Popis: Introduction Patients with gestational diabetes mellitus (GDM) need strict blood glucose control to reduce the incidence of perinatal complications in the mother or infant. The purpose of this study was to investigate whether the glycated hemoglobin (HbA1c) values of GDM patients were affected by β-thalassemia minor and to subsequently discuss the limitations of HbA1c monitoring for blood glucose control. Methods 41 GDM patients with β-thalassemia minor were enrolled to serve as the study group. 93 GDM patients without thalassemia were randomly selected as a control group. Clinical data on the 134 mothers as well as their newborns were retrospectively analyzed. The blood glucose values of the participants at various times during the gestation period were compared between the groups, as were their HbA1c and ferritin levels and iron deficiency rates in late pregnancy (36–38 weeks of gestation). Pearson’s coefficient was calculated to determine the correlations between HbA1c and ferritin in both the study and control groups. Results The study and control groups did not show any significant differences in newborn birth weight, maternal age, maternal pre-pregnancy body mass index (BMI), gestational age, newborn sex, gravidity, and parity. The blood glucose values of the participants at different times during the gestation period also did not differ significantly between the study group and the control group. However, the late-pregnancy HbA1c level (5.23 ± 0.49%) and iron deficiency rate (12.19%) in the study group were significantly lower than those in the control group (5.42 ± 0.43% and 58.06%, respectively); P
