Daily Versus Alternate Day Iron Supplementation for the Treatment of Iron Deficiency Anemia in Pregnancy
Study Details
Study Description
Brief Summary
The target population for our study is pregnant women in the first or second trimester with a diagnosis of iron deficiency anemia. If a subject is eligible, written consent will be obtained by person to person contact. Eligible participants will be randomized to receive either daily oral iron supplementation or every other day oral iron supplementation.

Phase 4 |
Detailed Description
Eligible pregnant women in the first or second trimester who carry a diagnosis of iron deficiency anemia as defined by the American College of Obstetrics and Gynecology will be approached, consented, and randomized to receive either daily oral ferrous sulfate (325mg) supplementation or every other day oral ferrous sulfate (650mg). Participants will undergo a phone survey 2-4 weeks after starting the study to assess for side effects. Participants will continue routine care and surveillance of iron deficiency in pregnancy until the end of pregnancy.

Outcome Measures
Primary Outcome Measures
- Difference in hemoglobin levels from enrollment to end of study [Baseline and again 8-9 months later (third trimester of pregnancy)]
Hemoglobin levels will be assessed by blood draw upon enrollment and again in the third trimester of pregnancy
- Change in hematocrit in the third trimester after treatment [Baseline and again 8-9 months later (third trimester of pregnancy)]
Hematocrit levels will be assessed by blood draw upon enrollment and again in the third trimester of pregnancy
Secondary Outcome Measures
- Gastrointestinal side effects after 2-4 weeks of treatment [2-4 weeks after enrollment]
Gastrointestinal side effects with treatment will be assessed by telephone survey using a validated questionnaire.
- Complete blood count in the third trimester [8-9 months after enrollment (third trimester of pregnancy)]
Complete blood count indices will be assessed by blood draw upon enrollment and approximately monthly until delivery
- Serum ferritin at time of enrollment [Baseline only at time of enrollment]
Serum ferritin will assessed by blood draw at time of enrollment.
- Total iron binding capacity at time of enrollment [Baseline only at time of enrollment]
Total iron binding capacity will assessed by blood draw at time of enrollment.
- Transferrin at time of enrollment [Baseline only at time of enrollment]
Transferrin levels will assessed by blood draw at time of enrollment.
- Number of participants who receive intravenous (IV) iron supplementation [At completion of study, on average after 9 months]
By chart review, we will determine if the subject received parental (IV) iron supplementation as part of the treatment for iron deficiency anemia
- Number of participants who receive a blood transfusion [At completion of study, on average after 9 months]
By chart review, we will determine if the subject received a blood transfusion as part of the treatment for iron deficiency anemia
- Postpartum hemoglobin [At completion of study, on average after 9 months]
Hemoglobin levels after delivery will be recorded (if obtained as part of regular postpartum care)
- Postpartum hematocrit [At completion of study, on average after 9 months]
Hematocrit levels after delivery will be recorded (if obtained as part of regular postpartum care)
- Neonatal weight at delivery [At completion of study, on average after 9 months]
The weight of the baby (in grams) will be determined by chart review at the end of enrollment
- Level of neonatal bilirubin at birth [At completion of study, on average after 9 months]
Neonatal hyperbilirubinemia will be reviewed and recorded by chart review
- Neonatal Apgar scores [At completion of study, on average after 9 months]
Neonatal Apgar scores will be reviewed and recorded by chart review. The Apgar score is a method used to describe a newborn's status at birth and response to resuscitation. The Apgar score comprises five components: 1) color, 2) heart rate, 3) reflexes, 4) muscle tone, and 5) respiration, each of which is given a score of 0, 1, or 2. The range of scores is 0 to 10. Higher scores indicate reassuring newborn status.
- Number of newborns who are admitted to the Neonatal Intensive Care Unit (NICU). [At completion of study, on average after 9 months]
The need for Neonatal Intensive Care Unit (NICU) Admission, will be assessed
- Weight class at time of enrollment [Baseline only at time of enrollment]
At time of enrollment the weight of the subject will be assessed and assigned a weight class using the World Health Organization weight classification
