作者测定了101名正常孕妇不同孕期血中及胎儿脐血中血清总蛋白、白蛋白、运铁蛋白、血红蛋白、钙、铁、锌,铜的含量,并在采血的同时作了膳食调查。结果提示,随着妊娠的进展,母体血清总蛋白、血清铁、锌和血红蛋白含量下降。如将母血中上述指标与胎儿脐血中相应指标的含量作单相关分析,可见孕后期母血中铁、钙和锌与脐血中含量呈正相关。用逐步回归分析,与母血总蛋白关系最密切的膳食因素为总热量;与血钙、血锌、血铁关系最密切的膳食因素分别为总钙摄入;动物性食品量;肉、鱼类食品与维生素C摄入量,血红蛋白则与食物中总热能和血清铁关系最大。单相关分析指出血清钙与膳食中总蛋白质摄入,动物性钙,乳类食品摄入量也呈正相关。
The authors measured the levels of serum total protein, albumin, transferrin, hemoglobin, calcium, iron, zinc and copper in blood and fetal umbilical cord blood of 101 normal pregnant women at different stages of pregnancy. The results suggest that with the progress of pregnancy, maternal serum total protein, serum iron, zinc and hemoglobin levels decreased. If the above indicators of maternal blood and fetal cord blood corresponding index content for single correlation analysis shows that maternal blood in postpartum iron, calcium and zinc content was positively correlated with cord blood. By stepwise regression analysis, the dietary factors that are most closely related to maternal blood total protein are total calories; the dietary factors that are most closely related to blood calcium, blood zinc and blood iron are total calcium intake, animal food quantity, meat and fish Food and vitamin C intake, hemoglobin and food in total heat and serum iron has the greatest relationship. Single-correlation analysis showed that serum calcium was positively correlated with dietary intakes of total protein, animal calcium and milk food intake.
