效应。

【Objective】 To clarify the relevance between dairy intake and physical development of children and adolescents through food frequency analysis of children chronic disease epidemiology survey.【Method】 The data came from stratified random cluster sampling of survey of children and adolescents with metabolic syndrome in Beijing,interception of 20？867 cases of 3 to 18-year-old children and adolescents,about evenly divided between men and women.A total of 10 groups of grocery food filled out the questionnaire in the family and weight,height,and body mass index（BMI） were marked their Z-score.The children and adolescents were diagnosed overweight by International Obesity Task Force（IOTF） cutoff and central obesity was defined by waist circumference more than 90% by age and sex.Relatively frequency,χ2 test,two-way variance,Spearmen rank correlation analysis were conducted.【Result】 The frequency of intake of milk decreased with age.There was significant difference between urban and rural areas,and eating every day in urban was significantly higher than hardly eat in rural.Impact on the physical development showd the positive effects on the height.Estimated marginal means showed the rollover effect up to 3%—5% of 95%CI on weight and BMI between the urban and suburban areas,namely,a higher intake and lower weight in city,higher intake and higher weight tendency in rural.As an independent variable,milk and diary consumption had a weak negative correlation with body fat content,but was significant.【Conclusion】 The frequency of intake of milk and diary productions of children and adolescents was higher in urban than in the outskirts in Beijing,intake higher is promoting the height,reversely to weight of up 95%CI,and negatively to BMI 25.
