Background: Anemia in pregnancy is a serious condition, contributing to maternal mortality, morbidity and fetal morbidity and its prevalence varies between 35-100% in developing countries. This investigation is conducted to survey the correlation of maternal factors and the changes in hemoglobin in pregnant women. Method: In this study, 108 healthy pregnant women with gestational age of 10 to 14 weeks, chosen by cluster random sampling were included. The women were followed in three visits: at the end of the first, second and third trimester. In addition, correlation of Hb concentration with maternal factors including BMI, age parity, hyperemesis, gestational age, pregnancy interval and weight gain was investigated. Results: There was no significant correlation between BMI, parity, pregnancy interval, severe nausea and vomiting and also maternal age with hemoglobin level during pregnancy. Moreover, Multiple regression models showed that adequate maternal weight gain (P<0.009) and high hemoglobin (p<0.0001) in the first trimester were positive predictors and late iron supplementation was negative predictor of hemoglobin in pregnancy (P<0.006). Conclusion: Our data demonstrated that adequate maternal weight gain, high hemoglobin in the first trimester and also late iron supplementation could be as predictors in clinical settings in this query.
