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＜ 100 μg/L为碘缺乏,100～ 199 μg/L为适宜量,200～299 μg/L为超过适宜量,≥300 μg/L为碘过量.结果共采集盐样34 808份,盐碘中位数为31.55 mg/kg,碘盐覆盖率为99.18％(34 521/34 808),合格碘盐食用率为97.12％(33 805/34 808)；共采集儿童尿样11 967份,尿碘中位数为244.0μg/L,其中＜50μg/的占2.6％(312/11 967),50～99 μg/L的占6.9％(823/11 967),100 ～ 199 μg/L的占26.3％(3145/11 967),200～299 μg/L的占28.7％(3440/11 967),≥300μg/L占35.5％(4247/11 967).在市级水平,9个市儿童尿碘中位数在200 ～ 299 μg/L,2个市的儿童尿碘中位数在300～400 μg /L；在县级水平,119个县儿童尿碘中位数在100 ～ 199 μg/L的占15.1％(18/119),200 ～ 299μg/L的占63.9％(76/119)；≥300 μg/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,但下调空间不宜过大.

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 villages 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 μg/L was iodine deficiency,100 - 199 μg/L as appropriate,200 - 299 μg/L as more than appropriate,and ≥ 300 μg/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 aged 8 -10 was 244.0 μg/L,of which ＜ 50 μg/L acoounted for 2.6％(312/11 967),50 - 99 μg/L accounted for 6.9％(823/11 967),100- 199 μg/L accounted for 26.3％(3145/11 967),200 - 299 μg/L accounted for 28.7％(3440/11 967),and 300 μg/L or higher accounted for 35.5％(4247/11 967).The medians of urinary iodine in the 9 municipal cities were 200 - 300 μg/L,and other 2 cities were 300 - 400 μg/L At the county level,the medians urinary iodine of children of the 119 counties(cities,districts) were 100 - 199 μg/L that accounted for 15.1％(18/119),200 - 299 μg/L accounted for 63.9％(76/119),and 300 μg/L or higher accounted for 21％(25/119).Conclusions The iodine nutrition level of residents in Shanxi province is more than appropriate.The salt iodine concentration in Shanxi province needs to be reduced,but the space is not wide.
