Perkiraan Asupan Iodium Dan Natrium Menggunakan Urin 24 Jam Pada Anak Dan Dewasa

Basic health research (Riskesdas) 2007 found high rate of hypertension (31.7%). The question is, whether iodine fortification program in the salt still relevant because salt intake correlated with hypertension. This study is a cross sectional, assessing the levels of iodine and sodium in urine with estimation of iodine and sodium intake. This was a cross sectional study. Sample of this study were 99 families, including father, mother, and 6-12 years children. The study was conducted in three villages in Getasan Sub-district, Semarang District. Variables collected included body height and weight, iodine content of household salt, 24 hours urine volume, urine iodine and urine sodium excretion. Intake of iodine and sodium estimated with urinary iodine and sodium excretion values and urine volume. Type of salt consumed (97%) was brick form, the average of iodine content in salt was 20.4 ppm potassium iodate and consumption of salt was 8.0 ± 4.7 grams per day. Median and mean urine volume was 1500 (1523 mL ± 623) mL. The median urinary iodine excretion (EIU) is 93 (105 ± 61) μg/L. Proportion of subjects with < 100 μg/L UIE was 55.6% and ≥ 300 μg/L UIE was 1%. Median and mean urinary sodium excretion (USE) was 2588 mg/L (2732 ± 986) mg/L. The proportion of USE ≥ 2300 mg/L was 62%. Frequency of iodine and sodium food source consumption: 47.5% of subjects eating instant noodles and snacks 1-2 times a week, 98% consume MSG/ketchup/sauce ≥ 1 times a day. Frequency of salty foods consumption: 53.9% of subjects consumed 1-2 times a week and 26.9% consumed bread/biscuit/cake 1-2 times a week. Median and mean intake of iodine of subject (father, mother, child) was 113 ug/L and 126 ± 73 mg/L. Median and mean sodium intake were 3131 mg/L and 3306 ± 1193 mg/L. In sum, salt is a major source of iodine and sodium intakes although the level of iodine was considered low compared to the national standard of industry. The study location is a mild iodine deficiency area but considerably high intake of sodium based on the analysis of a 24 hour urine collection
