1. What is BMI?

Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to adult women over 65. For older adults, BMI ranges may be interpreted differently to account for age-related changes in body composition.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

Explanation: BMI provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems objectively.

3. Importance of BMI for Older Women

Details: For women over 65, BMI is an important health indicator but should be interpreted with consideration of age-related changes in muscle mass, bone density, and body composition.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0). For older women, BMI between 23-30 may be optimal for health.

5. Frequently Asked Questions (FAQ)

Q1: Are BMI ranges different for older women?
A: Yes, slightly higher BMI ranges (23-30) may be associated with better health outcomes in older women compared to younger adults.

Q2: What are the limitations of BMI for older women?
A: BMI doesn't distinguish between muscle and fat, and may underestimate obesity in older women who have lost muscle mass.

Q3: Should waist circumference be measured too?
A: Yes, waist measurement provides additional information about abdominal fat, which is particularly important for health risks.

Q4: How often should older women check their BMI?
A: Annual checks are reasonable unless there are significant weight changes or health concerns.

Q5: What's a healthy BMI for a 70-year-old woman?
A: Many experts recommend 25-27 as optimal, but individual health factors should be considered.
