摘要
目的了解2009—2014年海宁市人群的碘营养水平及碘缺乏病病情现况，评价现行碘缺乏病防治措施的效果。方法在浙江省海宁市，每年不定时抽检批发食盐测定碘含量。2009—2011年，在全市东、西、南、北4个片区各抽取2个乡镇，中部片区抽取1个乡镇，每个乡镇抽取4个行政村，每个行政村抽检8户居民食用盐；2012—2014年，在全市东、西、南、北、中5个片区各抽取1个乡镇，每个乡镇抽取4个行政村，每个行政村抽检15户居民食用盐。在抽取的乡镇中．各抽取1所中心小学，每所小学抽取至少40名8—10岁学生，检测甲状腺容积；抽取至少20名8。10岁学生，采集即时尿样1份。检测尿碘。盐碘检测采用直接滴定法；甲状腺容积检测采用触诊法：尿碘检测采用砷铈催化分光光度法。结果2009—2013年，共抽检批发食盐339份，盐碘中位数范围为25．08～32．34mg／kg，均为合格碘盐。2009—2014年，共对1764户居民进行碘盐监测，盐碘中位数范围为23．40～28．15mg／kg，各年份合格碘盐食用率均〉90％；共对1241名8—10岁儿童进行甲状腺肿大率检查，各年份甲状腺肿大率均≤2％：共检测8～10岁儿童尿样708份，尿碘中位数范围为102．5～210．5μg／L，各年份尿碘〈50μg／L的比例均〈20％，适宜尿碘（100～〈200μg／L）的比例在2013、2014年有升高趋势。结论海宁市碘缺乏病取得了良好的防治效果。今后工作需要加强盐业市场监管，防止不合格食盐流入市场。
Objective To evaluate the effects of preventive and control measures on iodine deficiency disorders （IDD） in Hanning City in 2009 - 2014, we investigated the status of iodine nutrition level and IDD. Methods The wholesale salt was sampled irregularly for salt iodine test yearly in Haining City, Zhejiang Province. In the investigation, a random sampling was carried out as following： in 2009 - 2011, 2 towns were selected from each of the east, west, south, north areas of the city, 1 town was selected from the middle area of the city, 4 villages were selected from each town, and edible salt samples were collected in 8 households from each village. However, in the year of 2012 - 2014, only 1 town was selected from 5 areas （east, west, south, north, middle） of the city, still 4 villages were selected from each town, and then edible salt samples were collected in 15 households from each village. A central primary school was selected in each sampled town, at least 40 students aged 8 - 10 years old were selected for detection of thyroid volume, and at least 20 of these students＂ instant urine samples were collected for detecting urinary iodine. Salt iodine was tested using direct titration method, thyroid volume was measured by palpation method; urinary iodine was tested using arsenic cerium catalytic spectrophotometry. Results A total of 339 wholesale salt samples were tested, the median of salt iodine was 25.08 - 32.64 mg/kg in 2009 - 2013, and all the sampled wholesale salt samples were found to be qualified. A total of 1 764 household salt samples were collected in 2009 - 2014, the median of salt iodine was 23.40 - 28.15 mg/kg, and the consumption rates of qualified iodized salt were all higher than 90% each year. Monitoring results of 1 241 children aged 8 - 10 years old showed the goiter rates were all equal or lower than 2%, urinary iodine medians were 102.5 - 210.5 μg/L in 708 urine samples, the proportion of urinary iodine under 50μg/L was less than 20%, while the urinary iodine proportion in appropriate level in 100 - 〈 200 μg/L rose significantly over the last two years. Conclusions Measures with iodized salt as the principal way have good effects in Haining. However, the government needs to strengthen the regulation of salt industry market in the future to prevent unqualified salt come into the market.
