Dietary supplies of iodine and thiocyanate in the etiology of endemic goiter in Tripura.
In the post-salt iodization phase, a study on iodine nutriture status was conducted in Tripura of North East India. The clinical variable of the study was goiter and the biochemical variables were urinary iodine and thiocyanate. Random sampling methodology was followed for selecting the study areas in the State. In each study area, the studied population consisted of school children of both sexes in the age group 6-15 years. The total study areas were 22 and the total number of the population was 10,801. The total number of urine samples were analysed for iodine and thiocyanate were 1,032 (about 10%). The total goiter rate was 21.63%. Population of most of the studied areas had no biochemical iodine deficiency as evidenced by median urinary iodine excretion levels. However, the per capita consumption of iodine of about 40% population was inadequate. A large number of cyanogenic plants (SCN precursors) are used as common vegetables. This study ensures that the existing goiter prevalence in the region could possibly due to non-uniform adequate iodine supply along with the thiocyanate load.
