Assessment of physical growth in patients with beta thalassemia major in Mashhad

Thalassemia represents a group of recessively inherited hemoglobin disorders and is characterized by reduced synthesis of beta globin chain. The homozygous state results in severe anemia which needs regular transfusion every 3-4 weeks. Frequent blood transfusion can lead to iron overload which may result in growth retardation in thalassemic patients. In this descriptive-cross sectional study، we measured weight and height of 100 patients with beta thalassemia major within the age range of 2-18 years old who were under follow up in Dr. Cheikh Hospital. The results were then compared with the control group (340 healthy children). The mean and standard deviation values of hemoglobin and ferritin were 8. 5 ± 1. 5 g/dl and 2183 ± 525 ng، respectively. Short stature was seen in 53. 4% of girls and 56. 4% of boys. Short thrunk was reported in 73. 3% of girls and 74. 5% of boys. Underweight was reported in 48. 9% of girls and 52. 7% of boys. Growth retardation is common in thalassemic patients. Therefore، height and weight should be routinely and frequently assessed and in the case of growth retardation the cause should be investigated. Common causes of growth retardation are chronic anemia، hypoxia، and iron overload.
