BACKGROUND
Young students with skeletal immaturity report an increasing number of musculoskeletal symptoms associated with daily use of heavy backpacks. This cross-sectional study investigated the relationship between heavy backpack use and reports of pain.
METHODS
Data were collected from 300 students aged 11 to 18 at the University of Toronto Schools.
RESULTS
Students, on average, carried 15.9% of their body weight. 54% of students reported physiological complaints, primarily back, shoulder, neck, and leg pain. Backpack weight as a % of body weight was strongly associated with pain complaints. Younger students and those with longer commutes were more likely to report heavy backpacks (50% compared to 22.6% of older students, p< .001) and pain.
CONCLUSION
Carrying heavy backpacks could result in increased musculoskeletal complaints in young students. Findings suggest that even the upper bound of currently recommended guidelines (20% of body weight) may be too high, especially for younger children.
背景
骨骼未成熟的年轻学生报告称，与日常使用沉重背包相关的肌肉骨骼症状越来越多。这项横断面研究调查了沉重背包使用与疼痛报告之间的关系。
方法
从多伦多大学附属学校的300名11至18岁学生中收集数据。
结果
学生平均背负的重量为其体重的15.9%。54%的学生报告有身体不适，主要是背部、肩部、颈部和腿部疼痛。背包重量占体重的百分比与疼痛投诉密切相关。年龄较小的学生和通勤时间较长的学生更有可能报告背负沉重背包（50%，而年龄较大的学生为22.6%，p<0.001）和疼痛。
结论
背负沉重背包可能会导致年轻学生的肌肉骨骼不适增加。研究结果表明，即使是目前推荐指南的上限（体重的20%）可能也过高，尤其是对年幼的儿童而言。
