Abstract
OBJECTIVE: To investigate the effects of pre-delivery hematological parameters on birth weight and to compare their relationship with maternal age and parity in women who had taken routine iron supplementation during pregnancySTUDY DESIGN: A retrospective study was conducted among low-risk pregnant women who were delivered at term. Pre-delivery hematological parameters and clinical information were extracted from patient files and compared with birth weights. Women with known hematological disorders, women with the previous history of intravenous iron treatment and the ones who did not regularly use iron supplementation were excluded. RESULTS: All patients (1066) had undergone complete blood testing before delivery. Mean values for hemoglobin, hematocrit, mean corpuscular volume, red blood cell count and red cell distribution width were as follows; 10.9g/dL (±1.4), 34.6 % (±4.3), 84.6fL (±7.8), 4.1g/dL (±0.4), and 14.2 % (±2.5), respectively. When all patients are evaluated, 300 (28%) of them were found to be anemic according to Word Health Organization criteria but not for the former ACOG cut-off, which was 9.5 g/dL. There was no significant association between pre-delivery anemia and birth weight. However, the anemic women group was found to be slightly younger than non-anemic ones according to both criteria.CONCLUSION: Our results documented that younger age was associated with more pronounced anemia before delivery. This study did not show any association between pre-delivery anemia and low birth weight irrespective of maternal age. There is a need for further reports investigating the prognostic importance of hemoglobin reduction during pregnancy for infant birth weight in specific age groups and placental insufficiency related conditions.

Summary
Anemia is the most common hematologic abnormality both in the general population and pregnant women (1). It is documented to be a major public health problem in low and middle-income regions (2). According to WHO, more than 40% of pregnant women worldwide are anemic and in more. Quick Response Code: Access this article online. How to cite this article: Atakul T. Comparison of Birth Weights of PreDelivery Anemic and Non-Anemic Routine Iron Supplemented Pregnant Women. Gynecol Obstet Reprod Med 2020;26(1):[21-24] than 50% of these cases, the reason is iron deficiency (3). The most damaging consequences of anemia occur in this population as increased maternal morbidity and mortality along with neonatal negative effects. Vitamin deficiencies (folate, vitamin B12 or A) infections, chronic diseases, and genetic diseases account for the rest of the underlying causes for anemia in pregnancy
