目的:了解贵州省儿童缺碘性甲状腺肿大发病情况。方法:按“人口比例概率抽样方法”(PPS)抽取14个县(市、区),每县随机抽取一村小学,每小学随机抽40名8~10岁儿童进行甲状腺B超检查,计算肿大率。结果:共调查8~10岁儿童563名,肿大7例,肿大率为1.25%,其中男性肿大率为1.03%,女性肿大率为1.47%,差异无统计学意义(x2=0.22,P>0.05);8、9、10岁组儿童甲状腺肿大率差异无统计学意义(x2=0632,P>0.05)。结论:贵州省8~10岁儿童甲状腺肿大率小于5%,说明碘缺乏病防治情况良好。
Objective: To understand the incidence of iodine deficiency goiter in children in Guizhou Province. Methods: A total of 14 counties (cities and districts) were selected according to “Probability of Population Probability Sampling Method” (PPS). One village primary school was randomly selected in each county. 40 children aged 8 to 10 were randomly selected for primary B- Calculate swelling rate. Results: A total of 563 children aged 8-10 years were examined. Seven cases were enlarged and the swelling rate was 1.25%. The male swelling rate was 1.03% and the female swelling rate was 1.47%, the difference was not statistically significant (x2 = 0.22 , P> 0.05). There was no significant difference in the goiter rate between the children of 8, 9 and 10 years (x2 = 0632, P> 0.05). Conclusion: The goiter rate of children aged 8 ~ 10 in Guizhou Province is less than 5%, indicating that the prevention and treatment of iodine deficiency disorders is good.
