Background: Health-related quality of life (HRQoL) of stroke survivors can be described as an important and holistic index of stroke outcome. To enhance this all encompassing construct, information on its predictors at different phases of stroke is required.
Objective: This study sought to identify consistent determinants of HRQoL over the course of 1 year after stroke in Nigeria.
Methods: Information on socio-demographic, clinical, and functioning attributes of 55 consecutive individuals with first-ever stroke were obtained during acute admission and at 1, 3, 6, and 12 months post-stroke. Attributes of functioning namely, motor performance, functional activity, and participation were assessed using the Simplified Fugl-Meyer Assessment, the motor-Functional Independence Measure, and the London Handicap Scale, respectively. HRQoL was also assessed with the Health-Related Quality of Life in Stroke Patients-40 scale at 1, 3, 6, and 12 months. Attributes that were associated with HRQoL at these time points were identified using bivariate and multivariable regression analyses.
Results: Among the independent variables, concurrently assessed participation was the sole significant (P < 0.0001) determinant of HRQoL at 1, 3, and 6 months, respectively accounting for 70%, 64%, and 75% variance in HRQoL. At 12 months, participation (P < 0.0001), and functional activity (P < 0.05) accounted for 83% variance in HRQoL, with better functional activity and participation associated with better HRQoL.
Conclusion: The outcome of this study indicates that optimizing post-stroke functional activity and participation through proven and effective rehabilitation strategies may result in better HRQoL in stroke survivors.
