摘要
目的 分析陕西省碘缺乏病防治效果,为制订可持续消除碘缺乏病策略提供依据.方法 1995、1997、1999、2002、2005和2011年,采用人口比例概率抽样方法（PPS）,在陕西省抽取30个县（市、区）,每个县（市、区）抽取1所小学,每所小学抽取42名8～ 10岁儿童,用触诊法和超声法检查甲状腺情况,定量检测其家中食盐的碘含量.同时采集12名8～10岁儿童尿样,检测尿碘含量.2011年在上述抽中的学校附近,选择3个乡（镇,街道办事处）,每个乡（镇,街道办事处）抽取孕妇和哺乳期妇女各5人,采集其任意1次尿样,检测尿碘.在全省其余的77个县（市、区）,每个县（市、区）按东、南、西、北、中划分为5个片区,每个片区抽取1所小学,每所小学抽取15名学生,用3日称重法对其家庭成员做摄盐量调查.结果 8～ 10岁学生触诊法甲状腺肿大率由1995年的23.9％（574/2 400）逐渐下降到2011年的4.5％（57/1 260）.陕西省居民合格碘盐食用率由1995年的24.7％（593/2 400）逐年上升到201 1年的98.1％（1 236/1 260）,且从2005年以后连续保持在95.0％以上;1999年以后8～ 10岁儿童尿碘中位数范围为253.0 ～ 288.0μg/L,且尿碘大于300.0 μg/L的比例范围为39.3％（141/359）～59.9％（238/398）,处于超适宜状态.哺乳期妇女和孕妇尿尿碘范围为12.4～1500.0 μg/L,中位数为235.5 μg/L,处于适碘状态,尿碘＞250μg/L的占46.1％（416/902）.平均每人每天摄碘量为（9.5±3.2）g.结论 陕西省防治碘缺乏病措施落实较好,各项指标达到国家持续消除碘缺乏病标准.但是人群碘营养处于超适宜水平,可适当下调盐碘含量.
Objective To analyze the effectiveness of control measures on iodine deficiency disorders （IDD）,and to perfect the continued eliminating program of IDD control in Shaaxi Province.Methods In 1995,1997,1999,2002,2005 and 2011,by using probability proportionate to size sampling（PPS） method,30 counties （cities,districts） in Shaaxi Province were selected,and one school was chosen from each county（cities,districts）; in each school 42 children aged 8-10 were selected to measure their thyroid volumes and collect salt samples from their homes for determination of iodine content.Twelve out of the 42 children were selected to detect their urinary iodine content.In 2011,3 townships （towns,street offices） were selected near schools,and 5 pregnant and 5 lactating women were chosen,respectively,to test their urinary iodine content.In others 77 counties （cities,districts） of Shaanxi Province,each county（cities,districts） was divided into 5 areas according to their locations of east,south,west,north,and middle,and one school was chosen in each area; 15 students were sampled in each school,and the average daily salt intake of domestic residents of their family members was measured by 3 days weighing method.Results The goiter rat of children aged 8-10 was decreased from 23.9%（574/2 400） to 4.5% （57/1 260） examined by palpation.The qualified rat of iodized salt was increased from 24.7% （593/2 400） to 98.1%（1 256/1 260） in 1995 to 2011,and kept at higher than 95.0% since 2005.The urinary iodine medians were between 253.0 and 288.0 μg/L since 1999,and 39.3%（141/359）-59.9%（238/398） of them were more than 300 μg/L,which were in the over appropriate status.The urinary iodine content of pregnant and lactating women were between 12.4 and 1500.0 μg/L,which median was 235.5 μg/L,belonged to the appropriate status,and 46.1% （416/902） of them were more than 250 μg/L.The average daily salt intake of each person was （9.5 ± 3.2）g.Conclusions The control measurements for IDD are wel
