The health of the child must be under the supervision of my mother always. And no matter how many years chadu- 2 years or 20! Because, as you know, the problem is easier to prevent than to cure. And the most striking fact conclusively - calculation of body mass index (BMI). This growth rate ratio to body weight at the right time can tell Mom, is there a tendency to obesity in a child or an urgent need to solve the problem of underweight.
Body Mass Index: a turn-based formula for calculating
To calculate BMI, you need to take 3 steps:
- Measure the child's height (in meters). For example, the growth of your baby - 1.25 m.
- then the resulting figure squaring. That is, 1,25h1,25 = 1.5625 m.
- We share the child's weight on the resulting figure. That is, with the weight of a child of 25 get the following formula: 25 / 1.5625 = 16.0.
Analysis of results
What to do with the resulting figure? Analyze the data with the help of graphics! Here is an example below:
In other words, if we take as a basis that our child 9 years old and he was a boy, then you should open the chart of BMI for boys. Further, on the lower axis find number 9 (child's age), on the left or right axis - figure 16.0 (a BMI of the child). We look at the intersection of lines extending from the obtained points.
And evaluate the results:
• red and green lines - ideal height-to-weight ratio;
• above the yellow field - a large bust of body weight;
• centile corridor (ie, the average value for the child's age) - 75% -85% - a little too much weight;
• centile corridor 50% -75% - norm, the weight ratio of the growth medium above;
• centile corridor 25% -50% - norm, the weight ratio of the growth medium below;
• centile corridor of 10% -25% - a small shortage of body weight;
• below the yellow field - a large shortage of body weight.
