Prevalence of Endemic Goiter in School Children during Post Salt Iodization Period in Churachanpur District, Manipur, India
Journal Title: International Journal of Medical and Health Sciences - Year 2015, Vol 4, Issue 1
Abstract
Background: Manipur lies in the conventional goiter endemic belt of India because of its geographical location. Endemic goiter was found prevalent in valley districts of Manipur during post salt iodization period without biochemical iodine deficiency but certain goitrogens in plants grown in the region and consumed by the people have role in goiter formation. Therefore the present study has been undertaken to evaluate goiter prevalence in a hill district of Manipur. Objectives: The present investigation was aimed to study the goiter prevalence among school children (6-12 yrs) in Churachanpur district of Manipur, and to evaluate the goiter formation by assessing the urinary iodine and thiocyanate concentration, and iodine content in edible salt and drinking water. Methods: A total of 1416 school children were clinically examined for the enlargement of thyroid, 160 urine samples were analyzed for iodine and thiocyanate concentration. Iodine content was also measured in 140 edible salt samples and 20 drinking water samples. Results: Total goiter prevalence was found to be 28.39%, median urinary iodine level was 160.50 μg/l and the mean urinary thiocyanate concentration was 0.985 ± 0.046 mg/dl. All the salt samples had iodine above the recommended level of 15 ppm but the region was found environmentally relatively iodine deficient. Conclusions: The study showed that the region is clinically moderately goiter endemic without biochemical iodine deficiency. Consumption of certain plant foods containing cyanogenic glycosides might have played a role for the development of goiter during post salt iodization phase in this region.
