Abstract:"Introduction: Apart from iodine content of the salt consumed, the prevalence of IDDs are influenced by factors like storage of salt, environmental factors, overall nutritional status and socio-economic status. Objectives: The objectives f the study were to es-timate the prevalence of iodine deficiency in coastal and hilly vil-lages of south Odisha; and to analyse the predictors for poor io-dine nutrition status in the community. Methodology: This was a cross sectional study in south Odisha. UIE and household salt iodine content was estimated and logistic regression model was applied to determine predictors of poor iodine nutrition. Results: The median UIE in coastal district was found to be 126.4 mcg/L, whereas it was 73.0 mcg/L in the hilly areas. The household salt iodine level of more than 15 ppm was found in only 62% households. Nearly 50% households did not store their salt in airtight containers. The results of logistic regression revealed that hilly region (OR=10.2), household salt iodine content (OR=2.3), storage of salt in non air tight containers (OR=3.7) and stunting (9.8) were the main determinants of poor iodine nutrition. Conclusion: Poor iodine nutrition was significantly associated with region, household salt iodine content, salt storage in non airtight containers and malnutrition.
