Zinc, retinoids and protein interrelationships in the neonate and mother
| Title: | Zinc, retinoids and protein interrelationships in the neonate and mother |
| Author: | Anderson, Diane Marie |
| Description: | The purpose of this investigation was to determine normative blood levels of protein, zinc and retinoids for the healthy, non-smoking mother and her healthy infant at delivery. The interrelationships of the three blood nutrients between mother and infant, within the mother and within the infant were examined. One hundred and one mothers were enrolled into the study. Thirty-four of these mothers and their infants met the study criterion definition of a healthy pregnancy, and adequate blood was drawn for nutrient analysis. The blood nutrients that were quantified included plasma prealbumin, retinol binding protein, zinc, alkaline phosphatase, retinol and beta carotene, and red blood cell zinc. Dietary histories and food frequency questionnaires were obtained from 4 study mothers. Thirty, 24 hour dietary recalls were obtained from the maternal medical records of the health department. The mothers' plasma levels of prealbumin, retinol binding protein, alkaline phosphatase, retinol and beta carotene and red blood cell zinc were significantly greater than their infants' levels for the 34 healthy, mother infant pairs and the total population of mothers and infants (p < 0.001). The infant's plasma zinc level was significantly greater than the mother' s level for the 34 healthy, mother infant pairs and the total population of mothers and infants (p < 0.001) Within the total population of 92 infants, the following plasma nutrients had positive, significant, correlations: prealbumin and retinol binding protein, prealbumin and zinc, prealbumin and alkaline phosphatase, prealbumin and retinol, zinc and alkaline phosphatase, zinc and retinol, and alkaline phosphatase and retinol. The infant also exhibited significant, positive correlations between red blood cell zinc and plasma retinol, and red blood cell zinc and plasma beta carotene. Within the total population of 101 mothers, the following plasma nutrients had positive, significant correlations: plasma levels of prealbumin and retinol binding protein, retinol binding protein and retinol, and prealbumin and retinol. Between the 92 mothers and infants there were significant, positive correlations for red blood cell zinc and plasma retinol and red blood cell zinc and plasma beta carotene the dietary histories, food frequency questionnaires, and 24 hour dietary recalls demonstrated that the mothers' dietary intake was adequate for protein, vitamin A and zinc. Vitamin mineral supplements were taken by all women This investigation provides normative blood nutrient levels of plasma retinol, beta carotene, zinc, alkaline phosphatase, prealbumin, retinol binding protein, and red blood cell zinc for the healthy mother infant population. Limited normative data had existed on these blood nutrients for a well defined healthy perinatal population. Further, the nutrient interrelationships had not been previously examined in the perinatal population. |
