Background and Purpose : The purpose of this case-control study was to show the relationship between risk factors(past medical history, BMI, WHR, smoking, drinking), warning signs(dyscinesia, sightless, dysarthria, sensory disorder, numbness, blephalospasm, facial spasm, tension) and the incidence of stroke in korean adults.
Methods :455 stroke patients were enrolled as the case group and 180 non-stroke patients as control group from Oct. 2005 to Feb. 2006. Patients were hospitalized within 2 weeks after the onset of stroke. Obesity were defined as BMI≥25㎏/m2, WHR≥0.9 in male and WHR≥0.8 in female. Risk factors and warning signs were obtained from personal interview. The analysis of the data was done by chi-square test, Fisher’s exact test and two-sample t-test.
Results : The percentage of current smokers(or current drinkers) of case group is higher significantly than that of control group. The past medical history of risk factors were found to be transient ischemic attack(p=0.0698), facial palsy(p=0.406l), hypertension(p＜0.0001), hyperlipidemia(p=0.l484), DM(p＜0.0001), ischemic heart disease(p=0.0093). migraine(p=0.0014) and hypochondria(p=0.2370). WHR≥0.9 in male had a 6.696 (3.711-12.082) odds ratio, WHR≥0.8 in female had a 1.567 (0.659-3.726) odds ratio. BMI≥25㎏/m2 had a 2.017(1.263-3.222). The dyscinesia and sensory disorder of warning signs were found to be statistical difference between case and control group.
Conclusions : According to the above results, it was found that smoking, drinking, BMI, WHR, hypertension, DM, ischemic heart disease, migraine affected to the incidence of stroke.
