目的掌握宛城区碘缺乏病防治现状和病情消长情况,评价全区实施以食盐加碘为主的综合防治措施效果,为实现“十二五”规划持续消除碘缺乏病危害目标提供科学依据。方法 2011年11-12月采用分层随机抽取方法,在全区随机抽取5个乡,在每个乡再随机抽取1所小学,开展8~10岁儿童甲状腺肿大率调查,居民碘盐监测,对8~10岁儿童及哺乳期妇女(孕妇)进行尿碘监测及健康教育问卷调查。对居民进行饮水水碘监测。结果 2011年8~10岁儿童甲状腺肿大率为3.5%,智力中等以上占93%,智商均值为105.0,居民碘盐合格率为98%,水碘中位数为4.4μg/L,儿童、孕妇和哺乳期妇女尿碘中位数分别为194.6μg/L、235.8μg/L、156.0μg/L,学生和家庭主妇碘缺乏病防治知识知晓率分别为96.4%、88.0%,两者经检验差异有统计学意义(χ2=22.4,P<0.01)。结论宛城区外环境普遍缺碘,但通过实施以食盐加碘为主的综合防治措施后,居民碘营养适宜,碘盐合格率、8~10岁儿童甲状腺肿大率等监测指标均符合标准。实现了持续消除碘缺乏病目标。
Objective To grasp the status of prevention and treatment of iodine deficiency disorders in Wancheng District and to evaluate the effects of comprehensive prevention and treatment measures based on salt iodization in the whole district and to provide a scientific basis for achieving the target of continuing elimination of iodine deficiency deficiency in the 12th Five-year Plan . Methods From November to December in 2011, stratified random sampling method was used. Five townships were randomly selected in the whole district. One primary school was randomly selected from each township to conduct goiter survey among children aged 8 to 10 years. , On 8 to 10-year-old children and lactating women (pregnant women) for urinary iodine monitoring and health education questionnaire. Residents drinking water iodine monitoring. Results The prevalence of goiter in children aged 8 ~ 10 years was 3.5% in 2011, 93% in middle intelligence, 93.0% in intelligence, 105% in resident iodized salt, and 4.4 μg / L in water. In children, The urinary iodine median of pregnant women and lactating women were 194.6μg / L, 235.8μg / L and 156.0μg / L, respectively. The awareness rate of prevention and control of iodine deficiency among students and housewives were 96.4% and 88.0% The difference was statistically significant (χ2 = 22.4, P <0.01). Conclusion The external environment of Wancheng District is generally iodine-deficient. However, monitoring indicators such as suitable iodine nutrition, qualified rate of iodized salt and goiter rate of children aged 8 to 10 are all consistent with the comprehensive prevention and control measures mainly based on salt iodization.
