摘要
目的 了解江苏省未参加过全省碘缺乏病病情监测的缺碘地区人群碘营养状况,为碘缺乏病防治工作提供科学依据.方法 2011年,在江苏省对未参加过全省碘缺乏病病情监测的县（市、区）开展8～10岁儿童尿碘及家中盐碘水平调查.每个县（市、区）按东、西、南、北、中5个方位各抽取1个乡镇,每个乡镇各抽取1所乡中心小学校,每个学校各抽取20名8～10岁儿童（男女各半）采集尿样和家中盐样.尿碘测定采用砷铈催化分光光度法（WS/T 107-2006）,盐碘测定采用《制盐工业通用试验方法》（GB/T 13025.7-1999）中的直接滴定法.碘营养判定依据国际卫生组织推荐的标准：儿童尿碘＜ 100 μg/L为碘不足,100～ 199 μg/L为碘适量,200 ～ 299 μg/L为超适宜量,≥300 μg/L为碘过量.结果 共调查76个碘缺乏县（市、区）,采集8～10岁儿童尿样7 523份,尿碘中位数为235.0 μg/L.在所有被调查的县（市、区）中,尿碘中位数在100～199μg/L的有22个,尿碘中位数在200～299μg/L的有42个,,尿碘中位数≥300μg/L的有12个.采集居民家中盐样7523份,盐碘中位数为29.68 mg/kg,其中泰州市盐碘中位数最高,为31.43 mg/kg;连云港市最低,为25.11mg/kg.76个县（市、区）居民碘盐覆盖率为98.6％（7 417/7 523）,碘盐合格率为98.6％（7 312/7 417）,合格碘盐食用率为97.2％（7 312/7 523）.结论 江苏省以往未参加过全省碘缺乏病调查的缺碘地区,碘缺乏病防治工作进展良好,人群碘营养总体充足,但有部分县（市、区）尿碘中位数处于较高水平.
Objective To investigate the iodine nutritional status of the crowd that did not participate in the iodine deficiency disorders （IDD） survey in iodine deficiency areas in Jiangsu Province so as to provide a basis for prevention and control of IDD.Methods Eight to ten years old children were chosen from the counties（cities,districts） of Jiangsu Province that did not participate in the IDD survey and urine samples of students and salt samples of their families were researched.In each county （city,district） one township （street） was selected according to 5 directions of east,south,west,north,center; in each township one primary school was selected and in each primary school 20 children aged 8-10 were chosen half of the male and female,to collect their urine samples and salt samples at their families.Urinary iodine was measured using arsenic cerium catalytic spectrophotometric method （WS/T 107-2006）,and salt iodine was measured using direct titration of universal test method in salt industry （GB/T 13025.7-1999）.Iodine nutrition criterion of international health organization recommended staindard：children urinary iodine 〈 100 μg/L as iodine deficiency,100-199 μg/L as iodine appropriate,200-299 μg/L as iodine more than appropriate,≥ 300 μg/L as iodine excess.Results A total of 7 523 urinary samples of 8-10 years old children were collected from 76 iodine deficiency counties （cities,districts）,and the median of urinary iodine was 235.0 μg/L.In all investigated counties （cities,districts）,the medians of urinary iodine of 22 counties（cities,districts） were 100-199 μg/L,42 counties（cities,districts） were 200-299 μg/L,and 12 counties （cities,districts） were ≥300 μg/L.A total of 7 523 salt samples were collected,and the median of salt iodine was 29.68 mg/kg; Taizhou City had the highest salt iodine median,which was 31.43 mg/kg; and Lianyungang City,the lowest,25.11 mg/kg.The coverage rate of iodized salt was 98.6%（7 417/7 523）; iodized salt qualification rate was 98.6% （7 312/7 417）; and consuming rate of qualified iodized salt was 97.2%（7 312/7 523） in 76 iodine deficiency counties （cities,districts）.Conclusions The progress in prevention and control of IDD in iodine-deficient areas that did not participate in IDD survey in the past is good in Jiangsu Province; the overall level of iodine nutrition of whole population is adequate.But the median of urinary iodine in some counties （cities,districts） is at a higher level.
