[Iodine nutritional status and intake levels in adult from different water iodine content areas of Xinjiang Uygur Autonomous Region in 2017].

OBJECTIVE

To understand the iodine nutrition status of adults in Xinjiang Uygur Autonomous Region under the effective control of iodine deficiency disease.

METHODS

Using stratified cluster random sampling method, in the district to determine water iodine median<10 μg/L and ≥10 μg/L of urban and rural areas, a total of 10 survey points, deals from the collecting water deals of extracting water iodine content detection. Adults over 18 years old were randomly selected from 30 households at each survey site to carry out a survey on dietary iodine intake, and the contents of dietary salt iodine and adult urine iodine were tested.

RESULTS

The median iodine content in water in Xinjiang Uygur Autonomous Region was 4. 4(2. 3, 13. 6)μg/L. The median iodine content of household salt was 27(24, 30) mg/kg. The median urinary iodine content in adults was 168(103, 259)μg/L. The average dietary iodine intake of adults in the region was 312 μg/d.

CONCLUSION

The water iodine content in the environment outside Xinjiang Uygur Autonomous Region is relatively low, and the iodine nutritional status and dietary iodine intake of adults are generally at the appropriate level. However, urban adults with relatively low water iodine content and good economic status have a higher risk of iodine deficiency. Iodized salt is the main source of dietary iodine for adults in Xinjiang Uygur Autonomous Region. Adults in poorer rural and urban areas rely more heavily on iodized salt.
