| ABSTRACT: Background: There is disagreement among studies regarding the association between maternal hemoglobin levels and pregnancy outcome. This includes low birth weight, increase placental weight and a high placental -to-birth weight ratio. Objectives: The aim of this study was to determine the relationship between the concentration of maternal hemoglobin for 37-42 weeks pregnant women with neonatal birth weight, placental weight, and placental to birth weight ratio. Patients and methods: five hundred pregnant women in labour were enrolled in this cross-sectional study from 1st February 2024 to 30th of August 2024 at the labour ward of Maternity Teaching Hospital, Erbil city, Kurdistan region, Iraq. Data about demographic characteristics were obtained, maternal hemoglobin was tested, placenta and baby were weighed separately after birth, and placental weight to birth weight were estimated. Results: Fifty-two percent of the study group was anemic, with 1% having moderate anemia and 51% having mild anemia. Anemic women had a mean placental weight of 753.9 ± 94.1 g. Significant differences were found in placental weight and birth weight between anemic and non-anemic groups. The placental-to-birth weight ratio (PWR) was highest in pregnancies with maternal hemoglobin <110 g/L (p < 0.05). Conclusion: Neonatal birth weight decreases with lower maternal hemoglobin levels. Placental weight and the placental-to-birth weight ratio were higher in pregnancies with low maternal hemoglobin compared to those with normal levels. | ||
