摘　　要：目的了解山西省居民碘营养状况，为调整碘缺乏病防治策略与措施提供科学依据。方法在山西省11个市的119个县（市、区），除外高碘乡（镇），有9个以上乡（镇）的县（市、区），按东、西、南、北、中5个方位抽取9个乡（镇），其中中位抽1个，每个乡（镇）抽4个村、每个村抽8户居民；在有6～9个乡（镇）的县（市、区），按、东、西、南、北、中5个方位各抽取1个乡（镇）、每个乡（镇）抽4个村、每个村抽15户居民；在有5个或不足5个乡（镇）的县（市、区），抽取所有乡（镇），每个乡（镇）抽取4个行政村，每个行政村抽取15户居民。采集上述居民家中的盐样，盐碘测定采用直接滴定法。在119个县（市、区），按、东、西、南、北、中5个方位各抽取1个乡（镇），每个乡（镇）抽取8～10岁儿童20名，采集尿样，尿碘测定采用砷铈催化分光光度法。碘营养评价标准：尿碘〈100ug／L为碘缺乏，100—199ug／L为适宜量，200—299ug／L为超过适宜量，≥300ug／L为碘过量。结果共采集盐样34808份，盐碘中位数为31．55mg／kg，碘盐覆盖率为99．18％（34521／34808），合格碘盐食用率为97．12％（33805／34808）；共采集儿童尿样11967份，尿碘中位数为244．0ug／L，其中〈50ug／L的占2．6%（312／11967），50—99ug／L的占6．90／0（823／11967），100—199ug／L的占26.3％（3145／11967），200～299ug／L的占28．7％（3440／11967），≥300ug／L占35．5％（4247／11967）。在市级水平，9个市儿童尿碘中位数在200—299ug／L，2个市的儿童尿碘中位数在300—400ug／L；在县级水平，119个县儿童尿碘中位数在100—199ug/L的占15．1％（18／119），200～299ug/L的占63．9％（76／119）；≥300ug／L的占21％（25／119）。结论山西省居民碘营养总体上超过碘适宜量。碘盐浓度需要下调，但下调空间不宜过Objective To investigate the iodine nutritional status of residents in Shanxi province, and to provide a scientific basis for adjustment of control strategies and measures to iodine deficiency disorders （IDD）. Methods In the 11 cities and 119 counties （cities, districts）, except high water iodine townships, 9 townships were selected in each county according to their sub-area positions of east, west, south, north and center, 4 villages were sampled in each chosen township, and 8 households were selected in each chosen village in every chosen county （cities, districts） with 9 or more townships. In every chosen county （cities, districts） with 6 to 9 townships, 1 township was selected respectively in east, west, south, north and center sub-areas of the township, 4 villages were sampled in each chosen township, and 15 households were selected in each chosen village. In the county （cities, districts） with 5 or less townships, all township were selected, 4 villag.es were sampled in each chosen township, and 15 households were selected in each chosen village. Edible salt samples from these households were collected; iodized salt was determined by direct titration. In the 119 counties （cities, districts）, 1 township was selected, respectively, in east, west, south, north and center sub-areas in each county, and 20 children aged 8 - 10 in each of the selected townships were selected to collect urine samples and urinary iodine was determined by As-Ce catalytic spectrophotometry. Evaluation criteria： median urinary iodine 〈 100 ug/L was iodine deficiency, 100 - 199 ug/L as appropriate, 200 - 299 ug/L as more than appropriate, and ≥ 300 ug/L as iodine excess. Results Median iodine of the 34 808 household salt samples was 31.55 mg/kg. The coverage rate of qualified iodized salt was 99.18% （34 521/34 808） and the consumption rate of qualified iodized salt was 97.12% （33 805/ 34 808）. In the 11 cities, 119 counties（cities, ＇districts）, the median of urinary iodine of 11 967 children ag
