Assessment of Urinary Iodine and Associated Factors in 8-10 Years Old Students in Zabol City

Iodine deficiency disorders (IDD) are the most important epidemic disorders in the world. Goiter is a major public health problem for population living with iodine deficient environments, particularly for young children. In the last two decades, the elimination of IDD has been considered as an integral part of many national nutrition strategies. The aim of current research was to determine urine iodine in elementary students and its relationship with their nutrients intake.

In a cross sectional study 240 students of both genders, aged from
8-10 years were selected from urban and rural area of Zabol city, through cluster random sampling methods. Urine of participants collected and then their urine iodine were determined by digestion methods. Information about nutrients intake gathering by 24 recall method and FFQ questionnaire. Data analyzed by SPSS 19.
P value < 0.05 was considered to be statistically significant.

Out of 240 participants registered in current research 41.7% of them were male and 58.3% were female. The median and mean iodine intake were 104µg and 108.13 ± 21.28 µg respectively. The median and mean of urinary iodine were 10.5 and 13.29 ± 6.95 µg/dl respectively. Mean daily intake of energy, carbohydrate and protein were 2292.58 Kcal, 150.42 and 48.59 gr respectively.

Data analysis showed a significant relationship between urinary iodine concentration and iodine intake (p value < 0.05). Statistical analysis also showed that there was no significant difference between urinary iodine in urban and rural areas (p value = 0.71) and their gender (p value = 0.43).
