Objectives: To examine the changes in and to identify determinants of health-related quality of life (HRQOL) during the first year after stroke.
Design: Prospective cohort study.
Setting: Regional university teaching hospital in China.
Participants: Chinese survivors of stroke (N=303). Patients who were previously physically handicapped were excluded.
Interventions: Not applicable.
Main outcome measures: Barthel Index, Lawton Instrumental Activities of Daily Living (IADL), Chinese Mini-Mental State Examination, Geriatric Depression Scale (GDS), and the abbreviated Hong Kong Chinese version of the World Health Organization Quality of Life measure domain scores at 3, 6, and 12 months after the stroke.
Results: A total of 268 (88%) subjects completed the study. HRQOL data were available in 247 (82%) subjects at 3 months. Between 3 and 12 months, there was no significant change in Barthel Index and IADL scores, but there was significant increase in GDS scores. On multivariate analysis and multilevel modeling, there was a small but significant decrease in social interaction and environment HRQOL domain scores with time. GDS score was negatively associated with all 4 domains of HRQOL, whereas the Barthel Index score was associated with physical and psychological HRQOL domains only. Female sex, nursing home residence, welfare assistance, pain in affected limbs, soft diet or tube feeding, and lack of physical exercise were associated with poorer HRQOL.
Conclusions: Environment and social interaction HRQOL may decrease after 1 year of stroke among Chinese stroke patients. Depression has a more generalized adverse effect on HRQOL than basic functional disabilities. Health care professionals should focus on treating depression; group exercises and self-help group activities may help in promoting socialization and reintegration into community life.
