To understand the current situation of iodine deficiency disorders of Xinjiang Production and Construction Corps, in order to provide evidence for establishing prevention and control strategies.

According to their sub-area positions of east, west, south, north and center, 5 units were extracted in each division via the random sampling method, 4 companies were sampled in each chosen unit, 15 households were selected in each chosen company to detect salt iodine content in 2015; and 1 elementary school was sampled in each chosen unit, 40 students aged 8-10 were selected to collect their urine samples in each school to test urinary iodine and determine the goiter. Twenty pregnant women were randomly selected in each unit to test urinary iodine. Salt iodine was tested using direct titration, urinary iodine was determined using arsenic osmium catalytic spectrophotometry, thyroid was examinated using B-ultrasound.

Totally 3 915 edible salt samples were monitored. The mean of salt iodine was (27.8 ± 5.5) mg/kg, with 99.1% (3 880/3 915) iodized salt coverage rate, 93.2% (3 617/3 880) iodized salt qualified rate and 92.4% (3 617/3 915) qualified iodized salt consumption rate. The goiter rate was 1.0% (26/2 552) and the median of urinary iodine was 217.9 μg/L of 2 552 children aged 8-10, urinary iodine of southern region and northern region was 212.1 and 222.1 μg/L, respectively. The median of urinary iodine of 1 233 pregnant women was 157.7 μg/L.

The iodine nutrition level of key groups have already reached the national standard for eliminating iodine deficiency disorders, we should pay more attention to lower level urinary iodine of pregnant women.
