锌影响生长、发育和生殖。然而，母亲锌营养不良（通常以血浆锌测定）对不良妊娠结局的影响并不一致。在新泽西卡姆登的一个贫穷的城市社区的818名孕妇和妇女的队列中研究了饮食锌对妊娠结局的影响（1985-1990）。在这个样本中锌的摄入量为11.1毫克/天，从怀孕期间平均24小时的饮食回忆确定的水平。与锌摄入量较高的孕妇相比，锌摄入量较低的孕妇（低于或等于6毫克/天，相当于妊娠期推荐膳食摄入量的40%）热量摄入量和多种维生素使用量较低，妊娠期体重增加不足和进入产前护理时缺铁性贫血的发生率较高。低锌摄入量与低出生体重风险增加约两倍相关（
Zinc affects growth, development, and reproduction. However, the effect of poor maternal zinc nutriture, as usually measured as plasma zinc, on poor pregnancy outcome has not been consistent. The influence of dietary zinc on pregnancy outcome was examined in a cohort of 818 pregnant girls and women from a poor urban community in Camden, New Jersey (1985-1990). Zinc intake in this sample was 11.1 mg/day, a level ascertained from averaged 24-hour dietary recalls during pregnancy. Gravidas with low zinc intake (less-than-or-equal-to 6 mg/day, amounting to 40% of the recommended dietary allowance for pregnancy) had lower caloric intake and multivitamin usage as well as a higher incidence of inadequate weight gain during pregnancy and iron deficiency anemia at entry to prenatal care compared with those with higher intakes. A low zinc intake was associated with approximately a twofold increase in the risk of low birth weight (
