摘要
目的：横断面调查新疆乌鲁木齐市健康成年人群碘营养水平并分析其与民族、性别、年龄的关系。方法2013年5月在新疆乌鲁木齐市2个社区采用横断面整群抽样方法随机抽取2100名居民，资料完整者1835名，年龄18~84岁，平均（46.3±14.2）岁，采用砷铈催化分光光度法测定尿碘，同时采集居民家中食盐、饮用水，分别测定盐碘和水碘含量。根据世界卫生组织和国际控制碘缺乏病委员会标准，比较不同民族、不同性别、不同年龄成年人尿碘的差异。结果本地区水碘含量为3.14μg/L，盐碘含量为27.75 mg/kg，1835份尿样测定尿碘，尿碘中位数（MUI）133.4μg/L，碘缺乏人数占32.37%（595人），碘足量42.94%（788人），碘超足量14.44%（265人），碘过量10.19%（187人）。汉族成年人尿碘（137.9μg/L）水平高于维吾尔族（129.2μg/L），男性（135.1μg/L）和女性（133.6μg/L）碘水平差异无统计学意义（P〉0.05）。不同年龄组尿碘水平差异无统计学意义，但经组间比较，老年组与青年组和中年组尿碘水平均有统计学意义，随着年龄增大尿碘水平逐渐下降。结论乌鲁木齐市健康成年人群处于足量碘摄入状态；碘营养水平与民族有相关性，与性别无关；老年组碘营养水平低于其他年龄组人群。应对部分碘过量人群继续监测尿碘，逐渐减少碘摄入水平。
Objective To investigate iodine nutrition status in healthy adults in Xinjiang Urumqi city and their relationship to ethnicity, gender and age. Method A cross-sectional survey was performed in 2 100 residents of Xinjiang Urumqi 2 communities in May 2013, of which 1 835 healthy adults aged 18-84 years, mean age 46.3 ± 14.2 years were enrolled. Urine iodine with arsenic-cerium catalytic spectrophotometry and salt iodine and water iodine of the residents were measured. Result The water iodine content was 3.14 μg/L, salt iodine was 27.75 mg/kg, 1 835 urine samples were collected, the urinary iodine median（MUI） was133.4 μg/L, iodine deficiency accounted for 32.37% （595 cases）, iodine sufficient 42.94% （788 cases）, iodine super-sufficient 14.44%（265 cases）, iodine excess 10.19%（187 cases）. The urine iodine level in Han ethnic group was higher than those in Uygur adults, no significant difference was observed between men and women （P〉0.05）. Urinary iodine levels among different age groups had no statistical difference, but in the older groups the level was lower than that in young or middle age adults. The urinary iodine level decreased gradually with the age increasing. Conclusion There was a sufficient pattern of iodine nutrition levels in healthy adults in Xinjiang Urumqi; there was a correlation between the level of iodine nutrition and the ethnicity but not with gender;iodine nutrition level in older age group was lower than those in younger age groups. Monitoring the urinary iodine continually and decreasing iodine intake may be necessary for part of iodine excess population.
