Evaluation of Relationship Between Maternal Haemoglobin and Haematocrit with Preterm Labour and Neonatal Weight in Pregnant Women in Sabzevar, Iran During 2014-2015

Background and Aims: Maternal haemoglobin and haematocrit levels in the first, second, and third trimesters are considered as possible risk factors regarding preterm labour (PTL). The present study aimed to evaluate the relation between maternal haemoglobin (Hb) and haematocrit (HCT) levels with low birth weight (LBW) and PTL. Materials and Methods: This cross-sectional study was conducted on 383 pregnant women that were admitted in postnatal ward and gave birth to live neonates. Maternal Hb and HCT levels in the first, second, and third trimesters were obtained from subjects’ medical records. The data were analysed using chi-square test by SPSS software (version 19).Results: A total of 383 pregnant women with the mean age of 25.5 years were participated in this study. There was a significant relation between maternal HCT in the first, second, and third trimesters with LBW (P<0.01). A significant relationship was observed between maternal Hb in the first, second, and third trimesters with the LBW (P<0.01). In addition, a significant relation was reported between maternal HCT with the PTL (P<0.01). There was a significant correlation between maternal Hb in the first, second, and third trimesters with the PTL (P=0.01). Perinatal complication risks in low HCT and the Hb levels in the first trimester were reported higher than those in the second and third trimesters.Conclusion: Based on the findings of this study, it was suggested that maternal anaemia should be diagnosed and treated at any stage of pregnancy in order to reduce the risk of the LBW and PTL.
