目的 了解杭州市食盐碘含量调整后8～ 10岁学龄儿童的碘营养水平.方法 将杭州市及所辖12个县(区、市)按地理位置划分为城区、郊区和农村3类.采用人口比例概率抽样法(PPS),在每个县(区、市)按东、西、南、北、中5个方位划分5个片区,每个片区抽取1所小学,每所小学抽取40名8～10岁儿童(男女各半),采集家中盐样,采用硫代硫酸钠直接滴定法(GB 13025.7-2012)检测盐碘;收集上述学生尿样,采用砷铈催化分光光度测定法(WS/T 107-2006)检测尿碘.结果 全市共检测盐样2 725份,盐碘中位数、碘盐覆盖率、碘盐合格率、合格碘盐食用率分别为24.00mg/kg、94.35％(2 571/2 725)、91.02％(2 340/2 571)、85.87％(2 340/2 725),其中城区、郊区和农村的盐碘中位数分别为24.10、22.12、24.30mg/kg.共检测8～ 10岁儿童尿样2 664份,尿碘中位数为177.24μg/L,其中城区、郊区和农村的儿童尿碘中位数分别为175.00、178.55、178.00 μg/L;男性儿童尿碘中位数为183.00μg/L,女性儿童为170.50 μg/L.食用非碘盐及不合格碘盐时,城区、郊区和农村8～10岁学龄儿童尿碘组内比较差别有统计意义(x2值分别为18.652、14.686,P均＜0.05).在农村地区,食用不同类型碘盐的8～10岁学龄儿童尿碘组间比较差别有统计意义(x2=39.07,P＜ 0.05).结论 食盐碘含量调整后,杭州市8～ 10岁儿童碘营养总体处于适宜水平.

Objective To explore the impact of iodine nutrition on 8-10 years old children after adjusting the iodine content in iodized salt in Hangzhou.Methods Twelve counties (areas,cities) were divided into urban,suburban and rural areas in Hangzhou.By population proportion survey (PPS),every county(area,city) was divided into east,west,south,north and middle districts; one school was selected in each district; forty children (half male and half female) aged 8-10 years old in each school were selected; family salt and urine samples of each student were collected.The levels of salt and urinary iodine were measured by picric sodium thiosulfate titrimetric (GB 13025.7-2012) and spectrophotometer method (WS/T 107-2006),respectively.Results Two thousand seven hundred and twenty-five household salt samples were collected.The median of salt iodine,the iodized salt coverage rate,the qualification rate of iodized salt and the consumption rate of qualified iodized salt were 24.00 mg/kg,4.35％(2 571/2 725),91.02％(2 340/2 571) and 85.87％(2 340/2 725),respectively.The medians of salt iodine in urban,suburb and rural areas were 24.10,22.12,24.30 mg/kg,respectively.A total of 2 664 children urine samples were collected.The median of urinary iodine (MUI) of the children was 177.24 μg/L.The MUIs in urban,suburb and rural areas were 175.00,178.55,178.00 μg/L,respectively; in male was 183.00 μg/L and female was 170.50 μg/L.When non-iodized and unqualified iodized salt were taken,the differences of urinary iodine within groups were statistically significant in urban,suburb and rural areas(x2 =18.652,14.686,all P ＜ 0.05).In rural area,the difference of urinary iodine of 8-10 years old children who ingested different types of iodized salt was statistically significant(x2 =39.07,P ＜ 0.05).Conclusion After adjusting the iodine content of salt in Hangzhou,the iodine-nutritional status of 8-10 years old students is at a appropriatelevel.
