This review included 69 longitudinal and cross-sectional studies, with a total of 72,627 children and adolescents. The analysed outcomes included the number of back pain episodes, number of care-seeking episodes and school absence due to back pain.
Risk of study bias was assessed using a modified version of the Quality in Prognosis Studies (QUIPS) tool. The analysed studies had a moderate to high risk of bias, and pooling was not possible due to study heterogeneity in terms of exposure variables, measurement instruments and data collection methods.
However, the volume of research and the lack of any type of association between schoolbag use and back pain suggest that resources dedicated to the prevention of back pain in children and adolescents are better spent elsewhere.
These findings have important implications in terms of education regarding backpack recommendations and advising parents based on accurate scientific evidence, free from unsubstantiated claims and financial interests.
