What this trial studies

This observational study investigates the effects of culinary scents on appetite stimulation among elderly patients hospitalized in long-term care units. It aims to address the issue of undernutrition, which significantly impacts the health and quality of life of elderly individuals. By exposing participants to food odors prior to meals, the study seeks to enhance their eating experience and potentially increase food intake. The research is based on previous findings that suggest olfactory deficits contribute to reduced appetite in the elderly.

Who should consider this trial

Good fit: Ideal candidates are elderly individuals over 70 years old, residing in long-term care units who can eat orally and are autonomous in their eating habits.

Not a fit: Patients receiving parenteral or enteral nutrition or those in end-of-life care may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve appetite and nutritional intake among elderly patients, enhancing their overall health and well-being.

How similar studies have performed: Previous studies have shown promising results in using food odors to stimulate appetite in similar populations, indicating potential for success in this approach.
