What is the normal weight and height of a 12 year old girl?

At present, there is no unified standard weight data in China. There are two most commonly used calculation methods:

One is: Adult: (Height (cm) - 100 0 9= Standard weight (kg).

The other is: male: height (cm) 105= standard weight (kg), female: height (cm) 100= standard weight (kg).

The above two calculation methods have been widely used.

In addition, the Academy of Military Sciences has also introduced a method for calculating the ideal weight of Chinese:

Ideal weight for northerners (kg) (height cm 150) x 0 6 50

The ideal weight of southerners (kg) (height cm 150) x 0 6 48, this calculation method seems to be more suitable for Chinese in the north and south.

The simple way to calculate the standard weight of a child is: 1 6 months: birth weight (kg) 10 years old standard weight (kg); 7 12 months:

Birth weight (kg) 10 years of age x 0 5= standard weight (kg); Over 1 year: 8 ten years of age x 2 = standard weight (kg).

Within the range of standard body weight +-10. Exceeding this range is referred to as an abnormal weight.

Those who have a measured weight that exceeds the standard body weight, but exceed the part by 20 are called overweight;

Obesity can be diagnosed if the measured weight exceeds the standard weight by more than 20 and the fat percentage (f) exceeds 30.

Those who weigh more than 30 to 50 of the standard body weight, and those who exceed 35 to 45 are called moderate obesity;

Those who exceed the standard body weight by 50 or more, and F who exceed 45 or more, are called severe obesity. Satisfied.

Generally, it fluctuates between 40-50kg, and if it is in this range, it is considered normal.

This is a rough estimate, and this standard is not accurate for 12-year-old girls, because the puberty of girls generally begins at the age of 9-10, and the average age of puberty is 11 years old, roughly in the range of 8-14 years, and the whole puberty development lasts three to three and a half years, but it can also be two years or longer, up to 5-6 years.

Children are in the period of puberty, we must pay attention to a balanced diet and nutrition, the combination of work and rest, appropriate outdoor exercise and sun, which is conducive to physical development.

At birth: Normally about 50 cm tall at birth.

Year 1: The first year of life is the first peak of the baby's height growth, about 25 cm, of which about 11 12 cm in the first 3 months and about 61 62 cm at 3 months.

Year 2: In the second year of life, the baby's height growth rate begins to slow down, growing by about 10 cm a year, and the baby's height is about 85 cm at the age of 2.

After 2 years of age: After the age of 2, the baby's height begins to grow steadily, growing by about 5 7 cm per year.

2 The height of a 12-year-old child can be calculated using such a formula. i.e. age *7 (5) 70 cm.

Then your height is 130 154cm.

But you can also use your height to calculate your weight, which I think is more accurate.

The standard weight for women is: height (cm) 110 = standard weight (kg).

47 is your standard weight, and you're on the underweight side.

157 is overnourished for a child who is almost twelve years old, that is, it can be regarded as early development, which is very high.

It's not a good thing to develop early, and you may not develop later when other children develop. It is recommended that you go to the hospital for a look.
