Study on Effect of Water Iodine Content for Iodine Nutrition Level of School Age Children and Intervention Measures
Objective To investigate and analyze effect of water iodine content on iodine nutrition level of school-age children in Xinhui District,Jiangmen City,and propose intervention measures related to iodine nutrition of school-age children based on the survey results.Methods Research type was cross-sectional survey,and sampling method was simple random sampling.The paper chose 440 aged 8-10 students(half male and half female)in a primary school of 11 towns in Xinhui District,Jiangmen City from January to October 2022 as survey subjects,collected urine,edible salt,and drinking water samples of survey subjects to measure iodine content.Results Median urinary iodine of 440 cases school-age children aged 8-10 was 255.90μg/L,27.95%of urine iodine was at a normal level,5.23%was low,and 66.82%was high.Average salt iodine content was(24.99±5.26)μg/L,94.32%was at qualified level,3.18%had insufficient iodine content,and 2.50%had excessive iodine content.Median water iodine content was 5.45μg/L,all water samples test showed iodine deficiency.Correlation analysis showed there was no significant correlation between salt iodine and urine iodine of school aged children aged 8-10,(P>0.05).There was significant positive correlation between water iodine and urine iodine,r=0.156,P=0.001.Linear regression showed there was no significant correlation between salt iodine content and urine iodine,water iodine content every increased 1μg/L,and urine iodine could increase by 6.700μg/L(P=0.001).Conclusion 66.82%of school-age children in the group have an iodine excess level,there is positive correlation between water iodine content and urine iodine level,and there is no significant correlation between salt iodine content and urine iodine level.A low salt and iodine salt diet may be practical strategy to change iodine excess of school-age children.
