Troubled by decades of civil war, Afghanistan was unable to introduce IDD preventive measures until 2003. After a decade of progress, women and children are now iodine sufficient. Afghanistan is a country with a historical high prevalence of iodine deficiency disorders (IDD) throughout the country. The 2004 National Nutrition Survey (NNS) showed that women and children were moderately iodine deficient. The median urinary iodine concentration (MUIC) was 49 mcg/L in children, 42 mcg/L in young women, and 37.5 mcg/L among pregnant women.
