Expert says weight should be 10% to 12% of child’s body mass
It is not easy to put together a student’s backpack:books, notebook, snacks, clothes. Only the basic items that students bring to school may already be of considerable importance to students, which can be harmful to children’s health. In order not to cause discomfort, according to pediatrician Marcelo Reibscheid, the ideal weight of backpacks should be between 10% and 12% of the body mass of each child.
– The weight varies according to each child. For example, if a student weighs 30 kg the backpack should have an equivalent weight, which would be between 3 kg to 3.6 kg.
Reibscheid says that backpacks should receive special attention from parents because with excessive weight pain and muscle contraction may appear in children and adolescents as time goes on.
– By forcing the muscles excessively can generate pains and problems in the column, like the lordosis and scoliosis. In some cases, even headaches and problems in the joints of the knee and hips.
One option can be adopted by parents and students: backpacks with wheels. In addition to being more advised and considered ideal by the pediatrician, they are not a preference among children.
But Reibscheid recalls: even though the backpacks are less harmful and require less body strength, they must also have proportional measures that correspond to each bone structure.
-The two casters should turn well on any type of floor. As the straps are retractable, they should be kept at waist height with a weight of up to 21% proportional to the student.
If the strap is below the waist, the student will maintain a slanted posture and will walk crookedly, which can lead to problems in the lumbar and back spine.
