Climat Impact on Urinary Iodine Concentration

NCT03215680 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 363

No results posted yet for this study

Summary

Urinary iodine concentration (UIC) is the recommended biomarker of iodine status in populations. Yet, the influence of climate on UIC remains unclear. Hot climate may reduce urine volume and consequently increase UIC independent of iodine status. This could lead to an overestimation of population iodine intake, thus masking iodine deficiency in vulnerable groups.

In this longitudinal observational cohort study in women of reproductive age we will collect 24h and spot urine samples in the summer and winter season. The influence of high temperature climates on UIC, measured and estimated urinary iodine excretion will be estimated.
