采用配比病例对照研究方法 ,对经颅脑CT确诊的16 2例脑出血病人和 15 8例脑梗塞病人分别配以同等数量的对照作 1∶1配比分析 ,探讨中老年人脑出血和脑梗塞发病的危险因素。多因素条件logistic回归分析结果表明 ,脑出血的主要危险因素为高血压、短暂脑缺血发作 (TIA)、父母脑卒中病史及打鼾 ,相应的调整人群归因危险度 (PARs)分别为 0 70 0 4、0 186 2、0 135 7、0 2 0 2 0 ;4个因素综合的人群归因危险度(PAR)为 0 8318。脑梗塞的主要危险因素为高血压、TIA、习惯性饮酒和打鼾 ,相应的PARs分别为 0 7473、0 12 2 9、0 2 40 3、0 495 9;四因素综合的PAR为 0 9137,经常参加体育锻炼对脑梗塞具有保护作用 (OR为 0 30 )。
Using the matched case-control study method, 16 2 cerebral hemorrhage patients and 15 8 cerebral infarction patients diagnosed by brain CT were respectively allocated with the same number of controls for 1: 1 ratio analysis to explore the relationship between cerebral hemorrhage and Risk factors of cerebral infarction. Multivariate conditional logistic regression analysis showed that the main risk factors for cerebral hemorrhage were hypertension, transient ischemic attack (TIA), parental stroke history and snoring, and corresponding adjusted at-risk populations (PARs) were 0 70 0 4,0 186 2,0 135 7,0 2 0 2 0; The four-factor comprehensive population attributable risk (PAR) was 0 8318. The main risk factors for cerebral infarction were hypertension, TIA, habitual alcohol consumption and snoring, with corresponding PARs of 0 7473, 0 12 2 9, 0 2 40 3, 0 495 9, respectively, and those of the 4-factor combination of 0 9 13 7 Participation in physical exercise on cerebral infarction has a protective effect (OR was 0 30).
