BACKGROUND AND PURPOSE: There is limited information on the influence of ethnicity on functional outcome after stroke. We examined functional outcomes among European New Zealanders, Māori, Pacific, and Asian people 6 months after stroke in a population-based context. METHODS: This was a prospective incidence and 6-month outcomes study of all new stroke patients (excluding subarachnoid hemorrhage) that occurred over 1 year in a defined geographical area in Auckland, New Zealand, during 2002 to 2003. Ethnicity was self-defined. Outcome measures included the Frenchay Activities Index, 36-item Short Form questionnaire, independence, death, composite of death and dependence, and living situation. RESULTS: Functional measures were available in 1127 patients 6 months after stroke. Frenchay Activities Index scores were associated with ethnicity on both univariable and multivariable analysis, with Asian and Pacific people having worse scores. Physical Component Summary score of the 36-item Short Form was associated with ethnicity on univariable (scores for Pacific, Māori, and Asian people were higher than those for Europeans) but not multivariable analysis. Asian people were less likely to be dead compared to Europeans, and Pacific people were more likely to be dependent on others for help than Europeans. Pacific people were more likely to be dead or dependent than Europeans. Asian and Pacific people were more likely to be living at home than Europeans. CONCLUSIONS: Ethnicity was associated independently with functional outcomes. The association was attenuated when adjusted for stroke severity and other covariates. The direction of the relationship was not consistent between measures for individual ethnic groups.
