From: | To: |
BMI (Body Mass Index) is a simple calculation using a person's height and weight to screen for weight categories that may lead to health problems. For seniors over 65, the healthy BMI range is slightly higher than for younger adults.
The calculator uses the standard BMI formula:
Where:
Explanation: The formula divides weight by the square of height to account for the relationship between body size and mass.
Details: For older women, a slightly higher BMI (23-29.9) is often associated with better health outcomes than in younger populations, as it may protect against osteoporosis and frailty.
Tips: Enter weight in kilograms and height in meters. For seniors, measurements should be taken in the morning after bathroom use for consistency.
Q1: Why is the healthy BMI range different for seniors?
A: Older adults naturally have more body fat and less muscle mass. A slightly higher BMI helps protect against malnutrition and frailty.
Q2: What are the BMI categories for seniors?
A: For women over 65: Underweight (<23), Normal (23-29.9), Overweight (30-34.9), Obese (35-39.9), Severely Obese (≥40).
Q3: Are there limitations to BMI for seniors?
A: BMI doesn't distinguish between muscle and fat, and may be less accurate for very short or very tall individuals.
Q4: Should waist circumference also be measured?
A: Yes, waist measurement (>35 inches for women) helps assess abdominal fat which carries additional health risks.
Q5: How often should seniors check their BMI?
A: Every 3-6 months, or when there's significant weight change (>5% of body weight).
