Background and Purpose : To prevent ischemic cerebral infarction, it is very important to reduce risk factors which might cause stroke. However, the relationship of coffee consumption with ischemic cerebral infarction still remains unclear. The purpose of this study was to investigate the effects of coffee consumption on the risk of ischemic cerebral infarction in Koreans.
Methods : A case-control study was conducted from April 1, 2001 to July 31, 2004. Cases (n=435) of first incident ischemic cerebral infarction were enrolled and were mostly matched by age to stroke-free hospital controls (n=407). All subjects were interviewed, examined and had anthropometric measurements by using an organized questionnaire. The coffee consumption was classified by the average frequency of intake, being none, 1 cup/day, 2-4 cups/day, more than 5 cups/day. Odds ratios (ORs) of ischemic cerebral infarction were proved multivariate analysis after adjustment for demographic factors, diet factors, and vascular risk factors.
Results : When adjusted for sex, age, and other factors, coffee consumption and stroke do not have a significant association. ( cup/day OR=1.035, 95% CI=0.880-2.756; 2-4cups/day OR=1.452, 95% CI=0.864-2.440; 5 cups/day OR=1.557, 95% CI=0.705-3.435)
Conclusions : In this study, we conclude that coffee consumption is not an important risk factor of ischemic cerebral infarction in Koreans. Prospective and cohort study on the relation between coffee consumption and the possibility of inducing ischemic cerebral infarctions in Koreans will be required in the future.
