目的分析山东省缺碘地区8~10岁儿童甲状腺容积变化趋势。方法应用1997-2005年4次全省碘缺乏病监测的儿童甲状腺B超检查结果,对8~10岁儿童甲状腺容积的变化规律进行分析。结果总体儿童甲状腺肿大率逐年下降,触诊检查肿大率由1995年22.3%下降到2005年4.42%,B超检查由1997年7.75%下降到2005年3.25%。儿童甲状腺肿大率随年龄的增长而逐渐增高,儿童甲状腺容积随年龄的增长而增大。碘缺乏地区不同年龄组儿童甲状腺容积逐年回缩。甲肿儿童甲状腺容积无明显变化。结论山东省缺碘地区8~10岁儿童甲状腺容积呈逐年下降趋势。
Objective To analyze the change of thyroid volume in children aged 8 to 10 years in areas lacking iodine in Shandong Province. Methods The results of thyroid B-ultrasound examination of children with iodine deficiency disorders monitoring in the province from 1997 to 2005 were analyzed. The changes of thyroid volume in children aged 8-10 years were analyzed. Results The overall thyroid goiter rate declined year by year. The palpation rate of palpation was decreased from 22.3% in 1995 to 4.42% in 2005, while the B-ultrasound decreased from 7.75% in 1997 to 3.25% in 2005. The rate of goiter in children gradually increases with age, and thyroid volume in children increases with age. The thyroid volume of children of different age groups in iodine deficiency areas is shrinking year by year. Children with thyroid volume no significant change. Conclusions Thyroid volume in children aged 8 to 10 years in iodine deficiency area of Shandong Province shows a declining trend year by year.
