对全国八个地区3916名孕妇、乳母及青年妇女进行了膳食锌营养状况评价,比较了各地区的差别,并就锌缺乏对胎、婴儿所产生的影响进行了研究。结果表明:3916名孕妇、乳母及青年妇女锌摄入量均值为6.5±2.3～9.0±3.6mg/d,被调查者中仅有7.2％人达到我国RDA的三分之二以上。膳食锌主要来源于谷类食物(77％左右),且地区间差别显著。经单相关和逐步回归分析,母亲锌摄入量与胎儿的生长发育、新生儿出生体重有着密切关系、妊娠过程中母体膳食锌摄入量对胎儿生长发育有直接的影响。
Nutritional status of dietary zinc in 3916 pregnant women, lactating women and young women in eight districts of the country were evaluated. The differences among different regions were compared and the effects of zinc deficiency on births and infants were studied. The results showed that the average zinc intake of 3916 pregnant women, nurse and young women was 6.5 ± 2.3 ~ 9.0 ± 3.6mg / d, and only 7.2% of the respondents reached more than two thirds of our RDA. Dietary zinc is mainly derived from cereals (about 77%), with significant differences between regions. By single correlation and stepwise regression analysis, the zinc intake of mothers is closely related to the growth and development of the fetus and the birth weight of the newborn. The dietary intake of zinc in the mother’s body during pregnancy has a direct effect on the growth and development of the fetus.
