摘要
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。
Dietary Zinc intake was investigated in 86 healthy women at late pregnancy in Nanjing by 24hr recall diet surveys combined with dietary history. The study revealed an average detary Zinc intake of 11.6 ± 3.65mg/d. Among them 8.1% of the cases had a daily Zinc intake less than 1/3 RDA (Recommended Dietary Allowances, 20mg/d), and 6.3% less than 2/3 RDA. However, both maternal serum Zinc levels and infant birthweights were not different significantly among them.
