摘要
目的调查新碘盐标准实施对碘缺乏病防制效果影响,为今后制定防制策略提供依据。方法对新碘盐标准实施前后居民食用盐、8~10岁学生尿碘和甲状腺肿大率及孕妇尿碘进行监测,并对结果进行分析。结果 2011-2013年居民食用碘盐中位数依次为28.2、26.3、23.9 mg/kg,两两比较差异均有统计学意义(2012年VS 2011年:T=621.154,P<0.01;2013年VS 2012年:T=851.152,P<0.01;2013年VS 2011年:T=1472.310,P<0.01),呈现逐年递减趋势。三年间居民食用碘盐的总体概率分布差异有统计学意义(χ2=16.481,P<0.01),合格碘盐食用率分别为96.18%、95.33%、94.39%,同样呈逐年下降的趋势。2011-2013年8~10岁儿童尿碘中位数分别为172.00、163.00、169.00μg/L,差异有统计学意义(χ2=32.595,P<0.01),显示出下降趋势;2013年较2012年差异无统计学意义(2013年VS 2012年:T=-20.773,P>0.05)。三年间,儿童甲状腺肿大率差异无统计学意义(χ2=2.557,P>0.01)。2013年孕妇碘营养水平与2011年相比差异无统计学意义(T=982.00,P>0.01)。结论新碘盐标准在绍兴市实施后,食用盐碘含量确有降低,目前未对碘缺乏病防制效果产生显著影响。今后仍需持续关注儿童、孕妇等重点人群碘营养水平,加强对孕妇碘缺乏病相关知识宣传教育及孕期和哺乳期饮食指导工作。
Objective To investigate the effect of the new iodized salt standard on the prevention and control of iodine deficiency disorders and provide a basis for the future prevention and control strategy. Methods Iodine content of residents＇ edible salt, urine iodine level and goiter rate in children aged 8 - 10 years, urinary iodine level in pregnant women before and after the implementation of the new iodized salt standard were monitored, the results were analyzed. Results The decreasing trend showed from 2011 to 2013 in the median iodine content of residents＇ edible salt and qualified iodized salt edible rates（2012VS 2011 ：T =621. 154 ,P 〈0.01 ;2013VS 2012：T = 851. 152,P 〈0.01 ;2013VS 2011 ：T = 1472. 310 ,P 〈0.01 and χ2 = 16. 481 ,P 〈 0. 01 ）, median iodine contents of residents＇ edible salt were respectively 28. 2,26. 3 and 23.9 mg/kg, qualified iodized salt edible rates were respectively 96.18% ,95.33% and 94. 39% among the three years. The median urinary iodine in children aged 8 - 10 years from 2011 to 2013 were 172. 00,163.00 and 169.00μg / L,respectively. It showed a downward trend（χ2 = 32. 595 ,P 〈0. 01 ）. But the difference was not significant between 2013 and 2012 （2013VS 2012 ： T =-20. 773 ,P 〉 0.05 ）. Goiter rates in children aged 8 -10 years were no significant difference in the three years（χ2 = 2. 557 ,P 〉 0. 01 ）. It was no significant difference in levels of iodine nutrition of pregnant women between 2011 and 2012（ T =982.00,P 〉0. 01 ）. Conclusion After the implementation of the new standard in Shaoxing city, the content of edible salt iodine is indeed reduced. There is no significant effect on the prevention and control of iodine deficiency diseases. In the future ,it should continue paying attention to the iodine nutrition level of the key people such as children and pregnant women ,strengthening the education of iodine deficiency diseases in pregnant women,and guiding the diet of pregnancy and lactation.
