北京市顺义区4～12月龄婴儿膳食中铁摄入量调查

目的了解顺义区4～12个月婴儿膳食营养素铁摄入情况,为合理喂养提供依据。方法采用随机整群抽样方法抽取顺义区农村和城镇地区4～12月龄婴儿266名,对婴儿喂养人进行连续3天(72h)膳食问卷调查。结果 4～5月龄婴儿膳食铁摄入量达到DRIs摄入标准,且城乡婴儿膳食铁摄入量差异无显著性(P>0.05)。6～12月龄农村地区婴儿膳食铁摄入量达到适宜摄入量(AI)人数的比例仅为19.8%,城镇地区达到适宜摄入量人数的比例为36.9%,城镇地区婴儿膳食铁摄入量高于农村地区(P<0.01)。不同组之间的婴儿母乳喂养率无统计学差异(P>0.05)。婴儿膳食铁摄入的主要食物来源为谷类、水果类、蛋类、蔬菜类和肉类。结论无论城镇还是农村,顺义区6～12月龄婴儿膳食营养素铁摄入量明显不足,在鼓励完全母乳喂养至6月龄的同时,应根据婴儿的实际情况适时添加富含铁的辅食。
