title: Assay of iodine deficiency status in three ecological regions of Nepal by a microdigestion method.
abstract: Iodine deficiency disorders (IDD) are a global public health problem. In continuation of the efforts to eliminate the iodine deficiency in different parts of the world, IDD surveys are being conducted to assess the status of iodine nutriture. A survey was conducted in Nepal in 1998 with assistance from UNICEF. We present the status of the iodine nutriture, as assessed from urinary iodine levels of casual samples by a micro-digestion method, in the three ecological regions: Terai (flat region), Hilly region (300-3,000 m altitude) and mountainous regions (>3,000 m altitude) of Nepal. Terai region is more affected, having iodine deficiency in 18.6% of the population. The hilly and mountainous regions were found to have 11.2% and 9% iodine deficient populations respectively. The study shows improvement in iodine deficiency status with respect to previous surveys yet it continued to be prevalent in the country as a major public health problem which requires strengthening of preventive measures.
