Food consumption analysis in spanish elderly based upon the mini nutritional assessment test

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Aging populations globally face increased risks of nutritional impairments.
• Understanding food consumption in the elderly is crucial for developing effective nutritional policies.
• The Mini Nutritional Assessment (MNA) is a key tool for evaluating nutritional status in older adults.

Purpose of the Study:

• To analyze specific food intake aspects using the MNA test in a Spanish elderly population.
• To identify dietary factors influencing nutritional status among older adults.
• To determine the predictive power of diet-related MNA questions on overall nutritional assessment.

Main Methods:

• Cross-sectional study involving 22,007 Spanish individuals aged 65+.
• Nutritional status assessed using the Mini Nutritional Assessment (MNA) test.
• Multiple regression analysis to evaluate the impact of diet-related MNA questions on the total MNA score.

Main Results:

• Significant differences in food choices observed between genders.
• Obese and non-obese individuals showed variations in fruit, vegetable, and fluid intake.
• Undernourished and non-undernourished subjects exhibited distinct food consumption patterns.
• Loss of appetite and feeding mode were the most influential factors on the MNA score.

Conclusions:

• Dietary factors predict 62.4% of the MNA classification in Spanish elderly.
• Age, gender, and BMI collectively account for 11.3% of the MNA score.
• Targeting dietary habits, especially appetite and feeding, can improve nutritional assessment and interventions in the elderly.
