Health Assessment
Example Calculation
Geriatric BMI Example
Patient: 70-year-old Audrey
Height: 162 cm (1.62 m)
Weight: 70 kg
BMI Calculation: 70 ÷ (1.62)² = 70 ÷ 2.6244 = 26.7
Geriatric BMI Category: Normal weight (23-29.9)
BMI Formula
BMI = weight (kg) ÷ height (m)²
Geriatric BMI uses the same formula but different categories
Geriatric BMI Categories (65+)
Note: These ranges differ from standard BMI categories to reflect the healthier weight ranges for seniors.
Standard BMI Categories
Senior Health Tips
Regular physical activity helps maintain muscle mass and bone density
Balanced nutrition with adequate protein supports healthy aging
Focus on maintaining muscle mass rather than just weight loss
Regular health check-ups are essential for seniors
Slight weight gain with age can be protective for seniors
Understanding Geriatric BMI
Why is Geriatric BMI Different?
Standard BMI categories don't accurately reflect health risks for adults over 65. Research shows that slightly higher BMI ranges (23-29.9) are associated with better health outcomes and lower mortality risk in older adults.
Age-Related Body Changes
- •Decreased muscle mass (sarcopenia)
- •Increased fatty tissue proportion
- •Reduced bone density
- •Changes in metabolism and energy needs
Benefits of Higher BMI in Seniors
- Energy Reserves: Higher BMI provides energy stores for illness recovery
- Nutritional Buffer: Better nutritional status during health challenges
- Bone Protection: Weight-bearing effect helps maintain bone density
- Mortality Benefit: BMI 23-29.9 associated with lowest mortality in seniors
Research Foundation
Scientific Basis: Multiple studies show that BMI below 23 and above 33 are associated with increased mortality risk in adults over 65, leading to revised healthy weight guidelines for this population.
