NCT05262634

Brief Summary

The primary aim of this retrospective, monocentric study with two parallel groups is to investigate pregnancy outcome in women with iron deficiency in the first trimester. It compares the pregnancy outcome between pregnant women with an iron deficiency and those without an iron deficiency in the first trimester. The study group are pregnant women with a diagnosed iron deficiency in the first trimester, a total of 227 pregnant women. The control group consists of 486 pregnant women without first-trimester iron deficiency. Matching criteria include parity and maternal age. Data from patient files of pregnant women who were treated in the Women's Clinic, University Hospital Basel between 2017 and 2019 are analyzed.

Outcome Measures

Primary Outcomes (3)

  • Proportion of anemia

    Proportion of anemia in pregnant women with an iron deficiency diagnosed in the first trimester compared to pregnant women with normal hematological parameters and iron status in the first trimester

    one time assessment at baseline

  • Proportion of hemorrhage

    Proportion of hemorrhage in pregnant women with an iron deficiency diagnosed in the first trimester compared to pregnant women with normal hematological parameters and iron status in the first trimester

    one time assessment at baseline

  • Proportion of growth retardation

    Proportion of growth retardation in pregnant women with an iron deficiency diagnosed in the first trimester compared to pregnant women with normal hematological parameters and iron status in the first trimester

    one time assessment at baseline

Study Arms (2)

study group: iron deficiency

Pregnant women with a documented iron deficiency in the first trimester

Other: Data collection (laboratory and obstetric results)

control group: normal iron status

Pregnant women with normal hematological parameters and iron status in the first trimester

Other: Data collection (laboratory and obstetric results)

Interventions

Maternal data: age, pregnancy, parity, singleton or multiple pregnancy, BMI, obstetric history data, and ethnicity. Laboratory chemical results: hemoglobin (Hb), number of erythrocytes, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), number of hypochromic erythrocytes (HRC), erythrocyte distribution width (EBW), ferritin, C reactive protein (CRP). Maternal pregnancy outcomes and complications: Hb before and after delivery, mode of delivery, placenta abruption, preeclampsia/eclampsia, gestational diabetes, gestational cholestasis, pregnancy-induced hypertension, bacteriuria or urinary tract infections, peripartum and postpartum hemorrhage, puerperal infections, uterine subinvolution. Perinatal outcomes: gestational age, birth weight, intrauterine growth retardation, preterm birth, macrosomia, premature rupture of membranes, Apgar score, intrauterine fetal death, pH values, admission to neonatology

control group: normal iron statusstudy group: iron deficiency
