It remains unclear how the relationship between anemia and maternal and child outcomes may vary based on the cause of anemia and potential implications for anemia cutoffs. Additional research is required to better understand the association of maternal Hb with maternal outcomes (e.g., depression) and long‐term child health outcomes (e.g., cardiovascular outcomes, diabetes, and child development). Few studies report relationships between continuous measures of maternal Hb and health outcomes. Further research is required on the role of maternal preconception Hb and birth outcomes. Few studies provide maternal Hb data during multiple time periods during pregnancy in the same cohort of women. This information is needed to guide potential trimester‐specific cutoff decisions. Limited data are available in high‐risk populations and further research is needed to understand if separate cutoffs are needed (i.e., twin pregnancies). Pooled, high‐quality, individual‐level prospective cohort data are needed to conduct cutoff analysis to inform the reevaluation of Hb cutoffs during pregnancy.
