摘　　要：目的了解食盐加碘浓度调整后重庆市碘缺乏病现状和居民碘营养水平,为碘缺乏病防治提供科学依据。方法在重庆市各区县随机抽取9个乡镇,每个乡镇抽取180户居民,测定家中食用盐碘水平;随机抽取5个乡镇,每个乡镇抽取100例孕妇检查尿碘水平;各区县随机抽取5所小学,每所小学随机抽取40例8~10岁儿童,检查甲状腺、尿碘水平。结果全市39个区县检查居民食用盐7 022份,合格碘盐6 772份,合格碘盐食用率为96.44%;检测3 929例孕妇尿碘水平,尿碘水平中位数为194.00μg/L,其中100.00~<200.00μg/L占34.92%,200.00~<300.00μg/L占22.55%,≥300.00μg/L占25.94%;检查8~10周岁儿童7 909例,尿碘中位数为259.00μg/L,其中100.00~<200.00μg/L占24.20%,200.00~<300.00μg/L占30.45%,≥300.00μg/L占37.45%;对7 909例儿童进行了甲状腺检查,甲状腺肿大率为2.29%。结论 2015年在国家降低了食盐加碘浓度以后重庆市盐碘、尿碘指标仍达到了国家消除标准;儿童尿碘超过适宜水平;孕妇尿碘处于适宜水平。Objective To investigate iodine deficiency disorders （IDD） and iodine nutrition level among the residents in Chongqing after adjusting salt iodine concentration,to provide scientific basis for prevention and control of iodine deficiency disorders. Methods According to Chongqing plan calls for IDD monitoring technology in 2015,39 counties were selected for monitoring. In every county, 180 households were randomly selected from nine spot townships and salt iodine of whom was tested. One hundred pregnant women were randomly selected from 5 spot townships and urinary iodine of whom was tested. Two hundred students aged 8-10 were selected from five primary schools in every county, urinary iodine levels were detected and the thyroid content was measured. Results A total of 7 022 resident salt samples were examined and there were 6 772 qualified salt sampls. The rate of qualified iodized salt was 96.44%. A total of 3 929 urine specimen of pregnant women were tested, the median of urine iodine of pregnant women was 194.00μg/L,urine iodine of 100.00-199.99 μg/L accounted for 34.92% ,200.00-299.99 μg/L accounted for 22.55,and urine iodine above 300.00 μg/L accounted for 25.94%. And 7 909 students aged 8-10 were investigated and the goiter rate was 2.29 %. The median of urine iodine in children aged 8-10 was 259.00 μg/L, urine iodine of 100.00--199.99 μg/L accounted for 24.20% and urine iodine of 200.00-299.99 μg/L accounted for 30.45% ,urine iodine above 300.00 μg/L accounted for 37.45%. Conclusion In 2015, after the countries reduced salt iodine concentration, the salt iodine and urinary iodine have achieved the national standard for eliminating IDD in Chongqing. The iodine nutrition of children exceeds the adequate level,iodine nutrition of pregnant women is appropriate.
