Nowadays everyone wants to be slim and smart. Each one of us is talking about how to get normal weight. So here through Bio Mass Index, we will come to know that whether you are overweight, underweight or you have normal weight. For this purpose, we will discuss all the steps and techniques used in Bio Mass Index (BMI) through which you will find about the category of your weight.
WHAT IS BIO MASS INDEX?
Bio Mass Index is a value that can be found by dividing the person’s weight by the square of the person’s height. It is generally expressed in kg/m². Here kilogram for mass (weight) and m² is for height. The value of BMI is age-independent and same for both sexes. BMI does not gauge the fat directly but studies have shown that BMI is somewhat correlated with a direct measure of body fat obtained from skin fold thickness measurements.
HOW BMI IS INTERPRETED FOR ADULTS
For people of 20 years of age or older BMI is interpreted by using standard weight status categories. All these categories are similar for both sexes of all body types and all ages. We have given a detailed table of various weight categories.
You can find your weight status either using BMI calculator or by using BMI chart. See below a BMI chart is given and also a description that how you can find your weight status through BMI chart.
To get help from the below table, search your height on the left side of the chart. After this go across to the weight that is closest to your body weight. At the top of the table, you can see your BMI. Now you go straight to the bottom of the table to check in which category of weight your weight lies. Either obese, underweight or healthy weight.
We are discussing some examples here.
The above table shows us that if a woman’s height is 5ft and 4 in and her weight lies between 145 and 169 pounds, then she will be considered as overweight.
If a man’s height is 5 ft. 10 in. and his weight lies between 209 and 243 pounds then such man will be considered as obese.
These examples have been shown in cells with red borders in the above table.
CALCULATING MY BMI
You can also determine your own BMI. The actual formula to determine BMI uses metric system measurements: weight in kilograms (kg) divided by height in meters, squared (m²).
When using pounds and inches, the formula needs to be altered slightly. Multiply your weight in pounds by 703. Divide that by your height in inches, squared:
BMI = (weight in pounds * 703) ÷ (height in inches * height in inches)
For example, if you weigh 120 pounds and are 5 ft. 3 in. (63 in.) tall:
BMI = (120 x 703) ÷ (63 x 63) or 84,360 ÷ 3969 = 21.3
This is well within the healthy weight range.
BIO MASS INDEX IN CHILDREN AND TEENS
The same technique is used to measure the Bio Mass Index for kids and teens but the BMI for kids and teens is interpreted distinctively. The BMI of kids and teens is sex and age-specific because the amount of body fat changes with age and the amount of fat varies between girls and boys. That’s why for youngsters, BMI stages that define being normal weight or obese are based totally on the kid’s age and gender. For this purpose, the US Centers for Disease Control and Prevention (CDC) has structured age-and gender-specific growth charts. These charts are used to translate a BMI value into a percentile based on a child’s sex and age. The percentiles are then used to determine the unique weight groups. See the below table for various categories of weight in kids and teens.
Even in children being overweight can cause some serious health problem like cancer. So everyone of us should be aware of that.
