Recently, I found that some parents don't know much about this business.

Tools are good tools. I'm sorry you can't use them.

Growth curve subclass

We talk about it

The first point: the origin and function of the growth curve.

-1993, who abandoned the old curve and proposed to draw a new growth curve. During 1997 ~2003, a multi-center growth reference standard was studied to develop a new curve to evaluate the growth and development of children all over the world.

Data were collected from 8,440 healthy breast-fed infants from different ethnic backgrounds and cultural environments (Brazil, Ghana, India, Norway, Oman and the United States).

-Deliberately choose healthy children who live in conditions that may be conducive to the full realization of their genetic growth potential.

-Mothers who were chosen as the standard breast-fed and did not smoke.

-The growth curve can best describe the physiological development of children under five years old.

-This standard describes the normal growth of young children under the best environmental conditions.

-It can be used to evaluate children anywhere, regardless of their race, socioeconomic status and feeding style.

In fact, from the background and starting point of the growth curve formulated by the World Health Organization, we can know that the growth curve is an important reference standard for children's growth and development.

We can draw a child's growth curve and find out the situation that may need attention and adjustment in feeding.

Because the data samples collected by the growth curve production come from healthy breast-fed babies and their mothers with different lifestyles and eating habits in different parts of the world, it is more representative and universal, and can be used as the evaluation standard for children in all countries of the world, including China.

Second, how to do the growth curve?

Two versions: baby boy and baby girl.

N Multi-parameters: age/height/weight/body mass index (BMI)/head circumference/hip circumference/skinfold thickness under shoulder/triceps skinfold thickness/sports development milestone/weight speed/head circumference speed/height speed, etc.

Generally, we use the curve table of age/height/weight.

(For example, we use the 0-2-year-old version of the World Health Organization's Collection of Women's Age/Height and Weight, with tables for 0-6 months and 0-5 years old. Parents can choose to make curves more conveniently according to their age. )

1, weight gain curve

This is the growth curve of age/weight.

Find the corresponding month age on the horizontal axis (age axis): 0, 1, 2, 3 months;

Find the weight values on the vertical axis (weight axis): 3.2, 4.3, 5.8 and 6.5kg；;

Draw a point at the intersection of age and weight every month. By analogy, connect the corresponding points into a line, which is the weight curve of this female baby.

2. Height growth curve

This is the growth curve of age/height.

Find the corresponding month age on the horizontal axis (age axis): 0, 1, 2, 3 months;

Find the height values on the vertical axis (height axis): 50, 55, 58, 63cm,

Draw a point at the intersection of age and height every month. By analogy, connect the corresponding points into lines, which is the height curve of this baby girl.

If it is a boy's baby, you only need to do it on the growth curve of the World Health Organization Men's Treasure Edition, and the method is the same.

Third, the growth curve is done, how to interpret it?

1, depending on the overall range of the growth curve.

Look at the far right, there is a string of numbers 3-97. The significance of this string of numbers is that there is a string of numbers 3-97 on the far right side of the growth curve. The significance of this string of numbers is to rank the height of 100 boys of the same size from low to high, if the baby ranked third falls on the curve of 3.

We usually think that the curve between 3 and 97 is normal, and not all children have to fall on the line of 50 to be normal.

2. Look at the general trend of the growth curve.

It is more important to look at the overall trend of the whole curve than to see whether each value falls within the normal range.

The overall trend is steady growth, so we say that the child's development is ok. Of course, it is possible that children will skyrocket in the early stage and be flat or the opposite in the later stage.

For example:

2. 1 Overall gentle rising curve:

2.2 The early stage is relatively gentle, and there is a catching-up curve in the later stage.

3. Look at the fluctuation range of the growth curve.

When the above-mentioned non-stationary uniform growth and curve fluctuation occur, how to interpret it?

3. 1 normal curve:

Slight fluctuation on any curve of 3-97

3.2 Normal curve:

Fluctuates in the interval between two curves.

3.3 It should be noted that:

The curve broke through two intervals and continued to rise. It is necessary to check whether the child's eating is on demand and whether the activity is enough.

3.4 It should be noted that:

The curve broke through two intervals and continued downward, even falling out of the curve of 3%. It may be a problem of stunting, and it is necessary to investigate the child's intake, physical pain and other reasons.

Mom and dad know how to make and interpret the growth curve. Are they more sure about the baby's development?

Of course, children's development can't be fully expressed and explained by a series of numbers and a curve. Children are three-dimensional and multidimensional. As parents, what we need to do is to insist on breastfeeding, increase parent-child interaction, give children more acceptance and love, and create a harmonious family atmosphere and enough room for growth and exploration.
