摘　　要：目的分析碘盐新标准实施后南昌市碘盐监测情况,为制订碘缺乏病防控策略提供依据。方法2013-2015年按照《江西省碘缺乏病监测方案(2012版)》,全市9个县(区)按东、西、南、北、中划分5个抽样片区,每个片区抽取1个乡镇(街道),每个乡镇(街道)抽取4个行政村(居委会),每个行政村(居委会)抽检15份居民户食用盐盐样。2016-2018年部分县(区)按照《全国碘缺乏病监测方案(2016版)》要求,按东、西、南、北、中划分5个抽样片区,每个片区抽取1个乡镇(街道),每个乡镇(街道)抽取1所小学,每所小学抽取8~10岁非寄宿学生40人(年龄均衡,男女各半),采集学生家中食用盐盐样,同时每个乡镇(街道)抽取20名孕妇,采集孕妇家中食用盐盐样,剩余县(区)按照《江西省碘缺乏病监测方案(2012版)》进行抽样。对采集盐样进行盐碘含量检测,计算碘盐覆盖率、碘盐合格率、合格碘盐食用率。结果2013-2018年碘盐覆盖率、碘盐合格率、合格碘盐食用率分别为99.52%(16122/16200)、95.83%(15449/16122)、95.36%(15449/16200),盐碘中位数为23.50 mg/kg;碘盐覆盖率2018年最低,为98.63%(2663/2700),不同年份间比较,差异有统计学意义(χ2=97.856,P<0.05);碘盐合格率和合格碘盐食用率均是2016年最低,分别为93.93%(2509/2671)和92.93%(2509/2700),不同年份间碘盐合格率和合格碘盐食用率比较,差异有统计学意义(χ2=65.090、81.053,P均<0.05);非碘盐率2018年最高,为1.37%(37/2700),不同年份间非碘盐率比较,差异有统计学意义(χ2=97.856,P<0.05);2013-2018年盐碘含量波动范围在0.00~64.67 mg/kg;2013-2018年碘盐覆盖率青云谱区和南昌县最高,均为100.00%(1800/1800),东湖区最低,为98.06%(1765/1800),不同县(区)碘盐覆盖率比较,差异有统计学意义(χ2=131.247,P<0.05);碘盐合格率青云谱区最高,为99.11%(1784/1800),西湖区最低,为93.16%(1674/1797),不同县(区)碘盐合格率比较,差异有统计学意义(χ2=12Objective To analyze the monitoring situation of iodized salt in Nanchang City after implementation of the new iodized salt standard,in order to provide a basis for formulating prevention and control strategy to iodine deficiency disorders.Methods From 2013 to 2015,according to"Jiangxi Province Surveillance Pilot Scheme of Iodine Deficiency Disorders(2012)",9 counties(districts)were selected for surveillance of iodized salt,every county(district)was divided into 5 sampling areas according to the east,west,south,north,and middle positions,and 1 township(street)was selected from each area,4 administrative villages(neighborhood committees)were selected from each township(street),and 15 samples of household salt were sampled from each administrative village(neighborhood committee).From 2016 to 2018,according to"National Surveillance Pilot Scheme of Iodine Deficiency Disorders(2016)",some counties(districts)were divided into 5 sampling areas according to the east,west,south,north,and middle positions,and 1 township(street)was selected from each area,1 elementary school was selected from each township(street),40 non-boarding students aged 8 to 10(aged balanced,half male and female)were selected from each elementary school,and salt samples from students'homes were collected and in each township(street)salt samples were collected from 20 pregnant women's homes.The remaining counties(districts)were sampled in accordance with"Jiangxi Province Surveillance Pilot Scheme of Iodine Deficiency Disorders(2012)".The iodine content of salt samples was detected,and the coverage rate,qualified rate and consumption rate of qualified iodized salt were calculated.Results From 2013 to 2018,the coverage rate of iodized salt,the qualified rate of iodized salt and the consumption rate of qualified iodized salt were 99.52%(16122/16200),95.83%(15449/16122)and 95.36%(15449/16200),respectively,and the median salt iodine was 23.50 mg/kg;the coverage rate of iodized salt in 2018 was the lowest[98.63%(2663/2700)],and the difference was statistica
