目的了解阿克苏地区拜城县和乌什县哺乳妇女和婴幼儿碘营养现状。方法采用多阶段整群抽样法抽取新疆阿克苏地区拜城县和乌什县的251名哺乳期妇女和216名2岁以下婴幼儿,采用过硫酸胺消化-砷铈催化分光光度测定法检测所采集的1次随意尿碘含量;食用盐碘含量采用直接滴定法测定。结果共检测哺乳期妇女尿样251份,婴幼儿尿样216份。2县哺乳期妇女平均尿碘中位数为245.88μg/L,<150μg/L的占23.35%,婴幼儿平均尿碘中位数为195.58μg/L,<150μg/L的占35.1%;拜城县和乌什县哺乳妇女尿碘中位数分别为256.60μg/L和229.86μg/L,婴幼儿尿碘中位数分别为205.47μg/L和167.86μg/L;2县哺乳期妇女和婴幼儿的盐碘值中位数为34.46 mg/kg,盐碘含量均达到国家推荐标准(20~50 mg/kg)。结论该地区部分哺乳妇女和婴幼儿处于碘缺乏状态。建议应因地制宜适时采取有效的、有针对性的补碘措施,以防止因碘缺乏而造成下一代智力发育障碍的发生。
Objective To understand the status of iodine nutrition in lactating women and infants in Baicheng and Wushi counties in Aksu Prefecture. Methods A total of 251 lactating women and 216 infants under 2 years old from Baicheng County and Wushi County, Aksu Prefecture of Xinjiang Autonomous Region, were collected by multistage cluster sampling method. The samples were collected by ammonium persulfate digestion-arsenic-cerium catalytic spectrophotometry 1 free urinary iodine content; edible salt iodine content was determined by direct titration. Results A total of 251 urine samples from lactating women and 216 urine samples from infants and young children were detected. The median urinary iodine of lactation women in 2 counties was 245.88μg / L, accounting for 23.35%, <150μg / L, median urinary iodine was 195.58μg / L, 35.1% The urinary iodine median of lactating women in Chengxian and Wushi counties were 256.60μg / L and 229.86μg / L, respectively, and the urinary iodine median of infants and young children were 205.47μg / L and 167.86μg / L respectively. The median salt iodine value of infants and young children was 34.46 mg / kg, and the salt iodine content reached the national recommended standard (20-50 mg / kg). Conclusion Some lactating women and infants in this area are in an iodine deficiency state. Suggestions should be based on local conditions timely and effective take targeted iodine supplementation measures to prevent iodine deficiency caused by the next generation of mental retardation.
