β-thalassemia is a prevalent disease in Iran. The adverse effects of anemia on placental and neonatal outcomes have previously been shown. Women require additional iron during pregnancy and the anemia of women with β-thalassemia may adversely affect the neonatal outcome and increase placental abnormalities. In this study, we compared the placental histology and neonatal outcomes among pregnant women with and without β-thalassemia. In this population-based cross-sectional study, 144 pregnant women with β-thalassemia minor (case group) were compared to 142 women without β-thalassemia (control group). Women with singleton pregnancies over 20 weeks of gestation without pregnancy complications, anemia, collagen vascular diseases, or other hemoglobinopathies, all referred to hospitals affiliated to Shiraz University of Medical Sciences from March 2014 to February 2016, were included and maternal and neonatal data were extracted from medical records. After child birth, the placenta was evaluated for macroscopic and microscopic changes. The frequency of LBW was significantly higher in the case group than that in the control group (19.7 vs. 9.7%, respectively) (p =.019). Six in the case group had gross abnormalities of placenta, while none in the control group (p =.03) and the case group had a higher frequency of chorangiosis, calcification, syncytial knot, and umbilical cord position (p <.05). As β-thalassemia increases the chance of placental abnormalities, it is recommended to pay more attention to patients with β-thalassemia, especially during pregnancy, to prevent placental and neonatal adverse outcomes.
