摘　　要：目的 了解丹阳市重点人群的碘营养状况及变化趋势,为调整补碘干预策略提供参考依据。方法 2016-2018年每年在丹阳市内5个方位随机抽取1个乡镇的8~10岁非寄宿学生48名和孕妇24名,收集其尿样本和家中食盐,采用直接滴定法和氧化还原滴定法检测盐中碘含量,砷铈催化分光光度检测尿中碘含量。结果 2016-2018年共检测食盐样本1 053份,盐碘中位数为21.8 mg/kg,碘盐覆盖率为98.86%,碘盐合格率为92.22%,合格碘盐食用率为91.17%,3年间盐碘中位数比较,差异有统计学意义(P<0.05)。检测8~10岁学生尿样本690份,尿碘中位数为232.1μg/L,3年间学生的尿碘中位数比较,差异无统计学意义(P>0.05)。检测孕妇尿样本363份,尿碘中位数为142.5μg/L,孕妇碘营养不足率为53.7%,3年间孕妇尿碘中位数比较,差异无统计学意义(P>0.05);2016年与2018年中孕妇碘营养不足率比较,差异有统计学意义(P<0.05)。结论 丹阳市重点人群碘营养状况逐渐趋于适宜的水平,但孕妇碘营养不足的情况仍较严重,应对孕妇加强宣传教育,增加科学补碘的来源和方法。Objective To understand the iodine nutritional status and changing trend of key population in Danyang City,provide basis for adjusting the intervention strategy of iodine supplementation.Methods From 2016-2018,48 non-boarding students aged 8-10 years old and 24 pregnant women were randomly selected from 5 locations in Danyang City every year.Urine samples and household salt were collected.Salt iodine content was measured by direct titration and redox titration,while iodine in urine was measured by arsenic and cerium catalytic spectrophotometry.Results From 2016-2018,a total of 1053 salt samples were tested,the median of salt iodine was 21.8 mg/kg,the coverage rate of iodized salt was 98.86%,the qualified rate of iodized salt was 92.22%,and the consumption rate of qualified iodized salt was 91.17%.The difference in salt iodine median was statistically significant among three years(P<0.05).690 urine samples of 8-10 years old students were tested,the median of urine iodine was 232.1 μg/L,and there was no statistically significant difference in median of urine iodine among the three years(P>0.05).363 urine samples of pregnant women were tested,the median of urine iodine was 142.5μg/L,and the rate of pregnant women with iodine deficiency was 53.7%.There was no statistically significant difference in median of urine iodine in pregnant women among the three years(P>0.05).There was a statistically significant difference in iodine deficiency rate of pregnant women between 2016 and 2018(P>0.05).Conclusion The iodine nutritional status of the key population in Danyang City gradually tends to the appropriate level,but the iodine nutritional deficiency of pregnant women is still serious.It is necessary to strengthen publicity and education for pregnant women and increase the sources and methods of scientific iodine supplementation.
