摘要目的：了解常州市碘缺乏病发展动态及防治效果，为制订有针对性的碘缺乏病防治措施提供依据。方法2012年在常州市所辖7个市、区采用人口容量概率比例抽样法抽取30所小学，每所小学抽取8~10周岁学生50名，检查甲状腺，并采集其尿样和家庭食用盐样，测定尿碘及盐碘。在小学所在地抽取30名孕妇和15名哺乳期妇女，采集尿样及检测尿碘；在小学所在村采集饮用水2份，检测水碘。采用调查方式问卷，对30名5年级儿童和5名家庭妇女进行健康教育调查。结果全市共检查8~10岁儿童1500名，甲状腺肿大率为0.07%（1/1500），尿碘中位数为224.81μg/L；检测孕妇尿样572份，尿碘中位数为148.93μg/L；检测哺乳期妇女尿样328份，尿碘中位数为147.48μg/L。检测盐样1500份，碘盐覆盖率为99.47%（1492/1500），合格碘盐食用率为97.67%（1465/1500），盐碘含量中位数为25.46 mg/kg。采集水样60份，水碘中位数为3.63μg/L。学生碘缺乏病防治知识知晓率为77.8%（2100/2700），家庭主妇碘缺乏病防治知识知晓率为88.0%（396/450）。结论常州市碘缺乏病防治效果显著，成绩稳固，建议密切关注特殊人群的碘营养水平。

abstractsObjective To investigate the current situation of iodine deficiency disorders and the effect of control measures in Changzhou City, Jiangsu Province, and to provide a basis for making up targeted control measures for iodine deficiency disorders. Methods In 2012, proportional probability sampling method(PPS) was used to select 30 primary schools in seven counties of Changzhou City;50 students aged 8-10 in each school were randomly selected to examine thyroid, and their urine and household salt samples were collected to detect iodine. Thirty pregnant and 15 lactation women were selected to detect their urine iodine in the town where the school was located in. Two drinking water samples were collected to detect iodine in the village where the school was located in. The questionnaire survey of health education was carried out among the children and the housewives. Results A total of 1 500 children were surveyed, and the rate of goiter was 0.07%(1/1 500); the median of urinary iodine was 224.81 μg/L. Five hundred and seventy-two pregnant women and 328 lactation women were surveyed, and the median of urinary iodine was 148.93 μg/L and 147.48 μg/L, respectively. Fifteen hundred salt samples were detected, and the coverage rate of iodized salt was 99.47%(1 492/1 500); the edible rate of qualified iodized salt was 97.67%(1 465/1 500); and the median of salt iodine was 25.46 mg/kg. Sixty water samples were collected, and the median of water iodine was 3.63 μg/L. The health education awareness rates were 77.8%(2 100/2 700) and 88.0%(396/450) of students and housewives, respectively. Conclusion The control effect of iodine deficiency disorders is significant in Changzhou City, and monitoring of iodine nutrition level of special populations should be strengthened.
