1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. For senior women, BMI provides a general indicator of body fatness.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: The formula divides weight by the square of height to account for the relationship between height and body surface area.

3. Importance of BMI Calculation

Details: BMI is a simple screening tool for weight categories that may lead to health problems. For senior women, maintaining a healthy BMI can help prevent osteoporosis, heart disease, and diabetes.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For seniors, slightly higher BMI ranges (up to 27) may be considered healthy compared to younger adults.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI for senior women?
A: For women over 65, a BMI between 23-30 is often considered healthy, as slightly higher weight can protect against osteoporosis.

Q2: Does BMI account for muscle mass?
A: No, BMI doesn't distinguish between muscle and fat. Athletic seniors may have higher BMI without excess fat.

Q3: How accurate is BMI for seniors?
A: BMI may overestimate body fat in seniors with lost muscle mass and underestimate it in those with preserved muscle.

Q4: Should waist circumference be measured too?
A: Yes, waist measurement (>35 inches for women) better indicates abdominal fat and health risks.

Q5: How often should seniors check BMI?
A: Every 3-6 months, or when significant weight changes occur, to monitor health status.
