对75例健康初孕妇女及其足月健康新生儿进行血清维生素A测定,并与血清蛋白质、血红蛋白、血清铁、铁蛋白、锌等进行综合分析。母亲血清VA为3.06±1.03μmol/L,高于新生儿2.74±1.0μmol/L。夏季母、子血清VA均高于秋季,但无显著性差异。孕母临界性VA缺乏占27％、新生儿占45.3％。其血清VA与血红蛋白、血清铁、血清锌呈显著正相关,与血清铁蛋白无相关性。同时VA与新生儿出生体重、胎盘重量也呈显著相关性。提示VA对铁代谢及胎儿生长发育有重要作用。因此,重视VA对母子健康的研究,对临界VA缺乏者进行干预处理,对优生优育有重要意义。 Serum vitamin A levels were measured in 75 healthy pregnant women and their full-term healthy newborns. The levels of serum vitamin A, hemoglobin, serum iron, ferritin and zinc were analyzed comprehensively. Maternal serum VA was 3.06 ± 1.03μmol / L, higher than neonatal 2.74 ± 1.0μmol / L. Summer mother and child serum VA were higher than the autumn, but no significant difference. Maternal borderline VA deficiency accounts for 27%, 45.3% of newborns. Serum VA was positively correlated with hemoglobin, serum iron and serum zinc, but not with serum ferritin. At the same time VA and birth weight, placental weight also showed a significant correlation. Tip VA on iron metabolism and fetal growth and development have an important role. Therefore, the importance of VA on mother and child health research, the critical VA deficiency intervention, prenatal and postnatal care is of great significance.
