Spring is an important period for children's growth and development, and it is also the golden period for children's physical development.
The World Health Organization (WHO) has confirmed that there is a significant seasonality in children's growth and development, with spring (March to May) growing the fastest, 2-2.5 times that of autumn.
Therefore, scientifically grasping the critical period of spring growth is very important for children's physical development.
The genetic factor of a child's height accounts for 60%~70%, which determines the growth potential of height. The acquired intervention in the three critical periods of growth and development can determine whether the child can successfully realize these potentials, or even exceed them.
1. Three critical periods of growth and development
1. 4-6 years old
Growth hormone and thyroxine have been basically formed in the body, and diet and sleep habits have gradually formed, and the epiphyseal cartilage layer proliferation and differentiation are more active during this period, and the response to treatment is also sensitive. It is the most critical period for the diagnosis and treatment of short stature. It is necessary to judge whether the child's height is up to the standard in time.
2. Pre-pubertal around 8 years old
Before the sexual development period, it is necessary to judge whether the child's growth and development are normal, whether the height is up to the standard, and whether there are signs of precocious puberty.
3. Youth
It's the final sprint to grow taller. The first menarche of a girl and the change of voice of a boy indicate that the growth of the human body is about to end. Intervention at this point is unlikely to be effective.
Second, the spring boosts the strategy
1. Season
Children's growth and development are significantly affected by the seasons. In spring, the baby's metabolism is vigorous, and the secretion of endocrine hormones (especially growth hormone) increases, which is the highest peak of the year, and the growth rate is 2-2.5 times that of autumn.
It is necessary to seize the good time of spring to grow taller and let children bask in the sun more. Helps in the synthesis of vitamin D in the body and provides sufficient calcium and phosphorus for bone growth.
2. Sleep
The secretion of growth hormone is pulsed, and the frequency of secretion at night is higher than that during the day, and the amount secreted is about 3 times that of the awake state during the day. Especially about 1 hour after entering deep sleep, the secretion of growth hormone is the most vigorous, and 10 o'clock in the evening to 2 o'clock in the morning is the peak period of growth hormone secretion, which is 1/2-3/4 of the secretion amount throughout the day.
Therefore, if you want your child to grow taller, you must ensure adequate and high-quality sleep, and it is recommended to go to bed before 10 o'clock.
3. Exercise
Exercise stimulates the secretion of growth hormone. Growth hormone secretion is most vigorous after 30 minutes of exercise. When children run, jump, etc., they will pull the joints, so that the long bones of the body are stressed, stimulate the development of cartilage at both ends of the bones, and also help the bone calcium and phosphorus metabolism, accelerate the bone deposition of minerals, so that the bone density increases, and the bones become thick and solid.
It is recommended to maintain 30 minutes of exercise every day, such as playing basketball, swimming, skipping rope, touching high jumps and other longitudinal exercises, to carry out benign mechanical stimulation of bones, so that their value-added ability can be strengthened, and the growth rate of bones can be accelerated.
4. Nutrition
Avoid giving children foods containing hormones, such as animal colostrum, pollen, honey, royal jelly, chicken embryos, artificially raised with hormones, ripening soft-shelled turtles, yellow eels and out-of-season fruits and vegetables, etc., so as to avoid premature sexual development of children, early closure of epiphysis, and lifelong high.
For the intake of high-quality protein and calcium, it is recommended to have 300-500mL of milk and one egg per day. Eat more fruits and vegetables in season, balance nutrition, eat reasonably, and not be picky.
3. Tips
Intrauterine growth retardation is indicated if the child is born less than 47 cm in length, less than 7 cm per year before the age of 3 years, less than 5 cm per year until the age of 3 years, and less than 6 cm per year after puberty. At the same time, we should pay attention to the role of weight in the process of height and growth and development, prevent overweight and obesity, and do a good job in weight management.
The growth and development clinic of Yiyang Maternal and Child Health Hospital reminds you that if you find abnormal growth and development of your child, you should see a doctor in time to find out the cause and intervene or treat it as soon as possible.
