BMI Formula:
| From: | To: |
BMI (Body Mass Index) is a simple index of weight-for-height that is commonly used to classify underweight, normal weight, overweight and obesity in adults. It is calculated by dividing weight in kilograms by height in meters squared.
The calculator uses the BMI formula:
Where:
Explanation: The formula provides a simple numeric measure of a person's thickness or thinness, allowing health professionals to discuss weight problems objectively with their patients.
Details: BMI is an important screening tool for weight categories that may lead to health problems, but it is not a diagnostic tool. For women over 60, maintaining a healthy BMI is particularly important for reducing risks of osteoporosis, heart disease, and diabetes.
Tips: Enter weight in kilograms and height in meters. All values must be valid (weight > 0, height > 0). For women over 60, the same BMI categories apply but should be interpreted with consideration of age-related body composition changes.
Q1: Are BMI categories different for older women?
A: The standard categories apply, but interpretation should consider that older adults often have more body fat and less muscle mass at a given BMI compared to younger adults.
Q2: What is a healthy BMI for women over 60?
A: The same range applies (18.5-24.9), but some studies suggest a slightly higher BMI (up to 27) may be protective in older adults.
Q3: Does BMI account for muscle mass?
A: No, BMI doesn't distinguish between muscle and fat. A muscular person may have a high BMI without excess fat.
Q4: Should waist circumference be considered too?
A: Yes, especially for older women, as abdominal fat is a greater health risk than fat stored elsewhere.
Q5: How often should older women check their BMI?
A: Periodic checks (every 6-12 months) are recommended, along with other health assessments.
