摘　　要：目的探讨苏北某地区8-10岁儿童碘营养状况及影响因素,为学龄儿童科学补碘提供依据。方法依据水碘监测分层整群抽取苏北某地区低、中及高碘地区8-10岁学龄儿童724名,进行水碘、家庭食用盐碘、儿童尿碘检测,部分儿童家长进行问卷调查。结果低、中、高碘地区水碘中位数分别为8.89,38.52,189.25μg/L,儿童的尿碘中位数分别为135.49,183.62,448.99μg/L,差异均有统计学意义（P值均〈0.01）。在非高碘地区,水碘含量低是儿童缺碘的危险因素（OR=2.695）,碘与健康相关知识知晓率高,方便面、鸡蛋、牛奶食用频率高是保护因素（OR值分别为0.611,0.569,0.713,0.547,P值均〈0.05）;男性、超重、肥胖、缺乏碘与健康相关知识、豆制品食用频率高是碘过量的危险因素（OR值分别为2.338,5.032,1.090,0.538,1.414,P值均〈0.05）。高碘地区,除水碘含量外,动物肝肾进食频率高是危险因素（OR=3.052,P〈0.05）。结论苏北某地区学龄儿童尿碘水平基本达到国家消除碘缺乏病的标准,但尿碘水平偏低和偏高的儿童仍占有一定的比例。应采取针对碘与健康相关知识、食盐管理、营养综合干预措施使儿童碘营养保持在适宜的水平。Objective To explore the iodine nutrition and effect factors of children aged 8-10 years old in northern Jiangsu for providing a scientific basis of prevention iodine deficiency disorders（ IDD）. Methods According to local water iodine monitoring data, a stratified cluster sample was conducted to preschool children aged 8-10 in low, medium and high water iodine area to detect the water iodine, family edible salt iodine content and children＇ s urine iodine, the questionnaire for some children and their parents is also included. Results The median water iodine in low, medium and high water iodine area were respectively 8. 89,38.52,189.25 μg / L.The median urinary iodine of school-age children in low, medium and high water iodine area were respectively 135.49,183.62,448.99 μg / L. Each of them has significant difference. In non-high iodine area, risk factors of IDD was low water iodine（ OR = 2.695）.Good awareness rate of knowledge of iodine and health, the high consumption of instant noodles, egg and milk were the protective factors（ OR = 0.611,0.569,0.713,0.547,P〈0.05）; risk factors of excessive urinary iodine were male, overweight and obesity, deficiency knowledge and high consumption of dried bean curd（ OR = 2.338,5.032,1.090,0.538,1.414,P〈0.05）. In addition, in high iodine areas, animal liver and kidney eating high frequency（ OR = 3.052,P〈0.05） was a risk factor. Conclusion In northern Jiangsu area, school-aged children＇ s urine iodine level basically meet the national standard of eliminating（ IDD）, but a proportion of investigated children show getting a low or high urine iodine level. The comprehensive intervention measure targeted on table salt and food, management of common salt, and interventionfor the iodine nutrition of children should be implemented to keep an appropriate level of iodine.
