北京市儿童青少年副食摄入现况评估

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20867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等级均归为射周重置，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。
