Abstract：Objective To investigate the status of iodine nutrition after adjustment of salt iodine content among population in Zhuhai City, and to provide a basis for timely adopting targeted prevention measures and scientifically adjusting intervention strategies. Methods Households consumed iodized salt and children aged 8-10 years in 2011 and 2015 were selected as the research subjects. Households’ salt samples and children’s urine samples were collected, and then the iodine contents in salt and urine samples were detected. Results A total of 1,730 salt samples were tested in 2011 and 2015, and the consumption rates of qualified iodized salt were both more than 97%. The median of salt iodine in 2015 was lower than that in 2011 (23.30 mg/kg vs. 30.49 mg/kg), with a statistically significant difference (Z=-31.224, P=0.000). A total of 900 urinary iodine samples collected from the children were detected in 2011 and 2015. The median of urinary iodine in the children in 2015 was lower than that in 2011 (133.95 μg/L vs. 216.85 μg/L), showing a statistically significant difference (Z=-9.351, P<0.05). The medians of urinary iodine in children in Xiangzhou District (Z=-10.177) and Jinwan District (Z=-7.204) in 2015 were both lower than those in 2011, while the median of urinary iodine in children in Doumen District (Z=-2.826) in 2015 was higher than that in 2011 (P<0.05). Conclusions The control work on salt iodization had made significant effect in Zhuhai City after the implementation of the national new standard for edible salt iodine content. Iodine content of salt among households and urinary iodine level among children aged 8-10 years in Zhuhai City were both declined. The overall iodine nutrition status among population in Zhuhai City was good, but the differences existed in different districts. It is still necessary to continuously conduct health education and monitoring on knowledge related to iodine deficiency disease prevention and treatment.
