In France, in most nursing homes, the composition of menus, the time and the place at which meals are served, the choice of one's place at the table are imposed on residents. Yet, the act of eating cannot be restricted to nutritional and sensory aspects alone. It also includes a psycho-affective dimension, which relates to the context in which the meal is served. We tested the impact of four contextual factors, considered individually, on food intake and meal pleasure in elderly people living in nursing homes: the way the main course was named on the menu, the size and the variety of portions of vegetables served to residents, the presence or not of condiments in the middle of the table and the presence or not of elements to modify the surroundings such as a decorative object on the table or background music. Twelve experimental meals were served to 42 nursing home residents. For each factor, we compared a control condition with two experimental conditions. Our study showed that changing a single contextual element of the meal in nursing homes could be sufficient to improve residents' satisfaction with their meals and increase the quantities of meat or vegetables consumed, as long as this factor had a direct impact on what was going to be consumed (increased variety on the plate, condiments on the table). Factors affecting the context of the meal (names of dishes, decor) proved to be ineffective. Given the budgetary constraints faced by nursing homes, this study proposes interesting and inexpensive ideas to increase satisfaction with meals and food intake in elderly people who are dependent on others for their meals.
在法国,大多数养老院都规定了菜单的组成、用餐时间和地点,以及居民在餐桌上的座位选择。然而,进食行为不能仅仅局限于营养和感官方面。它还包括心理情感层面,与用餐的环境有关。我们测试了四个被认为是独立的环境因素对养老院中老年人食物摄入量和用餐愉悦感的影响:菜单上主菜的命名方式、提供给居民的蔬菜份量的大小和种类、餐桌中间是否有调味料以及是否有环境元素来改变周围环境,例如桌上的装饰物或背景音乐。十二顿实验餐被提供给 42 位养老院居民。对于每个因素,我们将控制条件与两个实验条件进行了比较。我们的研究表明,只要这一因素直接影响到要食用的食物(盘子里的食物种类更多、桌上有调味料),改变养老院用餐的单一环境因素就足以提高居民对用餐的满意度,并增加肉类或蔬菜的摄入量。影响用餐环境的因素(菜名、装饰)证明是无效的。考虑到养老院面临的预算限制,这项研究提出了一些有趣且经济实惠的想法,以提高依赖他人用餐的老年人对用餐和食物摄入的满意度。
