本文调查了1987年7～9月(夏秋季)及1989年2～3月(冬春季)出生的共111名新生儿血清25-羟维生素D(25-OHD)与669名血清维生素A(VA)含量,并调查了1989年2～3月出生的新生儿与其母血清25-OHD及VA含量的关系各47对与42对,结果表明夏秋季出生的新生儿血清25-OHD及VA高于冬春季出生者,血清2-5OHD均值分别为36.98nmol/L与18.93nmol/L,低于正常值(<27.5nmol/L)者分别占43.8％与89.4％,血清VA均值分别为0.7μmol/L与0.54μmol/L,缺乏者(<0.70μmol/L)分别占60.5％与95.8％。产母血清25-OHD含量正常与缺乏者,其子均值分别为21.68nmol/L与15.10nmol/L,P<0.01。产母血清VA与其新生儿含量相关r=0.44,P<0.05。二者含量子皆低于母。提示预防先天性佝偻病及VA缺乏应自母孕末期开始,尤以冬春季最为重要。
A total of 111 newborns with 25-hydroxyvitamin D (25-OHD) and 669 serum vitamin A (VA) -products were surveyed from July to September 1987 (summer and autumn) and from February to March 1989 ) And investigated the relationship between 25-OHD and VA content of newborns born from February to March 1989 in 47 pairs and 42 pairs. The results showed that serum 25-OHD and VA in newborns born in summer and autumn were higher than that in VA In winter and spring, the average serum 2-5OHD values were 36.98nmol / L and 18.93nmol / L, respectively, which were 43.8% and 89.4% lower than the normal values (<27.5nmol / L) L and 0.54μmol / L, respectively (<0.70μmol / L) accounted for 60.5% and 95.8% respectively. Producer serum 25-OHD levels were normal and lack of children, their mean were 21.68nmol / L and 15.10nmol / L, P <0.01. Maternal serum VA and its neonatal correlation r = 0.44, P <0.05. Both contain lower than the child’s mother. Tip prevention of congenital rickets and VA deficiency should start from the end of pregnancy, especially in winter and spring is most important.
