摘要
目的评价全民食盐加碘实施10年来北京市碘缺乏病的预防效果,了解北京市城乡居民碘营养状况,掌握碘缺乏病病情消长趋势。方法采用人口比例概率抽样方法确定监测对象;B超和触诊法检测8- 10岁学生甲状腺大小;尿碘检测用改进的酸消化砷-铈触诊法;食盐含碘量检测按GB／T 13025．7-1999直接滴定法。结果儿童尿碘中位数235．6μg／L,尿碘值<50μg／L的儿童占0．5％;盐碘均值32．1 mg／kg,碘盐覆盖率93．0％,合格碘盐食用率913％;8-10岁儿童甲状腺肿大率1．2％;儿童智商均值114．07。结论北京市学龄儿童碘营养状况达到适宜水平;北京市已经实现了消除碘缺乏病的目标。
Objective To evaluate the effect of prevention program on IDD since the universal salt iodization was performed 10 years ago, and to investigate the iodine nourishment of Beijing residents and the trend of IDD prevalence. Methods According to ＂National IDD Surveillance Project＂ issued by The Minister of Health of PRC, surveillance was carried out . The monitored subjects were chosen using population ratio stratification sampling method, the volume of the thyroid of 8 - 10 years old schoolchildren was detected by B-ultrasound or palpation, urinary iodine was measured by chloric acid digestion followed by a colorimetic ceric-arsenic assay, household table salt was measured using direct titration stipulated by the standard of GB/T 13025.7-1999, meanwhile Chinese improved Raven＇s test was used to test the intelligent quotient. Results The median of urinary iodine was 235.6 μg/L and the urinary iodine was lower than 50 μg/L in 0.5% of all the children. The averaged salt iodine was 32.1 mg/kg while 91.3% of all the consumed iodized salt was qualified. The prevalence rate of goiter in children aged 8 - 10 was 1.2%. The mean of intelligence quotient was 114.07. Conclusions The iodine nourishment in school children in Beijing has reached ideal level. The goal of eliminating IDD has been accomplished in Beijing.
