Plasma ferritin and pregnancy outcome

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Clinical Chemistry

Background:

• Plasma ferritin is a key indicator of total body iron stores.
• Low ferritin levels suggest iron deficiency, while high levels can indicate inflammation or infection.
• The relationship between maternal ferritin levels, birth weight, and preterm delivery requires further investigation.

Purpose of the Study:

• To determine the association between plasma ferritin levels and birth weight.
• To investigate the correlation between plasma ferritin levels and preterm delivery.
• To assess the predictive value of ferritin levels at different gestational ages for adverse birth outcomes.

Main Methods:

• Plasma ferritin and hematocrit were measured in 580 indigent Black women at 19, 26, and 36 weeks of gestation.
• Measurements were correlated with birth weight and preterm delivery (<32 and <37 weeks).
• Statistical analyses, including regression, were used to control for confounders.

Main Results:

• Hematocrit levels did not correlate significantly with birth weight or preterm delivery.
• High ferritin levels at 26 weeks were significantly associated with preterm delivery (<32 and <37 weeks) and low birth weight (<1500 gm).
• Elevated ferritin levels across all measured gestational ages correlated with lower mean birth weights and increased risk of birth weight <2500 gm.

Conclusions:

• High plasma ferritin levels, especially at 26 weeks gestation, are strongly associated with subsequent preterm delivery.
• Elevated maternal ferritin is linked to lower birth weight.
• These findings suggest that high ferritin may serve as a marker for adverse pregnancy outcomes.
