Health experts and educators continue to emphasize the importance of ergonomic backpack use to protect children’s musculoskeletal health. While previous guidance suggested weight limits of 10–20% of body weight, the American Academy of Pediatrics (AAP) notes that the commonly cited 10–15% guideline lacks solid evidence. Instead, experts recommend keeping loads as light as possible to avoid strain. New research from Saarbrücken University, known as “Kidcheck,” provides further nuance. The study of 60 primary school students indicated that backpacks weighing up to 20% of a child's body weight did not cause significant changes to the muscular or skeletal systems. However, researchers observed that noticeable issues in the abdominal and waist muscles began to emerge when weight reached approximately 30% of the child's body weight. Medical specialists have issued further warnings regarding the risks of excessive weight, noting it can lead to hunching, neck and shoulder pain, muscle fatigue, and spasms. To mitigate these risks, some experts suggest a stricter limit, stating a bag should not exceed 10% of a child's body weight, with 15% serving as the “absolute upper limit.” To maintain proper posture, parents are advised to remove unnecessary items like toys and ensure the bag sits close to the back without hanging below the waist.
