Association of maternal BMI during early pregnancy with infant anemia: a large Chinese birth cohort.

ABSTRACT:

Background

Infant anemia is prevalent in low- and middle-income countries. Maternal body mass index (BMI) is associated with serum ferritin in cord blood, but as yet has not been linked to infant anemia.
