This study aimed to compare the prevalence of congenital hypothyroidism between Nahavand in the west of Iran and Kashmar in the east of Iran during the years 2016 2017. Methods: This is a cross-sectional descriptive study on neonates born in April 2016 to March 2018 in two cities of Nahavand and Kashmar. A few drops of blood from a baby's heel in 3 5 birthdays on a special filter paper (S & S903) became blood samples from the pelvic floor were filtered and dried. The valuation of the samples was performed by the enzyme linked immunosorbent assay method by evaluating the thyroid stimulating hormone. Premature infants, underweight (less than 2,500 grams), a weight of over 4 kg, multiple births, or newborns requiring blood transfusions or any newborn needed to be retaken to the test after two weeks. Results: In the city of Nahavand, the incidence of neonatal hypothyroidism in the years 2016 and 2017 were 6.7 and 9.09 per 1,000 live births. And for the city of Kashmar, this number increased to 5.6 and 4.3 per 1,000 births in 2016 and 2017, respectively. The mean rate of participation in the screening program in the first 3 5 days of birth in Nahavand during two years was 2016 and 2017 to 78.7% and in Kashmar about 94%, which indicates the higher participation of Kashmar. In the city of Nahavand, 64.6% of cases of hypothyroidism reported in boys' neonates and 51.5% of male children in the Kashmar city. Conclusion: The results of our survey indicates that the prevalence of hypothyroidism is high in both Kashmar in eastern Iran and Nahavand in western Iran. Especially in Nahavand city of western Iran, where the prevalence of hypothyroidism is higher than global and internal statistics. Further surveys are required to elucidate the role of iodine deficiency and family marriage in the hereafter.展开更多
