摘要
目的为了解厦门市居民碘盐食用情况和部分重点人群碘营养水平,为采取针对性防控措施提供依据。方法选择厦门市思明、集美、翔安3个区作为调查点,开展居民家中饮用水水碘、盐碘,孕妇、8~10岁儿童的尿碘检测,居民食盐摄入量、8~10岁儿童甲状腺肿大和甲状腺结节发现情况调查。结果 3个区饮用水水碘均值均小于10μg/L,居民户碘盐覆盖率为98.44%,合格碘盐食用率为97.22%,8~10岁儿童甲状腺肿大率小于5.00%、甲状腺结节发现率为10.43%、尿碘中位数为181.73μg/L,其中〈50μg/L占5.58%,处适宜水平;孕妇尿碘中位数为136.55μg/L,处碘营养不足状态。结论厦门市仍为缺碘地区,碘缺乏病防控各项指标继续保持在消除标准,但孕妇处碘营养不足状态。
Objective To understand dietary conditions of iodized salt and iodine nutrition status in key populations in Xiamen city,so as to provide scientific basis for taking pertinent preventive and control measures. Methods Iodine concentrations in drinking water,salt,urine among pregnant women and children aged 8-10 years old were tested in Siming,Jimei and Xiang’an districts.Investigations on iodized salt intakes,thyroid enlargement among children aged 8-10 years old and thyroid nodule prevalence were also taken. Results The mean drinking water iodine concentration in the investigated areas was less than 10μg/L.Iodized salt coverage was 98.44%,and qualified iodized salt intake rate was 97.22%.Less than 5.00% of children aged 8-10 years old had thyroid enlargement,10.43% had thyroid nodules,medium urine iodine concentration was 181.73μg/L,5.58% of child urine concentrations were less than 50μg/L.Iodine nutritional status among children in Xiamen city was considered adequate.However,pregnant women in these areas had insufficient iodine nutritional status,with a medium urine iodine concentration of 136.55μg/L. Conclusion Xiamen city is still an area in lack of natural iodine.Indicators for controlling iodine deficiency disorders have been kept at the eliminated level.However,iodine nutritional status is insufficient among pregnant women.
