title: [Study of iodine intake in children from 6 months to three years-old in Guipúzcoa].
abstract: OBJECTIVE
  To assess whether iodine deficiency exists in healthy children aged 6 months to 3 years by measuring urinary iodine.
  
  
  METHODS
  A descriptive, cross-sectional study using purposeful sampling of children who attended 10 Primary Health Care centres in Guipúzcoa for routine health examinations.
  
  
  METHODS
  A total of 130 healthy children aged between 6 and 36 months, of whom 61 (46.9%) were girls and 69 (53.1%) boys.
  
  
  METHODS
  Age in months, origin, sex, nutritional survey (particularly intake of iodised salt, sea fish and dairy products) and urinary iodine excretion in a random urine sample.
  
  
  RESULTS
  The median urinary iodine was 127 μg/L. About one third (36.9%) of children had a urinary iodine below 100 μg/L. No relationship was found between urinary iodine and nutritional survey variables.
  
  
  CONCLUSIONS
  Iodine intake in the children studied is adequate according to WHO recommendations.
