Body mass index calculation is an issue that comes up especially in obesity problems. The reference values ​​based on this calculation process are determined by the World Health Organization. The basis of the calculation process is based on dividing the weight of the person by the square of the height value, that is, the formula kg / m².

It should be noted that the results of these calculations are of great importance in the diagnosis of obesity and categorization of the obesity problem. We will discuss in detail all the frequently asked issues such as obesity test and height and weight index in children. However, first of all, let’s take a closer look at the values ​​that are accepted as normal, that is, the body mass index of the person.

What Should Be Your Body Mass Index?

In the calculation of body mass index, the evaluation of the person is made as follows:

  • Normal if body mass index is between 18 and 25
  • Light weight if body mass index is between 25 and 30
  • If the body mass index is over 30, obese

At this point, it is necessary to underline an important element. If a person’s body mass index is over 35, then warning bells start ringing. Because obesity can bring along dozens of different health problems. Nowadays, obesity is the main cause of an uncountable number of diseases. For this reason, it is necessary to take the obesity problem seriously and take the first step in order to start the necessary treatment as soon as possible.

What Does Body Mass Index Mean?

After calculating the body mass index of the person, different values ​​such as waist circumference can be taken into account. The value obtained is used to make various classifications such as underweight, normal, overweight, obese. Of course, since the reference values ​​determined by the World Health Organization are taken into consideration, the interpretation of the calculation result not only in our country but also in the whole world does not change. In a sense, we can say that the body mass index value is an expression used to determine whether the person is at a normal weight.

One of the first concepts that confronts people with weight problems is body mass index calculation. Because we can state that the answer to the questions such as whether the person is overweight and what level of obesity problem is given by this calculation. The purpose of this calculation is to determine whether the person is at a healthy weight. After the result of this calculation is taken into account, some measurements and evaluations may also need to be made.

It is possible to determine the most appropriate weight loss program by taking into account the metabolic rate, the body regions where fat cells are stored, the general health status of the person and similar evaluations. For example, not all individuals with obesity problems can benefit from treatment methods such as gastric sleeve surgery immediately. Especially those with severe obesity problems may need to fall within a certain weight range first. Here, the primary factor in making all these evaluations is the body mass index.

Height Weight Index in Children

First of all, we should mention that body mass index in children can vary according to both age and gender. This is true for young people as well as children. The high amount of fat in the body can invite diseases due to overweight as well as very serious health problems.

It is not just excess weight that spoils health. Just as the fat ratio is less than ideal, sudden extreme weakness can cause serious damage to health. We can state that height and weight follow-ups of children are performed by pediatricians and percentile curves are taken as a reference for evaluation. In case of any problems, pediatricians will make the necessary guidance.

How is Obesity Test and Calculation Done?

The “Body Mass Index – BMI (Body Mass Index-BMI) calculation” method is used in calculating the body mass index, which is also called obesity test or obesity calculation. We can give the following information for the evaluation of this calculation and calculation result:

BMI = weight of body in kg / square of height in meters

For a clearer understanding of the calculation process, we can give a simple example. Suppose a person weighs 100 kg and is 1.80 cm tall. In this case, the calculation is as follows:

8 x 1.8 = 3.24
100 / 3.24 = 30.8

In other words, the body mass index value of this person is 30.8. Therefore, this value is in the “obesity” classification according to the data of the World Health Organization.

Body Type is Important in Calculating Obesity!

As we have mentioned above, only the person’s body weight and height are taken into account in the calculation of body mass index. Different parameters such as the person’s body type, adipose tissue, muscle tissue are not included in this calculation. However, in order to obtain more detailed data on the obesity problem of the person, waist circumference measurement and detailed body analysis should also be done. It is very important to consider the measurement of metabolic rate.

We can explain this issue with a short example. If the measurement result of the waist circumference in men exceeds 94 cm, it is in the “risky” category, and if it is above 102 cm, it is in the “high risk” category. Let us state that if the waist circumference of women exceeds 80 cm, they are considered to be “at risk” and if they exceed 88 cm, they are considered in the “high risk” group. As a result, it should never be overlooked that the body type of the person and in which part of the body the fats are stored are important.

What Do Body Mass Index Results Mean?

Especially those who complain about the obesity problem may wonder what classification they are included in as a result of the body mass index calculations. We can explain the types of obesity and the results of BMI calculations in the simplest form as follows:

  • Under 8.5 kg / m2: Poor
  • 5 – 24.9 kg / m2: Normal weight
  • 25 – 30 kg / m2: Overweight
  • 30 – 35 kg / m2: Type 1 obese
  • 35 – 40 kg / m2: Type 2 obese

Those with 40 kg / m2 and above are considered to be severely obese or more known as “morbid obese” We can state that two different classifications are made for people who are evaluated in the morbid obesity category. These;

  • 50 kg / m2 and above: Super obese
  • 60 kg / m2 and above: Super super obese

Of course, these results are taken as the basis for determining the surgeries, treatments or diet lists to be applied to people with obesity problems. Therefore, it will be useful to underline that these calculations and classifications are of great importance.

What are Considered Outside of Body Mass Index?

Of course, the result of the body mass index calculation process is very important. However, at the same time, determining the region where fat is most stored in the body is an important data for treating obesity in the most appropriate way. At this point, we can also state that the way adipose tissue accumulates in the body is generally evaluated in two different classes, apple type and pear type.

In the apple type obesity problem, fat cells are mostly collected around the belly. In the pear type, more fat accumulation is observed in the hips and buttocks. Of course, fat accumulation around the belly is more dangerous in terms of the risk of cardiovascular diseases. You can write your questions on the subject in the comment section.
