Body Mass Index (BMI for short) is a way of evaluating someone's weight in relation to their height. The Body Mass Index is sometimes referred to as the Quetelet's index which is named after Belgian pioneer Lambert Adolphe Jacques Quetelet who made the system during the nineteenth century. A person's obese level or obesity severity is determined primarily by their BMI using one of the BMI formulas (BMI formulae). BMI can also determine other weight levels such as underweight, normal weight and overweight. BMI does not measure a person's actual body fat.
A prevalent formula used to calculate one's BMI and obesity severity is in the International System of Units, commonly referred to as SI units or metric. This is someone's weight in kilograms divided by their height in metres squared, shown as BMI = kg / m². The " ² " simply means that you're multiplying the number prior to it twice. For example 1.5m² would give you a figure of 2.25 since its simply 1.5 x 1.5.
The other formulas used to calculate obesity severity are based on the system of imperial units. The two BMI formulas I'm about to mention are similar to the formula above with a few twists.
The first one based on imperial units is calculated by using one's weight in pounds (lbs) multiplied by 703 (seven hundred and three) and then divided by their height in inches squared. This can be shown as BMI = (lbs x 703) / in². What's in the parenthesis is what should be worked out first and then divided by inches squared. Another way people calculate this is BMI = (lbs / in²) and then multiplying what they get by 703.
The second one based on imperial units is calculated by using one's weight in pounds (lbs) again but this time multiplied by 4.88 (four decimal eight eight) then divided by their height in feet squared. This can be shown as BMI = (lbs x 4.88) / ft². Another way people calculate this is BMI = (lbs / ft²) and multiplying what they get by 4.88.
From any of the three BMI formulas mentioned above, if the end result is 30 or more, the person being tested is obese and has an obese level associated with their BMI. A BMI ranging from 25 to 29.99 is classed as overweight. Under 18.5 BMI is classed as underweight. The optimal BMI for individuals is from 18.5 to 24.99, that is where you should be.
There are different classes that describe obesity severity based on one's BMI. Class 1 obesity is mildly obese and BMI ranges from 30 to 34.99. Class 2 obesity is moderately obese with the BMI ranging from 35 to 39.99. Class 3 is morbidly obese which is above 40 BMI. The higher the class of obesity severity, the more vulnerable you are to weight associated health problems and the more apparent and dangerous these become.
In determining obesity severity in children and adolescents, one of the BMI formulas previously mentioned is used but the result is then compared to what's normal for that particular kid's sex and age and is given a percentile. You can view sample charts provided by the US Center for Disease Control with percentile for boys at this link and for girls at this link. Under the 5th percentile means the kid is underweight. From the 85th to just under the 95th percentile means the child is overweight. Above the 95th percentile means the child is obese. Between the 5th and 85th percentile is the optimal level for children and adolescents.
