“…As indicated by Bahl et al (1994), Goldenberg et al (1995), Neggers et al (1990) and Scholl et al (1993) a signi®cant positive association was observed between serum zinc concentrations and neonatal birth weight (r 0.3027). Bahl et al (1994) found serum zinc values of 10.1 AE 1.9 mmolaL in mothers whose newborns weighed 3000±3500 g at birth, and 10.8 AE 1.3 mmolaL in those who weighed more.…”

Zinc levels in maternal milk: the influence of nutritional status with respect to zinc during the third trimester of pregnancy

et al. 1997

Objective: To study the relationship between nutritional status with respect to zinc during the third trimester of pregnancy and levels of the same mineral in transition milk (days 13 and 14 of lactation) and mature milk (day 40 of lactation). Design: Longitudinal study. Subjects: A group of 57 healthy, lactating mothers aged between 18 and 35 y (27 AE 3.7) whose pregnancy and labour were attended by the Department of Obstetrics and Gynaecology of Cuenca INSALUD Hospital, Spain. Interventions: Zinc intake during the third trimester was determined by recording the consumption of foods over a ®ve day period and by registering zinc provided by dietary supplements. Zinc levels in maternal serum during this stage of pregnancy, and in transition and mature milk, were determined by atomic absorption spectroscopy. Results: During pregnancy all subjects showed zinc intakes lower than those recommended. Only one pregnant subject took a supplement that provided extra zinc (1 mgad). Subjects with an intake of lower than 50% of that recommended (L) (43.9%) showed signi®cantly lower serum and mature milk zinc levels than did those with higher intakes (H) (56.1%) [12.0 AE 1.5 mmolaL and 28.7 AE 6.2 mmolaL compared to 13.3 AE 2.6 mmolaL and 33.1 AE 8.0 mmolaL respectively]. 56% of L subjects and 28.6% of H subjects showed serum zinc levels of less than 12.2 mmolaL. 8% of L subjects and no H subjects showed less than 11.5 mmolaL of zinc in maternal milk. Conclusions: The diet conditions maternal serum zinc levels during pregnancy and those of milk during lactation. Though all subjects showed intakes clearly below those recommended, low levels in serum or milk were much rarer. These results support the idea that there is a need to reset the limits of normality for serum and milk zinc levels. Further work in this area may con®rm that the present recommended intakes of zinc be modi®ed.

“…Of 38 studies reporting associations between maternal plasma or serum zinc concentration and fetal growth (expressed either as birth weight or as some definition of adequacy, eg, birth weight > 10th percentile), 18 studies (19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) reported positive associations, whereas 20 studies (10, 36-54) reported negative associations. Of the 14 studies conducted in populations in developing countries, 9 reported positive associations (8,20,22,26,27,28,(32)(33)(34)) and 5 reported negative associations (37,39,40,42,48). Various reasons for these differences in associations can be postulated, including differences in 1) timing of the assessment (blood draw) during pregnancy and the effects of hemodilution, 2) laboratory methods and quality, 3) sample size and the potential for influential values to drive associations, and 4) the underlying zinc nutriture of the populations.…”

Mild-to-moderate zinc deficiency may be relatively common worldwide, but the public health importance of this degree of zinc deficiency is not well defined. The purpose of this review was to provide a conceptual framework for evaluating the public health importance of maternal zinc deficiency as it relates to fetal growth and development, complications of pregnancy, labor and delivery, and maternal and infant health. The mechanisms through which zinc deficiency could influence health outcomes are well described. The results of experimental studies conducted in animal models have motivated concern about the potential health effects of mild-to-moderate maternal zinc deficiency. Observational studies in human populations have produced strong associations between poor maternal zinc status and various indicators of poor pregnancy outcome, but supplementation trials have not produced strong, or even consistent results. Supplementation trials are needed to define the public health importance of maternal zinc deficiency worldwide. Am J Clin Nutr 1998;68(suppl):499S-508S. KEY WORDSMaternal zinc deficiency, pregnancy, child health, survival, supplementation, parturition, immunology, development INTRODUCTIONIn the past 20 y, much progress has been made in the area of child survival worldwide (1). Improvements in health care, water and sanitation, as well as socioeconomic development have substantially reduced the risks of childhood mortality. In many countries, a child's risk of dying during the first year of life remains high, but because efforts to prevent causes of infant death during the postneonatal period are becoming more and more successful, an ever-growing percentage of infant deaths occurs near the moment of birth. Therefore, efforts to further reduce mortality rates in developing countries will require public health planners and policymakers to place greater focus on understanding and addressing the causes of neonatal and perinatal mortality. Maternal nutritional status, with respect to both macro-and micronutrients, is known to be an important determinant of perinatal and neonatal survival and well-being (2), but maternal nutrition programs in developing countries have focused almost exclusively on the risks to the mother and infant from maternal iron deficiency anemia during pregnancy. Other micronutrients such as zinc may also be important for maternal and infant survival during the critical period surrounding birth, but their importance is less well understood. The purpose of this paper is to provide a background and conceptual framework for evaluating the public health importance of maternal zinc deficiency as it relates to fetal growth and development; complications of pregnancy, labor and delivery; and maternal and infant health and well-being. PREVALENCE OF MATERNAL ZINC DEFICIENCYAlthough severe zinc deficiency is now considered rare, mildto-moderate zinc deficiency may be relatively common throughout the world (3). In general, few data are available on the prevalence of mild to moderate zinc de...
