摘　　要：目的了解并掌握2018—2019年湖南郴州市孕妇碘营养水平,为科学防治碘缺乏病提供依据。方法按照《湖南省碘缺乏病监测方案》要求,抽取郴州市全部11个县(市、区),每县按东、西、南、北、中各抽取一个乡(镇),每个乡(镇)每年至少抽取20名孕妇,采集尿样和家中食用盐样,分别采用直接滴定法和砷铈催化分光光度法测定尿碘和盐碘含量。结果 2018—2019年郴州市共调查孕妇2 205人,均无甲状腺疾病史和食用碘油史;检测食用盐2 205份,合格碘盐覆盖率为95.69%(2 110/2 205),达到消除碘缺乏病技术指标;共检测2 205份孕妇尿样,尿碘含量中位数为205.90μg/L,各县(市、区)孕妇尿碘含量差异有统计学意义(H=69.450,P<0.001),孕期10 w以下,10 w~,20 w~组和30 w及以上组尿碘含量差异有统计学意义(H=11.684,P<0.01)。结论郴州市孕妇碘营养水平处于适宜水平,但仍需持续加强碘缺乏病健康教育。Objective To understand and grasp the iodine nutrition level of pregnant women in Chenzhou city of Hunan province from 2018 to 2019,and provide basis for scientific prevention and control of iodine deficiency disorders(IDD).Methods According to the requirements of IDD Monitoring Program in Hunan Province,all 11 counties(districts,cities)were selected in Chenzhou city,1 township was randomly selected from each of the five areas divided in the direction of east,west,south,north and middle of each county.At least 20 pregnant women were selected from each township every year.Urine samples of the pregnant women were collected,and salt samples were taken from the house of the pregnant women.The iodine content in salt and urine samples were detected with the method of direct titration and As-Ce catalytic spectrophotometry,respectively.Results Totally 2205 pregnant women without the history of thyroid disease and iodine oil consumption were surveyed in Chenzhou city from 2018 to 2019,and 2205 salt samples were detected,with the coverage rate of qualified iodized salt of 95.69%(2110/2205),achieving the standard of IDD elimination.There were 2205 urine samples of the pregnant women were detected with the median of iodized content of 205.90μg/L,and the difference in iodine content of the pregnant women was statistically significant(H=69.450,P<0.001)among different counties(cities,districts).The iodized contents in urine samples of the pregnant women were of statistical difference(H=11.684,P<0.01)in different gestational period less than 10 w,10 w-,20 w-,30 w and over.Conclusions The iodine nutrition level of the pregnant women is appropriate in Chenzhou city,but the health education on IDD still needs persistently strengthening.
