From the characteristics of growth and development, children's height growth is seen
Normal growth and development in children
"Small Body, Big Secret"
The law of height growth
When height no longer grows
Increased secretion of sex hormones, which have a two-way effect on the growth-promoting effect of puberty
1. Promote the proliferation of chondrocytes in the epiphyseal cartilage growth plate and prolong the bones, so as to reach the effect of pro-growth
2. While promoting cell proliferation, the cartilage differentiation and proliferation capacity is accelerated, and bone aging eventually closes the epiphyseum, and the height will no longer grow. The bone age of boys is closed at 16 years, and the bone age of girls is closed at 14 years.
Start by recognizing "short stature" and look at the situation of your own children
Definition of dwarf
Childhood short stature is when a child's height is two standard deviations below the average height of children of the same sex, age, or race, or below the third percentile, with an annual growth rate of less than 5 centimeters. suggestion:
Simply put, in a similar living environment, 100 children of the same race, gender, and age are randomly selected; the shortest 3 are considered short in line according to the size of the queue.
List of causes of short stature in children
The situation of the dwarfness of the continent is not optimistic
Awareness is low
Parents lack understanding, do not know that the child's short stature is a disease, do not know that the grass-roots doctors who can be treated lack knowledge of diagnosis and treatment, and cannot diagnose and effectively refer
Low attendance
About 7 million people aged 4-15 need treatment, but less than 300,000 children are treated each year
Treatment rates are low
Really get the treatment
Treatment is irregular
Late treatment, insufficient or overdose, short course of treatment, light monitoring, etc
The harm of being short
Employment pressures
Civil service examinations (public security, procuratorial, legal and other departments), enlistment in the army, flight attendants, etc
Height requirement: Male: 170cm or above Female: 160cm or above
Academic pressure
Some art colleges, military academies, public security colleges, sports colleges, and flight attendant majors
Emotional stress
According to a small sample survey by the National Dwarf Association, 72% of short people patients have only junior high school education and below, 68% of the population does not have a decent and stable job, and the marriage rate of adult short people patients is only 15%.
The little god hurts, who can solve it?
More than 90% of children with short stature will have psychological disorders of inferiority and depression, in fact, compared with normal children, although their intelligence is within the normal range, their hearts and emotions are very unstable, and they will even refuse to socialize!
How do parents monitor their child's growth and development?
Early detection: regular physical examinations, height measurement
1. The principle of height measurement
At the same time, the same person, the same ruler
2. Measurement of height
Choose a wall without skirting board at home, paste a height ruler, generally recommend regularly measuring the height of children every three months, pay attention to slippers when measuring height, pillow, hips and heels are close to the ruler board, both heels are close together, the tip of the feet is 45 degrees, and the eyes are level ahead.
3. Make a good height record
Compare the height graph and growth rate table to find out in time that children have growth backwardness.
Criteria for judging short stature:
China's 0-18-year-old children and adolescents are of high standard
The number of references < 2SD
Parents of children in the red box should pay attention! Your child is already in the range of short stature!
Growth curve
Early diagnosis: Go to the hospital for examination
Control criteria, diagnosis of short stature;
Check bone age and assess growth potential (how tall your child can grow, not depending on age, depends on bone age)
Imaging (ultrasound, MRI) tests, blood draws for biochemical, nutrient determination
Individuals require genetic tests such as chromosomes
Early treatment
Nutritional therapy
Balanced protein-rich diet; intensive formula
Vitamin D, calcium, amino acids, lysine
Treatment of the underlying disease
Malnutrition, recurrent diarrhea, respiratory infections, congenital heart disease
Other endocrine diseases
Advantages of early treatment
Effective
The younger the age, the more active the cartilage layer hyperplasia and differentiation of the epiphysis, the greater the bone growth potential of the child, and the more sensitive the response to treatment, the better the effect
Low cost
The younger the child, the lighter the weight, the smaller the dose of the drug used and the less cost it will be
Nutrients that are closely related to height growth
Tips:
It is not advisable to overeat and maintain a moderate hunger pang conducive to the secretion of growth hormone
Suitable for exercise
Get enough sleep
Length of sleep
1
8 hours for middle school students; 9 hours for elementary school students
2
Preschoolers 9-10 hours
3
Infants 11-15 hours; infants 16-18 hours
Consider individual differences; Nighttime sleep is more important; (10 p.m. - 2 a.m. is the peak period of human growth hormone secretion)
Pleasant mood
Feel good
Facilitates the secretion of growth hormone
Promotes nutrient absorption
Improves sleep quality
Upset
Affects height growth
Loss of appetite, decreased digestion and absorption capacity
The body's resistance is reduced and it is susceptible to disease
