妊娠期间,胎儿生长发育需要从母体摄取各种营养素,包括糖类、脂肪、氨基酸、维生素及各种元素。而在各种元素中,钙是一种十分主要的元素,孕期中胎儿骨髂等组织的发育以及维持各种细胞的正常功能都需要钙元素。妊娠后半期中,约有25～30g 钙沉积于胎儿骨质中,这就意味着孕期母体需摄入更多的钙以供给胎儿需要。本实验随机选择120例妊娠28～30周,单胎,无合并症孕妇,随机化进入临床对照实验。结果提示,补钙剂组的临床缺钙症状明显改善,各组孕晚期的妊高征发生率无差异。对分娩及新生儿预后无不良影响。因此认为:孕期补充钙剂有益于降低缺钙症状发生。
During pregnancy, fetus growth and development need to take a variety of nutrients from the mother, including carbohydrates, fats, amino acids, vitamins and various elements. In a variety of elements, calcium is a very important element in the fetus during pregnancy, such as bone and iliac tissue development and maintain the normal function of various cells require calcium. In the second half of pregnancy, about 25 ~ 30g of calcium deposited in fetal bone, which means that pregnant mothers need to intake more calcium to feed the fetus needs. This experiment random selected 120 cases of pregnancy 28 to 30 weeks, single child, no complications of pregnant women, randomized into clinical control experiments. The results suggest that calcium deficiency group clinical symptoms of calcium significantly improved, the third trimester of pregnancy-induced pregnancy-induced hypertension no difference in the incidence. No adverse effects on childbirth and newborn outcome. So that: calcium supplement during pregnancy is beneficial to reduce the occurrence of calcium deficiency symptoms.
