Overview

Prospective cohort study explores the association between maternal iron intake and infant neurodevelopment, indicating heme iron is critical during late pregnancy.

Key Points

  • Infants of mothers with higher heme iron intake in late pregnancy showed 28% lower risk of non-optimal cognitive development.
  • Each unit increase in maternal heme iron intake reduced non-optimal cognition risk by 35%, according to adjusted analysis results.
  • Assessment of infant neurodevelopment utilized standardized Bayley scales 12 months post-birth to evaluate cognitive and motor domains.
  • Observations highlight the unique role of maternal heme iron in supporting optimal infant neurodevelopment, with no effects seen from non-heme iron.
