目的提供成年健康人群甲状腺结节的患病率。方法用高频彩超对健康成人行甲状腺普查。结果1349例健康成人中甲状腺结节的检出率为29%,各年龄组甲状腺结节的检出率有显著差异,明显递增;甲状腺结节在女性健康人群的检出率高于男性,其中女性为37%,男性为24%。检出最小结节为2mm×1.5mm,大多显示为低回声结节,80%以上为直径1.520mm的结节;;6例经手术病理证实为甲状腺癌,占受检人数的0.44%。结论甲状腺结节的发病率远较国内外文献报道的高,女性发病率远远高于男性;随着年龄增长甲状腺结节的检出率明显增加,甲状腺癌的检出率也远高于文献报道。提示在健康人群中进行甲状腺普查是必要的。
Objective To provide the prevalence of thyroid nodules in healthy adult populations. Methods The thyroid census was performed on healthy adults using high frequency ultrasound. Results The detection rate of thyroid nodules in 1349 healthy adults was 29%. There was a significant difference in the detection rate of thyroid nodules in all age groups. The detection rate of thyroid nodules was higher in women than in men. 37% of women and 24% of men. The smallest nodules detected were 2 mm × 1.5 mm, most of which showed hypoechoic nodules, more than 80% were nodules with a diameter of 1.520 mm; 6 cases were thyroid cancer confirmed by pathology, accounting for 0.44% of the examined population. Conclusion The incidence of thyroid nodules is much higher than that reported in domestic and international literature. The incidence of females is much higher than that of men. The detection rate of thyroid nodules increases with age, and the detection rate of thyroid cancer is much higher than that of literature. Reported. It is necessary to perform thyroid census in healthy people.
