Regarding whether schoolbags have an impact on the development of primary school students, Liu Ning, director of the Sports Medicine Department of Zhengzhou Orthopedic Hospital, said: Teenagers are in the stage of growth and development, and their spines are not fully developed. If they carry heavy schoolbags for a long time, it will have a serious impact on their spinal development, and it is likely to cause corresponding spinal deformity, thus affecting their height development.

Director Liu further said that the schoolbags carried by children are mostly "shoulders" and "one shoulder". If the "shoulders" are too heavy, it is easy for children to lean forward when carrying schoolbags. In this way, the child's spine will naturally bend forward, affecting the child's body shape. Especially for those children who usually have little exercise and lack calcium, overweight schoolbags will lead to chest deformity or hunchback, which will destroy the normal curve of the body. The "one-shoulder" schoolbag is more harmful to children and will cause scoliosis. Once the deformity occurs, it will gradually develop and require special correction or surgery to return to normal.

Reducing the burden of schoolbags is beneficial to children's growth.

Suggestion 1: Pay attention to the weight of the schoolbag.

How to avoid the unhealthy influence on children's spinal development? Director Liu said, first of all, it is necessary to "reduce the burden" on children's schoolbags. It is best for children in Grade One and Grade Two to control the weight of schoolbags below 1.5 kg, and senior pupils should carry schoolbags of about 2.5 kg. Secondly, try not to use a one-shouldered schoolbag; Thirdly, in addition to physical education class at school, primary school students should also pay attention to exercise at home, and parents should take their children to participate in outdoor activities.

For the tie-rod schoolbag mentioned at the beginning of this article, Director Liu thinks it is not the best choice, because children often pull schoolbags with one hand, and the stress position of the spine is on the side, which is also easy to cause scoliosis. "It is still necessary to reduce the burden on the child's schoolbag."

Suggestion 2: Books should be put in the desk.

Wang Haiyong's suggestion is that parents should change their "education view" into "education view" and pay attention to the cultivation of children's good behavior habits and quality; As a school, we should strive to improve teachers' quality, improve teaching methods and teacher evaluation system, and pay more attention to children's personality cultivation and healthy growth; If the school can add a drawer with a lock to students' desks, students only need to bring a few review textbooks and homework for the evening when they go home every day, and the rest can be neatly placed in the desk drawer, which can not only keep the textbooks and homework neat, but also make students not forget in class.

Recommendation 3: Teach children to pack their schoolbags.

In addition, parents are reminded to buy light schoolbags for their children as much as possible, instead of focusing only on fancy forms and not on weight.

At the same time, many children's schoolbags are arranged by themselves. In order to save trouble, the children put all the books in and have to carry heavy schoolbags every day. In fact, some of their books were not needed at all in the study that day. If parents can take a few minutes to teach their children to pack their schoolbags and bring books as needed according to the needs of their children's courses that day, their children will go into battle lightly and come back easily every day.
