Impact of Preconception Micronutrient Supplementation on Anemia and Iron Status During Pregnancy and Postpartum: A Randomized Controlled Trial in Rural Vietnam

This study examined how preconception weekly iron-folic acid (IFA) and multiple micronutrient (MM) supplements, compare to folic acid (FA) alone during and shortly after pregnancy in Vietnamese women. Pre-pregnancy IFA or MM led to greater iron stores for both mother and child than did FA alone, but did not have any effect on anemia. More research is needed to examine the causes of anemia and interventions for improving anemia status during pregnancy and postpartum.
