Neonatal Growth, Neurotrophine, Zinc, and Ferritin Concentration in Normal and Iron Deficience Pregnancy: An Observational Analitic Study.

Abstract

BACKGROUND:Anemia in pregnancy was one of the national problems. Insufficient iron deposits before pregnancy and inadequate iron intake during pregnancy could lead to iron deficiency anaemia in pregnancy, followed by iron deficiency in neonates.AIM:This study aimed to assess the molecular relationship of maternal iron deficiency with the function of the neonatal central nervous system to know the cognitive aspects of learning ability of children.METHODS:This study was an observational analytic study with cross-sectional design underwent in RSUP Dr M. Djamil Padang, RSI Ibnu Sina Padang, and RSU BMC Padang. The sample size was 80 pregnant women at term. After a maternal and neonatal physical examination, maternal and umbilical blood samples were obtained to assess maternal ferritin levels and neonates ferritin, neurotrophin and zinc levels using the Enzyme-Linked Immunosorbent Assay (ELISA). Data were analysed using the IBM SPSS Statistics for Windows. The independent sample t-test was performed to assess the relationship for normally distributed data and Mann-Whitney test for abnormal data distribution with significance level p < 0.05.RESULTS:There were differences in mean neonatal ferritin (p < 0.001), neonatal neurotrophin (p < 0.001), and neonatal zinc (p < 0.001) to normal maternal ferritin levels (≥ 15 μg/ml) and low maternal ferritin levels (< 15 μg/ml). The difference in mean neonatal head circumference (0.92; CI95% -0.79-0.98) was associated with neonatal ferritin levels.CONCLUSIONS:The mean neonatal ferritin, neurotrophin, and zinc levels were found lower in iron deficiency maternal. Maternal iron deficiency correlates with neonate growth, iron deficiency, and neurotrophin expression that affected neonate cognition.
