Background:With Universal Salt Iodization, district-wise monitoring of Iodine deficiency disorders (IDDs) along with potential toxic effects of excess Iodine intake is essential. This study was conducted with the objective of estimating the prevalence of IDD and prevalence of house-hold consuming adequate iodine in salt at consumer level, in Damoh district, Madhya Pradesh in 2016.Methods:The cross-sectional study with cluster sampling was conducted, among school-going children (6-12 years of age). Overall, 30 schools (clusters) and 90 children from each cluster (30*90=2700) were selected to access Total Goiter rate (TGR). Total 540 salt samples and 270 urine samples were collected to estimate salt iodine content from their house-hold and Urine Iodine Excretion (UIE) respectively. Also, 150 households and 30 shopkeepers were interviewed to understand the awareness level for salt iodization.Result:The TGR in Damoh was 2.08% with prevalence of Grade I&II as 1.67% and 0.41% respectively. The 26% of population had iodine deficiency, 28% had adequate iodine levels, while 46% population had either more than adequate or toxic level of Iodine. Besides, 72.4% of the population consume adequately iodized salt.Conclusion:Damoh is no more endemic for IDD. However, we recommend monitoring is required to assess IDD as well Iodine-induced hyperthyroidism in future.
