目的了解重庆市璧山县和云阳县2个县的碘缺乏病现状,为制订防治策略提供依据。方法采用整群随机抽样方法,检测重庆市2个县8～10岁学龄儿童的尿碘、家庭食用盐、甲状腺肿大率、智商(IQ)。结果检测尿样571份,尿碘中位数为261.47μg/L,尿碘水平<100和>300μg/L分别有33,214份,分别占5.78%,37.48%;检测食用盐556份,碘盐覆盖率、合格率、合格碘盐食用率分别为99.64%,94.77%和94.42%;分别有60,53人通过触诊法和B超法诊断为甲状腺肿大,分别占10.36%和9.15%。结论 2县普供碘盐的情况良好,但人群尿碘水平仍然偏高,甲状腺肿大率明显高于全国平均水平。
Objective To understand the status of iodine deficiency disorders in two counties of Bishan County and Yunyang County of Chongqing Municipality, and to provide evidence for the prevention and control strategies. Methods The cluster random sampling method was used to detect urine iodine, family edible salt, goiter rate and IQ in school-age children aged 8-10 in Chongqing. Results 571 urine samples were detected, the urinary iodine median was 261.47μg / L, urinary iodine levels <100 and> 300μg / L were 33,214, accounting for 5.78% and 37.48% respectively; The rates of passing rate, passing rate and qualified iodized salt were 99.64%, 94.77% and 94.42% respectively; 60,53 were diagnosed as goiter by palpation and B-ultrasonography, accounting for 10.36% and 9.15% respectively. CONCLUSIONS: The iodine and salt in 2 counties are in good condition, but the urinary iodine level in the population is still high, and the goiter rate is obviously higher than the national average.
