摘要
目的 探讨实施全民食盐加碘(USI)措施后,贵州省儿童甲状腺肿(甲肿)及其消长规律。方法 2001年4月采用点面结合的"典型调查"方法调查贵州省儿童的甲状腺肿情况,2003年10月采用群体追踪调查的方法,对2001年调查的同一人群开展甲肿消长情况的流行病学现况追踪调查。 结果 2003年共有效追踪调查了1 702名学生。其中在240例原检出Ⅰ度甲肿的学生中,139例转变为正常,转变率57.92％。15例转变Ⅱ度,转变率为6.25％。86例未改变,占35.83％。在28例原检出Ⅱ度甲肿的学生中,7例转为正常,2例转为Ⅰ度,总体转变率42.86％。在追踪调查的1 434名正常学生中,新发甲肿率为6.69％。结论 贵州省8-10岁儿童甲肿率逐年下降,但降幅非常缓慢,儿童甲肿多数会随时间推移自行减轻或恢复正常,只有少数会加重。
Objective To explore the growth and decline rule of endemic goiter of Guizhou province after universal salt iodination (USI). Methods A follow-up survey was conducted in the group of children aged 8-10 years old. Results 1 720 students were checked, and among 240 children with degree Ⅰ goiter, 139 children became normal with a convert rate of 57.92%. 15 changed into degree Ⅱ goiter with a convert rate of 6.25% and 86 unchanged, accounting 35.83%. 28 children with degree Ⅱ goiter were observed and the total convert rate (convert into normal and degree I) was 42.86%. The new occurrence (incidence) of endemic goiter was 6.69% among the 1 434 children with normal thyroid. Conclusions The incidence of endemic goiter in the children aged 8-10 years old in Guizhou province declines yearly, but very slowly. It is suggested that the new occurrence (incidence) of endemic goiter in the children aged 8-10 years old, or the incidence of endemic goiter in the children aged 8 years old be used as index for approval of goiter control.
