"Schoolbags with multiple functional bags, large volume capacity, and spinal function are the most popular among parents
The reporter experienced one of the best-selling spine protection backpacks, with a wide shoulder strap and an S-curve. The salesperson explained, "This scattered bag conforms to the human body structure and is not easy to slip off." The main bag of the backpack has a mesh half compartment to separate textbooks and homework books, and there is also a small pocket for scattered items. There are two mesh side pockets on both sides of the backpack, which can hold umbrellas and water cups. The back is made of breathable mesh fabric, which will not feel stuffy when used.
In addition to the regular backpack, there is also a type of lever backpack that is favored by some parents. Ms. Cui, a parent, said, "When I see a backpack with a lever, I think it's not bad. It's like when adults go on a trip and carry backpacks for a long time, they still feel uncomfortable. With a lever, it's much easier." With the addition of a lever and a roller, the weight of a backpack cannot be underestimated. The reporter picked up a backpack casually and felt that it was a bit difficult to carry with one hand. After weighing, the backpack weighed 2.5 kilograms. An aunt Li said, "A backpack with a lever can be used on flat ground, but it's too heavy to go up and down stairs
Du Jianwei, Deputy Chief Physician of the Orthopedics Department at Yangzhou University Affiliated Hospital, suggests that "the impact of backpacks on the development of children's spine largely depends on the weight and duration of the book. It is recommended to use a backpack for long-term carrying. If the book is heavy, it is recommended to use a backpack with a backpack design. The least impact on the spine is a lever backpack, but it is important not to drag it with one hand for a long time
Buying a backpack guide
In 2018, the National Health Commission issued the recommended health industry standard "Hygienic Requirements for Primary and Secondary School Students' Schoolbags", which stipulated that good backpacks should meet six standards. Parents who are preparing to buy backpacks, remember to compare them!
1. The weight of the backpack shall not exceed 10% of the body weight
When choosing a backpack, it is recommended that the self weight of the backpack should not exceed 1 kilogram, and the total weight should not exceed 10% of the child's weight. Research has shown that when the back is overloaded, it may lead to lower back pain and even abnormal posture, and overweight backpacks can easily cause instability of the center of gravity when walking.
2. Consider using a small backpack
Children of different ages are suitable for backpacks of different sizes, and the area of the backpack attached to the child's back should not exceed 3/4 to prevent "inadequate backpacks".
3. It's best to buy a backpack
Carrying a shoulder bag for a long time can cause pain in mild cases and scoliosis in severe cases, affecting growth and development. It is best for parents to choose backpacks for their children, and it is best to choose a wide shoulder strap, which can effectively disperse the weight of the backpack and reduce shoulder pressure.
4. Equipped with reflective materials
At least 20mm wide reflective material should be equipped on the front and side of the backpack, and shoulder straps should be equipped with at least 20mm wide and 50mm long reflective material. The reflective material on the backpack can make it easier for students walking on the road to be recognized, serving as a reminder and warning for passing vehicles.
5. The back and bottom of the backpack should have support functions
The main purpose is to help children reduce their burden and provide protection for their back.
6. No odor
The formaldehyde content should not exceed 300 mg/kg, and the maximum safety limit for lead is 90 mg/kg. If the backpack has a severe pungent odor, it may be an unqualified product and may pose a threat to the child's health.
