浙江省舟山渔区外周动脉病患病率调查

Prevalence of peripheral arterial disease and its risk factors in Zhoushan fishery area in Zhejiang Province

目的调查我国渔区自然人群中的外周动脉病患病情况。方法2004年夏季(休渔期)在舟山渔区10个渔业自然村用整群抽样的方法抽取≥35岁的渔民及其家属2668人进行1次横断面调查。全部受检对象采用便携式多普勒血流仪(8MHz)进行测量,以踝臂血压指数(AAI)<0.9定为外周动脉病。并作空腹血糖及口服葡萄糖耐量试验检测正常糖耐量、糖耐量异常及糖尿病患者。结果外周动脉病总患病率为2.1%,在糖耐量正常、糖耐量异常及糖尿病者分别为2.1%、2.9%及6.3%,其患病率随年龄增长而增加,<50岁者仅2例。结论在舟山渔区人群中外周动脉病的总患病率较低。

Objective To study the prevalence of peripheral arterial disease（PAD）. Methods Totally 2668 fishermen and their families above 35 years old were recruited in a cross sectional study of randomly cluster sampling in 10 villages of Zhoushan fishery area, one of the biggest four fishery in the world, in Summer. All the cases underwent the ankle arm index （AAI） measurement using portable doppler ultrasound device. An AAI less than or equal to 0.9 was considered to be indicative of significant PAD. Fasting plasma glocose and oral glucose tolerance test（OGTT）were also examined to distinguish normal glucose tolerance（NGT）, imparied glucose tolerance（IGT）and diabetes melitus （DM）. Results The prevalence of PAD of 2668 cases was 2. 1%. PAD prevalence was found to be 2.1%, 2.9%, and 6.3% in patients with NGT, IGT, and DM respectively. It was seldom seen in people under 50 years old and the PAD was more popular in older people. Conclusions The prevalence of peripheral arterial discase of the general people in Zhoushan fishery area is lower.
