Children's height and growth rate

A person's height depends on the regulation of heredity, nutrition and endocrine hormones on the growth rate. Under normal circumstances, there are two peaks in height growth. The first peak is from birth to 3 years old, and the second peak is adolescence. For parents, mastering the law of children's height growth is helpful to find the abnormality of children's height early, so as to take corresponding treatment or intervention measures earlier.

In addition to checking the "height standard table", parents can also make a simple estimate of their children's height. Children's growth and development have certain rules, generally fast first and then slow. The average length of a child at birth is 50CM, and it grows 4 cm every month in the first three months after birth. After 3 months, it will increase by 2 cm per month; In the last 6 months, the body length is about 75CM every month 1CM, 1 year.

The growth in the second year is about 1 1~ 12CM, that is, the body length is about 85CM at the age of 2.

After 2 years old, the height increases by 7CM every year. Roughly estimated height of 2~ 12 years is: height (CM)= age *7+77(CM).

Careful parents can refer to the above rules or compare them with children of the same age. If it is found to be obviously abnormal, or obviously lower than the average level of children of the same age, it is necessary to consult relevant experts in children's endocrinology department in time.

Set the height before the age of 3?

From birth to adulthood, the growth rate of height is not uniform. When you are born to 2 years old, your height will generally grow to 28cm, of which 1/3 will be completed 4 months ago, which are 5-65438+February and 1-2 years old respectively. The influence of nutrition before 2 years old on growth far exceeds genetic factors, especially at a younger age. From 2 years old to before puberty, it grows at a constant speed of 5-7cm every year until puberty accelerates for the second time.

In other words, an adult with a height of 170cm is above 1/3 from birth to 2 years old. This different growth ability of different age groups is caused by the complex regulation of endocrine. If you are affected by harmful factors such as nutrition, diseases or drugs before the age of 3, the damage to your height will be permanent.

Master 9 secrets of children's golden age

1, read the height signal.

When will the child's height soar? There are two signals that can tell you. The first signal is that the child's appetite is greatly increased, and his appetite is very strong, indicating that he is going to grow up. The second signal is that children's shoes suddenly become smaller, which is also a signal of growing up. Because children usually jump from the bottom: when their feet get bigger, their legs get longer, then their hands get bigger and their arms get longer.

2. If you grow fast, you must keep up with nutritional supplements.

The rapid growth of children means that the formation of bones is obviously faster than that of children of the same age, so the demand for calcium, an important component of bones, is even greater. In order to ensure the absorption and utilization of calcium, the demand for vitamin D will increase accordingly. At the same time, the formation of bones also involves phosphorus, zinc, vitamin A, vitamin C and other related nutrients.

Drinking milk before going to bed is the key.

Milk is the main food source of calcium, and calcium is the basic raw material for children's bone growth; Milk can also promote sleep, so drinking a glass of milk before going to bed can promote the height growth of children. However, it should be noted that if the child is over 3 years old, it is best to choose low-fat milk for him, because the saturated fat content in full-fat milk is high, and children who drink full-fat milk for a long time are likely to have high cholesterol. Therefore, children should develop the habit of drinking low-fat milk, which can not only ensure the intake of calcium, but also reduce the intake of saturated fat.

Reasonable consumption of meat

Meat, especially beef and lean pork, is rich in trace element zinc, which is the main source of zinc for human body. Zinc can promote the growth of children. Many important enzymes involved in metabolism in human body contain zinc, which is necessary to maintain the activity of these enzymes.

Get enough sleep

Generally speaking, the younger a child is, the longer he needs to sleep. Newborns sleep about 20 hours a day, and babies of 2 ~ 6 months sleep 15 ~ 18 hours a day. Sleep 13 ~ 15 hours every day for 6 ~ 18 months; 18 months to 3 years old children sleep every day 12 ~ 13 hours; Preschool children sleep 1 1 ~ 12 hours a day, while school-age children still need to sleep 9 ~ 10 hours.

Of course, how many hours children sleep every day varies greatly from individual to individual. Therefore, adequate sleep is not necessarily measured by time. It is important to see whether the child is easy to fall asleep, whether the sleep is stable and deep, and whether he is full of energy and high spirits when he wakes up.

6. Too fast growth is not necessarily good.

Children grow slowly, and parents are generally anxious and busy taking their children to see a doctor. Children are taller than their peers, especially when their parents are short and their children are tall and big. Many parents are proud that their children will grow up in the future. In fact, just because a child grows up too fast doesn't necessarily mean that he will be a big shot in the future. Because premature development may mean premature cessation of development, and ultimately the height is not ideal.

