摘要
目的分析贵州省铜仁市8~10岁儿童碘营养状况,为儿童科学补碘提供依据。方法2020-2022年,采用系统抽样方法,在铜仁市10个区县,每年每个区县按东、西、南、北、中划分5个片区,每个片区抽取1个乡镇(街道),每个乡镇(街道)抽取40名8~10岁非寄宿学生,进行家庭食用盐盐样和尿样的碘含量测定。分析比较各年份儿童盐碘、尿碘含量以及不同区县、性别儿童尿碘分布。另采用B超法测量部分儿童甲状腺容积,分析甲状腺肿大(甲肿)情况。结果2020-2022年共检测儿童家庭食用盐盐样6000份,检出碘盐5989份,碘盐覆盖率为99.8%;合格碘盐5750份,碘盐合格率为96.0%,合格碘盐食用率为95.8%;盐碘中位数为27.3 mg/kg,不同年份间盐碘中位数比较,差异有统计学意义(H=10.04,P<0.001)。共检测儿童尿样6000份,尿碘中位数为225.2μg/L,各区县儿童尿碘中位数比较,差异有统计学意义(H=85.73,P<0.001)。其中男童尿样3077份、女童尿样2923份,不同性别间尿碘中位数比较,差异有统计学意义(Z=-67.10,P<0.001),男童尿碘中位数高于女童(227.8比222.9μg/L)。共检查2000名儿童甲状腺,甲肿率为1.0%(21/2000)。结论2020-2022年铜仁市儿童合格碘盐食用率、尿碘含量及儿童甲肿率均达到国家消除碘缺乏病标准,总体碘营养处于超过适宜量水平(尿碘为200~299μg/L)。
Objective To analyze the iodine nutritional status of children aged 8-10 in Tongren City,Guizhou Province,and provide a basis for scientific iodine supplementation for children.Methods From 2020 to 2022,a systematic sampling method was adopted in 10 districts and counties of Tongren City.Each year,each district and county was divided into 5 districts based on east,west,south,north,and center.One township(street)was selected from each district,and 40 non boarding students aged 8 to 10 were selected from each township(street)to measure the iodine content of household salt and urine samples.The content of salt iodine in children of different yesas as well as the distribution of urine iodine in children of different districts and counties and different genders were analyzed and compared.Additionally,B-ultrasound was used to measure the thyroid volume of some children and the situation of thyroid enlargement was analyzed.Results From 2020 to 2022,a total of 6000 salt samples were collected and monitored from children's households,and 5989 samples of iodized salt were detected,the coverage rate of iodized salt was 99.8%;and 5750 samples of qualified iodized salt were found,the qualified rate of iodized salt was 96.0%,the consumption rate of qualified iodized salt was 95.8%;and the median salt iodine was 27.3 mg/kg,the difference in the median salt iodine among children between different years was statistically significant(H=10.04,P<0.001).A total of 6000 urine samples from children were tested,the median urinary iodine was 225.2μg/L,the median urinary iodine among children in different districts and counties were statistically significantly different(H=85.73,P<0.001);3077 male and 2923 female urine samples were tested,and the median urinary iodine between different genders was statistically significant different(Z=-67.10,P<0.001).The median urinary iodine of male samples were higher than those of female samples(227.8 vs 222.9μg/L).The thyroid gland of 2000 children was examined,and the rate of goiter was 1.0%(21/2000).Conclusions From 2020 to 2022,the consumption rate of qualified iodized salt,urinary iodine content and goiter rate of children in Tongren City have all met the national standard for eliminating iodine deficiency disorders.The overall iodine nutrition level exceeds the appropriate amount(urinary iodine of 200-299μg/L).
