Research of Iodine Nutrition Levels in Akto County, Xinjiang, China from 2009 to 2014

Objective: To understand the effect of prevention and control of iodine deficiency disorders with iodized salt in Akto County, Xinjiang, China, to provide a scientific basis for formulating effective method of prevention. Methods: Sampling survey was conducted in Akto County in 2004, according to National Key Survey Scheme in High-risk Areas. Results: The median of the iodized salt was 32.8 mg/kg in 2004, with intake rate of qualified iodized salt of 100% in the residents. Goiter rate of the children was 22.0% by palpation, and 10.0% by B-ultrasound, with the coincidence rate of 66.8%. Compared with those in 2014, there were statistical differences (P<0.05) in children's goiter rate by palpation (χ2=86.10) and B-ultrasound (χ2=28.03) in 2009. While statistical difference in urine iodine levels of children was also found between 2009 and 2014 (t=5.58, P<0.005). Conclusion: Universal coverage of iodized salt is an effective way to control IDD.
