The Goodness of Salt Quick Test as Compared to Titration Method for Mass Screening of the Iodine Level in the Community
Diagnostic study on Quick salt test and titration methods toward Urine Intake Excretion (UIE) level in Indonesia had been conducted after the baseline data of Iodine salt available (Riskesdas 2007). For the baseline, samples were selected purposively covering households of 30 districts/municipalities based on the previous Iodine Salt Survey (SGY 2993). The dependent variable was Iodine level of UIE, and the independent variables were salt quick test and titration Analysis were by- 1) linier regression to determine correlation between the salt titration and UIE; 2) Analysis of vanance was to comparemean difference between of UIE and quick salt test as well as titration; and 3) Chi-square test was to determine risk factors of two examined variables. Results showed that there was correlation between titration and UIE level by the power of 7.3% and can be explained by 0. 5%. Significance Chi-Square test showed. there was significance difference of UIE level according to quick salt test (p=0.000; OR 1. 762). Similarly to titration, there was significance difference of UIE level according to titrat 1onp=0.001; OR=1. 740). ANOVA test showed that there was significance difference of UIE accordmg to titration (p=0.019), although the means difference was not so wide (means of enough iodine was 274.73 meg and less of iodine was 248 38 meg) respectively. In conclusion, the implementation of both salt quick test and titration result was Significance toward the UIE level. The quick salt test was more sensitive compare to titration, but, the later was more specific. Nevertheless, the salt quick test is more benefited as it is cheaper. handy, and simple to conduct. It was recommended that salt quick test to be used to determine the iodine level for massive screening to predict the UIE level because it has correlation, sensitivity, simple, easy to be implemented and applicable in future.
