Abstract: Objective To understand the iodine nutrition levels among school-age children in non-iodized areas after adjustment for iodine concentration in edible salt by monitoring the consumption of iodized salt and the urinary iodine level among 8-10year-old children. Methods In accordance with the method of cluster sampling,salt samples were collected 2700 households,180villages and 45 townships in non-iodized areas to conduct quantitative detection on edible salt iodine content.Urine samples of children were collected with the Probability Proportionate to Size Sampling(PPS)to analyze the result of urinary iodine. Results A total of 2 700 samples of household salt were monitored,the iodized salt coverage rate was 98.74%,The qualified rate of iodized salt was 96.88%.the rate of qualified iodized salt consumption was95.67%.The urinary iodine median of 8-10year-old children was 187.90ug/L,the values of urinary iodine were positive skewness distribution.The urinary iodine median of schoolboys was 198.80ug/L.but the urinary iodine median of schoolgirls was 181.80 ug/L,with statistical differences in gender(P <0.01).The urinary iodine median of pupils was182.60ug/L in urban areas,and 198.70ug/L in rural areas,(P <0.01). Conclusion The overall iodine nutritional level is suitable after adjustment for iodine concentration in iodized salt among 8-10year-old school-age children in Jinan city,but with differences in gender and areas.
