What is a Persentile (Growth Curve)? How is it Interpreted?

What is percentile?

The word percentile will enter her life with the birth of her baby. This percentile word you’ll hear for the first time simply means growth curve, to say the least. This growth curve shows the physical values ​​that your child should have over the years.

In other words, you can understand whether the physical development of your baby is progressing in a healthy way, according to the age and gender, by following the percentile curve types. This way, you can detect early whether your child has a developmental problem or illness. This is the percentile curves you’ll see in the table based on the average of Turkey.

So what is the value of physical development? The percentile table includes baby height, weight and head circumference values. Because these 3 features are among the most important elements of health criteria in infant development.

In this part, we need to touch upon a subject. Parents are generally more curious about their height and weight percentile values. However, head circumference percentile values ​​are much more important, especially in infancy.

How to read the perspective table?

You will see various numbers in the baby percentile chart.

It is absolutely necessary to consult a pediatrician for the diagnosis and treatment of growth retardation.

10-25 percentile is the low percentile value. It should be evaluated and followed up with a pediatrician.

25-75 percentile is normal value. Development of the baby is considered normal compared to other babies of the same age and sex. With balanced and proper nutrition, percentile values ​​should be calculated and followed at 3-month intervals.

The 75-90 percentile is a high value. More weight, taller, bigger than it should be. means head circumference. With a more balanced nutrition program and doctor’s examination, it should be ensured that the normal values ​​band is reached.

90-100 percentile is the highest value. In this case, the development of the child is much higher than normal. There may be problems such as obesity and gigantism. It should definitely be checked with the pediatrician.

When examining the development of the child, the 50th percentile, that is the mean value, is generally taken as a basis, but between 10th and 75th percentile can be considered as normal development. Each month, age range and gender also have a unique percentile average.

In fact, the percentile, evaluation and comparison of children of the same age and gender in terms of weight, height and head circumference! For example, let’s compare the heights of 50 boys attending first grade in a school. Here, the shortest child constitutes the 3-10 percentile value and the tallest child constitutes the 90-97 percentile value. At the 10th percentile for child age, this indicates that the children in his class are taller than 10 and shorter than 90.

In this case, if the child’s height, weight or head circumference is below the 10% threshold in the percentile table, that is, it is definitely necessary to consult his doctor. The cause of this problem is usually affecting physical development and It may be a nutritional deficiency causing growth retardation or a genetic problem! Therefore, if you see a problem in your percentile table and your child’s growth is insufficient for his age, you should not neglect to consult your doctor. According to the doctor’s instructions and the problem of the child, methods such as nutritional therapy and drug use may be in question.

How to track the perspective?

You will probably already be tracking your height and weight with the birth of your baby. But here The important thing is to know the correct values ​​and to support each other. For example, the child is 5 years old, his height is at the 50th percentile, in a normal state.
