摘　　要：目的研究新标碘盐供应前后厦门市沿海8-10岁儿童和孕妇的碘营养变化情况,为下一步碘缺乏病防控策略调整提供实证依据。方法在新标碘盐供应前及食用新标碘盐后的第3、6、9个月调查厦门市翔安区8-10岁学生和孕妇的尿碘、尿比重、碘盐覆盖率、碘盐合格率、合格碘盐食用率和居民日人均食盐摄入量。结果自来水水碘含量为4.2μg/L,基线调查、第二、三次评估日人均食盐摄入量均数分别为5.7、6.9、6.9 g;基线调查、第一、第二、三次评估,8-10岁学生碘盐合格率和合格碘盐食用率都分别为97.1、93.1、98.0和98.0,盐碘中位数分别为28.7、24.7、24.0、25.3 mg/kg,尿碘中位数分别为132.0、177.7、181.7和134.5μg/L,尿比重均值分别为1.0157、1.0196、1.0213和1.0184;孕妇碘盐合格率分别为97.8%、84.6%、84.4%和90.2%,盐碘中位数分别为27.8、25.7、24.3和23.7mg/kg,尿碘中位数分别为103.8、128.5、138.9和100.2μg/L,尿比重均值分别为1.0123、1.0153、1.0180和1.0143;尿碘与采样季节、气候及尿比重有关,尿碘值与尿比重呈正相关关系。结论新标碘盐实施前后,8-10岁儿童碘营养总体处于适宜水平,但孕妇碘营养均不足,要采取措施加强孕妇碘营养,保障人群健康素质。Objective To investigate the variation of iodine nutrition among children aged 8 to 10 and pregnant women after the implement of new standard of iodized salt supply, and to provide evidence for the further adjustment of control strategy against iodine deficiency disease. Method Survey has been performed to acquire the urinary iodine, specific gravity, iodized salt coverage rate, iodized salt qualification rate, qualified iodized salt consumption rate and average daily salt intake among children aged 8 to10 and pregnant women in Xiamen city. It has been conducted for 3 times repeatedly with a regular interval of 3 months after the implement of new standard. Results The tap water iodine content was 4. 2 μg / L. The average daily salt intake of baseline survey, second and third assessment was 5. 7, 6. 9 and 6. 9 g respectively. The iodized salt coverage rates among children aged 8 to10 and pregnant women were all reached 100% in 4 assessments. Among children aged 8 to 10, iodized salt qualification rate and qualified iodized salt consumption rate for 4 assessments were 97. 1, 93. 1, 98. 0 and 98. 0 respectively. Median of iodine salt samples was 28. 7, 24. 7, 24. 0 and 25. 3 mg / kg, respectively. The median of urinary iodine was 132. 0,1 77. 7, 181. 7 and134. 5 μg / L,respectively. The mean of specific gravity was 1. 0184, 1. 0157, 1. 0196 and 1. 0213, respectively. Among the pregnant women, the iodized salt qualification rate and qualified iodized salt consumption rate of pregnant women were 97. 8, 84.6, 84. 4 and 90. 2%, respectively. Median of iodine salt samples was 27. 8, 25. 7, 24. 3 and 23. 7 mg / kg, respectively. Median of urinary iodine was 103. 8, 128. 5, 138. 9 and 100. 2 μg / L,respectively. Mean of specific gravity was 1. 0123,1. 0153,1. 0180 and 1. 0143, respectively. Urinary iodine was correlated with season of sampling, climate and specific gravity, and urinary iodine was positively correlated with specific gravity. Conclusion The iodine nutrition status of children aged 8 to 10 was remained in
