背景和目的：长期护理中的严重阿尔茨海默病（AD）患者对比敏感度不足，食物和液体摄入量不足。本研究探讨了对比操作如何影响这些摄入水平。方法：参与者是 9 名患有晚期 AD 的男性。自变量是膳食类型（午餐和晚餐）和状况（基线、干预和干预后）。因变量是食物量（克）和液体量（盎司）。每天两餐收集数据，持续 30 天（每种情况 10 天）。白色餐具用于基线和干预后条件，高对比度红色餐具用于干预条件。在一年后的后续研究中，检查了其他对比度条件（高对比度蓝色、低对比度红色和低对比度蓝色）。结果：与基线（白色）条件相比，高对比度干预（红色）条件下食物的平均百分比增加为 25%，液体的平均百分比增加为 84%，9 名参与者中有 8 名表现出摄入量增加。在后续研究中，高对比度干预（蓝色）导致食物和液体摄入量显着增加；结论：简单的环境操作，例如对比度增强，可以显着增加体弱的 AD 痴呆患者的食物和液体摄入量。 (C) 2003 Elsevier Ltd. 保留所有权利。
Background & aims: Patients with severe Alzheimer's disease (AD) in long-term care have deficient contrast sensitivity and poor food and liquid intake. The present study examined how contrast manipulations affect these intake levels.Methods: Participants were nine men with advanced AD. Independent variables were meal type (lunch and supper) and condition (baseline, intervention, and post-intervention). Dependent variables were amount of food (grams) and liquid (ounces). Data were collected for 30 days (10 days per condition) for two meals per day. White tableware was used for the baseline and post-intervention conditions, and high-contrast red tableware for the intervention condition. In a follow-up study 1 year later, other contrast conditions were examined (high-contrast blue, low-contrast red and low-contrast blue).Results: Mean percent increase was 25% for food and 84% for liquid for the high-contrast intervention (red) versus baseline (white) condition, with 8 of 9 participants exhibiting increased intake. In the follow-up study, the high-contrast intervention (blue) resulted in significant increases in food and liquid intake; the low-contrast red and low-contrast blue interventions were ineffectual.Conclusions: Simple environmental manipulations, such as contrast enhancement, can significantly increase food and liquid intake in frail demented patients with AD.
