Iodine nutritional status among neonates in the Solan district, Himachal Pradesh, India

Abstract

Iodine nutrition status amongst neonates can be assessed by estimating thyroid stimulating hormone (TSH). According to WHO, if more than 3 % of the neonates have TSH levels of 5 mlU/l and more in a population, it indicates presence of iodine deficiency (ID). Iodine deficiency is an endemic health problem in Solan district, Himachal Pradesh (HP) state. ID leads to mental retardation, deaf mutism, squint, dwarfism, spastic diplegia, neurological defects and congenital anomalies. The aim is to determine iodine nutrition status of neonates of Solan district. In Solan district, six hospitals/community health centers providing obstetric services and conducting more than 100 deliveries per annum were identified and enlisted. Two hospitals were selected keeping in view of operational feasibility. A total of 683 umbilical cord blood samples of neonates were collected on filter paper and analyzed for TSH. It was found that 63.2 % of the neonates had TSH levels of more than 5 mlU/l indicating iodine deficiency in the Solan district. Iodine deficiency was a public health problem in Solan district, HP.
