Abstract
The aim of the present study is to evaluate the relationships between urinary iodine concentration (UIC) and the intake of milk and other foods, in a group of school children of the Veneto region, in North East Italy. A questionnaire, concerning the daily intake of milk, yoghurt, cheese and other animal foodstuffs, was distributed to 233 schoolchildren aged between 11 and 15 yr. The use of iodized salt was also investigated. UIC was measured in a casual urine sample of all children investigated. The iodine content of 28 samples of milk and of 13 samples of yoghurt, bought during the summer in shops of the same area, was measured. UIC values ranged between 25 and 436 μg/l, median value was 140 μg/l, mean value 149±78 μg/l. The median iodine content of milk and yoghurt were 278 μg/l and 216 μg/l, respectively. With regard to dietary habits, about 70% of the children took 200 ml of milk or more per day, which corresponds to a daily intake of iodine ranging between 50 and 100 μg a day. About 30% of schoolchildren used iodized salt. A highly significant correlation between UIC and milk intake was observed (p=0.0005), while the relationship was poor or absent in the case of both intake of other foodstuffs and use of iodized salt (p=0.38). In conclusion, the results of the study document the very important role of cows’ milk as a source of iodine in childhood in the Veneto region, Italy.Keywords
