To evaluate the association between clinical and socio-demographic status and health-related quality of life (HR-QoL) in stroke survivors age 40 and older in the Korean population.
The relationship between stroke and HR-QoL was investigated using data from the Korea National Health and Nutrition Examination Survey (KNHANES), conducted from 2007-2012. The total number of respondents was 24,050 and 757 stroke survivors were included. Specifically, we investigated factors associated with the lowering of HR-QoL in a group of Korean adult stroke patients age 40 and older after adjusting for socio-demographic factors, anthropometric measurements, and clinical comorbidities. Adjusted effects of covariates on EuroQol-visual analog scales (EQ-VAS) scores were estimated with a complex-samples general linear model and multivariate-adjusted odds ratios of the lowest quintile versus highest quintile of the EQ-VAS scores in the stroke group were estimated with a complex-samples logistic regression model.
Socio-demographic, anthropometric factors, and clinical comorbidities significantly differed between the stroke and non-stroke groups, except regarding gender and residential area. The EQ-VAS was significantly lower in the stroke than non-stroke group. Anxiety/depression problems significantly lowered EQ-VAS, as did low education level, smoking, mobility and usual activities problems. Also, aging in 1-year increments and cardiovascular disease had a significant effect on lower EQ-VAS in stroke survivors.
People with a stroke have significantly lower HR-QoL than healthy subjects. Therefore, managing depression, smoking, or cardiovascular disease and maintenance of physical function may be priority goals in improving HR-QoL after a stroke.
