1. What is BMI?

Body Mass Index (BMI) is a simple calculation using a person's height and weight. It provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

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

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: For women aged 65+ taking HRT, BMI is particularly important as it helps assess health risks associated with weight changes that may occur with hormone therapy.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For accuracy, measure height without shoes and weight in light clothing.

5. Frequently Asked Questions (FAQ)

Q1: Are BMI categories different for older women?
A: Yes, slightly higher BMI ranges may be acceptable for older adults as very low BMI can indicate health risks.

Q2: Does HRT affect BMI interpretation?
A: HRT may cause weight redistribution but doesn't fundamentally change BMI interpretation. Discuss any concerns with your doctor.

Q3: What is a healthy BMI range for women 65+?
A: Generally 23-30, but individual health factors should be considered. Consult your healthcare provider.

Q4: Are there limitations to BMI?
A: BMI doesn't distinguish between muscle and fat. Athletes or those with significant muscle mass may have higher BMI without excess fat.

Q5: Should waist circumference also be measured?
A: Yes, especially for older women, as waist measurement provides additional information about fat distribution.
