作者于1989年11月在意大利从年龄在41～80岁的68193人中随机抽取样本345人,按性别和年龄分组,通过B型超声检查进行流行病学研究以确定颈动脉病变发生率及危险因素。经SAS统计分析,颈动脉疾病患病率为39％,经性别和年龄校正后为31％(95％CI:27％～35％)。单因素分类变量分析:年龄61～70岁组与≤60岁组的差异比(OR)为3.2(P<0.0001),年龄>70岁与≤60岁组的OR为28.21(P<0.001),男与女的OR为1.32(P>0.05);糖尿病OR为4.08(P<0.001);高胆固醇血症OR为1.54(P<
In November 1989, a random sample of 345 people from 68,193 people aged 41-80 years in Italy were randomly divided into groups by sex and age. Epidemiological studies were conducted by type B ultrasound to determine the prevalence and risk of carotid artery disease factor. According to SAS statistics, the prevalence of carotid artery disease was 39%, adjusted for gender and age by 31% (95% CI: 27% -35%). Univariate categorical analysis showed that the odds ratio (OR) was 3.2 (P <0.0001) between the age group of 61-70 years and the group of ≤60 years old, OR was 28.21 (P <0.001) between the age group of> 70 years and the group of ≤60 years, The OR of male and female was 1.32 (P> 0.05). The OR of diabetes was 4.08 (P <0.001). The OR of hypercholesterolemia was 1.54 (P <
