Introduction: On average, 7% of all newborns have a birth weight of less than 2,500 grams. One of the most important causes of low birth weight babies is maternal anemia during pregnancy. This study investigates the relationship between maternal hemoglobin level and birth weight. 
Methods and Materials: This cross-sectional study was performed on prim gravid women. Maternal information such as age, body mass index (BMI) and hemoglobin concentration in the first and third trimesters and then birth weight were recorded. Data were analyzed statistically by SPSSv18 software and Pearson regression and linear logistics tests.
Results: In this study, 160 prime women with a mean age of 17-43 years were studied. The mean hemoglobin concentrations in pregnant women in the first and third trimesters were (range 7.5-5.5) and (range 7.15-7.1), respectively, 21.9% in the first trimester and 16.3% in the third trimester was anemic. The birth weight range of all infants was 5000-900 g and the average birth weight of LBW infants was in the range of 1800-900 g. 17 infants (10.6%) were underweight (LBW), 135 (84.4%) were normal and 8 (5%) were macrosomic. There was a significant positive relationship between maternal hemoglobin concentration in the first and third trimesters with birth weight (P = 0.0001).
Conclusion: It seems that low maternal hemoglobin levels are associated with low birth weight and LBW. Therefore, special attention to maternal hemoglobin levels during pregnancy and its control reduces the prevalence of LBW. Therefore, paying attention to nutrition and controlling iron levels in pregnant women is very effective in ensuring the health of their babies.
