摘要
目的了解江苏省宿迁市孕妇碘营养状况,为科学补碘提供依据。方法2016年5月至2020年7月,每年在宿迁市各县(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)抽取为本地居民户且在当地居住半年以上的孕妇20名;采集孕妇家中食用盐盐样30 g、随意1次尿样5 ml,检测盐碘、尿碘含量。结果共检测孕妇家中食用盐盐样2483份,盐碘中位数为23.9 mg/kg;其中,碘盐2454份,碘盐覆盖率为98.8%;合格碘盐2383份,碘盐合格率为97.1%,合格碘盐食用率为96.0%。不同年份间碘盐覆盖率、碘盐合格率、合格碘盐食用率比较,差异均有统计学意义(χ^(2)=10.55、13.23、11.37,P均<0.05)。共检测孕妇尿样2483份,尿碘中位数为167.6μg/L,处于碘适宜水平;但2020年孕妇尿碘中位数为146.7μg/L,低于世界卫生组织/联合国儿童基金会/国际控制碘缺乏病理事会(WHO/UNICEF/ICCIDD,2007年)推荐的标准(150μg/L)。不同年份、孕期、地区间孕妇尿碘中位数比较,差异均有统计学意义(H=26.08、8.17、19.87,P均<0.05)。结论宿迁市碘盐覆盖率、碘盐合格率、合格碘盐食用率均符合国家碘缺乏病消除标准;孕妇碘营养处于碘适宜水平,但部分孕妇可能存在碘缺乏情况。
Objective To learn about the iodine nutritional status of pregnant women in Suqian City,Jiangsu Province,and to provide evidence for scientific supplementation of iodine of pregnant women.Methods From May 2016 to July 2020,five sampling districts were divided in each county(district)of Suqian City according to the oriation of east,west,south,north and center each year.One township(street)was selected from each district,and 20 pregnant women who lived in the local area for more than half a year were selected from each township(street).The 30 g of household salt samples of pregnant women and 5 ml of urine samples at random once were collected to test the salt iodine and urinary iodine content.Results A total of 2483 household salt samples of pregnant women were tested,and the median salt iodine was 23.9 mg/kg;among them,2454 were iodized salt,and the coverage rate of iodized salt was 98.8%;the qualified iodized salt was 2383,the qualified rate of iodized salt was 97.1%,and the consumption rate of qualified iodized salt was 96.0%.There were statistically significant differences in coverage rate of iodized salt,qualified rate of iodized salt and consumption rate of qualified iodized salt between different years(χ^(2)=10.55,13.23,11.37,P<0.05).A total of 2483 urine samples of pregnant women were tested,and the median urinary iodine was 167.6μg/L,which was at the appropriate iodine level.However,the median urinary iodine of pregnant women in 2020 was 146.7μg/L,lower than the WHO/UNICEF/ICCIDD recommendation standard(150μg/L).The differences of median urinary iodine of pregnant women in different years,pregnancy periods and regions were statistically significant(H=26.08,8.17,19.87,P<0.05).Conclusions The coverage rate of iodized salt,qualified rate of iodized salt and consumption rate of qualified iodized salt in Suqian City,meet the national standard for eliminating iodine deficiency disorders.Iodine nutrition of pregnant women in Suqian City is at an appropriate iodine level,but some pregnant women may have iodine deficiency.
