The standard height table for girls and the height and weight of children have always been a matter of great concern, so it also protects their physical development. Then there are differences in their height and weight at different stages. This is the standard height table for girls.

In addition, a formula is provided for mothers to predict the baby's future height: the adult height of a son (cm) = (father's height+mother's height) ×1.1(1.12)/2, and the adult height of a daughter (cm) =
For example, if the father is 170 and the mother is 160, then the minimum height of a baby girl in the future is (170*0.948+ 160)/2 and the maximum height is (170 * 0.98+).

note:
1, in the table, the length is before 3 years old and the height is after 3 years old.
2、 ? "Median" means being at the average level of the population;
If it is within the range of "-1sd~ median ~+ 1sd", it belongs to the "normal range", representing 68% of children; If it is within the range of "(-2sd~- 1sd)" or (+1sd~+2sd) ",that is, within the range of two standard deviations above and below the median, it is defined as" short (high) ",representing 27.4% of children; If it is within the three standard deviations of "(-3sd~-2sd) or (+2sd~+3sd)", it is defined as "short (high)", representing 4.6% of children. Very few children are outside the three standard deviations (+3sd) (the proportion is less than 0.5%).
Standard formula for infant weight measurement:
1-6-month-old weight (kg) = birth weight (or 3kg)+month-old ×0.6 (kg)
7-65438+February weight (kg) = birth weight (or 3 kg)+month age ×0.5 (kg)
2- 10 years old weight (kg) = age ×2+7 (or 8)
The growth law of infant height standard;
The average length of a full-term child is 50 cm, which increases by about 25 cm in the first year after birth, so it is about 75 cm at the age of one. After that, the average annual growth will be about 5 cm, so the length of children after 2- 12 years old (cm)= age ×5+75 (cm). Anyone whose height exceeds the standard 10% or is lower than 10% is regarded as abnormal.
Measurement method of children's height and weight
Weight measurement
Newborn babies are measured by professional doctors in the hospital, and then they can be measured during physical examination or at home regularly. Pay attention to the following details when measuring:
1, which can be directly weighed in summer. Take off the baby's coat, shoes and socks and hat before weighing.
2, if measured in winter, in order not to let the baby catch cold, you can let the baby wear clothes first, and then estimate the weight of the clothes and subtract its value.
3, to measure when the baby is on an empty stomach, it is best to measure after defecation.
measurement of elevation
It is best for two people to measure the baby's height together. One person fixes the baby's knee joint, hip joint and head by hand, and the other person measures it with a tape measure, from the highest point of the baby's head to the highest point of the foot. The measured value is the height of the baby.
Props: Two heavy and difficult books (such as dictionaries) and a tape measure.
Methods: when the baby is asleep, gently stick a book on the baby's head; Then put the baby's body straight, press the baby straight with one hand, and put another book behind the baby's soles with the other hand; Finally, after the two books stand firmly, gently move the baby away. At this time, the distance between the two books is the height of the baby.
Reminder: You don't need to measure your baby's height every day, just once every two or three weeks.
Factors affecting children's height
1, genetic factors
The baby's height, physical strength and developmental state are greatly influenced by parents' genetic factors. If parents are tall and strong and free from diseases, the growth and development of infants and young children will have a good foundation. If parents are in poor health and have hereditary diseases, the chances of infants' growth being negatively affected are high.
However, genetic factors are not absolutely immutable. For example, by exercising, paying attention to nutrition and strengthening the prevention of diseases, children can be improved and improved on the basis of the original biological inheritance, so that children can grow and develop normally.
Because the baby's height is greatly influenced by heredity, the baby's future height can be predicted to some extent from the height of parents. The formula is as follows:
Boy's future height (cm) = (father's height+mother's height) × 1.078÷2
Girl's future height (cm) = (father's height ×0.923+ mother's height) ÷2
2. Mother's health factors
The health care and nutrition of mothers during pregnancy and lactation are directly related to the growth and development of babies. Pay attention to nutrition during pregnancy and lactation, and pay attention to preventing various diseases, especially infectious diseases.
3. Nutritional factors
Nutrition has a great influence on physical development, especially on weight. The younger the age, the greater the influence. Because babies grow and develop fast, they need higher quality food than adults. Nutritional factors mainly refer to adequate nutrient supply and reasonable feeding methods.
Pay attention to health care during pregnancy to ensure adequate nutrition for pregnant women; Breastfeeding babies as much as possible and adding complementary food; It is necessary to improve the dietary nutrition of infants and pay attention to the quality of breakfast.
4. Sleep factors
Growth hormone secreted by pituitary gland is an important hormone to stimulate children's growth and development.
The secretion of human growth hormone is unbalanced within 24 hours a day, and the secretion during sleep is higher than that during awakening. Lack of sleep will affect children's growth. Newborns are generally required to sleep 20 hours day and night every day, with 15 ~ 18 hours from February to June. June-August is 13 ~ 15 hours; 65438+8 months to 3 years old is 12 ~ 13 hours.
Children's sleep time varies greatly from person to person. If some children sleep less, but their spirits, emotions, growth and development are normal, there is no need to force them.
5. Sports factors
Exercise can promote blood circulation, improve bone nutrition, accelerate bone growth, make bones tight and promote body length growth.
Children 3 ~ 4 months ago should lie prone several times a day to promote whole body activities. With the growth of months, they should cultivate basic abilities such as turning over, climbing, standing and walking in time.
Children should not hold or sit for too long. Children's whole body activities are inconvenient, and sedentary will affect the development of lower limbs. After children learn to sit, they are often reluctant to learn to turn over and climb. Regular physical exercise is also an important way to enhance physical fitness.
6, living environment factors
Infants and young children should live in a good environment, with fresh air and plenty of sunshine. Coupled with exercise and nutrition, children will grow faster. Throughout the year, weight gain is fast in autumn and body length growth is fast in spring.
7. Disease factors
Many diseases will affect the growth of children's height. Generally, acute diseases only affect weight, while chronic diseases affect height. If the child's height is always lower than 10% of the average height of children of the same age after long-term measurement and observation, it is called growth retardation; If it is less than 30%, it is abnormal, and it is necessary to diagnose and treat it in time.
