摘要
目的了解大连市碘缺乏病防治情况，为碘缺乏病的防治工作提供科学依据。方法2006—2010年，全市每县抽取5或9个乡，每乡抽4个村，每村抽15或8户居民，采集居民户家中的食用盐，进行盐碘含量测定；每年在各县分别采集孕妇、哺乳期妇女、婴儿和幼儿的日间随意尿样60份，检测尿中碘含量；2007—2009年抽取2～11个县，每个县抽取1所学校，每所学校抽取8～10岁儿童日间随意尿样100份，检测尿中碘含量；2006—2009年，每年抽取2～5个县，每县抽取2～5个学校，每个学校抽取100名8～10岁儿童检测甲状腺容积和智商水平。结果2006—2010年大连市共监测16012份居民户食用盐，平均碘含量范围为29．68～31．51mg／kg．居民合格碘盐食用率范围为97．24％一98．42％；共监测1398名孕妇、486名哺乳期妇女、473名婴儿和502名幼儿的尿样，尿碘中位数范围分别为129．3—189．6、114．6～190．6、148．5～298．5μg／L和144．4－187．3μg／L；共监测1657名学龄儿童尿样，监测1264名学龄儿童甲状腺容积和1197名儿童智商水平，尿碘中位数、甲状腺肿大率和智商范围分别为217．9—266．7μg／L、0～3．29％和110．4—117．2。结论2006—2010年全市居民户合格碘盐食用率均达到国家碘缺乏病消除标准，重点人群和学龄儿童碘营养总体上达到足量和超足量水平，甲状腺肿大率均〈5％，儿童智力水平逐年提高。但2009年哺乳期妇女和2010年孕妇、哺乳期妇女碘营养不足，今后仍需加强这两组人群的宣传和碘营养监测。
Objective To analysis the progress in prevention and control of iodine deficiency disorders （IDD） in Dalian and to provide a scientific basis for further prevention and control of the disease. Methods From 2006 to 2010, 5 or 9 townships were randomly sampled from each county in Dalian, 4 villages were sampled from each selected townships and 15 or 8 households were sampled from each selected villages for collecting salt samples and salt iodine level was determined by direct titration method. Sixty daytime urine samples from pregnant women, breast feeding women, infants and young children were collected, respectively, every year to detect urinary iodine level. From 2007 to 2009, 2 to 11 counties were sampled and from each selected county one school was sampled to collect 100 daytime urine samples of children aged 8 - 10 and iodine content was determined. From 2006 to 2009, 2 to 5 counties were sampled, from each selected county 2 to 5 schools were sampled and 100 children aged 8 to 10 in each selected school were sampled to detect intelligence quotient level and the thyroid volume. Results From 2006 to 2010, 16 012 copies of households＇ edible salt samples were monitored; the average iodine content was ranged 29.68 - 31.51 mg/kg, the rate of qualified iodized salt in household ranged from 97.24% to 98.42%. A total of 1398 copies of urine samples of pregnant women, 486 breast feeding women, 473 infants and 502 young children were monitored, and the median value of urinary iodine was 129.3 - 189.6, 114.6 - 190.6, 148.5 - 298.5 and 144.4 - 187.3μg/L, respectively. A total of 1657 urine samples were monitored, 1264 intelligence quotient level and 1197 thyroid volume of school-age children were determined, the median urinary iodine, thyroid goiter rate and intelligence quotient level was 217.9 - 266.7 μg/L, 0 - 3.29% and 110.4 - 117.2μg/L, respectively. Conclusions From 2006 to 2010, the city＇s households qualified iodized salt coverage rate has reached the national standard for elimination of iodine deficie
