对南京地区86名妊娠晚期孕妇膳食锌摄入情况进行调查,同时分析其血锌等指标。结果表明妊娠晚期孕妇平均每日锌摄入量为11.64±3.65mg,其中8.1％低于推荐摄入量(RDA20mg/d)标准的1/3;63％低于RDA标准的2/3。其母血锌及子代的出生体重间未发现有明显差別,出生婴儿也无明显体格异常,认为母亲孕期锌营养的标准,应根据母子代谢的需要而予以进一步确定。
To investigate the dietary zinc intake of 86 pregnant women in the third trimester of pregnancy in Nanjing, the indexes of blood zinc and other indexes were analyzed. The results showed that the average daily intake of zinc in pregnant women in the third trimester was 11.64 ± 3.65 mg, of which 8.1% was lower than 1/3 of the recommended intake (RDA20mg / d) and 63% lower than 2/3 of the RDA. The maternal blood zinc and offspring of birth weight did not find any significant difference between the birth of the baby nor significant physical abnormalities that the mother’s zinc nutrition during pregnancy standards should be based on the needs of the mother and the child to be further identified.
