Prospective Study on Appetite Stimulation by Culinary Scents in the Elderly People

"Adult patients resident in Pavillon C of the Pierre Garraud Hospital, aged over 70, polypathological, with or without undernutrition.~The intervention involves the diffusion of culinary odors using diffusers in the unit's hallways, 20 minutes before lunch, from Monday to Friday, for a period of three weeks.~This experiment will be repeated over 18 weeks (6 cycles), alternating meals without olfactory stimulation (cycles 1, 3 and 5) and meals with stimulation (cycles 2, 4 and 6).~The 3-week rhythm corresponds to the menu cycle proposed by the Unité Centrale de Production Alimentaire (UCPA). Thus, the menu will be the same whether or not it is associated with the diffusion of culinary scents."
