First question: What do you mean by the child's height and weight?
From 65438 to 0993, the World Health Organization (WHO) conducted a comprehensive survey on the use and interpretation of anthropometric reference standards.
Looking back, the reference standard of children's growth can't fully reflect the growth of children, so they are distinguished by different heights and weights.
Second question: Why never say goodbye?
According to the world health organization's child growth standards.

Nouns explain height and weight.
A person's height is 1.75m and his weight is 68kg, and his body mass index = 68/( 1.75 2) = 22.2 (kg/m 2). The body mass index is normal at 18.5 ~ 23.9.
Body mass index (BMI) is an index closely related to body fat, which takes into account two factors: weight and height. Body mass index is simple and practical, which can reflect the overweight and obesity of the whole body. It is more accurate to measure the risk of heart disease, hypertension and other diseases due to overweight than to identify them simply by weight.
What do you mean by height and weight?
How tall are you? How much do you weigh
What do you mean by height and standard weight?
It is to measure the actual height and weight of students, and then compare the corresponding value of the standard weight of students' actual height with the actual weight of students. Then you will know whether the student is fat or thin now.

52 >； What do you mean by height and weight? What is its definition?
(1) Measuring height and weight can judge people's growth, development and body shape.
Whether the development is normal or not is usually judged by age, height, weight, foot characteristics, intelligence and other indicators and their relationship. When the development is normal, the growth state of age and physique is adaptive. Healthy people can see their physique growing every year before they grow up, and puberty can have a particularly fast adult speed, which is a normal development state. Normal development is closely related to national heredity, endocrine, nutritional metabolism, living conditions, physical exercise and other factors.
The growth and development indicators of children have been mentioned above, and the indicators for judging the normality of adults are: the chest circumference is equal to half of the height; Finger distance (the distance between two upper limbs and two middle fingers) is equal to height; The upper body (from the upper edge of pubic symphysis to the top of the head) is equal to the lower body (from the upper edge of pubic symphysis to the sole of the foot). If it is obviously asymmetrical or disproportionate, it belongs to dysplasia.
Body shape refers to the development of various parts of the body, including the growth of bones and muscles and the state of fat distribution. Clinically, there are three kinds of normal people.
(1) Symmetric type: the structure of all parts of the body is symmetrical, which is common in normal people.
(2) stout type: from the height point of view, the weight is biased, the finger distance is slightly smaller, the upper body is slightly longer, and the lower body is slightly shorter. Its appearance is short and stout, its neck is thick and short, its shoulders are flat, its chest is wide, and its upper abdomen angle is greater than 90 degrees. Humpty people tend to have high blood pressure, strong digestion and absorption ability, and are more prone to obesity, gallstones and arteriosclerosis.
(3) Slender type: contrary to stout type, tall and thin, with slender neck, drooping shoulders, flat chest and upper abdomen angle less than 90 degrees. Slim people often have low blood pressure, poor digestion and absorption ability, and are more prone to diseases such as visceral ptosis and tuberculosis.
Pathological development is closely related to endocrine, and abnormalities will occur in pituitary gland, thyroid gland and gonad, resulting in abnormal development and body shape.
When the anterior pituitary gland is hyperfunctional before maturity, its physical abnormality is as high as "gigantism"; On the contrary, pituitary dysfunction and abnormal short stature are called pituitary dwarfism. If the anterior pituitary gland is hyperfunctional after maturity, it will suffer from acromegaly, which is characterized by enlarged head, longer face, enlarged mandible, protruding forward, raised eyebrow arch and zygomatic region, enlarged lips and tongue, and enlarged ears and nose.
When hyperthyroidism occurs, metabolism increases and appetite increases, which makes the body develop more than normal; If it is reduced, it will be short stature and mental retardation, which is called "dementia".
Gonadas also have a certain influence on physical development. For example, precocious puberty, physical development faster than children of the same age, but will cause early healing of epiphysis, limiting later physical development. Gonadal secretion is closely related to the development of secondary sexual characteristics. Some diseases, such as tuberculosis and tumors, destroy gonadal secretion function and can cause changes in secondary sexual characteristics. For example, male patients have "eunuch" sign, which is characterized by long upper and lower limbs, wide pelvis, no beard, sparse hair, plump subcutaneous fat, stunted external genitalia and sharp voice like a female voice. If it is a female, there will be hypoplasia, amenorrhea, male physique, hirsutism, subcutaneous fat loss, and a deep voice like a male voice.
In addition, malnutrition in childhood may affect normal development. For example, when vitamin D is deficient, you can suffer from rickets, such as square skull, chicken breast, beaded ribs, valgus of lower ribs, O-shaped legs, X-shaped legs and so on.
(2) You can judge whether you are fat or thin by measuring your height and weight.
There are medical criteria for judging whether you are fat or thin. There are more than ten criteria for judging, and there are two commonly used ones. The first calculation formula is:
Standard weight: height (cm)-100= weight (kg)
This is an international standard, which was revised to our national standard weight according to our national day: height (cm)- 105= weight (kg). According to the above formula, women's income will be reduced by 2~3kg/
Based on the standard weight, it is normal to increase or decrease within 10%. 10% of body weight is "overweight"; More than 20% are "obese". Anything below 10% is "weight loss" and anything below 20% is "emaciation".
Now, a new formula has appeared in the world, that is, body mass index (or BMI), which has been recognized by the medical community. Its calculation formula is:
Body mass index (BMI) = weight (kg)/[height (m) ]2
The "China Obesity and Disease Symposium" held on 200 1 released the summary and analysis report of obesity in China in 1990s, and revised the obesity standard of China population according to experts' suggestions.

