Implication

Cross-sectional study reveals that behavioral symptoms and non-sedentary time drive quality of life in severe dementia, highlighting targets for long-term care interventions.

Key Points

To identify the clinical and behavioral factors influencing the quality of life among older adults with severe dementia residing in long-term care facilities.
Conducted a cross-sectional study of 81 older adults (70 female, mean age 89.41 ± 6.68 years) aged ≥ 65 years with severe dementia in long-term care facilities.
Assessed quality of life using the Chinese version of the Quality of Life in Late-Stage Dementia Scale (QUALID-C) alongside measures of behavioral symptoms, pain, cognition, self-care, and physical activity levels.
Behavioral problems and non-sedentary time significantly predicted overall quality of life in multiple regression analysis (adjusted R² = 0.346, p = 0.001).
Discomfort subscale scores were significantly associated with pain level, behavioral problems, non-sedentary time, daily activity involvement, and length of stay (adjusted R² = 0.362, p = 0.000).
Behavioral problems emerged as the sole significant factor associated with the comfort subscale in the regression model (adjusted R² = 0.256, p = 0.008).
