摘要
目的了解山西省居民的碘营养状况,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,每个市随机抽查1～2个县,全省共抽取12个县,以县为单位,按东、西、南、北、中5个方位各抽取1个乡,每个乡各随机抽取1个村,每个村随机抽检20户居民食用盐含碘量,盐碘测定采用直接滴定法;在所抽取的每个乡各随机抽取1所小学,每所学校随机抽检20名8～10岁儿童,进行随意尿碘测定,尿碘测定采用砷铈催化分光光度法。结果 12个县共采集检测盐样1196份,盐碘中位数为32.1mg/Kg,合格碘盐食用率为96.72%;12个县共采集儿童尿样1199份,尿碘中位数为261.6μg/L,其中<50μg/L占1.3%,50～99μg/L占3.8%,100～199μg/L占22%,200～299μg/L占34.1%,≥300μg/L占38.8%;在调查的12个县中,儿童尿碘中位数在100～199μg/L的有1个,200～299μg/L的有9个;≥300μg/L的有2个。结论山西省居民碘营养水平总体上超过适宜量,但未过量,因碘过量引起群体性健康危害的风险很低;科学补碘的研究与实践工作应加强。
Objective To investigate the nutritional status of iodine among residents in Shanxi province, and to provide scientific basis for adjustment of control strategies and measures for iodine deficiency disorders（IDD）. Methods In the 11 cities, each city sampled one or two counties as survey point. In each county, 5 townships were randomly selected according to their sub - area positions of east, west, south, north and center, I village was sampled in each chosen township, 20 households were randomly in each chosen village. Edible sah from these households was collected; 1 school was sampled in each chosen township, 20 children aged 8 to 10 were selected to collect urine samples and detect urinary iodine by As - Ce catalytic spectrophotometric assay. Results The median iodine of 1 196 salt specimens by household was 32.1 mg/kg, the consumption rate of qualified iodized salt was 96.72%. The median of urinary iodine for 1 199 children aged 8 to 10 was 261.6 μg/L, of which 〈 50 μg/L accounted for 1.3%, 50 ～ 99 μg/L accounted for 3.8%, 100 ～ 199 μg/L accounted for 22%, 200 - 299 μg/L accounted for 34.1%, 300 μg/ L or more accounted for 38.8%. At county level, the median of urinary iodine in 1 county was 100 ～ 199 μg/L, that in other 9 counties was 200 ～ 299 μg/L, and that in 2 other counties was more than 300 μg/L. Conclusions The iodine nutrition level of residents in Shanxi is more than appropriate level but not excess. The disease risk of group aggregation induced by excessive iodine is very low; the research and practical work of iodine scientific supplementation should be strengthened.
