临床上对妊娠妇女常规补充铁剂十分普遍,但也存在争议。为研究孕期补充铁与叶酸对晚期妊娠妇女血清铜含量的影响,选择妊娠33～35周,常规孕期检查的妇女57例为研究对象,随机分为两组。第一组27例,平均年龄25岁,孕期未补充或未规则补充铁与叶酸;第二组30例,平均年龄26岁,自妊娠11～15周起每日规则摄入亚铁盐0.84mmol、叶酸1.13μmol,每周服药不少于6天。以上研究对象无内科及产科合并症,亦无服用其它药物及营养药品史。采静脉血,分别测定血清铜、铁、转铁蛋白及血红蛋白浓度。
Clinically, pregnant women are routinely supplemented with iron, but there is also controversy. In order to study the effect of iron and folic acid supplementation during pregnancy on serum copper levels in pregnant women of late pregnancy, 57 women who were checked during routine pregnancy were selected as study subjects from 33 to 35 weeks of gestation and were randomly divided into two groups. The first group of 27 cases, the average age of 25 years of age, pregnancy did not supplement or irregular iron and folic acid supplementation; the second group of 30 patients, mean age 26 years old, from 11 to 15 weeks of gestation daily intake of ferrous salts 0.84mmol , Folic acid 1.13μmol, taking less than 6 days a week. The above subjects did not have medical and obstetric complications, nor did they take other medications and nutritional drugs. Venous blood was collected, respectively, serum copper, iron, transferrin and hemoglobin concentration.
