摘要
目的调查分析江门市新会区水碘含量对学龄儿童碘营养水平的影响,并根据调查结果提出学龄儿童碘营养有关的干预措施。方法研究类型为横断面调查研究,抽样方法为简单随机抽样法,以2022年1—10月在江门市新会区11个镇随机抽取的1所小学8~10岁学生440名(男女各半)为调查对象,采集调查对象尿液、食用盐及饮用水水样分别测定碘含量。结果440例8~10岁学龄儿童尿碘中位数为255.90μg/L,27.95%儿童尿碘处于正常水平,5.23%儿童尿碘偏低,66.82%儿童尿碘水平偏高;盐碘含量平均值为(24.99±5.26)μg/L,94.32%儿童盐碘为合格水平,3.18%儿童盐碘含量不足,2.50%儿童盐碘含量过量;水碘含量中位数为5.45μg/L,所有水样检测均为碘缺乏。相关性分析显示,8~10岁学龄儿童盐碘与尿碘无明显相关性(P>0.05);水碘与尿碘呈显著的正相关性(r=0.156,P=0.001);线性回归显示,盐碘含量与尿碘无明显关联,水碘含量每上升1μg/L,尿碘将增加6.700μg/L(P=0.001)。结论本组学龄儿童66.82%处于碘营养过剩水平,水碘含量和尿碘水平有正相关性,盐碘含量和尿碘水平无明显关联,低盐、低碘盐饮食或是改变学龄儿童碘营养过剩的实用策略。
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.
