为了解浙江省儿童碘营养水平的现状 ,进一步掌握全省消除碘缺乏病的进展情况和防治效果 ,1999年我们按照《全国碘缺乏病防治监测方案》要求 ,采用 PPS抽样方法在全省范围内抽取 30个县 (市、区 )各一所中心小学的 40名 8～10岁儿童进行碘营养水平调查。结果表明 ,12 0 0份学生家中盐碘中位数 40 .3mg/ kg ,其中合格碘盐 10 13份 ,合格率为84.42 % ;12 0 0名 8～ 10岁儿童甲状腺肿大率 ,触诊为 6 .40 % ,B超为 7.17% ;36 0份尿碘中位数为 2 0 7.0μg/ L ,其中高于 10 0 μg/ L的有 2 91份占 80 .83% ( 2 91/ 36 0 ) ;816份新生儿脐带血 TSH水平中位数为 2 .78m IU/ L,其中低于 5 m IU/ L的有 6 82份占 83.5 8% ;碘缺乏病健康教育问卷 6 0 0份 ,5年级学生组及格率为 88.17% ,15 0份家庭主妇组及格率为10 0 %。 1999年各项监测指标较 1995年和 1997年均有明显变化 ,表明浙江省儿童近期碘营养水平得到显著改善
In order to understand the status quo of children’s iodine nutrition in Zhejiang Province and to further grasp the progress and prevention and cure effect of iodine deficiency deficiency elimination in the whole province, in 1999 we adopted the PPS sampling method in accordance with the requirements of “National Iodine Deficiency Disease Prevention and Surveillance Program” A total of 40 children from 8 to 10 years of age from one central primary school in 30 counties (cities and districts) were selected to conduct iodine nutrition level survey. The results showed that the median of iodized salt was 40.3 mg / kg in 12 0 0 students, of which 10 13 were eligible for iodized salt with a pass rate of 84.42%; the goiter rate of 120 children aged 8-10 was palpated Of the total urinary iodine was 6.40% and the B ultrasound was 7.17%. The median of 36 0 urinary iodine was 20.7μg / L, of which, 91.0% The median of cord blood TSH levels in 816 newborns was 2.78 m IU / L, of which, 6 82 were 83.5 8% less than 5 m IU / L, and those of Iodine Deficiency Disorders Health Education Questionnaire 600 The passing rate of Grade 5 students was 88.17%, and the passing rate of 150 hostesses was 100%. The monitoring indicators in 1999 compared with 1995 and 1997 have changed significantly, indicating that children in Zhejiang Province recently iodized nutrition levels have been significantly improved
