目的了解重庆市人群碘营养状况,为科学防治碘缺乏病提供科学依据.方法 2009年,在重庆所有40个区(县)中,每个区(县)抽取9个乡(镇),每个乡(镇)中采集40份居民食用盐,采用直接滴定法检测盐碘;每个区(县)按照东、西、南、北、中5个方位各抽取1个乡(镇),每个乡(镇)抽取20名以上8～10岁儿童,采集尿样,用砷铈催化分光光度法测定尿碘.结果重庆市共抽取居民户食盐14 217份,含碘量中位数为29.2 mg/kg;碘盐覆盖率为98.90%(14 061/14 217),合格碘盐食用率为95.59%(13 590/14 217).共调查8～10岁儿童4050份尿样,尿碘中位数为247.20μg/L;<50μg/L者占4.60%(186/4050),50～99μg/L者占7.28%(295/4050),100～199 μg/L者占26.44%(1071/4050),200～299μg/L者占25.58%(1036/4050),300μg/L以上者占36.10%(1462/4050);各年龄组之间尿碘比较,差异无统计学意义(x2=3.77,P>0.05).以区(县)计算,尿碘中位数100～199μg/L有10个区(县),占25.00%;200～299μg/L有23个区(县),占57.50%;300μg/L以上的有7个,占17.50%;不同区(县)之间尿碘比较,差异有统计学意义(x2=441.95,P<0.01).结论重庆市人群碘营养充足,同时存在碘过量,需降低食盐加碘量.

Objective To investigate the nutritional status of iodine among residents in Chongqing, and to facilitate scientific prevention and control of iodine deficiency disorders. Methods Select 9 towns in each of the 40 districts (counties) in Chongqing, and collect 40 resident edible salt samples in each of the selected town to detect salt iodine by direct titrimetry. Select 5 towns on the site of the east, west, south, north and middle of every district (county), select 20 children aged 8 to 10 in each of the selected town to collect urine samples and detect urinary iodine by As-Ce catalytic spectrophotometric assay. Results The median of iodine of 14 217 salt specimens by household was 292 mg/kg with a coverage rate of qualified iodized salt of 98.90%( 14 061/14 217). The consumption rate of qualified iodized salt was 95.59%( 13 590/14 217). The median of urinary iodine for 4050 children aged 8 to 10 was 247.20μg/L, of which < 50 μg/L accounted for 4.60%(186/4050), 50-99μg/L accounted for 7.28% (295/4050), 100 - 199 μg/L accounted for 26.44% (1071/4050), 200 - 299 μg/L accounted for 25.58% (1036/4050), 300 μg/L or more, accounted for 36.10% (1462/4050). However, no significant difference was observed between different age groups(x2 = 3.77, P > 0.05). At district (county) level, the median of urinary iodine in 10(25.00%) districts (counties) was 100 - 200 μg/L, that in other 23(57.50%) districts (counties) was 200 - 300 μg/L, and that in other 7(17.50%) districts/counties was greater than 300 μg/L, and statistical significance was observed between different districts/counties (x2 = 441.95, P < 0.01). Conclusions Current iodine nutrition among residents in Chongqing is adequate. While there is excess, need to reduce the amount of salt iodization.
