Summary: | To evaluate the concentration of iodine in the
urine of infants (ioduria) and its possible relation to the
postpartum characteristics of the newborn infant, and to
assess the concentration of iodine in table salt, since this is
the food with the highest content of this micronutrient
ingested by the population, Methods: 32 infants under 6
months of age participated, The analysis of iodine in urine
was based on the Sandell-Kolthoff reaction (1937) and that
in salt on the titration method recommended by the National
Health Foundation (Funasa), Postpartum infant
characteristics were collected by means of a questionnaire
answered by the nursing mothers, A descriptive statistical
analysis was carried out, To compare the average ioduria of
the infants in terms of the variables: type of delivery,
breastfeeding, pregnancy and use of supplement, the
Student t-test was applied, Associations of interest were
examined by Fisher's exact test, The criterion of significance
was p0.05, Results: The mean height and weight of the
infants at birth were 47.5 cm and 3.2 kg, respectively, Most
infants received exclusive breastfeeding, took no
supplement, were born at term and by cesarean section, The
median urinary iodine found in the infants was 190.78 mg /L
and the average concentration of iodine in the salt was 75.59
mg I /kg salt, There was no correlation between the iodine
content in salt and ioduria in infants, Conclusion: The
median urinary iodine was found to be adequate, but the
concentration of iodine in salt was excessive, There were no
significant relationships between the postpartum
characteristics of the infant and urinary iodine.
