摘　　要：目的了解在碘缺乏病有效控制下新疆成人碘营养现状。方法于2017年采用分层整群随机抽样方法,在新疆确定水碘含量中位数<10μg/L和≥10μg/L的城市和农村共10个调查点,从抽取的调查点采集饮用水进行水碘含量检测;在各调查点随机抽取30户居民中18岁以上成人,开展膳食碘摄入量调查,并检测家庭食用盐碘和成人尿碘含量。结果新疆水碘含量中位数(四分位数)为4.4(2.3, 13.6)μg/L,家庭食用盐碘含量为27(24, 30)mg/kg,成人尿碘含量为168(103, 259)μg/L;全区成人膳食碘平均摄入量为312μg/d。结论新疆成人碘营养状况和膳食碘摄入量总体达到适宜水平,但水碘含量相对较低、经济状况较好的城市成人,发生碘缺乏的风险较高;经济状况较差的农村和城市,成人对碘盐的依赖程度更高。OBJECTIVE To understand the iodine nutrition status of adults in Xinjiang Uygur Autonomous Region under the effective control of iodine deficiency disease. METHODS Using stratified cluster random sampling method, in the district to determine water iodine median<10 μg/L and ≥10 μg/L of urban and rural areas, a total of 10 survey points, deals from the collecting water deals of extracting water iodine content detection. Adults over 18 years old were randomly selected from 30 households at each survey site to carry out a survey on dietary iodine intake, and the contents of dietary salt iodine and adult urine iodine were tested. RESULTS The median iodine content in water in Xinjiang Uygur Autonomous Region was 4.4(2.3, 13.6)μg/L. The median iodine content of household salt was 27(24, 30) mg/kg. The median urinary iodine content in adults was 168(103, 259)μg/L. The average dietary iodine intake of adults in the region was 312 μg/d. CONCLUSION The water iodine content in the environment outside Xinjiang Uygur Autonomous Region is relatively low, and the iodine nutritional status and dietary iodine intake of adults are generally at the appropriate level. However, urban adults with relatively low water iodine content and good economic status have a higher risk of iodine deficiency. Iodized salt is the main source of dietary iodine for adults in Xinjiang Uygur Autonomous Region. Adults in poorer rural and urban areas rely more heavily on iodized salt.
