目的 了解杭州市食盐加碘含量调整后,不同碘盐覆盖率地区学龄儿童碘营养状况.方法 在食盐加碘含量调整后,于2013年在杭州市下辖的12个县(区、市),每个县(区、市)按东、西、南、北、中划分5个抽样片区,在每个片区抽取1所小学,每所小学抽取40名8～10岁学龄儿童,触诊法检查甲状腺(WS 276-2007);采集儿童家中盐样,采用硫代硫酸钠直接滴定法(G-B 13025.7-2012)检测盐碘;采集儿童尿样,采用砷铈催化分光光度测定法(WS/T 107-2006)检测尿碘.并按碘盐覆盖率＜95％和≥95％进行地区分类,对二者的学龄儿童尿碘水平进行比较.结果 共检测盐样和尿样各2 395份,盐碘和尿碘中位数分别为23.50 mg/kg和164.75μg/L,儿童甲状腺肿大率和碘盐覆盖率分别为1.75％(42/2 395)和93.15％(2 231/2395).12个县(区、市)的碘盐覆盖率比较,差异有统计学意义(x2=153.13,P＜0.01).其中碘盐覆盖率＜95％地区的学龄儿童尿碘中位数为151.00μg/L,碘盐覆盖率≥95％地区则为173.50 μg./L,二者比较差异有统计学意义(x2=-5.28,P＜0.01).结论 在食盐加碘含量调整后,杭州市8～ 10岁学龄儿童碘营养总体处于适宜水平.但在不同碘盐覆盖率地区,儿童尿碘水平存在差异,应进一步提高碘盐覆盖率并加强健康宣教.
目的 瞭解杭州市食鹽加碘含量調整後,不同碘鹽覆蓋率地區學齡兒童碘營養狀況.方法 在食鹽加碘含量調整後,于2013年在杭州市下轄的12箇縣(區、市),每箇縣(區、市)按東、西、南、北、中劃分5箇抽樣片區,在每箇片區抽取1所小學,每所小學抽取40名8～10歲學齡兒童,觸診法檢查甲狀腺(WS 276-2007);採集兒童傢中鹽樣,採用硫代硫痠鈉直接滴定法(G-B 13025.7-2012)檢測鹽碘;採集兒童尿樣,採用砷鈰催化分光光度測定法(WS/T 107-2006)檢測尿碘.併按碘鹽覆蓋率＜95％和≥95％進行地區分類,對二者的學齡兒童尿碘水平進行比較.結果 共檢測鹽樣和尿樣各2 395份,鹽碘和尿碘中位數分彆為23.50 mg/kg和164.75μg/L,兒童甲狀腺腫大率和碘鹽覆蓋率分彆為1.75％(42/2 395)和93.15％(2 231/2395).12箇縣(區、市)的碘鹽覆蓋率比較,差異有統計學意義(x2=153.13,P＜0.01).其中碘鹽覆蓋率＜95％地區的學齡兒童尿碘中位數為151.00μg/L,碘鹽覆蓋率≥95％地區則為173.50 μg./L,二者比較差異有統計學意義(x2=-5.28,P＜0.01).結論 在食鹽加碘含量調整後,杭州市8～ 10歲學齡兒童碘營養總體處于適宜水平.但在不同碘鹽覆蓋率地區,兒童尿碘水平存在差異,應進一步提高碘鹽覆蓋率併加彊健康宣教.

Objective To explore the impact of iodine nutrition on children in areas with different iodized-salt covering rate after adjusting the iodine content in iodized salt in Hangzhou.Methods After adjusting the iodine content of salt,every county (area,city) of Hangzhou was divided into east,west,south,north and middle districts;one school was selected in each district,40 children aged 8-10 years old in each school were selected.The goiter rates of 8-10 years old students were examined (WS 276-2007).The 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.Areas were classified according to the coverage rate of iodized salt ＜95％ and ≥95％,and their urinary iodine levels were compared.Results A total of 2 395 samples were collected with a median salt iodine concentration of 23.50 mg/kg and a urinary iodine level of 167.45 μg/L.The goiter rate of children 8-10 years old was 1.75％ (42/2 395).The total iodized-salt covering rate was 93.15％ (2 231/2 395) and the difference was statistically significant between different districts and towns (x2 =153.13,P ＜0.01),but the level was less than 95％ in 6 areas.The urinary median iodine was 151.00 μg/L in the areas where the iodized-salt covering rate was less than 95％,lower than 173.50 μg/L in the areas where the iodized-salt covering rate was more than or equal to 95％ (x2 =-5.28,P ＜0.01).Conclusions After adjusting the iodine content of salt in Hangzhou,the iodine-nutrition status of 8 to 10 years old students is optimal.But the urinary iodine levels are different in areas with different iodized-salt covering rates,so the coverage of iodized salt at household level need to be enhanced and the health education should be strengthen.
