Assessment of Iodine in Salt Samples from North Delhi Schools
Iodine is an essential micronutrient required for normal thyroid function, growth, and development. Iodine deficiency can lead to a variety of health and developmental consequences known as Iodine Deficiency Disorders (IDDs). Realizing the magnitude of the problem and to ensure its prevention by 100% consumption of adequately iodized salt (≥15ppm), National Iodine Deficiency Disorders Control Programme (NIDDCP) is being implemented in India. However, periodic assessment of the salt used is needed to ensure the same. Hence, with the objective of assessment of iodine, household salt samples were collected from students of four schools in North Delhi in October 2019. Awareness programme was also planned among the school children in view of Global Iodine Deficiency Disorders Prevention Day. The iodine content of the salt was estimated by standard iodometric titration method. 10 (10.4 %) salt samples were found to have iodine content < 15 ppm. Reasons for low iodine content in the 10 samples need to be assessed along with the information regarding the type of salt used. Measures need to be taken to ensure 100 % consumption of adequately iodized salt (≥ 15 ppm). Also, such periodic assessment should be undertaken to find out the situation in different schools.
