为寻找蛛网膜下腔出血(SAH)的危险因素,作者对动脉瘤引起之 SAH 患者169例,与性别、年龄、种族及婚姻状态基本匹配,但教育程度略高的298例对照组作对比分析。患者资料由本人或亲友(53%为配偶,平均相处298天)提供者各占一半。用条件逻辑回归分析,吸烟>20支/日者,其 SAH危险度机率为11.1(95%可信限为5.0～24.9),<20支/日者为4.1(2.3～7.3),已戒烟10年以上者为1.8(1.0～3.2),示已无危险度差异。吸烟3h 之危险度最高,为7.0(3.7～13.1)。少量饮酒(<1次/日)机率为0.7(0.4～1.1),过量饮酒(>2次/日)为3.8(1.7～8.4)。用兴奋剂1周内危险度最高,为
To search for the risk factors for subarachnoid hemorrhage (SAH), 169 patients with SAH caused by aneurysms were compared with 298 controls who were slightly more educated than those who were sexually matched, age, ethnicity and marital status . Patient information is provided by each of my relatives or relatives (53% of spouses, on average 298 days) providers. Logistic regression analysis showed that the odds of SAH risk were 11.1 (95% confidence interval, 5.0 ~ 24.9) and 4.1 (2.3 ~ 7.3) for those with 20 cigarettes per day when smoking> 20 cigarettes per day. 1.8 years (1.0 ~ 3.2), showing no difference in risk. The highest risk of smoking 3h, 7.0 (3.7 ~ 13.1). The odds of having a small amount of alcohol consumption (<1 time per day) were 0.7 (0.4-1.1) and excess drinking (> 2 times / day) was 3.8 (1.7- 8.4). The highest risk for stimulants was 1 week
