摘　　要：目的分析食盐加碘量调整对儿童和孕妇碘营养水平的影响。方法对食盐加碘量为20~50mg/kg的2011年和食盐加碘量为21~39mg/kg的2014年常德市碘缺乏病监测中儿童及孕妇碘营养状况进行比对分析。结果 2011年、2014年分别检测居民户碘盐120、150份,盐碘含量中位数分别为29.3、26.3mg/kg,分别检测儿童尿样636、150份,尿碘中位数分别为339.0、276.5μg/L,尿碘〈100μg/L者所占比例分别为5.03%、1.33%,〉300μg/L的比例分别为62.40%、36.70%。8~10岁儿童甲肿率（B超法）分别检测120、150人,甲状腺肿大率分别为4.17%、0.00%,孕妇尿样分别检测45、60份,尿碘中位数分别为269.2、218.6μg/L,〈150μg/L的比例分别为20.00%、25.00%,〉500μg/L的比例分别为2.22%、3.33%。结论调整食盐加碘量后常德市儿童甲状腺肿大率、儿童和孕妇尿碘中位数均明显下降,儿童碘营养摆脱过量水平,但仍超过适宜量,孕妇碘营养适宜,人群中同时存在碘营养水平过量和不足的风险。Objective To analyze the impact on the iodine nutrition among children and pregnant women after adjusting the iodine content in iodine salt. Methods The status of iodine nutrition under the level of iodine in salt of 20-50mg/kg in 2011 and 21-39mg/kg in 2014 was analyzed. Results A total of 120 and 150samples of iodized salt were tested among households in 2011 and 2014respectively,the median was 29.3mg/kg and 26.3mg/kg.A total of 636 and 150children＇s urine samples were tested,the median of urine iodine was 339.0μg/L and 276.5μg/L respectively.The ratio of the children＇s urine iodine less than 100μg/L accounted for 5.03% and 1.33%,and those more than 300μg/L accounted for62.40% and 36.70%.The total goiter rate of the children measured with ultrasound B was 4.17%（120）and 0.00%（150）.A total of 45 and 60pregnant women＇s urine samples were tested,the median urine iodine was 269.2μg/L and218.6μg/L,the ratio of urine iodine less than 150μg/L accounted for 20.00%and 25.00%,and those more than 500μg/L accounted for 2.22% and 3.33%. Conclusion After iodine adjustment,the total goiter rate of the children,the median of the children and pregnant women＇s urine iodine dropped significantly.The iodine nutrition level among the children is no more over-excessive,but still more than the appropriate level.And the iodine nutrition is suitable for pregnant women in Changde city.The risks of excess and shortage of iodine nutrition level coexist in the population at the same time.
