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 investigate the status of iodine nutrition and its influencing factors in children aged 8 ~ 10 years in a certain area of northern Jiangsu and provide the basis for scientific iodine supplementation in school-age children. Methods A total of 724 school-aged children aged 8-10 years old in low, middle and high iodine areas in northern Jiangsu were stratified by stratified cluster analysis of water iodine. Water iodine, salt iodine in children’s family and urine iodine in children were detected. Some parents surveyed children . Results The median of iodine in low, middle and high iodine areas was 8.89, 38.52 and 189.25 μg / L respectively, and the median urinary iodine in children was 135.49, 183.62 and 448.99 μg / L, respectively, with statistical significance (P Value <0.01). In non-iodine areas, low iodine content is a risk factor for iodine deficiency in children (OR = 2.695). High awareness of iodine and health-related knowledge, instant noodles, eggs and high milk consumption frequency are the protective factors (OR = 0.611, 0.569,0.713,0.547, P <0.05). Men with overweight and obesity lacked the knowledge of iodine and health. High consumption of soy products was a risk factor for iodine excess (OR = 2.338, 5.032, 1.090 and 0.538, 1.414, P <0.05). High iodine areas, in addition to water iodine content, animal liver and kidney feeding frequency is a risk factor (OR = 3.052, P <0.05). Conclusion The urinary iodine level of school-age children in a certain area of northern Jiangsu Province basically meets the national standard of eliminating iodine deficiency disorders. However, children with low and high levels of urinary iodine still occupy a certain proportion. Should take iodine and health-related knowledge, salt management, nutrition, comprehensive interventions to maintain iodine nutrition in children at the appropriate level.
