摘　　要：目的研究老年人群中甲状腺结节的发病情况,了解结节特征及其与甲状腺功能的关系。方法对150例65岁以上老年人行甲状腺B超检查,同时测定甲状腺功能(T3、T4、TSH)。结果 150例老年人中,检出甲状腺结节62例,检出率为41.3%。其中65～70岁检出28例,占检出者45.2%;70岁以上检出34例,占检出者54.8%。70岁以上组检出率明显高于65～70岁组(P<0.05)。女性检出结节30例,检出率44.8%;男性检出结节32例,检出率38.6%,女性甲状腺结节检出率明显高于男性(P<0.05)。检出结节以多发(59.8%)、直径≤1.0cm的小结节(67.3%)为主。20例患者手术后病理证实:12例为甲状腺腺瘤、7例为甲状腺囊肿、1例为甲状腺乳头状癌。结节组与未检出结节组相比较,甲状腺功能测定差异无统计学意义(P>0.05)。结论老年人甲状腺结节发病率高,随年龄增长发病率增加,女性发病率高于男性。甲状腺结节不引起严重的甲状腺功能异常,应重视老年人甲状腺结节的早期诊断及治疗。Objective To study the prevalence of thyroid nodules in the elderly,and to evaluate the relationship between the features of nodules and the thyroid gland function.Methods A total of 150 patients aged over sixty-five years were randomly selected for the study.All patients had ultrasound examination and thyroid gland function testing（T3,T4,TSH）.Results Thyroid nodules were detected in 41.3%（62/150） of the elderly.The detection rate of thyroid nodules was significantly higher in the elderly over 70 years（54.8%,34/62） than in the elderly aged 65-70 years（45.2%,28/62）（P0.05）,and higher in females（44.8%） than in males（38.6%）（P0.05）.The majority of nodules were multinodular（59.8%） with diameter less than 1cm for most nodules.Twenty cases of thyroid nodules were diagnosed by pathology as adenoma（12）,thyroid cyst（7） and thyroid carcinoma（1）,respectively.There was no significantly difference in thyroid gland function between elderly population with nodules and without nodules.Conclusion The prevalence of thyroid nodules is high and increased with age in the elderly.The early diagnosis and treatment of thyroid nodules are required for the elderly.
