舟山海岛居民甲状腺超声检查结果分析

目的了解舟山海岛居民甲状腺结节、甲状腺肿大及其他甲状腺疾病患病率。方法随机抽取舟山市2县区中6个居委会(村)3206名当地常住居民,采用探头频率7.0～10.0MHz的开立SSI-1000彩色超声诊断仪对调查对象开展甲状腺超声检查。结果本次调查发现甲状腺结节、甲状腺肿大及其他甲状腺疾病共1087人,总的异常率33.90%(1087/3206);甲状腺结节率、单发性甲状腺结节率分别为28.88%(926/3206)和19.00%(609/3206),与全省平均水平相比较差异有统计学显著性(χ2﹦47.20,P﹦0.000;χ2﹦95.10,P﹦0.000),多发性甲状腺结节率为9.89%(317/3206),与全省平均水平相比较差异无统计学显著性(χ2﹦0.056,P﹦0.812);城市居民甲状腺结节患病率明显高于农村(32.20%vs25.47%,X2﹦9.76,P﹦0.002);女性居民甲状腺结节患病率明显高于男性(31.24%vs24.31%,χ2﹦9.44,P﹦0.002);甲状腺肿大率、钙化病灶率、实质回声不均匀率、甲状腺腺瘤率分别为0.87%(28/3206)、2.15%(69/3206)、1.97%(63/3206)和0.03%(1/3206)。结论舟山市城乡居民整体甲状腺结节率、单发性甲状腺结节率明显高于全省平均水平,以女性、城市居民、41岁(中年)组、66岁以上(老年)组相对高发,且患病率随着年龄的增加而升高;甲状腺肿大、钙化、实质回声不均匀及甲状腺腺瘤等其他甲状腺疾病处于低发水平。

Analysis on thyroid ultrasonography results of residents in Zhoushan islands

Objective To measure the incidence rates of thyroid nodule,thyroid enlargement and other thyroid diseases of residents in Zhoushan islands.Method 3 206 local permanent residents in six communities(villages) of two districts were sampled randomly.Thyroid ultrasonography by Kaili SSI-1000 chromoscope ultrasonic diagnostic equipment with the probe’s frequency of 7.0~10.0MHz were conducted in all respondents.Result 1 087 cases with thyroid nodule,thyroid enlargement and other thyroid diseases were diagnosed with the total incidence rete of 33.90%(1087/3206).The incidence rates of thyroid nodule and sigle thyroid nodule were 28.88 %(926/3206) and 19.00 %(609/3206) respectively,the difference between which in Zhoushan and those of whole province average level had a statistical significance(χ2=47.20,P=0.000;χ2=95.10,P=0.000).The incidence rate of multiple thyroid nodule was 9.89 %(317/3206),the difference between which and that of whole province average level had no statistical significance(χ2=0.056,P=0.812).The incidence rate of thyroid nodule in urban residents was significantly higher than that in rural area(32.20% vs 25.47%,χ2=9.76,P=0.002).And that in female was significantly higher than that in male(31.24 % vs 24.31 %,χ2=9.44,P=0.002).The incidences of thyroid enlargement,calcified lesions,asymmetrical echo of thyroid parenchyma and thyroid adenoma were 0.87%(28/3 206),2.15%(69/3 206),1.97%(63/3 206) and 0.03%(1/3 206) respectively.Conclusion The levels of total thyroid nodule and single thyroid nodule incidence rates of residents in urban and rural area of Zhoushan city were significantly higher than average level in Zhejiang province.And those of female residents,urban residents,41-and above 66 years old group were relatively high.The incidence rate was increased along with the growth of age.The incidence rates of thyroid enlargement,calcified lesions,asymmetrical echo of thyroid parenchyma and thyroid adenoma were at low level.
