碘缺乏病综合干预对学龄儿童甲状腺肿大率的影响

目的了解碘缺乏病综合干预对学龄儿童碘缺乏性甲状腺肿大率（甲肿率）的影响。方法采取食用碘盐、服用碘油丸、多部门协作、开设甲状腺门诊、系统化管理碘缺乏病、开展监测与流行病学调查、重点干预、广泛开展健康教育等综合干预措施。通过历年来学龄儿童甲肿率变化情况,来评价综合干预的效果。结果 1993年未采取特殊干预前学龄儿童甲肿率为23.40%,高于国家标准;补碘干预后,1997年甲肿率逐渐下降至5.01%,接近国家标准;采取综合干预后,甲肿率自1998年至2011年始终控制在5%以内。采取综合干预后与干预前及干预初甲肿率比较,差异有统计学意义（Ρ〈0.001）。结论易县所采取的碘缺乏病综合干预措施降低了甲肿率,实现了消除碘缺乏病目标。

Impact of comprehensive intervention of iodine deficiency disorders in goiter rate of school-age children

Objective To know the impact of comprehensive intervention in iodine deficiency disorders in school-age children.Methods Taking the consumption of iodized salt,oral iodized oil pills,multisectoral collaboration,start-up of thyroid clinics,systematic management of iodine deficiency disorders,surveillance and epidemiological investigation,focusing on intervention,extensive health education etc method of comprehensive interventions to investigate the goiter prevalence changes.Results The goiter rate of the school-age children who had not the special intervention was 23.40% in 1993,which was higher than the national standard.After iodine intervention,the goiter rate gradually decreased to 5.01% in 1997,which was close to the national standards.After comprehensive intervention,the goiter rate was always controlled within 5% from 1998 to 2011.Comparing the goiter rate after comprehensive intervention and before intervention,as well as the goiter rate after comprehensive intervention and after intervention,the differences were both statistically significant（Ρ〈0.001）.Conclusion Iodine deficiency disorders interventions can reduce the goiter prevalence in Yixian,achieving the goal of eliminating iodine deficiency.