7. Don't let obesity affect your growth.

Obesity is one of the important causes of precocious puberty in children. Precocious puberty will advance epiphyseal closure, so at first obese children seem to grow rapidly in height, but in the end their height will be affected.

8. If you want to grow taller, please stay away from repeated respiratory infections.

During the illness, children usually don't eat much, and their nutrient intake itself decreases. Fever increases energy consumption, resulting in no weight gain or even decline. The recovery of weight gain is related to the duration of the disease, the severity of the disease and the frequency of illness. If respiratory tract infections recur and the body has not fully recovered to catch up with growth, it will suffer a new blow, further reducing the nutritional status and resistance of the body. After a long time, it will obviously affect the growth of children's height.

9. Hormone therapy should be treated dialectically

Long-term oral administration of a large number of hormones will affect calcium and phosphorus metabolism, lead to osteoporosis, inhibit bone growth and protein synthesis, and then affect children's growth and development.

But parents don't have to talk about hormonal discoloration. Because now doctors pay more attention to small doses and local use of hormones for children, which is different from systemic use of hormones. Therefore, as long as the use of hormonal drugs is standardized, it will not have a significant impact on the growth and development of children, and parents do not have to have the psychology of "fear of hormones".

Finally, I will give you a brief list of recipes that were too long before.

Five dietary keys to help children grow taller

▊ Focus 1: Balanced diet

The growth of human body comes entirely from the quality of imported food. If you want your child to grow taller, all kinds of nutrition should be balanced. Make sure to eat 25 ~ 30 kinds of food every day, which is much richer than eating only three or five things a day.

Recommended food vegetable and fruit salad: cucumber, apple, banana, onion, lettuce, pear, orange, etc. Cut into small pieces and put them in a bowl. Pour in salad dressing.

Cereal porridge: rice, black rice, red beans, dates, raisins, etc. Wash and cook together 1 hour.

Jambalaya: Put oil in the pan. When the oil is hot, add eggs, peas, sweet corn kernels and ham. When the rice is cooked, add rice and stir fry together. Finally, add cucumber and shallots and stir fry a few times.

▊ Point 2: Calcium should be sufficient.

Calcium is the basis of bone growth. If you can't get the calcium required by physiology in your diet regularly, and the calcium in your blood and soft tissues is insufficient, you must get calcium from your bones. Lack of calcium in your bones will lead to osteoporosis, spinal deformity and spinal curvature. Without adequate nutrition, bones can't grow normally, let alone grow taller.

Recommended foods containing more calcium are: dairy products, eggs, fish, shellfish, tofu and beans, sesame paste, pumpkin seeds, etc. (vitamin d, vitamin c, lactose, etc. Both contribute to the absorption and utilization of calcium).

▊ Point 3: protein has it every day.

The demand of growing children for protein is much higher than that of adults. If the supply is insufficient, it will affect the growth of tree height. In addition, collagen and mucin are also organic components of bones.

Recommended food: Chicken, beef, fish and shrimp, eggs, milk and tofu are all rich in protein.

▊ Focus 4: Iron, zinc and copper are indispensable.

Although the demand for them is not great, they are indispensable. If they disappear, the children will have all kinds of problems. Children with zinc deficiency have no appetite at all, which will inevitably affect their growth and development. Iron is an essential substance for synthesizing hemoglobin, and copper is a catalyst for synthesizing hemoglobin. If the supply of iron and copper in food is insufficient, it will inevitably hinder the synthesis of hemoglobin, and the growth and development, intellectual development and immune function will be affected, and children may often get sick. Recommended foods are foods rich in iron: viscera such as animal liver, beef and mutton, egg yolk, fish, adzuki beans and spinach.

Foods rich in zinc: oysters, animal livers.

Foods rich in copper: pig liver, pig blood, shrimp, crab and shellfish.

Point 5: Fresh fruits and vegetables

Fresh vegetables and fruits are rich in vitamins, which are necessary for human body. Vitamins A and C can make children have normal resistance. Recommended food

Vegetables: Chinese cabbage, carrots, cucumbers, green peppers, tender bamboo shoots, tomatoes and onions.

Fruits: oranges, bananas, pears, apples, grapes, peaches, apricots and watermelons.
