To determine the relationship between quality of life (QOL) and environmental factors of temperature, noise, and lighting in nursing home residents with severe dementia.
Cross-sectional, observational, analytical.
Eight public, long-term care nursing homes in the province of Girona, Spain.
Random sample of 160 nursing home residents with severe dementia.
Functional and cognitive impairment, pain, neuropsychiatric disturbances, and QOL were determined using standardized instruments. Temperature, noise, and lighting in bedrooms, dining rooms, and living rooms were measured in the morning and afternoon using a multifunction environment meter in a standardized manner.
Adjusted multivariate linear regression models demonstrated that environmental measures were independently associated with QOL and related factors. High temperature in the bedroom was associated with lower QOL (standardized β = 0.184), high noise levels in the living room were associated with low behavioral signs of social interactions (β = 0.196), and low lighting levels in the bedroom were associated with number of signs of negative affective mood (β = -0.135).
The QOL of nursing home residents with severe dementia was related to environmental factors such as temperature, noise, and lighting. The monitoring of these environmental factors may improve these individuals' QOL.
确定严重痴呆养老院居民生活质量（QOL）与温度、噪声和光照环境因素之间的关系。
横断面、观察性、分析性。
西班牙赫罗纳省 8 家公立长期护理养老院。
随机抽取的 160 名患有严重痴呆症的养老院居民。
使用标准化工具确定功能和认知障碍、疼痛、神经精神障碍和 QOL。使用多功能环境计以标准化方式在早晨和下午测量卧室、餐厅和客厅的温度、噪声和光照。
调整后的多元线性回归模型表明，环境测量与 QOL 和相关因素独立相关。卧室高温与 QOL 降低相关（标准化β=0.184），客厅噪声水平高与社交行为迹象减少相关（β=0.196），卧室光照水平低与负面情绪迹象数量增加相关（β=-0.135）。
严重痴呆养老院居民的生活质量与环境因素（如温度、噪声和光照）有关。这些环境因素的监测可能会提高这些人的生活质量。
