Newborn weight algorithm, newborn weight calculation formula

An algorithm for the weight of the newborn, this you can say that the query king is related, and the other is to say the calculation formula, he has a calculation formula.

The calculation of the weight of the newborn is generally based on the weight scale used for the newborn.

The weight of the first sound is calculated according to his height, and then according to his growth!

Newborns generally weigh about kilograms.

The formula for calculating the weight of a newborn is as follows:1. Fetal weight (grams) = 900 double parietal diameter - 5200.

2. Fetal weight (grams) = double parietal diameter 3 + abdominal circumference 2 femur length.

3. Fetal weight (grams) = femur length.

4. Fetal weight (grams) = thickness of subcutaneous fat in fetal legs.

5. Fetal weight (grams) = head circumference + abdominal circumference + femur length + fetal leg subcutaneous fat thickness.

6. Fetal weight (grams) = head circumference.

7. Fetal weight (grams) = fundus height and abdominal circumference 200.

8. Fetal weight (grams) = abdominal circumference. Zen Weiyan.

Factors influencing the birth weight of newborns1. Age of primiparity.

The age of first birth is under 30 years of age, and the birth weight of newborns increases with the age of the pregnant woman, and decreases with age over 31 years.

2. Gestational age. A baby that is in the mother's womb for too short or too long can affect the birth weight of the newborn. At 35 to 39 weeks of gestation, the birth weight of newborns increases significantly with the increase of weeks

At 40 to 43 weeks of pregnancy, weight gain is slower; After 44 weeks of pregnancy, weight decreased.

3. Parity and multiple births.

The birth weight of the second and fifth births is increasing compared with the first birth, and the weight of multiple births is generally lower.

4. Pregnant women's hobbies.

Smoking in pregnant women can cause newborns to weigh less than normal.

The weight formula depends on what age the toddler is in.

If it is an infant before the age of 2, then the corresponding weight formula is the weight of the first half year (kg) = birth weight + month age; Weight in the second half of the year (kg) = birth weight 6 months of age -6).

If it is a child between 2 and 12 years old, then the corresponding weight (kg) (age) 2+12 age 2+8.

Pregnant mothers are more concerned about all aspects of the fetus after pregnancy, and pregnant mothers are not willing to let go of any information about the fetus. Fortunately, there is some scientific software available for everyone to use. Next, let's take a look at the fetal weight calculation formula.

Fetal weight** formula.

Explanation of the formula for calculating fetal weight.

The above formula is only an estimate of the baby's weight and does not represent the actual birth weight of the baby. **The purpose of fetal weight is to detect problems in fetal development early. In general, there will be a difference of plus or minus 10-15% between the actual weight at birth and the ** weight.

For example, a birth weight of 4,000 grams will have a margin of error of 400 grams. In other words, the greater the baby's weight, the greater the margin of error.

The above is a compilation of information about fetal weight calculator software. The above are some calculations based on some conventional data, which can also be deduced from the above in the absence of software, but there are still some ** with software. Here I suggest you can take a look.

Hopefully, I'll have to sort it out and it will help you.

According to the ninth edition of Pediatrics, the formula for calculating the weight of children aged 3-12 months is (month age + 9) 2, the unit is the age of the child, the weight calculation formula is age 2+8, and the weight calculation formula for the child who is also the age is (age 7-5) 2, and the unit is also kg.

In general, the value of weight gain is equal in the first three months and nine months after the birth of a child. The weight of the child at birth is generally 10kg, and the weight gain in the first two years of life is. Thereafter, from the age of two to puberty, the child's annual weight growth is about 2 kg.

Infants and toddlers are generally referred to as children aged 0-7 years. There is a great connection between infants and young children, so many children's treatises, medical treatises, early childhood education, etc., will be used together to make it easier to understand.

Although they are closely related, there are two differences in terms of child development, one is infants (0-3 years old) and toddlers).

Sleep for infants and toddlers:

Sleep 14-15 hours a day, 1 2 times during the day.

The growth in length and weight of young children has slowed compared to babies under 1 year of age. The total length of the first year of life increases by about 25 cm, and the growth rate of length gradually slows down after the age of 1, and the annual length increases by about 10 cm within the age of 1 and 2 years. After the age of 2, it is slower, with an average annual growth of about 5 cm. After the age of 1 year until the school age, the average weight of children increases by about 2 kg per year.

Usually, children gain more weight before the age of 3 years, and the height gain is faster than that of the 3 to 7 years of age. 1 Three-year-old children still have a long trunk and relatively short lower limbs. Due to the increased activity, it is normal to look less fat than in infancy.

The above content refers to the encyclopedia of infants and toddlers.

The minimum value of the child's monthly weight gain is: 0 600 grams of normal growth in 6 months; 6 December normal growth value 300 g month. If the monthly gain value is less than this standard for two consecutive months, the doctor thinks that the child's weight gain is insufficient.

Formula for calculating baby weight at different stages:

Weight within 6 months, birth weight, age in months: 600 grams.

7 12 months weight Birth weight Age 500 g 2 7 years weight Age 2 8000 g.

The centimeter is increased in half a year, and the average centimeter is increased every month.

Male: Average. centimeters (centimeters).

F: Average. centimeters (centimeters).
