Researchers identify maximum weight children should carry in school backpacks
Researchers have determined for the first time the maximum weight a child should carry using a school backpack trolley: a maximum of 20% of their body weight.
To date, weight recommendations have been established for ordinary school backpacks, as they are the most widely used type in the school context worldwide. However, some children use backpacks on wheeled trolleys, and until now there have been no studies making weight recommendations for this type of backpack.
