摘要
目的掌握江西省居民碘营养水平，为制订碘缺乏病防控策略提供科学依据。方法采用资料回顾性方法，收集1995—2010年江西省碘缺乏病监测数据，分析8～10岁儿童甲状腺肿大率、尿碘频数分布。居民碘盐合格率、碘盐覆盖率、合格碘盐食用率。采用相关性分析的方法，分析儿童甲状腺肿大率（触诊法）与居民碘盐合格率、碘盐覆盖率、合格碘盐食用率的相关性。结果8～10岁儿童甲状腺肿大率（触诊法）由1995年的40．17％（482／1200）下降至2010年的0．80％（16／2000，x2=4．864，P〈0．05）；1995—2010年儿童尿碘中位数均〉2001．Lg／L，且〉300斗g／L的比例均超过25．00％，最高达58．01％（210／362）；盐碘中位数1995年最低，为17．77mg／kg，其余各年度盐碘中位数在29．30—39．10mg／kg；居民碘盐合格率、碘盐覆盖率、合格碘盐食用率分别由1995年的43．58％（452／1037）、86．42％（1037／1200）、37．67％（452／1200）升至2010年的97．95％（1916／1956）、99．95％（1956／1957）、97．90％（1916／1957），有随年份增长的趋势（x。值分别为5．240、6．118、5．631，P均〈0．05）。8～10岁儿童甲状腺肿大率与居民碘盐覆盖率、碘盐合格率、合格碘盐食用率存在相关性（r值分别为-0．833、-0．881、-0．918，P均〈0．05）。结论江西省居民碘营养已超过适宜水平，应该下调盐碘含量，保证居民适宜的碘营养水平。
Objective To master the level of iodine nutrition among population in Jiangxi province, and to provide a seientific basis for establishing the strategy for prevention and control of iodine deficiency disorders （IDD）. Methods Retrospective method was adopted to analyze the goiter rate and frequency distribution of urinary iodine of children aged 8 - 10, the qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in residents of Jiangxi province from 1995 to 2010. The method of correlation analysis was used to analyze the relationship between goiter rate of children （by palpation） and the qualified rate of iodized salt, iodized salt coverage rate and residents consumption rate of qualified iodized salt. Results The goiter rates（measured by the method of palpation） of children aged 8 - 10 were down from 40.17% （482/1200） in 1995 to 0.80%（16/2000） in 2010（~2 = 4.864, P 〈 0.05）. The median of urinary iodine of children was higher than 200 ~g,/L; the proportion of people whose urinary iodine content higher than 300 ~g/L was above 25.00% and the highest proportion was up to 58.01% （210/362） between 1995 - 2010. The minimum median of salt iodine was 17.77 mg/kg in 1995, and 29.30 - 39.10 mg/kg in other years. The qualified rates of iodized salt, the iodized salt coverage rates and the consumption rates of qualified iodized salt increased from 43.58% （452/1037）, 86.42% （1037/1200） and 37.67% （452/1200） in 1995 to 97.95% （1916/1956）, 99.95% （1956/1957） and 97.90% （1916/1957） in 2010, respectively; there was a growth trend over the years （~2 = 5.240, 6.118, 5.631, all P 〈 0.05）. The goiter rates of children were related to the qualified rates of iodized salt, the iodized salt coverage rates and the consumption rates of qualified iodized salt, and the correlation coe^eient（r） was - 0.833, - 0.881 and - 0.918 （all P 〈 0.05）, respectively. Conclusions The level of iodine nutrition among residents in Jiangxi province has already gone beyond the appropriate level, and the iodine concentration in salt should be cut to ensure the appropriate iodine nutrition level among people.
