  The present study was conducted in district Udham Singh Nagar, Uttarakhand state with an objective to assess the status of iodine deficiency amongst school age children (6-12 years).

The clinical examination of the thyroid of each child was conducted. Urine and Salt samples were collected from children.
  
  
  RESULTS
  The Total Goiter Rate (TGR) was found to be 13.2%. The proportion of children with Urinary Iodine Excretion (UIE) level <20, 20-49, 50-99, 100-199 and ≥200 μg/l was found to be nil, 6.0, 21.2, 34.2 and 38.5 percent, respectively. The median UIE level was 150 μg/l. Only 46.7% of the salt samples had stipulated level of iodine of 15 ppm and more.
