No association was found between alcohol intake and hemorrhagic stroke.An elevated risk of ischemic stroke was found for men who drank infrequently, that is,a few times a year or less often(RR,2.0;95%confidence interval[ CI],1.3 to 3.2),for those who were intoxicated now and then(RR,1.8;95%Ci, 1.1 to 2.8),and for those who reported"binge"drinking a few times in the year or less often(RR,1.6;95%CI,1.1 to 2.5).Among women only ex-drinkers had an elevated risk of dying of ischemic stroke(RR,3.3;95%CI,1.5 to 7.2). The risk was reduced for women who had an estimated average consumption of 0 to 5 g pure alcohol per day(RR,0.6;95%CI,0.5 to 0.8);for those who did not drink every day(RR,0.7;95%CI,0.5 to 0.9);and for those who never"went on a binge"(RR,0.6;95%CI,0.5 to 0.8)or became intoxicated(RR,0.7;95%CI,0.5 to 0.9).Drinking habits were associated only with deaths from ischemic stroke,and the risk patterns were different for men and women.In analyses, ex-drinkers should not be included with lifelong abstainers,since the former tend to run high health risks. |
