Assessment of relationship between Iron deficiency and preterm labor

Abstract

Preterm labor is important in a predication of neonatal mortality. In united state of America it's relieved that the mortality rate of neonates has direct relation with frequency of low birth weight neonates and preterm labor. Neonates mortality and sever morbidity or both, before 26 th weeks of pregnancy occur in most of neonates and before 24 th. weeks of pregnancy occur approximately in all of them. It is prominent that prenatal care cost considered as national cost, for this reason frequent studied design to decrease this costs, neonatal mortality and preterm labor. The aim of this study is to determine the relation between iron deficiency anemia and preterm labor and Lab finding in iron deficiency anemia and preterm labor too. In this study, at 2005 year, 200 pregnant women in Tabriz Al-Zahra and Taleghani OB hospitals with cooperation of Al-Zahra laboratory undergo a cohort and case control study, all women base on delivery type divided into two groups, one 100 women with term delivery and other 100 women with preterm delivery. Assessment of serum iron, total iron binding capacity (TIBC), Ferritin, hemoglobin and hematocrit were done in all women before delivery. Within the main part of study, we determine the frequency of neonate's gender, weeks of pregnancy and age of mothers. In relation between delivery type (preterm or term) and serum iron, hemoglobin and hematocrit, we came out P_Value equal to <0.001, 0.004 and <0.001, respectively that show pregnant women with preterm delivery have low serum iron, hemoglobin and hematocrit in comparison with women with term delivery, but in relation between serum ferritin and TIBC P_Value was 0.987 and 0.930, respectively that had no statistical significance. In group with preterm labor, 62% of neonates were male and 38% was female. The major part of mother of this group is in third's decade of life. Respectively 31%, 19% and 50% of mother with preterm labor had borne her neonate in 26-30, 31-33 and 34-37 weeks. It seems that relation between iron deficiency anemia in pregnancy and delivery type is deniable. However, to show its relation more studies must be performed in this field. [Nazli Navali.
