”Children’s height is 70-80% determined by genetic factors, 20%-30% by acquired factors, including nutrition, exercise, sleep, disease, etc.” By enhancing nutrition, more exercise, to ensure good sleep, children can completely and time to “grab height”. Formula to estimate the future height of children Parents want their children to be ‘taller’, most parents are actually just too sensitive to their children’s height, many children are short compared to their peers, but not dwarfism. Parents can estimate how tall their children can grow in the future by using a simple formula: Genetic height for boys = (father’s height + mother’s height)/2 + 162.5px, and genetic height for girls = (father’s height + mother’s height)/2 – 162.5px. “At this point, the calculated The value is an average value, about 70-80% of people’s height will be around this average”, but each child has 5-8 cm of room to grow taller, how to fight for these precious centimeters, need parents to understand the knowledge of their children’s growth and development at all ages. So, what kind of height is considered short? “Slowed growth is often one of the early signs of childhood illness.” “Normal children grow at different rates at different times. Usually, if a child is less than 50 cm long at birth, grows less than 7 cm per year for children under 2 years old, less than 5 cm per year for children between 4 years old and puberty, and less than 6 cm per year for children during puberty, it is considered a slowed growth rate and needs to be seen by a pediatric endocrinologist in a timely manner. “ The “method” of growth is to move and to have the “method” to exclude the disease factor of short, and to teach some “growth” tips. ”Growth hormone is the most important growth-promoting hormone in the human body, and this hormone can make people grow taller by increasing the secretion of growth hormone through exercise.” At the same time, the secretion of growth hormone has a distinct circadian rhythm, with a high peak at night. In particular, the peak secretion is around 9 p.m. until 2 a.m. Therefore, she recommends that children should preferably go to bed at around 9 p.m. “If a child can insist on going to bed around 9 pm every day, it will definitely help a lot in growing, on the contrary if a child goes to bed at 12 pm every day, then it will definitely affect the growth”. ”In addition, do more jumping rope, playing basketball, badminton and other sports with upward body and more limb movement, also conducive to growth.” Jumping rope is the most conducive to growth, usually heartbeat in 120 ~ 140 times / min, is a kind of aerobic exercise, if you adhere to jump rope 1000-2000 every day, most children will significantly increase the growth rate.” Bone age measurement to prevent dwarfism In addition to height, bone age largely represents the true level of development. However, bone age and age are not necessarily in sync. The difference between the two within one year is considered normal development; those older than one year are premature; those younger than one year are late. In general, the epiphysis is mostly close to closing at the age of 14 for women and 16 for men, so the chance of growing taller is very small.
