福建省1999年碘缺乏病监测报告

Analysis of IDD Surveillance in Fujian Province in 1999

为评价全民食盐加碘对福建省碘缺乏病的防治效果 ,于 1999年采用容量比例概率法 (PPS)在全省调查了 30个县 12 0 0名 8～ 10岁儿童的甲状腺肿大率 (B超法和触诊法 )、 1196份盐碘、 387份尿碘、 70 2份新生儿脐带血 TSH。结果显示该群体甲状腺肿大率 B超法为 6 . 2 5 % ,触诊法为 4 . 2 0 % ,尿碘中位数为 2 0 3. 9μg/ L,合格碘盐覆盖率 6 5 . 1% ,新生儿脐带血 TSH大于 5 mu/ L者占 2 1.7%。通过四年以全民食盐加碘为主的干预措施后 ,碘缺乏病病情已明显下降。

In order to assess preventive effect for IDD by universal salt iodization in Fujian Province, The goiter rate in 1 200 pupils,the urinary iodine levels in 387 pupils aged from 8~10 years and salt iodine levels of 1 196 households were examined from 30 counties selected randomly with method PPS and thyrotropin level of 702 samples neonatal cord blood were observed in Fujian Province in 1999. The goiter rate of children was 6.25% by B ultrasound and 4.2% by neck palpation,the median urinary iodine level was 203.9μg/L,and the effective proportion of household salt was 65.1%.Their percentage was 21.7%,whose thyrotropin level of neonatal cord blood was larger than 5 mu/L. According to the clinical and biochemical indicators,the prevalence rate of IDD declined considerably in Fujian Province after four years through the recommended intervention,universal salt iodization.
