广西沿海及盐田周边地区居民碘营养状况调查

目的了解和评价广西沿海地区和原盐产区居民的碘营养状况，切实做好广西碘缺乏病防治工作。方法在广西沿海三市的6个县（区）里抽取18个具备有沿海、带有海岸线，或存在有盐田的行政村和自然村（屯），对其育龄妇女进行尿碘检测，同时对其进行食盐合碘量情况调查。结果育龄妇女尿碘中住数为79．5μg/L，居住于靠海、沿海村屯的妇女和居住于盐田周边村屯的妇女尿碘中位数分别为110．7μg/L和64．3μg/L，新婚妇女、哺乳期妇女、其他妇女以及妊娠妇女的尿碘中位数分别为133．3μg/L、76．7μg/L、82．5μg/L,73．7μg/L；6县（区）居民的食盐含碘率为25．9％，沿海、靠海村屯居民和盐田周边居民的食盐有碘率分别为52．8％和6．7％。结论广西6个沿海及盐田周边县（区）育龄妇女整体上未达国家要求的碘营养适宜水平，妊娠妇女及哺乳期妇女的碘营养水平明显偏低。建议从源头上杜绝私盐流入市场，提高碘盐覆盖率；提高孕产妇及哺乳妇女重点人群的碘营养水平。

Investigation of the iodine nutrition status in the coastal and salt-producing areas in Guangxi

Aim To investigate the nutrition status of child-bearing age women in the coastal and salt-producing areas in Guangxi. Methods The urinary iodine tests were given to the child-bearing age women in 18 villages selected from the 6 urban counties in coastal or near to salt-producing areas and the iodine levels in their urine were determined. Results The median of the women＇s urinary iodine was 79.5μg/L. The medians of the women＇s urinary iodine in the coastal areas and the salt-producing areas were 110.7μg/L and 64.3μg/L respectively. The medians of the urinary iodine among the newly married women,the breast-feeding women,the pregnant women and the other women were 133.3μg/L,76.7μg/L, 73.7μg/L and 82.5μg/L respectively. The iodized salt coverage rate in the 6 counties was 25.9%. The iodized salt coverage rates in the coastal areas and the saltproducing areas were 52.8% and 6.7% respectively. Conclusions The iodine nutritional status of child-bearing age women in the 6 urban counties either coastal or near salt-producing areas in Guangxi,was in a whole below the national standard, especially in the breast-feeding women and the pregnant women Thus private salt be resolutely forbidden to increase the iodized salt coverage and to improve the iodine nutritional status of the women surveyed in Guangxi.
