摘　　要：目的:对北京市儿童青少年副食摄入现况进行评估,阐述营养转型期儿童发展与副食关系内在规律性,为决策提供依据。方法:资料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样本,截取3—18岁儿童青少年20 867人,约男女各半。儿童青少年超重(含肥胖)、肥胖以国际肥胖专家组(IOTF)之BMI界值进行界定。副食为10类,即:肉类、豆制品、海产品、奶类、蔬菜、水果、油炸食品、洋快餐、汤、软饮料;每类按5等级,由家长填写;将问卷中5等级均归为次/周重置,进行加权评估与Z评估。结果:副食加权评分年龄别构成比变化趋势显示,肉和水果频次构成相似,呈"较多-渐少-再渐多"过程,蔬菜递增、奶类递减;男生肉频次较高,而女生水果频次较高;城市肉、奶频次较高,而农村蔬菜、汤频次较高;正常儿童较超重与肥胖者肉频次略低,且蔬菜频次略高;重要副食搭配Z值图形呈对称交叉蝶状,负性相关多于正性相关。对体格类型影响显示多项Z值互逆。结论:副食频次研究能够反映营养转型期不同群体儿童青少年摄入状况,众多类副食搭配Z评分负相关,不同体格儿童之副食谱存在显著性差异。[Objective]To assess the children grocery intakes in Beijing to afford basic evidences of nutritional strategy.
