Effects of Second Trimester Maternal Hemoglobin Levels on Birth Weight and Birth Time

Abstract

Objectives: The aim of our study is to investigate the effects of anemia at the second trimester on birth weight and birth time. Patients and Methods: The medical reports of 1116 pregnant women who attended and delivered at our clinic between January 2005 and October 2007 were analyzed retrospectively. The patients were divided into two groups as having <9 gr/dl hemoglobin or ≥9 gr/dl hemoglobin levels. The gestational and the perinatal outcomes of the normal and anemic groups were compared. Results: The age and the parity were higher in the non-anemic group than in the anemic pregnants. (p=0.03, p=0.001). There was no statistically significant difference in the mode of birth and gestational complications between the two groups. While there was no statistically significant difference in the gestational age at delivery and birth weight, prematurity and oligohydramnios ratios were significantly higher in the anemic group compared to the group with Hb>9 gr/dL (p=0.041, p=0.004, respectively). Conclusion: The anemia of second trimester is related with prematurity and increased rate of oligohydramnios. Iron supplementation should be given during pregnancy to improve pregnancy outcomes. Amaç: Bu çalışmanın amacı ikinci trimester anemisinin doğum ağırlığı ve doğum haftasına etkisini araştırmaktır. Hastalar ve Yöntemler: Ocak 2005 ve Ekim 2007 tarihleri arasında kliniğimizde takip edilen ve doğum yapan 1116 hastanın kayıtları retrospektif olarak incelendi. Hastalar ikinci trimester hemoglobin değerleri <9 gr/dl olanlar ve ≥9 gr/dl olmak üzere iki gruba ayrıldı. Anemik olan ve normal hemoglobin seviyelerine sahip gebelerin gebelik seyri ve perinatal sonuçları karşılaştırıldı. Bulgular: Anemik olmayan grupta yaş ve parite anemik gebelere kıyasla yüksekti (sırasıyla p=0.03, p=0.001). Gruplar arasında doğum şekilleri ve gestasyonel komplikasyonlar açısından anlamlı bir farklılık görülmedi. Ortalama doğum zamanı ve doğum kilosu açısından anlamlı bir farklılık görülmezken ikinci trimester anemisi olan grupta prematurite ve oligohidramnios oranı daha fazla görüldü ve bu fark istatistiksel olarak anlamlı bulundu (p=0.041, p=0.004). Sonuç: İkinci trimester anemisi prematürite ve artan oligohidramnios oranlarıyla ilişkili olabilmektedir. Gebelik sonuçlarını iyileştirmek için gebelik süresince demir desteği yapılmalıdır.
