What is BMI?
BMI is a metric used to know whether a person has a normal body weight based on their height. It’s a simple number that helps people classify themselves in different weight ranges, such as underweight, normal weight, overweight, or obese.
How to Calculate BMI
- BMI uses a simple arithmetic formula:
- Or, for people who use pounds and inches:
Example Calculation
- Assume that a person weighs 70 kg and has a height of 1.75 meters.
- This value is in the normal weight range.
BMI Categories
WHO classifies BMI as follows:
- Underweight: BMI less than 18.5
- Normal weight: BMI 18.5 – 24.9
- Overweight: BMI 25 – 29.9
- Obese: BMI 30 and above
Importance of BMI
BMI is an important measure of the potential risks associated with weight to health. Those with a high BMI may be at greater risk for the following conditions:
- Heart Disease
- Diabetes
- High Blood Pressure
- Stroke
- Joint Problems
On the other hand, underweight can also lead to the following:
- Nutritional Deficiencies
- Weakened Immune System
- Osteoporosis
Limitations of BMI
Though BMI is a useful screening tool, it has some limitations:
- It does not distinguish between fat and muscle: an athlete may have a higher BMI because of his muscle mass but is not necessarily overweight.
- Does not take into account the distribution of fat: this is very important in evaluating the risk for health.
- It is not applicable to all populations: BMI is not an accurate measure for children, pregnant women, or the elderly.
Alternative Measures for Assessing Health
For a more accurate health analysis, here are some alternatives to BMI:
- Waist-to-Hip Ratio: Measures fat distribution.
- Body Fat Percentage: Is a more precise measure of the amount of body fat.
- Waist-to-Height Ratio: A more precise measure of health risk due to cardiovascular diseases.
