摘　　要：目的掌握浙江省临海市8~10岁儿童的尿碘和甲状腺容积情况,评估儿童群体的碘营养水平,为制定消除碘缺乏病干预措施提供依据。方法2019年,采用系统抽样方法,在临海市东、西、南、北、中5个片区各抽取1所乡镇(街道)中心小学,每所小学至少抽取40名8~10岁儿童,采集儿童家庭食用盐盐样和日间1次即时尿样进行盐碘与尿碘检测,同时进行甲状腺B超检查。结果共采集盐样215份,盐碘中位数为21.0 mg/kg,碘盐覆盖率为57.2%(123/215),碘盐合格率为91.9%(113/123),合格碘盐食用率为52.6%(113/215)。共采集尿样215份,尿碘中位数为166.0μg/L,尿碘<50μg/L的占5.1%(11/215)。共检查215名儿童甲状腺,甲状腺肿大率为4.7%(10/215)。结论临海市8~10岁儿童总体碘营养水平处于适宜(100~199μg/L),甲状腺肿大率在碘缺乏病消除标准限值(5%)内,但碘盐覆盖率、合格碘盐食用率严重偏低。Objective To investigate the urinary iodine and thyroid volume of children aged 8 to 10 years in Linhai City Zhejiang Province,and evaluate the iodine nutrition level of children so as to provide a basis for formulating intervention measures to eliminate iodine deficiency disorders.Methods In 2019,a systematic sampling method was adopted to select 1 township(street)central primary school in each of the 5 areas in the east,west,south,north,and middle of Linhai City.At least 40 children aged 8 to 10 years were selected from each of the central primary schools in each township(street)to collect family edible salt samples and one-time urine samples during the day for salt iodine and urinary iodine testing,respectively,as well as thyroid B-ultrasound examination.Results A total of 215 salt samples were collected.The median salt iodine was 21.0 mg/kg,the coverage rate of iodized salt was 57.2%(123/215),the qualified rate of iodized salt was 91.9%(113/123),and the consumption rate of qualified iodized salt was 52.6%(113/215).A total of 215 urine samples were collected.The median urinary iodine was 166.0μg/L,and the proportion of urinary iodine<50μg/L accounted for 5.1%(11/215).A total of 215 children were examined,and the goiter rate was 4.7%(10/215).Conclusion The overall iodine nutrition level of children aged 8 to 10 years in Linhai City is at an appropriate level(100-199μg/L),and the goiter rate is within the standard limit for the elimination of iodine deficiency disorders(5%),but the coverage rate of iodized salt and the consumption rate of qualified iodized salt are seriously low.
