The effect of maternal hemoglobin concentration on fetal birth weight according to trimesters

Abstract

Conclusions: Low hemoglobin concentrations in the first trimester of gestation seem to be associated with low fetal birth weights. Anemia can directly cause poor in utero fetal growth due to inadequate oxygen flow to the placental tissue or it can be an indirect indicator of maternal nutrition deficiency. In both circumstances, this study reveals that treatment of anemia before and in the early stages of pregnancy is directly correlated with better fetal outcomes.
