Asupan yodium dan asupan goitrogenik hubungannya dengan status gangguan akibat kekurangan yodium (GAKY) pada anak sekolah dasar di kabupaten Dairi Provinsi Sumatra Utara

Background: Iodine deficiency disorder (/00) is a health problem which affects the quality of human resources. 100 is caused by lack of iodine substance. The substance is needed for numerous syntheses and metabolism in the body, particularly thyroid glands. 100 may also be caused by high consumption goitrogenic substance. ObjectIve: The study was meant to identify relationship between iodine and thiocyanate intake and 100, and to identify differences in iodine and thiocyanate intake based on endemic level. Method: This was an observational study with cross sectional design. Method used were palpation of goiter glands to measure endemic level, food recall, and food frequency questionnaire (FFQ) to measure iodine and thiocyanate intake, ammonium persulfate digestion to measure urine iodine excretion. Data analysis used chi-square, Pearson correlation and anova. Results: The result of chi-square analysis showed that there was no significant relationship between iodine intake and /DO (p > 0.05, CI 95%: 0,34-1,18), but there was significant relationship between iodine intake and urine iodine excretion (p 0.05, C/95%: 0.48-1.97). The result of Pearson correlation test showed that there was no significant relationship between iodine and thiocyanate FFQ and 100 (p > 0.05)there was no significant relationship (but there was a tendency) between thiocyanate FFQ and /DO (p > 0.05). There were significant differences in iodine intake, thiocyanate intake, iodine FFQ and thiocyanate FFQ based on endemic level (p > 0.05). ConclusIon: There was relationship between iodine intake and 100/non-100, but there was relationship between urine iodine excretion and 100. Children with 100 had higher consumption of thiocyanate than those who did not have 100. There were differences in all measurements based on endemic level.
