Cord blood haemoglobin and ferritin concentrations in newborns of anaemic and non-anaemic mothers in Lagos, Nigeria.

ABSTRACT: BACKGROUND: Pre-delivery haemoglobin and serum ferritin concentrations of anaemic and non-anaemic mothers were determined, and cord blood haemoglobin and serum ferritin concentrations of their newborns were compared. This is to establish the mean values for pre-delivery haemoglobin and serum ferritin concentrations of anaemic and non-anaemic mothers and the cord blood haemoglobin and serum ferritin concentrations of their newborns at term. MATERIALS AND METHODS: A case-control study was done involving 142 pregnant women and their newborns. They were divided into two groups - the anaemic group (n = 65) and the non-anaemic (n = 77) group. Five millilitres of blood was collected from each woman and 2 ml was collected from the cord of their newborns into ethylenediaminetetraacetic acid (EDTA) bottle and plain bottle for full blood count analysis and ferritin assay, respectively. RESULTS: The mean pre-delivery haemoglobin concentrations of the women in anaemic group and non-anaemic group were 9.5 ± 1.01 g/dl and 12.15 ± 1.07 g/dl, respectively, and their mean serum ferritin concentrations were 64.45 ± 138.76 ?g/l and 32.83 ± 35.36 ?g/l, respectively. The mean cord blood haemoglobin concentrations for anaemic and for non-anaemic groups were 12.54 ± 2.54 g/dl and 13.44 ± 2.23 g/dl (P = 0.02), respectively, and the mean cord blood serum ferritin concentrations (non-anaemic, 69.38 ± 78.88 ?g/l; anaemic, 7.26 ± 115.60 ?g/l) (P = 0.00) were higher in the newborns of non-anaemic than of anaemic mothers. Significant association was found between maternal anaemia and cord blood ferritin concentrations (P = 0.025). CONCLUSION: Maternal anaemia has significant effects on cord blood haemoglobin and serum ferritin concentrations.

Project description:BACKGROUND:Lead toxicity is a cause of intellectual disability in children and majority of affected children live in developing countries. Its adverse effect on pregnancy outcome has also been documented. OBJECTIVES:To assess the relationship between maternal blood lead levels and umbilical cord blood lead levels in their corresponding newborn infants; to determine factors associated with high blood lead levels and the pregnancy outcome in participants. MATERIALS AND METHODS:This was a cross-sectional descriptive study carried out at a tertiary Teaching Hospital, Lagos, Nigeria. Four hundred and forty pregnant women and their respective newborns delivered at the study centre. Blood samples were obtained from the mothers and umbilical cord of the newborns at delivery and analysed by atomic absorption spectrophotometry. Socio-demographic and obstetric data was obtained by questionnaires administered to the mothers. The anthropometric measurements of the babies were taken at birth and clinical data recorded. Main outcome measures were blood lead levels in mother and baby pair, socio-demographic factors, birth weight, gestational age, length, occipito-frontal circumference. RESULTS:The median maternal and umbilical blood lead level was 64.3?g/dl and 39.2?g/dl respectively. The levels were above 5?g/dl in 75.6% and 66.8% of mothers and umbilical cord respectively. There was a strong positive correlation between the maternal and umbilical cord blood lead levels (rs = 0.80). Use of calcium supplements during pregnancy was significantly associated with a lower maternal blood lead level (p = 0.010) while recent painting and renovation of residential accommodation were associated with a higher umbilical cord blood lead level (p = 0.025). There were no statistically significant associations between the maternal and umbilical cord blood lead levels and the gestational age and anthropometry of the newborns at birth. CONCLUSIONS:The blood lead levels in newborns of women residing in Lagos, Nigeria are high and administration of antenatal calcium is associated with lower blood lead levels.
