Association Between the Weight of Schoolbags & LBP in Schoolchildren
- RRS Education
As a profession, we’ve generally assumed that carrying a heavier backpack (> 10% of a child’s bodyweight) may contribute to low back pain in school children. What does the evidence tell us?
While predominantly thought of as a condition affecting adults, low back pain (LBP) among school-aged children is, in fact, higher than previously thought, with a lifetime prevalence of 47% by age 14. Additionally, adolescent LBP is a risk factor for LBP in adulthood. The causes of adolescent LBP are multifactorial and include biological, psychosocial and lifestyle-related variables. One causal factor that warrants investigation is the weight of schoolbags that children carry to school. Indeed, over 80% of schoolchildren reporting LBP attribute their pain to heavy schoolbags.
The goal of this study was to estimate whether carrying a schoolbag heavier than advised (i.e. > 10% of bodyweight) is associated with a higher prevalence of LBP in children between the ages 9 and 16. The authors performed a systematic review of the literature and a meta-analysis of available data, including an individual participant data (IPD) analysis...the results may surprise you!
