Introduction: Iron deficiency anemia (ADI) is the most common cause of anemia in pregnant women that occurs in 15% to 25% of pregnancies. According to WHO report, the prevalence of anemia is 56% in developed countries and 20% in developing countries. This study was performed with aim to evaluate the relation between anemia during pregnancy and birth weight.
Methods: In this retrospective and descriptive-analytic study, the records of 504 pregnant women who were otherwise healthy and free of disease were evaluated. Pregnant women who their pregnancy had led to term live birth during the past 10 years were enrolled to the study by census sampling method. Patients' information were collected with checklist based on their records. Checklist included two sections of personal characteristics of mothers and neonates' weight. Data was analyzed with SPSS statistical software (version 16) and chi-square and independent t tests. PResults: Mean neonatal birth weight was 2942±467 gr. 130 neonates (25.8%) had birth weight Conclusion: Frequency of anemia during the second and third trimester of pregnancy is significantly higher in the mothers of neonates with birth weight <2500 gr than the mothers of neonates with normal weight.
