It is said that "the father is short and short, and the mother is short and the nest".
We all expect ourselves to grow taller, if we don't reach the target weight, we put our hopes on the next generation, what is unknowable is that each child's genes are different, the growth environment is different, so children also have different growth potential. In order to ensure that the child is not short, it is necessary to establish a reasonable prediction about the future height, adjust the child's diet and growth environment according to the prediction, and maximize the help for the child to grow tall.
so...
What are some ways to predict your child's height?
Is the height prediction method more accurate?
This article mainly discusses the commonly used scientific prediction of children's height method, and introduces several methods that can predict the height of children in detail for parents, so that parents can have an in-depth understanding of their children's future height development intervals.
The topic of a child's height never goes out of style.
Xiaobian has a classmate, very good-looking, but a little short, when looking for a partner, he is particularly concerned about the height of the other half, and he is particularly determined.
In the end, her marriage partner was indeed a 180 boy, but it was a little dark, but the classmate said:
"It doesn't matter, I don't mind if the kids look black, as long as they don't get as short as I am."
Many parents worry that if they or their other half are not tall enough, their children will be shorter in the future, and even because of such worries, they will affect their mate selection standards, for fear of affecting the next generation.
There is also a small program on the Internet that can predict the future height of the child, and you can predict the future height of the child by entering the child's gender, age, height, weight, and the height of the father and mother.
A friend of mine saw it and asked me if it was reliable.
I checked it and found that it is not difficult to predict the height of children in adulthood, and there are more than one way to predict, including: B-P method, TW method, RTW method, target height prediction method, infancy-childhood-adolescent growth model, coefficient method, adult height prediction method for children with abnormal growth and so on.
Today we will introduce several:
B-P法
The B-P method mainly predicts the height of children based on bone age.
In 1946, a researcher at the University of California in the United States first proposed a percentage method for predicting adult height, and later designed and published the "X-ray Atlas of Wrist Bone Development".
When we go to the hospital to measure the age of the child's bone, we will find that the doctor is taking X-rays on the child's hand, which is also called the G-P map, and this prediction method is still used in specific areas in many countries.
The most common and traditional methods of predicting bone age are as follows:
1. Bone age is judged according to the number of ossified centers of the wrist
Observe the number of ossified centers erupting from the wrist of the child to determine the maturity of bone development:
If the skull or hook bone appears, the bone age is equivalent to 6 months;
When triangular bone appears, the bone age is equivalent to 3 years old...
This method is more suitable for children before the age of 7 years.
2. Judge the bone age according to the X-ray map of the wrist
The X-ray of the child's wrist is compared with the standard atlas, and when the number, morphology, and size of the ossification centers of the child's wrist are more consistent with the ossification centers shown at a certain age in the standard atlas, the age on this map is the age of the child's bone.
The atlas is set in male and female sets, suitable for children aged 0-19 years.
Parents who want to predict their child's height through B-P can go to a regular hospital to measure their child's bone age to see if the child's bone development is in line with age.
Target height prediction method
The so-called target height, which means the genetic potential of height, is used to use the median height of the parents.
In the target height prediction method, this method believes that the elevation of parents has an impact on the height of the child, and has a wide range of clinical applications, and many testing software uses the prediction formula of the target height:
Girl: (Dad height - 13cm + Mom height) ÷2
Boys: (Mom height + 13cm + Dad height) ÷2
The formula is very simple, you only need to substitute yourself and your other half's height according to the child's gender.
However, this result can only be a prediction, how tall the child will grow in the future, there will be a certain deviation.
Because of how tall it grows in adulthood, congenital genetic factors account for most of it, and the acquired diet, sleep, and exercise also have a certain impact.
Genetic formulas predict height
Anyone who usually watches the news knows that the World Health Organization has released a genetic formula for the height of Asians, as follows:
Boys: (paternal height + female height +13)/2±7.5 cm
Girl: (paternal height + female height -13)/2±7.5 cm
For example, if Xiaohua's father is 175cm and her mother is 163cm, then Xiaohua's genetic height is (175+163+13)/2=175.5;
If the acquired development is good, the child can also add 7.5cm, that is, 183cm, which is also very in line with the phenomenon that many children are generally tall.
Wallkel's prediction method
The Wallkel prediction method is a relatively simple final height prediction method, which uses the height of children and adolescents at a certain period to predict the final height in the future, or the final height is obtained after comparing the height of two periods.
This method has a certain degree of reliability and is widely used in height prediction.
One-time prediction method:
Final Height = A + B × Height for the year
Example: A boy's height at the age of 9.5 is 130 cm.
Predicted final height = 71.86 + 0.78 × 130 = 173.26 cm
The values of A and B can be calculated by referring to the following table:
Two-time forecasting method:
Final height = A + B1 × Height + B2 × (first and second height difference ÷ number of months apart)
Example: A boy 9.5 years old, the first measurement of height is 130 cm, eight months later the height of 132.4 cm.
Predicted final height = 70.85 + 0.8 × 130 + (-0.3) × [(132.4 - 130) ÷ 8] = 173.95 cm
The values of A, B1 and B2 can be calculated using the following table:
FPH height prediction method
Boys: Y (final height) = 45.99 + 0.78× average parental height ± 5.29 (cm)
Girls: Y (final height) = 37.85 + 0.75× average parental height ± 5.29 (cm)
Standard height for boys and girls 1-18 years old:
Then again, although the formula can predict the approximate height of the child, it has to be said that there are still many exceptions, if you can do scientific baby raising, it may still exceed the calculated height, if the child's living conditions are poor, it may also be shorter than the calculated height.
Anyway, things are man-made, parents do their best!
