Perbandingan kandungan iodium dalam urin antara sampel urin 24 jam dan on spot pada anak usia sekolah
Abstract: Urine Iodine
Concentration (UIC) is the indicator to assess iodine status. UIC from 24-hour
urine collection appropriate to used as a direct measure of the iodine status
and helps to validate the estimates intake of iodine. 24-hours urine collection
is not practical in large studies and epidemiological surveys because it is
quite difficult to complete and accurate collection. WHO/UNICEF/ICCIDD
recommend the use of on spot urine collection.
Objective: The aim of this study was to compare of 24-hour urine
collection and spot urine collection for the assessment UIC in children.
Method: The cross-sectional study was applied in Bogor. UIC was measured
in 24-hour urine and parallel collected three spot urine namely on spot 1
collected morning, on spot 2 collected afternoon, and on spot 3 collected
evening, sample urine collected from 44 healthy children age 10-13 years. UIC
of 24-hour urine and one spot urine analyzed in the laboratory GAKY FK UNDIP
using acid digestion method.
Results: The average UIC from 24-hour urine collection was 179.77 ± 56.4
µg/l and UIC from on spot urine collection were on spot morning 145.30 ± 63.6
µg/l, on spot afternoon 159.95 ± 64.5 µg/l, and on spot evening 167.50 ± 66.1
µg/l. However, UIC correlation between UIC from on spot afternoon and UIC
24-hour (r = 0.456) with 66.67 % sensitivity and 75.61 % specificity.
Conclusion: UIC urine samples from lunch to dinner more accurately
reflects the UIC 24 hours to categorize the iodine status of the population.
UIC from spot urine samples collected on the afternoon can be used as an
alternative to evaluate the iodine status of school-age children.
