江苏省居民盐碘浓度变化分析

Analysis on change in iodine concentration in salt at households in Jiangsu province

摘要:
目的掌握江苏省1997~2002年居民食盐碘浓度变化情况。
方法采用1997、1999、2001、2002年江苏省碘缺乏病监测资料进行分析。
结果居民户碘盐覆盖率、碘盐合格率从1997年的90.8%, 65.5%上升到2002年的97.9%, 96.3%, 碘盐浓度由1997年的(4851±2424)mg/kg下降为(3265±594)mg/kg, 碘盐覆盖率、合格率高于90%的地区逐渐增多。
结论全民食盐加碘工作在江苏省得到可持续发展.建议在轻度缺碘地区, 碘盐浓度可调整至(30±5)mg/kg。

Abstract:
Objective To examine the change in salt iodine concentration at households and to afford basic statistics for government decision-making.
Methods To analyze data on iodine concentration collected in biennial survey of iodine deficiency disorders(IDD)from 1997 to 2002 in Jiangsu province.
Results The coverage rate and adequacy rate of household iodized salt rose from 90.8%、65.5% in 1997 to 97.9%、96.3% in 2002, respectively.Mean concentration of iodine in salt dropped from(48.51±24.24)mg/kg in 1997 to(32.65±5.94)mg/kg in 2002.The number of areas where coverage rate and adequacy rate of iodized salt were all above 90% increased over the period of 1997 to 2002.
Conclusion Implementation of universal salt iodization was potentially sustainable.It was advised that amount of iodine added to salt in mild IDD areas could be reduced to be(30±5)mg/kg while still meeting the requirements.
