Dad can find a folded page in the Children's Health Handbook, which is the growth curve of children. There are two sides, which are the percentile charts of the three growth indicators of boys and girls' length (height), weight and head circumference ... Each chart has five curves, representing the 97th, 85th, 50th,15th and 3rd percentiles of the same age group from top to bottom respectively.
Little knowledge! Original vs new version Because at home and abroad, most of the growth standards used in the past were formula-fed babies, and formula-fed babies gained weight faster than breast-fed babies. But the biggest difference between the new children's growth curve and the original one is that the standard of the new children's growth curve is that the World Health Organization has investigated the growth of breast-fed children growing up in a good and healthy environment in a transnational way. Therefore, it can avoid misjudging breast-fed babies as underweight.
Child growth curve? See through the child's growth curve? See through the child's growth curve? See through the child's growth curve? Step 3+ 1 How to use the growth curve of children at hand? As long as the simple steps are 3+ 1, please follow us to draw a healthy growth curve exclusive to your baby!
Step 1. Look at the abscissa first. Dad can find the baby's full term/age marked on the abscissa according to the baby's sex. For example, if the baby is 8 months old, choose the position that says "8 months" on the horizontal axis.
Step two. Find the ordinate, and find the values of length/height (cm), weight (kg) and head circumference (cm) on the ordinate respectively. For example, the height is 73 cm, look at the range between 70 and 73 cm, and find the position of 73 cm. Weight and head circumference also take the same way.
If we carefully look at the growth curve of children, we will find that there is a gap between the length/height curve at the age of 2, mainly because of the different measurement methods; Before the age of 2, the baby's body length is measured when lying down, and above the age of 2, the height is measured when standing.
The third step is to find the intersection point. According to the intersection point of the two lines just found, it is the baby's current growth point, which is equivalent to the percentage of babies of the same age. Take a boy who is 75cm long and over 1 year-old as an example. The figure of his body length percentage is in the 50th percentile, that is to say, among 100 babies 1 year-old, the boy is over 50, ranking in the middle.
Step4, connect the points into a line. From birth, dad can mark the baby's length/height, weight and head circumference one by one. The curve connected by these points is the baby's growth curve!
Point! Interpretation of growth curve Kelly Chen, a pediatrician at Guotai General Hospital, pointed out that generally speaking, if the growth index of a baby falls between the 97th and 30th percentiles, it is within the normal range; If it exceeds the 97th percentile or falls below the 3rd percentile, it is necessary to consider whether the growth index of the baby is too high or too low.
Child growth curve? See through the child's growth curve? Three indicators dad learned to check the growth curve of the child in the last paragraph, and he also knew which percentile the baby fell in, but what do these indicators mean? Too high and too short; What happens if you are overweight or underweight, or if your head circumference is too big or too small? How to deal with it?
Index 1, the average length of full-term newborns is about 50cm；; From birth to the sixth month, the average monthly height is 2.5 cm; From the seventh month to 1 year, the average length of each month is 1.3 cm, and the height is about 1.5 times that of the birth. In other words, the baby was born at 0? Between 65438 and 0 years old, it can grow to a height of about 25 cm.
After 1 year, the growth rate will gradually slow down, 1 year is about 10 ~ 1 1 cm; After 2 years old 1 it is about 8 cm older, and it grows about 5 ~ 6 cm every year before 6 years old. The average body length of school-age children is 4 cm a year. If the annual height growth is less than 4 cm after the age of 4, you should pay special attention. Then there will be another growth peak until puberty, even reaching a growth rate of one year 10 cm.
It's too high. Every parent wants their children to be "superior"! Dr Kelly Chen pointed out that, in fact, being too high is not a good thing, and precocious puberty may occur. Children who are too high can be evaluated by endocrinologists for their ideal height, and then combined with other tests (such as blood drawing) to rule out doubts about precocious puberty. Bone age must also be examined by X-ray to see if the pituitary gland is normal.
The method of bone age examination is very simple. You can judge the child's current bone age by taking an X-ray of the left palm. Bone age is not necessarily consistent with the actual age, and it is within the normal range to develop early or delay for 2 years.
