OBJECTIVE: Recent studies have demonstrated gender differences in functional outcome after stroke. However, the underlying reasons for differences have been inconsistent. The present study examined whether gender differences in long-term functional outcomes exist among surviving patients with first-ever ischemic stroke and with individual subtypes of stroke. METHODS: A total of 997 patients (654 men, 343 women) were followed for 5 years after discharge. Patients were assigned to 4 subtypes of ischemic stroke (atherothrombotic, lacunar, cardioembolic and unclassified infarction). Functional outcomes were expressed as locomotor activity, assessed using a questionnaire delivered by mail 1 and 5 years after stroke. Locomotor function was classified into 5 categories according to the grade of disability. RESULTS: Women showed significantly worse locomotor function than men at both 1 and 5 years (p < 0.001 and p < 0.01, respectively). Furthermore, significant gender differences in functional outcome were observed in all subtypes of ischemic stroke at 1 and 5 years after stroke. Logistic regression analysis revealed that gender was a significant determinant for functional outcome at 1 and 5 years after stroke (p < 0.01 and p < 0.001, respectively). No significant gender difference was seen in the rate of stroke recurrence. Women also showed a worse survival ratio after stroke than men (p < 0.01). CONCLUSION: The present study demonstrated significantly worse functional outcomes for women than for men at 1 and 5 years after stroke. Gender differences in long-term functional outcomes by subtypes of ischemic stroke were also significant.
