Nutritional assessment of institutionalized elderly

Area of Science:

• Gerontology
• Nutritional Science
• Public Health

Background:

• Nutritional status is critical for elderly health.
• Institutionalized elderly populations often face unique nutritional challenges.
• Establishing local nutritional profiles is essential for targeted interventions.

Purpose of the Study:

• To determine the nutritional profile of elderly individuals residing in a long-stay institution.
• To identify common nutritional diagnoses within this demographic.
• To assess the applicability of international nutritional standards in a Brazilian context.

Main Methods:

• A quantitative field study was conducted in a long-stay institution in Sao Paulo, Brazil.
• Nutritional diagnosis involved analyzing data from patient files, including anthropometric measurements (BMI, circumferences, skinfolds, muscle area, handgrip strength) and biochemical tests.
• Data were analyzed using descriptive statistics, stratified by gender and age, with statistical significance set at p<0.05.

Main Results:

• The study included 102 elderly individuals, with 84 being female.
• Excess weight was prevalent in men (61%), with some showing signs of protein depletion and potential sarcopenic obesity.
• While all women were initially considered healthy, 27% exhibited evident protein depletion.

Conclusions:

• Further anthropometric research is needed to establish local reference standards for gender and age-specific nutritional profiles.
• Variations between populations and methodological differences limit the reliable use of international nutritional standards for diagnosis.
• Developing region-specific nutritional guidelines is crucial for accurate assessment and intervention in institutionalized elderly populations.
