Every parent wants their child to have a strong and tall or beautiful and slender body. To achieve this wonderful expectation, as a parent, you need to understand some medical knowledge related to your child’s physical growth and development, and master some daily life skills that are beneficial to promote your child’s growth.
A. Factors affecting height
1, from the parents of genetic factors, genetic factors have a great impact on growth and development, but not unchangeable. According to research, 75% of the final height of the human body depends on genetic factors, that is, in general, “high plus high born high, high plus short born high, short plus short born short”, but the parents’ height is not the only factor affecting the height of their children, external factors, that is, the impact of environmental conditions on height should not be ignored. External factors mainly refer to nutrition, living habits, physical exercise, etc.
2, the impact of disease, such as liver and kidney insufficiency, will affect the conversion of growth hormone into growth hormone media, affecting the re-growth of height. Skeletal diseases of their own can also be detrimental to height, such as multiple epiphyseal chondrodysplasia, mucopolysaccharidosis, rickets, etc.
3, children’s own organism conditions lead to malnutrition and affect the development, the function of endocrine glands is particularly important, such as growth hormone, promote thyroxine, etc.. The lack of various nutrients, can not timely replenish the body’s metabolism necessary nutrients, the
So that the growth and development of the body is limited.
4, height and mental factors related. Studies have found that children who have been severely traumatized mentally have delayed or even stagnated growth. Such as by some kind of fright, learning burden is too heavy, parents divorce, etc. caused by excessive psychological pressure, because bad emotions will affect the function of the brain and endocrine system, the light affect the physical development, the heavy lead to a variety of diseases. Therefore, sadness and depression will not only make children and adolescents vulnerable to various diseases, but also affect growth and development, and even the phenomenon of “aging before aging”.
5, sleep has an impact on height, biologists research endocrine gland secretion law found that for children and adolescents, sleep well to grow taller. The growth of height depends on the continuous growth of the epiphysis, which is controlled by the endocrine glands. The main endocrine hormones that control height are growth hormone, luteinizing hormone and sex hormone secreted by the pituitary gland, among which growth hormone has the most significant effect. The secretion of growth hormone has its obvious regularity, that is, less secretion during the day and more secretion at night when sleeping.
6, height and sexual maturity early and late related, maturity age will affect the rapid growth of height, generally is the rapid growth phenomenon occurred earlier people, it is faster to reach the termination point; later occurred, also later to reach its end. While young girls with early sexual maturity stop growing taller, young girls with late sexual maturity are still growing taller. As a result, late sexual maturing girls are taller. The fastest growing period of height is the prepubertal period. In the year before the first menstruation of girls, the increase in height can reach 7 to 8 cm; while the peak of height growth of boys is the first year of puberty, about 13 to 14 years old, the height increase can reach 10 to 12 cm.
7, height and physical exercise related to the survey, a year of physical exercise can make boys’ height than the same age without exercise 1 to 2 cm longer, girls 2 to 3 cm longer. Elementary school students who exercise regularly are about 5 cm taller than those who do not exercise. Physical exercise can therefore promote the growth of the figure, one is to promote the secretion of growth hormone, the second is to strengthen the blood supply of bone cells, which is conducive to improving the proliferation of epiphyseal cartilage, and the third is to have a good stimulating effect on the proliferation of epiphyseal cartilage.
Second, what are the diets that affect the development of children
1, should not drink tea. Tea will affect the absorption of iron and calcium in milk, vegetables and other foods, causing a lack of the corresponding elements.
2, should not drink fruit dew. Because the fruit dew is artificially prepared, in addition to sugar, raffinate, saccharin and pigment.
3, should not eat more cold drinks. Eating cold drinks easily gastrointestinal dysfunction, leading to enteritis diarrhea, indigestion, affecting appetite.
4, the food should not be too salty. Too salty food to destroy appetite stimulate mucous membranes, but also can lead to high blood pressure in children and other diseases.
5, eat less sweets. Too much sweet food will affect appetite, leading to anorexia, in addition to affecting the body to absorb and use manganese, zinc, chromium and other trace elements and vitamin B ingredients, reducing the ability to resist disease, affecting growth and development.
Third, how to make children grow taller
To make children grow taller, parents are advised to pay attention to the following points.
1, adequate, varied and balanced nutritional diet, especially to properly supplement animal protein, in order to best protein bioavailability, can promote the absorption of trace elements zinc, iron and B vitamins, every night before bedtime to the child to drink the wai milk is very beneficial.
2, adhere to physical exercise, pay attention to the combination of work and rest, happy mood, is the catalyst for height growth. Specific physical exercise programs, such as pull-ups, playing basketball, volleyball, rope skipping, etc.
3, to ensure sufficient sleep, should not cause excessive fatigue of the body.
4.Create a harmonious, relaxed, comfortable and happy growing environment, including family environment and social environment.
5, seize the season of favorable impact on height, “the four seasons of the year is spring, everything grows by the sun” spring body growth is the fastest, because the spring wind and sunshine, spring flowers, everything grows season, this is the fastest growing plants in nature, and people are no exception.
6, seize the critical period of growth of adolescents, when the height of the fastest growth? Studies have confirmed that the majority of Chinese Han children’s height spike is around 12 years old for girls and 14 years old for boys; more than 90% of girls have the fastest height growth between the ages of 11 and 13, and boys between the ages of 13 and 15. In order to let children grow taller, parents should pay particular attention to children in the rapid growth period of nutrition, exercise and other issues.
Should focus on nutritional supplements Nutrition is the key to children’s physical growth. A person’s height, weight and function depend not only on the teenage development period, but also on the good or bad situation of the youth development period.
Scientific research proves that the human body enters puberty height grows significantly, can grow 11 – 15 cm per year, boys can grow to 25 years old, girls can grow to 23 years old, human height depends on the growth of bones, human vertebrae play a major role, growth and development is a key factor in determining the height, lower limb bones grow fast, but slowly stop after puberty, while the vertebrae still continue to grow, until The growth of the lower limb bones is fast but stops slowly after puberty, while the vertebrae continue to grow until youth, and will stop only after 25 years old.
Several methods to predict the height of children in adulthood
1.Male height = length at birth (cm) ÷ 0.2949;
Female height = length at birth (cm) ÷ 0.3109.
Note with this formula: only applicable to normal full-term newborns; measurement of length data such as accurate to 0.1 cm, height prediction will be more accurate.
2. Male height = height at 3 years old × 0.545 + average height of parents × 0.544 + 37.69 (cm);
Female height = height at age 3 × 0.545 + average parental height × 0.544 + 25.63 (cm).
3, human standard height prediction formula (genetic law)
Male height = (father’s height + mother’s height) × 1.08 ÷ 2 (cm)
Female height = (father’s height × 0.923 + mother’s height) ÷ 2 (cm)
