Health experts warn of risks from heavy school backpacks

Health experts and medical institutions are issuing guidance for the back-to-school season to prevent spinal and muscular injuries in children caused by excessively heavy backpacks.

In Mexico, the Instituto Mexicano del Seguro Social (IMSS) and the American Academy of Pediatrics recommend that a student's backpack should not exceed 10% to 15% of their total body weight. Specialists warn that improper weight distribution or excessive loads can lead to chronic pain in the back, neck, and shoulders, as well as postural alterations during critical growth stages.

In Canada, the Association chiropratique du Québec suggests a five-point check for backpack suitability, emphasizing that bags should be properly sized, feature wide padded straps, and include chest or waist straps for stability. In France, the Fédération nationale des conseils de parents d’élèves (FCPE) notes that while digital tools have reduced physical load, maintaining a weight limit of approximately 10% of a child's weight remains a public health priority. Experts advise using lightweight materials and teaching children proper lifting techniques, such as bending at the knees rather than the waist.
