Screening and Supplementation for Iron Deficiency and Iron Deficiency Anemia During Pregnancy: US Preventive Services Task Force Recommendation Statement.
Iron deficiency is the leading cause of anemia during pregnancy. According to survey data from 1999 to 2006, overall estimated prevalence of iron deficiency during pregnancy is near 18% and increases across the 3 trimesters of pregnancy (from 6.9% to 14.3% to 28.4%). An estimated 5% of pregnant persons have iron deficiency anemia. ⋯ The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for iron deficiency and iron deficiency anemia in pregnant persons to prevent adverse maternal and infant health outcomes. (I statement) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of routine supplementation for iron deficiency and iron deficiency anemia in pregnant persons to prevent adverse maternal and infant health outcomes.

In 2015 the US Preventive Services Task Force (USPSTF) found insufficient evidence to assess the balance of benefits and harms of routine screening and supplementation for iron deficiency anemia during pregnancy. ⋯ Routine prenatal iron supplementation reduces the incidence of iron deficiency and iron deficiency anemia during pregnancy, but evidence on health outcomes is limited or indicates no benefit. No studies addressed screening for iron deficiency or iron deficiency anemia during pregnancy. Research is needed to understand the association between changes in maternal iron status measures and health outcomes.
