摘要
目的了解安徽省碘盐含量调整后，碘缺乏病的防治效果及人群碘营养状况。方法2014年．在安徽省采用人口比例概率抽样方法（PPS）抽取30个县（市、区），每个县（市、区）抽取1所学校。每所学校抽取50名8-10岁儿童，采集尿样和家中食用盐，检测尿碘和盐碘含虽，并对儿童进行甲状腺B超检查：在学校所在乡镇采集20名孕妇尿样和家中食用盐，进行尿碘和盐碘检测。盐碘检测采用直接滴定法，川盐及其他强化食用盐采用仲裁法（GB／T13025．7-2012）；尿碘检测采用砷铈催化分光光度方法（WS／T107．2006）。结果共采集儿童家庭食用盐1575份，盐碘中位数为23．77mg／kg，合格碘盐食用率为93．65％（1475／1575）；采集孕妇家庭食用盐600份，盐碘中位数为23．50mg／kg，合格碘盐食用率为96．33％（578／600）。共采集儿童尿样1575份．尿碘中位数为242．20μg／L；采集孕妇尿样600份，尿碘中位数为158．15μg,／L，有43．33％（13／30）的县（市、区）孕妇尿碘中位数〈150μg／L。检查8-10岁儿童甲状腺1575人，肿大率为3．75％（59／1575）。结论安徽省8-10岁儿童碘营养高于适宜水平，但未达到碘过量；部分县（市、区）孕妇碘营养存在不足的风险。
Objective To explore the iodine nutritional status of people after adjusting iodine content in iodized salt in Anhui Province. Methods In 2014, 30 counties （cities, districts） were selected in Anhui Province according to the probability ratio sampling method （PPS）, and one school was selected in each county （city, district）, and 50 children aged 8 - 10 years were selected in each school. Urine and household salt samples were collected, urine and salt iodine levels were tested, and thyroid was examined using B-ultrasound. In the township where the school was located, 20 pregnant women＇s urine samples and household salt samples were collected for urine and salt iodine detection. The salt iodine level was measured by direct titration, Chuan salt and other fortified salt iodine levels were determined by arbitration method （GB/T 13025.7-2012）. Urinary iodine was determined by arsenic- cerium catalytic spectrophotometry （WS/T 107-2006）. Results A total of 1 575 children＇s household salt samples were collected, the median salt iodine was 23.77 mg/kg, the qualified iodized salt consumption rate was 93.65% （1 475/1 575）; 600 household salt samples were collected from pregnant women, the salt iodine median was 23.50 mg/kg, the consumption rate of qualified iodine salt was 96.33% （578/600）. A total of 1 575 urine samples were collected from children, the median urinary iodine was 242.20 μg/L; six hundred urine samples were collected from pregnant women, and the median urinary iodine was 158.15 μg/L, 43.33% （13/30） of the counties （cities, districts） pregnant wowen median urinary iodine 〈 150 μg/L. A total of 1 575 thyroid glands were examined in children aged 8 to 10 years, and the thyroid enlargement rate was 3.75% （59/1 575）. Conclusion The iodine nutrition of children aged 8 - 10 years in Anhui Province is higher than the appropriate level, but the iodine is not in the excessive state, and the iodine nutrition of pregnant women in some counties （cities, districts） is insufficient.
