[Food and malnutrition in the elderly]

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Malnutrition significantly impacts the elderly population, with higher prevalence in institutionalized individuals (15-40%) compared to those at home (4-10%).
• The consequences of malnutrition in older adults are multifaceted and can be severe, affecting overall health and quality of life.

Purpose of the Study:

• To highlight the prevalence and risk factors of malnutrition in the elderly.
• To outline effective nutritional management strategies for elderly individuals experiencing malnutrition.

Main Methods:

• Review of risk factors including body mass index (BMI) below 21 and significant weight loss (5% in one month or 10% in six months).
• Discussion of treatment modalities, prioritizing oral nutritional interventions and considering enteral and parenteral nutrition based on severity and digestive function.

Main Results:

• Identified key indicators for malnutrition risk: BMI < 21 and unintentional weight loss.
• Established a treatment hierarchy: oral nutritional support as first-line, followed by enteral nutrition for severe cases with a functional digestive tract, and parenteral nutrition as a last resort.

Conclusions:

• Proactive identification of malnutrition risk factors in the elderly is crucial for timely and effective intervention.
• A stepwise approach to nutritional support, starting with oral methods and progressing to enteral or parenteral nutrition as needed, optimizes outcomes for malnourished elderly patients.
