Understanding BMI
What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The BMI formula divides an adult's weight in kilograms by their height in meters squared.
Formula: BMI = weight (kg) / height (m)²
How is BMI Used?
BMI is used as a screening tool to identify possible weight problems in adults. However, BMI is not a diagnostic tool and should be used alongside other health assessments.
Healthcare providers use BMI along with other factors to assess health risks and determine appropriate interventions.
BMI Limitations
BMI May Overestimate Body Fat In:
- • Athletes and people with muscular builds
- • People with large bone structures
- • Certain ethnic groups with different body compositions
BMI May Underestimate Body Fat In:
- • Elderly people who have lost muscle mass
- • People with low muscle mass
- • Certain medical conditions affecting body composition
