摘要
目的了解北京市2岁以内婴幼儿出生时营养、母乳喂养与辅食添加状况,为政府制定儿童营养政策提供依据。方法采取分层整群随机抽样方法,于2002年8至11月在北京市18个区县进行抽样调查。在取得知情同意的情况下,对422名2岁以内婴幼儿的家长进行面对面询问调查。结果北京市平均婴儿出生体重为3325g,低体重出生率和巨大儿出生率分别为2.8%和13.0%;4月龄内婴儿母乳喂养率、混合喂养率和人工喂养率分别为56.6%、33.9%和9.5%,城区混合喂养率明显高于郊区;婴幼儿平均断奶月龄为7.4个月;6月龄及以上婴幼儿的辅食添加率为99.4%,城区和郊区婴幼儿各类辅食的添加顺序一致,但郊区婴幼儿的辅食添加时间晚于城区,且蔬菜水果、水产品、食用油的添加频率低于城区。结论北京地区新生儿体格发育良好,应在社区加强婴幼儿喂养的健康教育,提高母乳喂养率,适当延长母乳喂养时间,并适时添加各类辅食。
