ABSTRACT
Background:
Fifteen years after a nationwide voluntary iodine prophylaxis program was introduced, the aims of the present study were (a) to obtain an up-to-date assessment of dietary iodine intake in the Veneto region, Italy; and (b) to assess dietary and socioeconomic factors that might influence iodine status.Methods:
Urinary iodine concentration (UIC) was obtained in 747 school students (median age 13 years; range 11-16 years).Results:
The median UIC was 111 µg/L, with 56% of samples ≥ 100 µg/L, but 26% were < 50 µg/L, more frequently females. Iodized salt was used by 82% of the students. The median UIC was higher among users of iodized salt than among non-users, 117.0 ug/L versus 90 ug/L (p = 0.01). The median UIC was higher in regular consumers of cow's milk than in occasional consumers, 132.0 µg/L versus 96.0 µg/L (p < 0.01). A regular intake of milk and/or the use of iodized salt sufficed to reach an adequate median UIC, although satisfying only with the combined use. A trend towards higher UIC values emerged in regular consumers of cheese and yogurt.Conclusion:
Iodine status has improved (median UIC 111.0 µg/L), but it is still not adequate as 26% had a UIC < 50 µg/L in the resident population of the Veneto region. A more widespread use of iodized salt but also milk and milk product consumption may have been one of the key factors in achieving this partial improvement.Palavras-chave
