摘要
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。
The zinc intake of 3916 pregnant and lactating women and the relationship between maternal zinc intake and infant development were investigated. The maternal dietary intake of zinc during pregnancy and lactation was 6.5 ±2.3, -9.0±3.6mg; only 7.2% of the women reached two thirds of Chinese RDA. Cereal was the major source of dietary zinc which accounted for about the 77% of the tatol zinc intake. From the correlation and stepwise regression analysis, it was found that maternal dietary zinc intake during pregnancy was significantly correlated with the fetal development and birth weight. Therefore it was very important to increase zinc intake during pregnancy.
