title: Iodine deficiency in district Kinnaur, Himachal Pradesh.
abstract: The state of Himachal Pradesh is a known iodine deficiency endemic region since the last 40 years. The state government is supplying iodised salt to the district since 1970. No recent survey has been conducted on the prevalence of iodine deficiency from the district Kinnaur which is located at an average altitude of 10,000 feet above sea level. A total of 1094 children in the age group of 6-10 years were included in the study and clinically examined. The total goitre prevalence of 6.1% was found in the subjects studied. Urine samples were collected from 226 children and were analysed using standard laboratory procedures. It was found that the percentage of children with < 2 mcg/dl, 2-4.9 mcg/dl, 5-9.9 mcg/dl and 10 and above mcg/dl of urinary iodine excretion (UIE) level was 1.3, 5.8, 10.6 and 82.3 respectively. A total of 242 salt samples were collected and analysed using the standard iodometric titration method. Results showed that almost 90% of the families were consuming salt with an iodine content of 15 ppm and more which is the stipulated level of iodisation of salt. The findings of the study indicate that iodine nutrition is in the transition phase from iodine deficient to iodine sufficient. Findings revealed a need for further strengthening the monitoring of the quality of salt being distributed in Kinnaur to achieve elimination of iodine deficiency.
