2019年南昌市青云谱区8~10岁儿童碘营养水平监测结果分析

Analysis of Iodine Nutrition Monitoring Results of 8-10 Years Old Children in Qingyunpu District,Nanchang in 2019

目的了解2019年南昌市青云谱区8~10岁儿童碘营养水平,为改善该区儿童碘营养状况及碘缺乏病防治提供科学依据。方法2019年3月-8月2019年根据《全国碘缺乏病监测方案》(2016版)要求,将青云谱区监测点划分为5个片区,于2019年采用随机抽样的方法收集8~10岁儿童盐碘、尿碘、甲状腺等数据,分析青云谱区各片区居民碘盐监测结果,比较不同片区、年龄、性别儿童尿碘水平。结果本次共监测居民食用碘盐200份。碘盐覆盖率、碘盐合格率分别为100.00%、98.00%,未发现非碘盐;盐碘中位数为21.875 mg/kg;全区共检测8~10岁儿童尿样200份,其中尿碘中位数为220.05μg/L,尿碘分布范围在19.5~574.4μg/L;不同片区8~10岁儿童尿碘水平比较,差异有统计学意义(P<0.05);不同年龄儿童尿碘水平比较,差异无统计学意义(P>0.05);不同性别儿童尿碘水平分布,差异有统计学意义(P<0.05);未发现甲状腺肿大者。结论2019年青云谱区8~10岁儿童碘营养状态较适宜,尿碘水平在正常范围内,但不同监测片区、性别尿碘水平存在差异,建议该区继续加强以儿童为主的重点人群碘营养水平监测。

Objective To explore the iodine nutrition level of 8-10 years old children in Qingyunpu district,Nanchang city in 2019,and to provide scientific basis for improving the iodine nutrition status of children and iodine deficiency disease.Methods According to the requirements of the National Iodine Deficiency Disorders Monitoring Program(2016),the monitoring points in Qingyunpu District were divided into five areas.The data of salt iodine,urinary iodine and thyroid gland of 8-10 years old children were collected by random sampling in 2019,the iodine salt monitoring results of residents in each area of Qingyunpu district spectrum area were analyzed,and the urinary iodine levels of children in different areas,ages and genders were compared.Results Totally 200 portions of iodized salt were monitored.The coverage rate of iodized salt and the qualified rate of iodized salt were 100.00%and 98.00%respectively,and non-iodized salt was not found.Salt iodine median was 21.875μg/L;a total of 200 urine samples of 8-10 years old children were detected in the whole region,and the median urinary iodine was 220.05μg/L,urinary iodine distribution range was from 19.5-574.4μg/L;there were statistically significant differences in urine iodine levels among 8-10 years old children in different areas(P<0.05);there was no statistically significant difference in urine iodine levels among children in different ages(P>0.05).There was statistically significant difference in urinary iodine levels distribution among children in different genders(P>0.05).Goiter was not found.Conclusion The iodine nutritional status of 8-10 years old children in Qingyunpu district is appropriate in 2019,urine iodine levels are in the normal range.However,there are differences in urine iodine levels between different monitoring areas and genders.The region should continue to strengthen the monitoring of iodine nutrition levels in key population groups,especially children.
