Assessment the Control of Iodine Deficiency Disease in Qianjiang District in 2009

Objective To evaluate the prevention and implementation on the control of iodine deficiency disorders（IDD）,and to provide a scientific basis for the IDD objective assessment in Qianjiang district.Methods Five towns,covering the East,South,West,North and Intermediate region,were randomly selected in the whole region.Salts from 200 residents were randomly sampled and tested for iodine content.40 male and 40 female children,aged 8-10 years,were randomly selected from 5 primary schools and examined for thyroid palpation.Urine samples from 100 children,aged 8-10 years,were analyzed for the urinary iodine.150 students were investigated for their awareness of the health education situation.The study also included the iodized salt selling network,the number of sale outlets and iodized salt distribution,iodized salt supply and sales in these five towns.Results 95.5% of salts were qualified.The median urinary iodine content from the children was 245.9 μg/L,in which 66% samples had a range of 50~200 μg/L,30% had a concentration of 300 μg/L,and 3% of samples had a concentration of 50 μg/L.4.25% of children had hyperthyroidism.85.33% of Grade 5 students had the awareness of iodine deficiency disease prevention,and the average score was 4.46 out of 5.Conclusion The technical indicators of IDD have reached the standard in Qianjiang district.
