无锡地区人群甲状腺结节流行状况调查

目的研究无锡地区人群中甲状腺结节的患病情况。方法2005年5月至8月采用分层随机整体抽样方法,抽取无锡地区16岁以上常住居民807人,进行甲状腺B超和血清促甲状腺素检测。结果完成调查750人。调查人群中甲状腺结节患病率为22.53%,女性患病率显著高于男性(27.10%对16.82%),且男女患病率都随年龄增长而增加。男性和女性结节大小和数量构成比及结节体积比较差异均无统计学意义。有结节组和超声正常组甲状腺功能差异无统计学意义。女性群体中,有结节组甲状腺体积虽较超声正常组稍大,但差异无统计学意义。结论无锡地区人群中甲状腺结节发病率较高,应积极采用超声检查和甲状腺细针穿刺,早期发现和干预甲状腺结节。

An epidemiologic study of thyroid nodules among population in Wuxi of Jiangsu province

Objective To investigate the prevalence rate and epidemiologic characteristics of thyroid nodules among population in Wuxi.Methods A stratified cluster sampling technique was conducted to select 750 permanent inhabitants aged more than 16 years old in Wuxi of Jiangsu.B-ultrasonography of thyroid and serum thyrotropic-stimulating hormone(TSH)detection were carried out.Results The prevalence rate of thyroid nodules was 22.53% in the studied population.Thyroid nodules were significantly more prevalent in female than in male(27.10% vs 16.82%),and positive rate of thyroid nodules increased with age both in males and females.Regarding the proportion of thyroid size and amount,as well as thyroid nodule volume,there was no significant difference between male and female.There was also no significant difference in serum TSH and thyroid volume between groups with and without thyroid nodules both in men and women.Conclusion This epidemiologic study of thyroid nodules in Wuxi shows that thyroid nodules are highly prevalent.Ultrasonography and thyroid fine-needle aspiration biopsy are essential to detecting thyroid nodule and distinguishing the malignant ones,thereby early detection and intervention could be possible.
