The Epidemiologic Survey For Peripheral Arterial Occlusive Disease In Eldely On The Wanshoulu Area, Beijing

First PartThe Prevalence Study of Peripheral arterial Occlusive disease (PAOD) on the Wanshoulu area, BeijingAbstractObjectives: The Prevalence of Peripheral arterial Occlusive disease (PAOD) was estimeted in 20411 men and women, aged 60-95 years, on the Wanshoulu area, Beijing.Methods: A cross-sectional survey for PAOD, Two thousands one hundred twenty-four Subjects from 9 residental communities, aged 60-95 years, male 943, female 1183, means aged 68.54?.43 years, were randomly selected out of 20411 older residents within 94 residental communities on the Wanshoulu area, Beijing.There were three diagnostic criteria for PAOD in this study.First criterion:Intermittent Claudication(IC) was defined as a Rose questionnaire; Second criterion: PAOD was defined as an ankle-arm index(AAI)^0.9; Third criterion: symptomatic PAOD was defined as the combination of an AAI^0.85 with clinical symptom or sign for 1C.Results: The prevanlence of PAOD as the frist criterion was 12.19%, male 7.95%, female 15.58%, standardized 11.95%; The prevanlence of PAOD as the second criterion was 15.91%, male 11.77%, female 19.22%, standardized 15.67%; The prevanlence of PAOD as the third criterion was8.62%, male 5.83%, female 10.84%, standardized 8.64%.Conclusions: The prevanlance of PAOD in this study was similar to the prevanlences of the PAOD studies in the developed countries. The prevanlence in this study was increased with advanced age and the prevanlance was higher in female than in male .Second partThe Study on the Risk Factors of Peripheral Arterial Occlusive Disease on the Wanshoulu area, BeijingAbstractObjectives: To investigate the risk factors contributing to peripheral arterial occlusive disease on the Wanshoulu area, Beijing.Methods: In a cross-sectional survey for PAOD, Two thousands one hundred twenty-four Subjects from 9 residental communities, aged 68.54 + 5.43( 60-95 )years, male 943 and female 1183 were randomly selected out of 20411 older residents within 94 residental communities on the Wanshoulu area, Beijing. There were three diagnostic criteria for PAOD in this study.First criterion: intermittent claudication(IC) was defined as a Rose questionnaire; Second criterion: PAOD was defined as an ankle-arm index(AAI)^0.9; Third criterion: symptomatic PAOD was defined as the combination of an AAI^ 0.85 with clinical symptom or sign for 1C. The factors contributing to PAOD in this study( including: age, gender, smoking, passive smoking, drinking, sleeping, obesity, family diease history, hypertension history, hypertension course, diabetes history, diabetes course, coronary artery disease history, stroke history, chronic bronchitis history, central retina artery atherosclerosis grading, hypercholesterolaemia history, hypertriglyceridemiahistory, glucose, triglycerides, cholesterol, high densyty lipoprotein, low density lipoprotein, grain foods, animal protein foods, sea foods, plant protein foods, vegetable foods, fruit foods) were performed the logistic regression analysis by the three diagnosis criteria of PAOD in this study. Stepwise selection was also used in this multivariate regression analysis.Results: In the logistic regression analysis by the first criterion: the factors,such as age(P=0.001 RR=1.07),female gender(P=0.001 RR=2.33), hypertension history(P=0.013 RR=1.80), diabets course(P=0.001 RR=1.05), strok history(P=0.017 RR1.49), obesity(P=0.003 RR=1.79) and low density lipopotein(P=0.014 RR= 1.18) were independent risk factors contributing to PAOD in this study. In the logistic regression analysis by the second criterion: the factors, such as age (P=0.001 RR=1.06), female gender(P=0.001 RR=1.93), hypertension history (P=0.001 KR=1.48)and diabets course (P=0.001 RR=1.04) were independent risk factors contributing to PAOD in this study. In the logistic regression analysis by the third criterion: the factors, such as age (P=0.001 RR=1.09), female gender(P=0.001 RR=2.92), hypertension history(P=0.001 RR1.73), diabets course(P=0.001 RR=1.06), cholesterol(P=0.
