Maternal Hemoglobin Levels Linked to Major Birth Outcomes in Pregnancy
Key Highlights
Medicine · Public Health · Maternal Health
A major meta-analysis of 214 studies using the Burden of Proof framework found that even mild deviations from optimal hemoglobin levels during pregnancy are associated with nonlinear increases in maternal and neonatal complications. Researchers determined that the optimal hemoglobin range for lowest risk clusters between 109 and 135 g/L, with both mild anaemia and higher levels conferring elevated risk. For a nurse and psychologist focused on prevention and chronic disease, this evidence refines clinical thresholds and underscores the importance of routine hemoglobin monitoring as a modifiable risk factor in antenatal care.
