Monitoring iodine intake in children aged 2-10 years
Jodkids: a Study of Iodine Intake Among Children Aged 2-10 Years
This study is testing how well children aged 2-10 in Denmark are getting enough iodine from their diet since the country increased iodine levels in food, to make sure it's safe and healthy for their growth and development.

What this trial studies
This observational study aims to assess the effects of increased iodine fortification levels implemented in Denmark in 2019 on the dietary iodine intake and urinary iodine excretion among children aged 2-10 years. It consists of two sub-studies: one estimating iodine intake and food sources, and the other validating dietary records against actual iodine intake measured in urine. The study will involve 600 participants to identify potential risks of excessive iodine intake and ensure adequate iodine levels for optimal thyroid health and neural development in children.
Who should consider this trial
Good fit: Ideal candidates for this study are children aged 2-10 years living in Denmark.
Not a fit: Patients with chronic diseases affecting iodine metabolism or those whose parents cannot complete the required questionnaires may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could help optimize iodine fortification levels to ensure children receive adequate iodine for healthy development.
How similar studies have performed: Other studies have shown the importance of monitoring iodine intake in children, but this specific approach to assess the impact of fortification levels is relatively novel.