How to ask someone about their height and weight in Korean?
How tall are you?
How much do you weigh Fines;
Weight should be proportional to height? what's the meaning
You can think of it this way. If someone is tall and light, it means that this person is very light, that is, thin; If someone is short and heavy, it means that he is overweight, that is, fat. Therefore, judging obesity has a ratio standard of weight and height.
Male: height (cm)- 105 = standard weight (kg) Female: height (cm)- 100 = standard weight (kg)
What does it mean to be below average in height and weight?
low
Standard weight = (height-1 10) kg. What do you mean?
At present, it is recognized in the medical field that the body mass index (BMI) is the measurement standard for calculating body fat rate, and the formula is the square of mass (kg)/ height (m). The normal body mass index of orientals is 18.5 ~ 23.9. If it is 24 ~ 27.9, it is overweight; If it is greater than 28.0, it is obesity. According to statistics, the overweight rate of adults in China is 22.4%, and the obesity rate is 3.0 1%. Prevention and control of obesity is a top priority in China.
Physical examination of national military academy enrollment: standard weight (kg)= net height (cm)- 1 10.
Men's actual body mass index is allowed to be at the standard body mass index (+25%,-15%) and women's at the standard body mass index (15%,-15%).
Net height 175cm, so the standard weight =175-10 = 65 kg, and the standard body mass index is 22.2.
If the net height is 175cm and the weight is above 70kg, it is overweight and the body mass index is above 24. If the net height 175cm and the weight is above 82kg, it belongs to obesity and the body mass index is above 28.
Actually, my body mass index is 22.9 175cm, about 67kg, which is a little heavy, but it is still within the normal range.
If the net height is 165cm and the standard weight is about 55 kg =165-10, the standard body mass index is about 2 1.5.
If the net height is 165cm and the weight is above 62kg, it is overweight and the body mass index is above 24. If the clear height is 165cm. If you weigh more than 72kg, you are obese and your body mass index is above 28.
For girls, if the net height 165cm, the weight should be controlled within 65kg (body mass index 25.2).
As can be seen from the above, in real life, men are obviously overweight than women. It may be because women love to lose weight (I find that men are overweight, but after seeing more overweight men, women will think that men with normal height and body mass index are thinner).
What is age-specific weight?
Specific age weight
. The weights of longitudinal and transverse samples are combined without any adjustment and fitted.
A single model generates a series of continuous curves, forming a specific age weight standard for each sex. Zaiquasi
Before modeling the curve, the same exponential conversion operation is used for the ages of boys and girls. both sexes
The weight data is skewed, so when expressing the model, except the median and approximate coefficient of variation, it is skewed.
The related parameters are also fitted. When fitting skewness, the girl curve needs more freedom for this parameter.
The numbers fit the curve.

Enter. However, the adjustment of kurtosis has little effect on the final percentile. Therefore, considering the fitting
The fourth argument may make the application of standards more complicated and lead to the inconsistency between the two sexes, which will lead to the final song.
There is no adjustment of kurtosis when drawing lines. The degree of freedom of median and variance curves is different between boys and girls.
