---

ABSTRACT
Iodine deficiency or excess lead to the impairment of hormone production and thyroid function, and in the long term can cause health problems. Epidemiological criteria to determine the severity of Iodine Deficiency Disorders (IDD) in an area can be done by assessing the iodine status of school-age children. Indicator that can be used includes urinary iodine concentration (UIC). Indication of excess iodine in school-age children in some parts of Indonesia has been reported, among others, in Demak and Blora Regency, while on the other hand, the number of households consume enough iodized salt are low. Exploring the iodine status of school-age children aged 6-12 years in areas with high UIC values in non endemic iodine deficiency areas. The study was conducted in Blora and Demak Regency, Central Java. Samples were 300 school children aged 6-12 years.

Variables: Iodine status (thyrotropin hormone, urinary iodine concentration and thyroid gland enlargement). Other variables: nutritional status, nutrient intake, iodine in drinking water, iodine intake sources, iodine in salt. The median value of urinary iodine in Demak regency —were 4266 pg/L in Pidodo Village and 6216 pg/L in Sampang Village. In Blora Regency was 333 pg/L - Japah Village with 54.7% of subjects were at risk of iodine excesses. Hypothyroid subjects were found 24%, 16% and 10% in Sampang, Pidodo and Japah Village respectivelly.

The Proportion of non-visible goiter in Demak Regency was more than 30% where in Japah Village was only 5.5%. The high urinary iodine concentration in Blora Regency was suspected as the results of iodized salt intake. However the high urinary iodine in Demak Regency (Pidodo and Sampang Village) was not caused by iodine high intake, but probably from another cause that needs to be further studied.

Keywords: Iodine status; school-age children; excessive iodine intake.
