目的了解中老年人群甲状腺结节的发病情况。方法对938例既往无甲状腺疾病史的离退休职工进行高分辨率甲状腺B超检查。结果本组资料甲状腺结节检出率男女分别为37.16%和45.70%,其中女性结节的发生率随年龄增长而显著升高(P<0.05);<1.0cm的微小结节占多数,男女分别为67.81%及64.08%;随着年龄的增长多发结节的比例上升,男性>70岁的多发结节占57.14%,显著高于<70岁人群(P<0.05)。结论 我国中老年人群甲状腺结节的发病率高,应重视甲状腺结节的早期诊断和早期治疗。
Objective To understand the incidence of thyroid nodules in middle-aged and elderly people. Methods Retrospective workers with 938 past history of thyroid disease were examined by high-resolution thyroid ultrasound. Results The detection rate of thyroid nodules in this group was 37.16% and 45.70% respectively, and the incidence of female nodules was significantly increased with age (P <0.05). Minimal nodules <1.0cm accounted for the majority of male and female 67.81% and 64.08% respectively. With the increase of age, the proportion of multiple nodules increased, and the multiple nodules aged> 70 years accounted for 57.14%, significantly higher than those of <70 years old (P <0.05). Conclusion The incidence of thyroid nodules is high in middle-aged and elderly people in our country. Early diagnosis and early treatment of thyroid nodules should be emphasized.
