目的了解和正确评价广西沿海地区孕妇及哺乳期妇女的碘营养状况,切实做好广西碘缺乏病防治工作。方法在2008年度广西碘盐监测中“碘盐三率”低于90%的5个沿海县区的18个乡镇,每乡镇抽2个行政村,对其中10~15户家庭的孕妇和哺乳期妇女进行尿碘检测及家庭食盐含碘情况调查。结果共调查5个县区213名孕妇及哺乳期妇女,其尿碘平均水平为123.4μg/L,仅有21.6%的孕妇及哺乳妇女尿碘浓度在150~250μg/L之间的适宜范围;5个县区孕妇及哺乳期妇女尿碘中位数在78.6~168.8μg/L之间,高于150μg/L的仅有海城区,不足100μg/L的有铁山港区和银海区;妇女家庭食盐无碘率高达49.8%,5个县区妇女家庭食盐无碘率在31.6%~68.6%之间,无碘率最高的是铁山港区达68.6%,北海市银海区和钦州市钦南区无碘率均在50%以上。结论广西5个沿海县区中孕妇及哺乳期妇女整体上未达碘营养适宜水平,该人群有超过半数的碘营养水平明显偏低;该地区的非碘盐率普遍较高,建议广西沿海县区将孕妇及哺乳妇女的碘营养监测纳入常规监测,加强健康宣传教育,落实碘盐防治措施,打击非碘盐冲销市场,提高碘盐覆盖率。 Objective To understand and correctly evaluate iodine nutrition status of pregnant women and lactating women in coastal area of ​​Guangxi and to effectively prevent and cure iodine deficiency disorders in Guangxi. Methods In 2008, 18 villages and towns in 5 coastal counties with “three rates of iodized salt and three rates of iodized salt” in Guangxi were surveyed. Two administrative villages were set up in each township, and pregnant women in 10 to 15 households Lactation women urine iodine detection and family salt iodine investigation. Results A total of 213 pregnant women and lactating women in 5 counties were enrolled. The average urinary iodine level was 123.4 μg / L. Only 21.6% of pregnant women and lactating women had urinary iodine concentrations between 150 and 250 μg / L. The median urinary iodine of pregnant women and lactating women in 5 counties was between 78.6 and 168.8 μg / L, and there were only Tieshangang and Yinhai districts of Haicheng and less than 100 μg / L higher than 150 μg / L; The iodine-free rate of salt for women was as high as 49.8%. The iodine-free rate of salt for women in 5 counties was between 31.6% and 68.6%. The highest rate of non-iodine rate was 68.6% for Tieshan Port Area. Yinhai District and Qinzhou Qinan District, iodine free rate is above 50%. Conclusion The pregnant women and lactating women in five coastal counties of Guangxi Province have not reached the optimum level of iodine nutrition as a whole, and more than half of the population has low iodine nutrition level. The non-iodized salt rate is generally high in this area, District will be pregnant women and lactating women into iodine nutrition monitoring routine monitoring, strengthen health education and publicity, implementation of iodized salt prevention and treatment measures to combat non-iodized salt write-off market, improve iodized salt coverage.
