Stats
The prevalence of iron deficiency was 28%, 51%, and 62% in the first, second, and third trimesters, respectively.
The prevalence of anemia was 18%, 27%, and 33% in the first, second, and third trimesters, respectively.
An increased risk for fetal complications was associated with maternal connective tissue disease (odds ratio [OR], 2.14) and low maternal hemoglobin levels and maternal iron deficiency (ORs, 0.52 and 0.86, respectively).
Lower maternal hemoglobin levels were associated with an increased risk for maternal complications (OR, 1.47).
Patients with connective tissue disease had a lower risk for maternal complications (OR, 0.51).
Mean serum ferritin had no significant impact on maternal complications (OR, 1.02).
