IODINE NUTRITION IN THE REPUBLIC OF ARTSAKH (NAGORNO KARABAKH)

Objective: Iodine is a required nutrient for thyroid function. The mountainous terrain in the Republic of Artsakh (Nagorno Karabakh) in the south Caucasus suggests that it is likely to be endogenously deficient in iodine. The region is heavily dependent on neighboring Armenia for food imports including iodized salt. Since 2005, iodine is a government-sanctioned compulsory supplemental ingredient in salt in Armenia. However, there has never been a study of iodine nutrition in Artsakh. We sought to determine the level of iodine nutrition in Artsakh and the iodine content of table salt in the region. Methods: Using a cross-sectional modified cluster model, we measured urine and salt iodine concentrations from a representative sample of children living in Artsakh. From 30 schools throughout the territory, we obtained 772 urine samples from children aged 8 to 10, and 323 samples of table salt. Repeat urine samples from 18.6% of participants were obtained. Results: The median adjusted urinary iodine content was...
