Iodine Deficiency Disorder and Goitre among School Children in Sarawak -A Nationwide Study.

Iodine deficiency disorders (IDD), is one of the most important micronutrient deficiencies which has multiple adverse effects on growth and development. The aim of this study was to determine the prevalence of IDD among school children and to elucidate the distribution of iodized salt at household...

The median urinary iodine concentration (UIC) among the school children was 102.1 μg/L (IQR, 62.3-146.5 μg/L). Urban children had significantly higher median UIC of 109.3 μg/L (IQR, 72.4-159.0 μg/L) than their rural counterparts [91.9 μg/L (IQR, 55.7-140.2 μg/L)].
