Summary
The purpose of this study is to determine whether universal salt iodization (USI) meets the
iodine requirements of pregnant women, lactating women and infants.
Clinical Details
Official title: Salt Iodization and the 1st 1000 Days: Does a USI Program Cover the Iodine Requirement of Pregnant and Lactating Women and Infants?
Study design: Time Perspective: Cross-Sectional
Primary outcome: Urinary iodine concentration (µg/L)
Secondary outcome: Thyroglobulin (µg/L)Breast milk iodine concentration (µg/L)
Detailed description:
Because pregnant women, lactating women and infants are the groups most vulnerable to iodine
deficiency and its irreversible consequences, programs should focus on these groups. But
like other mass fortification strategies, it is uncertain whether USI can meet the increased
dietary requirements of pregnant women, lactating women and infants. Objective of this study
to test whether USI can meet the dietary requirements of iodine in women of reproductive
age, pregnant women, lactating women and infants up to 2 years of age without causing excess
iodine intake in school children and non-pregnant non-lactating women. The study hypothesis
is that USI, when fortified at adequate levels and applied to all salt consumed, including
both household salt and salt used for processed foods, provides adequate dietary iodine for
all population groups, except for weaning infants; while not posing any risk of excessive
iodine intakes in other age groups.
