Konsumsi Zat Yodium dan Zat Goitrogenik sebagai Faktor Resiko Gaky pada Anak Sekolah Dasar di Kecamatan Tabir Ulu, Kabupaten Maringin, Provinsi Jambi: Iodine and Goitrogenic Intake as Risk Factors for Iodine Deficiency D

In spite of extensive iodine supplementation, Iodine Deficiency Disorders (IDD) is still a public nutritional problem in Indonesia. Beside related to iodine deficiency, IDD can also due to excessive goitrogenic intake. This research was aimed to assess the contribution of iodine deficiency and goitrogenic excess in causing goiter in elementary school children of Tabir Ulu Sub-District. This was a case control study using children with goiter as cases and those without goiter as controls. Iodine and goitrogenic intake were assessed by food frequency questionnaires. Data on urinary iodine and thiocyanate were also collected. The results showed that after controlling for each other, both low iodine intake, OR (95%CI) of 3.1(1.2-7.7), and excess thiocyanate intake, OR (95%CI) of 2.9(1.2-6.7), were related to goiter. Low protein intake was also significantly related to goiter, OR (95%CI) of 4.5(1.9-10.7). In children with low iodine intake, urinary iodine was inversely associated to urinary thiocyanate (r =-0.34, p=0.04). It was concluded that goiter in these children is related to low iodine intake, high goitrogenic intake and low protein intake. Key words: goiter �school children �iodine �goitrogenic � thiocyanat
