Most people are negative to their excess weight, but to overweight their children are not so critical. Parents, despite being overweight, continue to pamper their child with sweets, and as a result the child can not perform even basic physical activities. In families where there are material problems, on the contrary, there is a difficulty in providing the child with proper nutrition, which leads to a deficit in weight.
Usually, domestic pediatricians take averaged generally accepted data to determine weight values, although this method has not been used in the West for a long time, but the so-called BMI (body mass index of a child) is used, this is the indicator by which the weight norm is determined.
It is known that the body of children has the ability to easily fight overweight. Even if the child has extra pounds, it still remains mobile and active. Difficulties begin later, with the sexual maturation of the body. During this period, the development of the body is based on the construction of the foundation, which will be laid down in a person throughout life. If the child's organism is overloaded, then the consequences of this will necessarily manifest. To avoid problems in the future, every parent should know whether the child's weight corresponds to the norms.
The child and adolescent organism in the period of growing up has the property of continuous development, in contrast to the adult organism. Their bodies develop individually and therefore, at different developmental periods, one child may be different from another child, and the ratio of weight and height may also differ. Therefore, the method for determining the individual body weight for adults is only partially relevant here. In order to establish the indicator of the weight of the child, many studies were carried out, which resulted in the identification of standard indicators of the BMI of different ages of children. Thanks to these data, we can find out whether the weight of the child corresponds to the given age period.
The BMI of a child is considered as follows:
BMI = Weight / (Height in meters) 2
This method of calculation can be applied to adults, but the formula is applied for children from 2 to 20 years. Recently, changes have been made to this formula in the form of specifying coefficients, but they do not particularly affect the final indicator.
Take, for example, a two-year-old child with a height of 1 m and 20 cm with a weight of 17 kg. By the formula we get - BMI = 17: (1,2 2 ) = 11,8
But these coefficients give little information. It can be obtained from a specially developed BMI table, which is used by parents and pediatricians in the west.
Instructions
It is necessary to measure the height and mass of the child's body, then calculate the BMI using the formula. Mark on the chart such coordinate points as the child's BMI and his age. Label the point on the graph.
So, the age is 2 years, BMI = 11.8, respectively, on the axis of Age we mark point 2, and on the BMI axis the point is 11.8. Find the point of their intersection on the graph. This point indicates a reduced weight of the baby, because it falls into a strip of blue.
With the help of the graph, we can conclude on the extent to which the weight of the child is in comparison with height and age. This is the difference between the calculation of mass according to the BMI schedule from the usual methods adopted earlier, the calculus that indicate the correspondence or difference in the child's body weight from the norm, without relying on its growth.
Such measurements of weight and growth of the child's body should be done once in six months and marked on the graph, i.e. point of growth and the point of BMI. Next, we need to connect these points to a curve that shows the course of development of BMI and whether there is a tendency to excessive weight.
Next to the axis of BMI there are numbers - this is the percentage. It is necessary to set the point of the curve from your child's measurement points in comparison with the dashed points leading to the percentages. In the example described above, the point is below the 5% line. Consequently, less than 5% of children of this age and height have such a body mass. And if the point, for example, is near the line with a 20% index, it means that 20% of children of this age group and growth have such weight.
If the points are above the line with an index of 85%, then the child's weight is more than normal, and if above 95%, then the child is already obese.
