BODY MASS INDEX
BMI is used as a screening tool to identify possible weight issues for adults and children. For example, a person may have a high BMI. However, to determine if excess weight is a health risk, a healthcare provider would need to perform further assessments. These assessments might include skinfold thickness measurements, evaluations of diet, physical activity, family history, and other appropriate health screenings.
The following cutoff values are used to determine your health status that is whether you are underweight or above a normal desired weight.
- 18.5 or less: Low BMI (underweight)
- 18.5 to 24.9: Medium BMI (normal weight)
- 25 to 29.9: High BMI (overweight)
- 30 and above: Very-High BMI (obese)
Here is a formula to determine your BMI
Formula: weight (lb) / [height (in)]2 x 703
Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a conversion factor of 703.
Example: Weight = 150 lbs, Height = 5’5″ (65″)
Calculation: [150 ÷ (65)2] x 703 = 24.96
