目的了解和评价防治碘缺乏病措施效果,总结经验与不足。方法收集2002-2015年潍坊市碘缺乏病调查监测资料对居民食用盐碘含量、8~10岁在校学生尿碘含量和甲状腺肿大(简称甲肿)情况等内容进行分析。结果居民食用盐碘含量状况逐年好转2009年后碘盐合格率、碘盐覆盖率>97.00%,合格碘盐食用率>95.00%,非碘盐率<3.00%。各年度在校学生尿碘中位数波动于110.02~231.71μg/L,频数分布集中于100~299μg/L,各年度尿碘中位数比较差异有统计学意义(Z=41.76,P<0.05)。除2002、2006年外用肿率均<5.00%,各年度甲肿率比较差异有统计学意义(X~2=417.30,P<0.05)。结论自2009-2015年潍坊市盐碘含量、尿碘含量和甲肿等监测指标持续达到国家消除碘缺乏病标准。
Objective To understand and evaluate the effect of prevention and treatment of iodine deficiency disorders, summing up experience and deficiencies. Methods The survey data of iodine deficiency disorders in Weifang from 2002 to 2015 were collected to analyze the content of iodine in the residents and the urinary iodine content and thyroid enlargement of students aged 8 to 10 years. Results The iodine content of household salt gradually improved after 2009, the qualified rate of iodized salt, iodized salt coverage rate> 97.00%, qualified iodized salt rate> 95.00%, non-iodized salt rate <3.00%. The median urinary iodine of students in each year fluctuated between 110.02 ~ 231.71μg / L, and the frequency distribution concentrated on the range of 100 ~ 299μg / L. The median of urinary iodine in each year was significantly different (Z = 41.76, P <0.05 ). Except for 2002 and 2006, the edema rates were all less than 5.00%. There was significant difference between the two groups (X ~ 2 = 417.30, P <0.05). Conclusion From 2009 to 2015, monitoring indicators of salt iodine content, urinary iodine content and thyroid gland in Weifang City continue to reach the national standard of eliminating iodine deficiency disorders.
