In addition to the effects of congenital factors, gene mutations and diseases, nutrition, sleep, exercise and other acquired factors also play a vital role in height. Experts remind that parents should pay attention to the influence of these acquired factors on children's height and help children grow taller through scientific methods. With the arrival of spring, children's outdoor activities increased, bathed in the beautiful spring light, and their bodies began to "draw sticks". In spring, when everything grows, many parents are particularly concerned about their children's height development. So, what factors are related to height? What should parents do to help their children grow taller? Let's take a look at the answers and suggestions given by experts. Yan Jie, director of the Clinical Nutrition Department of Beijing Children's Hospital affiliated to Capital Medical University, told Sci-Tech Daily that children should pay special attention to two key age groups when growing tall, one is the rapid growth period from birth to 2 years old, and the other is adolescence. "Children aged 0-1 will grow at least 25 cm, and children aged 1-2 will grow 10-15 cm. Scientific feeding can ensure the normal development of children during the rapid growth period from birth to 2 years old." Yan Jie said that if the feeding is improper or the infants often get sick, their height will also be adversely affected. It is worth noting that the height lost during this period is not easy to remedy. How to feed infants scientifically? Yan Jie suggested that parents should pay attention to the "China Infant Feeding Guide (2022)". She said that according to different ages, the guide is divided into three parts: "Breastfeeding guide for 0-6 month-old infants", "Feeding guide for 7-24 month-old infants" and "Dietary guide for pre-school children", which put forward clear guidelines. For example, for infants aged 0-6 months, breast milk is the most ideal food. We should stick to pure breast milk feeding until the infant reaches 6 months of age and properly supplement vitamin D for the infant. The length, weight and head circumference of infants within 6 months of age should be measured once a month. "Adolescence is the second peak of height growth. Generally speaking, from the beginning of sexual development to the end of growth, the height of boys will increase by 25-28 cm, and girls will increase by about 25 cm," Yan Jie said. She said that puberty can be divided into early, middle and late stages, lasting about 1 year, 2 years and 2-3 years respectively. The early adolescence of girls occurs at the age of 9-11, and that of boys occurs at the age of 11-13. Children begin to grow rapidly in the middle of adolescence, while the secondary sexual characteristics gradually appear. The height of children increases slowly in the late adolescence. Menarche is a sign that girls end in the middle of adolescence and enter the late adolescence, while boys are marked by ejaculation. At menarche, the height growth of girls has reached 95% of the final height, and then enters the growth decay stage. Generally, the height can increase from 3 to 11 cm, which is similar to boys and girls. Yan Jie reminded that if parents find that the height of a child after menarche or ejaculation is significantly different from that of children of the same age and the height speculated by heredity (slightly short), they should go to the hospital to consult experts in time, and do not mistake it for "late growth" and miss the opportunity for height development of the child. Pay attention to nutrition, sleep, exercise and physical and mental health. Height is the key of heredity, birth weight, length, nutrition in later stage, whether there is disease, and various hormones in the body
