目的了解居民碘盐覆盖率低于80%地区的人群碘营养状况及影响因素,为制订今后的防治措施提供科学依据。方法根据《全国碘盐监测方案》,水碘和尿碘浓度检测采用砷铈催化分光光度测定法,盐碘含量检测采用直接滴定法。结果居民碘盐覆盖率在29.86%～69.66%之间,8～10岁儿童尿碘中位数217.24μg/L,监测乡水碘中位数在5.51～527.08μg/L之间。结论沧州市碘盐覆盖率低于80%地区的8～10岁儿童碘营养从总体看略高于适宜水平,与饮用水碘含量较高有关,今后的食盐加碘措施,要因地制宜,不同地区不同对待。
Objective To understand the status and influencing factors of iodine nutrition in people with iodized salt coverage of less than 80%, and to provide a scientific basis for formulating future prevention and treatment measures. Methods According to the “national iodine salt monitoring program”, iodine and urinary iodine concentration detection using arsenic cerium catalytic spectrophotometry, salt iodine content detection using direct titration. Results The coverage of iodized salt among residents ranged from 29.86% to 69.66%. The median of urinary iodine was 217.24μg / L in children aged 8-10 years. The median of monitoring iodine in rural areas was between 5.51-527.08μg / L. Conclusion The iodine nutrition of children aged 8-10 years old in Cangzhou with iodized salt coverage less than 80% is slightly higher than the appropriate level, which is related to the high content of iodine in drinking water. The salt iodization measures in future should be tailored to local conditions and different regions Different treatment.
