ABSTRACT
Objective To evaluate the control effect of the policy sustainable elimination of iodine deficiency disorders on the disease status after 15 years salt iodization, and to provide a scientific basis for the relevant policy adjustments. Methods Probability sampling method (PPS) was used to select 30 counties in Jiangsu province(except those iodine excess areas), of each county 40 children aged 8 - 10 were selected as the investigation objects, their thyroids were examined by palpation and B ultrasound, urinary iodine(UI), household salt iodine, and intelligence quotient(IQ) were also investigated. A questionnaire-based health education survey of children and women was also conducted. Results A total of 1200 salt samples were detected and the coverage and qualified rates of iodized salt were 97.5%(1170/1200) and 94.5%(1134/1200), respectively. Five hundred and ninety eight urinary samples of children aged 8 to 10 were detected. The median urinary iodine was 325.3 μg/L. Of 1200 children aged 8 to 10 examined, goiter was 1.70% (20/1200) by palpation and 1.00% (12/1200) by B ultrasound. Average IQ of those 598 children was 112.4 ± 13.2, and the proportion of mental retardation was 0.5% (3/598). The health education awareness were 95.9%(1830/1908) and 96.4%(431/447) for 636 students and 149 family women, respectively. Conclusions The control effect of iodine deficiency disorders is significant in Jiangsu province. Salt iodine concentration should be adapted to people's iodine nutritional status. Iodine nutrition needs of special population such as pregnant, lactation women and infants should be taking into account, and should also be combined with salt iodization status surveillance at county level.
