Pregnancy-induced hypertension (PIH) is a significant cause of low birth weight and maternal and neonatal death around the world. This article reviews work indicating that dietary calcium supplementation can sharply reduce the PIH incidence among pregnant women whose regular diet is calcium-poor. It also describes physiologic conditions prevailing during pregnancy that could explain calcium's major role in PIH--as well as supplemental calcium's great potential for preventing PIH among people with low-calcium diets.
妊娠高血压综合征（PIH）是全球低出生体重以及孕产妇和新生儿死亡的一个重要原因。本文回顾了相关研究，这些研究表明，对于日常饮食中钙含量较低的孕妇，补充膳食钙可大幅降低PIH的发病率。本文还描述了孕期普遍存在的生理状况，这些状况可以解释钙在PIH中的主要作用，以及补充钙在预防低钙饮食人群PIH方面的巨大潜力。
