目的了解湖北省居民食用不同碘含量食用盐后,人群碘营养状况的变化特点,根据世界卫生组织推荐的人群碘营养状况评价标准,提出适合湖北省食用盐的适宜碘含量标准.方法根据2010年湖北省居民碘盐和尿碘监测结果,选择武汉市的新洲区、天门市和宜昌市的长阳县作为干预区.每个干预区选择2个乡(镇)作为干预点.采用盐碘含量为(15±3) mg/kg和(25±3)mg/kg的食用盐进行为期4个月的社区干预试验.在干预前及干预3、4个月时,每个干预点分别采集8～10岁儿童、孕妇和哺乳期妇女及18～ 45岁成人尿样各40份,进行尿碘含量检测.对不同人群干预前后的尿碘中位数进行分析和比较.结果干预3、4个月时,盐碘含量为(15±3)mg/kg的乡(镇),儿童尿碘中位数由干预前的294.2 μg/L降至185.6、195.7.μg/L,孕妇和哺乳期妇女由干预前的269.0 μg/L降至141.7、176.1 μg/L,成人由干预前的304.9 μg/L降至199.7、202.2μg/L;盐碘含量为(25±3)mg/kg的乡(镇),儿童尿碘中位数由干预前的301.1 μg/L降至229.7、253.8μg/L,孕妇和哺乳期妇女由干预前的261.4.μg/L降至196.6、206.5 μg/L,成人由干预前的379.7μg/L降至244.3、237.4 μg/L.结论根据世界卫生组织推荐的人群碘营养状况评价标准和干预前后各类人群尿碘中位数及居民人均日摄盐量的下降趋势,盐碘含量25 mg/kg相对比较适合作为湖北省盐碘调整后食用盐碘含量的平均水平.

Objective To know the changing characteristics of residents' iodine nutritional status after eating salt with different iodine concentrations in Hubei Province,according to the assessment standard of iodine nutrition recommended by WHO/UNICEF/ICCIDD provide a scientific standard for appropriate iodine concentration in edible salt.Methods According to inhabitants' salt and urine surveillance of Hubei in 2010,Xinzhou District,Tianmen City and Changyang County were selected for trial.Salt with two kinds of iodine content was used in 3 trial areas in 4 months for the study of community intervention.Before the intervention,3 months and 4 months after the intervention,urine samples of observed participants(40 from 8-10 old children,40 from pregnant women or lactating women and 40 from adults aged older than 18) were collected and tested.The urinary medians of different groups of people and at different times were calculated and compared.Results Three months and 4 months after the intervention,in those towns using iodized salt of (15 ± 3) mg/kg,the urinary medians of children,declined from 294.2 μg/L to 185.6,195.7 μg/L,respectively.The urinary medians of pregnant women or lactating women dropped from 269.0 μg/L to 141.7,176.1 μg/L.For adults aged 18 and older,the urinary medians changed from 304.9 μg/L to 199.7,202.2 μg/L.In those trial towns of using (25 ± 3)mg/kg iodized salt,the urinary medians of children,pregnant women or lactating women and adults older than 18 all went down from 301.1 μg/L to 229.7,253.8 μg/L,from 261.4.0 μg/L to 196.6 and 206.5 μg/L and from 379.7 μg/L to 244.3,237.4 μg/L,respectively.Conclusions According to the assessment standard of iodine nutrition recommended by WHO/UNICEF/ICCIDD and the decreasing of urinary iodine median and per capita daily salt intake,salt with 25 mg/kg iodine is suitable as the average level of salt iodine concentration after the adjustment in Hubei Province.
