Hubungan Antara kadar yodium urin dan memori jangka pendek pada anak sekolah dasar di daerah epidemis gaky

Abstract

Background: Good short term memory ability is essential in order to improve children’s academic achievement. Decrease in short term memory function can be found in children on Iodine Deficiency Disorders (IDD) endemic area. Urinary Iodine (UI) concentrations is the recommended method to determine status of IDD endemic area. Aim: To determine the correlation of urinary iodine concentrations and short term memory in elementary school children in IDD endemic area. Methods: This was an analytic observational study with cross sectional design. Samples were 50 elementary school children aged 9-11 years old who lived in IDD endemic area in Sub Kertek, Wonosobo Regency, Central Java Province. Short term memory function was evaluated by Digit Span test. Spot urine samples were retrieved to assess UI concentrations. Spearman test were used for statistical analysis. Results: Median ± deviation standard digit span forward score 4.00 ± 0.89, digit span backward score 2.00 ± 0.35, digit span scaled score 5.00 ± 1.64, and UI concentrations 287.00 ± 64.49 μg/L. There were significant correlation between UI concentrations with digit span forward score (p=0.009) and digit span scaled score (p=0.009) but not significant with digit span backward score (p=0.136) Conclusion: There were positive correlation between UI concentrations and short term memory in elementary school children on IDD endemic area. Key Words: IDD, urinary iodine concentrations, short term memory, elementary school children.
