上海市程桥社区老年人外周动脉疾病患病率的调查

Study on the prevalence of peripheral arterial disease in an urban population aged 60 years and over in Chengqiao community,Shanghai

目的调查上海市长宁区程桥社区60岁及以上人群下肢外周动脉疾病病的患病情况。方法采用便携式多普勒血流仪（8MHs）对程桥社区2360例60岁及以上人群进行踝臂指数的测量，以踝臂指数≤0．9定义为下肢外周动脉疾病，并对患病情况进行分析。结果下肢外周动脉疾病患病率为8．7％，其中男8．0％，女性9．3％；60～69岁组6．9％，其中男性7．0％、女性6．9％；70～79岁组9．4％，其中男性8．0％、女性10．8％；80-97岁组12．6％，其中男性12．2％、女性12．9％。随增龄下肢外周动脉疾病患病率逐渐增高（P〈0．05）。男女性别构成在各年龄组差异无统计学意义（P〉0．05）。有不同危险因素的患者中，下肢外周动脉疾病的患病率分别为：冠心病124例（60．5％）、缺血性脑卒中59例（28．8％）、糖尿病131例（63．9％）、高血压161例（78．5％）、吸烟48例（23．4％）、高脂血症136例（66．3％）。结论上海市程桥社区60岁以上老年人下肢外周动脉病患病率为8．7％，低于欧美等国家的水平。下肢外周动脉疾病患病率与性别无关，与增龄有关。

Objective To investigate the prevalence of peripheral arterial disease （PAD） in an urban population aged ≥60 years in Chengqiao community, Shanghai. Methods A total of 2360 residents （aged 60 years and over） were studied in Chengqiao community by the ankle-brachial index （ABI） measurement using portable Doppler ultrasound device. An ABI less than or equal to 0. 9 was considered to be indicator of significant PAD. The physical examination and ABI were collected and analyzed. Results （1）The prevalence of total PAD in individuals aged 60 years and over was 8. 7%, in which male and female PAD were found to be 8. 0% and 9.3% respectively. PAD prevalence was found to be 6.9%, 9.4% and 12.6% in population aged 60-, 70-and 80- years . PAD was more popular in older people. （2）A total of 205 patients had PAD, among them 124 （60.5 %） patients were found to have coronary heart disease （CDH） ; 59 （28. 8%）, ischaemic stroke （IS） ; 131 （63.9%）, diabetes mellitus （DM） ; 161（78. 5%）, hypertension（HP） ; 136（66.3%）, dyslipidemia. Conclusions The level of the prevalence of PAD in Chengqiao community was lower than in European and American countries . The prevalence of PAD is not associated with gender. PAD is highly prevalent among high-risk Chinese patients, and more popular in the elderly.
