Association of Maternal Hemoglobin Concentration With Neonatal Outcomes in Deliveries: A Prospective Cohort Study
By Sahebi L, Dalili H, Babagoli M and 1 others.
Abstract
Objective
Maternal hemoglobin concentration during pregnancy is a key indicator of placental-fetal oxygen delivery and may influence neonatal outcomes. Despite existing evidence, prospective cohort data in the Iranian population remain limited. This study aimed to investigate the association between maternal hemoglobin concentration and neonatal outcomes while controlling for potential confounding factors.
Materials and methods
This prospective cohort study was conducted over a six-month period. A total of 263 eligible mother-neonate pairs were included in the analysis. Maternal hemoglobin concentration was measured at 28 weeks of gestation, and participants were categorized into two groups: Hb < 11 g/dL (anemia) and Hb ≥ 11 g/dL. Neonatal outcomes were investigated in two groups. Statistical analyses were performed using independent t-tests, chi-square tests, and univariate and multivariate linear and logistic regression models, adjusting for gestational age, mode of delivery, parity, maternal conditions, and iron supplementation.
