锌作为体内一系列重要酶类的组成部分，对维持孕妇的生理机能有着非同小可的作用，而在过程中，锌也起着不可低估的作用。

近年来的研究发现，锌是一种有益的助产元素。妇女在妊娠期血锌浓度水平的高低，决定着其今后的。曾有人对一批孕妇进行血锌浓度测定，并按其后来的分娩方式分组进行对比研究。结果发现，自然分娩的产妇其妊娠期间血锌浓度平均值最高，需要助产的产妇次之，行吸引器助娩的产妇其血锌浓度又较产钳助产的产妇低，而需行剖宫产的产妇其妊娠期间血锌浓度最低。

锌在人体内的总量不超过3g。对分娩的影响，主要是影响子宫的收缩力。锌可以增强子宫肌细胞有关酶的活性，促进肌细胞收缩，从而把胎儿驱出子宫。因此孕妇缺锌，可造成乏力、，还有增加产后出血等产科并发症的可能。

据测定，妇女在后的第2个月，血中锌含量即开始下降，到妊娠晚期母体血锌浓度较未妊娠的正常妇女低20%左右。可见补锌的重要及必要。动物性食物含锌量较高，而且易吸收。如肉、奶、鱼、蛋、牡蛎等，其中牡蛎和鲱鱼的锌含量甚至超过1000mg/kg以上，可称“含锌食品”之王，应注意选食。
