摘　　要：目的评价山西省实施全民食盐加碘以来的防治效果及存在的问题,进一步完善可持续防治策略.方法1995-2003年的9年时间里,山西省地方病防治研究所对省辖的119个县(市、区)全部进行了碘缺乏病(IDD)监测.有4年是按照国家统一指导方案监测,其余间隙年山西省自行按PPS法抽样,产生30个监测点进行监测.监测指标包括8～10岁儿童甲状腺肿大率、儿童尿碘、盐碘及健康教育得分.结果(1)9年间,儿童甲状腺肿大率由1995年的10.9%下降到2003年的3.9%;(2)执行新的食盐加碘标准后,盐碘中位数从1999年的峰值49.7 mg/kg逐年下降到2003年的31.7 mg/kg,儿童尿碘中位数也由峰值407.5μg/L逐年下降到2003年的263.6 μg/L,尿碘值在100～300 μg/L的比率由低谷值24.6%逐年上升到2003年的51.1%;(3)9年间,合格碘盐食用率为48.3%～93.1%,碘盐覆盖率为90.5%～99.6%;(4)5年级学生和家庭主妇的IDD健康教育问卷知晓率均有逐年下降趋势.结论(1)自2000年山西省阶段性IDD消除目标实现以后,各项指标得到明显的提高,一直处于可持续消除IDD状态;(2)建议将食盐加碘执行标准改为(30±10)mg/kg,即能保证且适合各类人群的碘营养需求;(3)非碘盐冲击市场的现象始终存在,IDD健康教育工作需要继续加强.Objective To explore the controlling effects and existing problems of the program of universal use of iodized salt on controlling and preventing i odine deficiency disorders(IDD) in Shanxi Province since 1995. Methods Survei llance on IDD in all counties of Shanxi was carried out each year by the Shanxi institute for endemic disease prevention and treatment from 1995 to 2003, using the national unified measurement of surveillance in four years and population pr oportional probability sampling method to select 30 experimental spots in the re maining 5 years. Indexes including thyroid goiter, urinary iodine, salt iodine, health education were investigated and analyzed. Results (1)The total goiter rat e was decreasing each year, from 10.9% in 1995 to 3.9% in 2003. (2)After adoptin g the new national salt iodized criterion, the median salt iodine was decreased each year from the peak of 49.7 mg/kg in 1995 to 31.7 mg/kg in 2003. The median of urinary iodine lowered year by year from the peak of 407.5 μg/L in 1995 to 263.6 μg/L in 2003, while the percentage of urinary iodine within 100 ～ 300 μg/L was increased from the lowest level of 24.6% in 1995 to 51.1% in 2003. (3) During the past 9 years, consumption rate of qualified iodized salt ranged from 48.3% to 93.1%, the coverage rate of iodized salt ranged from 90.5% to 99.6%.(4) Students and housewives knew the IDD knowledge in a dropping tendency year by ye ar. Conclusions (1)All indicators have been obviously improved in Shanxi Provinc e since 2000, revealing that the goal of eliminating IDD has been achieved and w e are in a fine state of consistently eliminating IDD. (2)After changing the iod ized criterion to(30 ± 10) mg/kg, the iodine nutrition is guaranteed and suita ble for all kinds of people. (3)The non-iodized salt problem has been still exis ting for 9 years, and the health education should be strengthened.
