This case study, in a Veterans Affairs Alzheimer's unit, was conducted to evaluate noise and lighting conditions at mealtimes and to assess the food intake of ambulatory dementia residents. The case study compared the noise, lighting, and nutritional intake of 16 Alzheimer's residents eating the same cycle menu in the extended-care (EC) dining room and the Alzheimer's unit (AU) dining room five weeks later. Noise was significantly lower in the EC (p. 02). Lighting was significantly higher in the EC (p. 001). Intake of calories and protein was slightly higher, with some days significantly higher, in the AU. Total five-day fluid intake at breakfast was significantly higher in the AU (p. 02). Although residents' total food and fluid intake was higher in the AU, the project identified a need to decrease noise and increase lighting in the AU. Lighting enhancement and noise reduction may further improve intake, which, in turn, may promote improved nutritional status.

Key Words: Alzheimer's disease • dining room environment • extended-care unit • lighting • noise • nutritionalintake • Alzheimer's unit
