ABSTRACT
Background: Iodine deficiency is a public health problem in many developing countries where pregnant women and
children are the more susceptible populations.
Objective: To evaluate the association of iodine nutritional status with
the weather, availability of iodine in salt, and degree of social exclusion in preschool children of the state of Hidalgo,
Mexico.
Methods: Cross-sectional study in 1,333 children ‹ 5 years; in these, urinary iodine and iodine in the salt was
measured, and annual average of humidity, type of location and degree of social marginalization in the localities where
they lived was recorded.
Results: 24.5% of children evaluated had ‹ 100 µg/l of urinary iodine excretion, and 28.6% of
salt samples contained ‹ 20 ppm of iodine; iodine urine average of wet weather children was lower (209.09 ± 6.8 µg/l)
than in dry climates (274.7 ± 5.86 µg/l; p ‹ 0.05); the iodine content of salt in children living communities with high
levels of marginalization was less than with low marginalization (23.5 ± 1.2 and 32.9 ± 2.7 ppm, respectively; p ‹ 0.01).
Conclusions: The humidity and the degree of social marginalization of the locations were associated with lower iodine
content of salt and urinary iodine in children evaluated.
