Abstrakt:	Objectives: To determine the current prevalence of simple goitre in the school population of a health district where goitre is traditionally endemic. Calculation of the deficiency or otherwise of iodine through the determination of mean urinary excretion of iodine in the population under study. Design: Cross-sectional descriptive study. Setting: Olvera Health District (Cádiz). Participants: School students in the health district between 6 and 14 years old out of a total of 1969. Sample size of 92 school students was chosen at random, for a 95% confidence interval. Measurements and Main Results: Dependent variables were the existence of goitre found in a physical examination, urinary excretion of iodine measured in microg/dl in the first urine of the morning, origin of water consumed and habitual consumption of iodised salt in their diet. 87% of the population under study habitually drank water from the normal supply, 4% from wells or springs, and 9% mineral water. 57% of parents did not know whether the salt in their normal diet was iodised or not. 29.3% of school students included in the study had some degree of goitre. The mean excretion of iodine in urine was 13.78 microg/dl (95% CI, 12.30-15.26). Ioduria was below 9.9 microg/dl in 28.2%, within the endemic figures. Conclusions: The mean amount of iodine in urinary excretion in the sample means that the risk of developing goitre is low, although the prevalence of goitre continues at endemic figures.
