Haemoglobin Thresholds in Pregnancy: New Evidence Refines Clinical Risk Assessment
Key Highlights
Medicine · Public Health
A comprehensive meta-analysis of 214 studies using the Burden of Proof framework has identified that even mild deviations from an optimal haemoglobin range in pregnancy are associated with nonlinear increases in the risk of major maternal and neonatal complications. Researchers found that the optimal haemoglobin levels clustered between 109 and 135 g/L, suggesting that current clinical thresholds for anaemia in pregnancy may need refinement. For a physician–public health researcher with extensive experience in clinical epidemiology and vaccine development, this finding is directly actionable, as it provides evidence-based guidance for revising antenatal care protocols to improve maternal and child health outcomes at a population level.
