Relationships Between Nutrition Risk and Frailty in Candidates for Lung Transplant.

Area of Science:

• Transplant Surgery
• Gerontology
• Nutritional Science

Background:

• Lung transplant candidates require optimization for better clinical outcomes.
• Frailty is a modifiable factor that may be influenced by nutritional status.
• Understanding the link between nutrition and frailty is crucial for pre-transplant care.

Purpose of the Study:

• To evaluate the association between nutrition risk and frailty in adult lung transplant candidates.
• To determine if poor nutrition contributes to physical and multidimensional frailty.
• To inform potential interventions for improving transplant eligibility.

Main Methods:

• Secondary analysis of data from 62 lung transplant candidates.
• Nutrition risk assessed using the Seniors in the Community: Risk Evaluation for Eating and Nutrition (SCREEN-14) questionnaire.
• Frailty measured by the Fried frailty index (FFI) for physical frailty and cumulative deficits frailty index (CDFI) for multidimensional frailty.

Main Results:

• A high prevalence of nutrition risk (83.9%) was observed in candidates.
• Higher nutrition risk was significantly associated with increased physical frailty (FFI).
• Candidates with high nutrition risk were more likely to be pre-frail or frail (92.3%) compared to those at low risk (60.0%).

Conclusions:

• Poor nutrition is prevalent and significantly associated with physical frailty in lung transplant candidates.
• Identifying and intervening in nutrition risk may be a key strategy to reduce frailty.
• Further research is needed to explore effective nutrition interventions in this population.
