To examine the epidemiologic, physiologic, and biomechanical literature that has contributed to the suggested weight limit of 10 to 15% body weight for children’s backpacks.
The majority of children use a backpack to transport their belongings to and from school on a daily basis; however, controversy exists over the safety of backpack use and backpack loads.
A thorough review of the literature was completed to examine the appropriateness of the suggested weight limits and to determine future areas of research needed to increase the safety of children’s backpacks.
Epidemiologic, physiologic, and biomechanical data support the suggested weight limit of 10% to 15% body weight.
Based on the current literature, the value of 10% to 15% body weight is a justified weight limit; however, further research is required to determine the association between backpack use and injury and how the factors of load, backpack design, and personal characteristics, such as physical fitness, interact and influence the adaptations required when carrying a backpack.
Weight limits have been recommended by various health organizations to make backpack use safer. This paper examines the epidemiologic, physiologic, and biomechanical literature contributing to these recommendations and examines other requirements to increase the safety of these devices.
