Abstract

Abstract

Objective To understand the iodine nutritional status and source distribution of residents aged 18 and above in non-water-borne high iodine areas in Tianjin, and compare the methodological difference between the 3 d dietary survey method and the 24 h urine iodine method when calculate total dietary iodine. Methods According to the Chinese adult chronic disease and nutrition surveillance program, a total of 1 634 inhabitants aged 18 and above were enrolled from Hexi, Nankai, Hongqiao, Wuqing, Jinnan, Baodi and Jizhou district of Tianjin. The total dietary iodine intake was obtained with 3 d dietary recall and condiment weighing method, And the iodine nutritional status of adult residents in Tianjin and iodine contribution rate of each part were described.403 investigators were randomly selected from the 1 634 inhabitants mentioned above for 24 h urine iodine concentration detection, and the difference between 3 d dietary survey method and urine iodine conversion method when calculate total dietary iodine were compared. Results The median dietary iodine intake of adult residents in non-water-borne high iodine areas of Tianjin was 207.13 μg/standard person day, 70.3%respondents were in iodine adequate state. It was found that salt iodine is the main source of total dietary iodine (78.2%), followed by food iodine (13.2%) and water iodine (8.6%). Overall, the dietary iodine intake estimated by 3 d dietary survey method was higher about 10% compared with the result estimated by 24 h urine iodine concentration. Conclusions The adults in the non-water-borne high iodine areas in Tianjin was generally in iodine adequate state. Salt iodine is still the main source of dietary iodine, and little difference is found about the total dietary iodine intake estimated by 3 d dietary survey and 24 h urine iodine conversion method.
