In 163 Viennese pupils in standard 1 to 8, the weight of the schoolbag, the bodyweight and the ratio of these two parameters were examined in order to describe the amount of burden carried by those children. The results were: 1. The weight of the schoolbag war 4.0 kg (range 1 to 9 kg). 2. The pupils carried a schoolbag weighing on the average 10%, in standard 2 about 15% and in standard 8 about 6% of their bodyweight. 3. In every 6th pupil, the weight of the schoolbag constituted more than 15% of the bodyweight. 4. In analogy to pupils in standard 2, adults with a body weight of 70 kg would have to carry a weight of up to 17.5 kg to their working place. 5. While pupils have to carry a burden between 10 and 25% of their bodyweight, adults were carrying only between 1 and 10% of their bodyweight to work. We conclude that pupils are carrying daily a heavy burden in form of a schoolbag and adults apparently don't care about it.

Faculty of medecine in Tunis, University Tunis El Manar, Tunis, Tunisia.
Background: The prevalence of back and neck pain is common in children and adolescents, and in some series the numbers are alarming. Various risk factors have been identified, although some are controversial.
Objective: To determine the prevalence of neck and back pain in children and adolescents and to investigate the potential association with various risk factors identified in the literature.
Background Schoolbags or backpacks have been an essential part of the education system for a long time. However, a hefty backpack causes the child to arch the back excessively or bend their head and trunk forward to withstand the weight of the schoolbag. If the student carries the backpack on one shoulder, he/she bends to the opposite side to compensate for the extra weight, which may damage the shoulders and spine.

Background: Unsuitable schoolbags may stress the spine and promote poor body posture, particularly for school students. Global recommendations have suggested that schoolbag weight must not exceed 10% of a healthy student's body mass, which would need continuous monitoring and enforcement.
Objectives: The present study presents a comparison between an ergonomically designed schoolbag, which helps reduce the potential effects of carrying a load, and a commercial one.
