Caribbean Island Urinary Iodine Survey 2018

Many of the Caribbean island nations have no data on iodine status in their populations. Iodine deficiency in children can reduce IQ but can be easily corrected through a program of salt iodization. The study will be located at 11 islands of the Caribbean region. At each of the 11 study sites, we will measure the iodine status in school-age children by collecting morning spot urine samples for measurement of urinary iodine concentration (UIC). We will also measure height and weight in all children. We will collect a repeat, next-day spot urine sample in 1/3rd of children to adjust for intra-individual variation in spot UIC and calculate the distribution of population intake.
