Iodine deficiency is related to a spectrum of diseases collectively referred to as iodine deficiency disorders. It is a risk factor for the growth and development of up to 2.2 billion people living in iodine deficient environment in 130 countries of the world. This cross sectional study aimed at determining the household salt iodization level and the urinary iodine concentration and prevalence of iodine deficiency in 400 randomly selected pupils (6 - 12 years) attending public primary schools in Zaria, North-western. Approximately 15 g salt (three teaspoons) was collected from each of the 400 students. Casual urine samples were obtained from a sub sample of the students (n -100) using sterile containers in the morning hours. Standard methods were used to determine the concentration of iodine in the salt and urine samples. Results show that all the salt samples contained iodine, 96% were iodized within the recommended level (≥ 15 mg/kg), and only 4% had iodine content that were below the recommendation. Urinary iodine concentration revealed that 78% of the respondents were deficient in Iodine. None was severely deficient while 63%, 15% were mildly and moderately deficient respectively. Also, 1% were at risk of Iodine induced hyperthyroidism, while only 21% had adequate Iodine concentration. The mean and median urinary iodine concentration were 82.08 ± 35.71 μg/L and 72.31 μg/L respectively. The respondents in this study had access to iodised table salt. However, more than half of the population were moderately and mildly iodine deficient.
