Deficiency of iodine can cause physical and mental retardation cretinism abortions stillbirth deaf mutism squint amp various types of goitre. Methodology A community ndash based cross section survey was undertaken during the February-March 2019 in Tumakuru district of Karnataka to find out prevalence of goitre estimate urinary iodine excretion in 6-12 years old school children and household salt iodine concentrations. 2875 school children aged 6-12 years were examined for goitre. Urine samples of 270 childrenwere collected for estimation of urinary iodine using Sandell-Kolthoff method. Household salt samples of the 540 selected children from schools were analyzed for its iodine content by standard iodometric titration method. Results The overall prevalence of Goitre was found to be 9.5 among children examined. The median urinary iodine excretion UIE was 104 mugL. All the household salt samples were adequately iodized having Iodine content of gt15ppm. Conclusion Considering prevalence of goitre in 6-12 years children Tumakuru district is lsquoendemicrsquo for IDD. But as inferred from median UIE obtained IDD is not a public health problem of significance. Household level salt is adequately iodized as per NIDDCP recommendations
