The weight of schoolbags and the prevalence of musculoskeletal symptoms amongst 140 students (70 third form students comprising 35 females and 35 males, and 70 sixth form students comprising 35 females and 35 males) from five New Zealand secondary schools was investigated. Schoolbag weight for third form students (mean age 13.6 years) was 13.2% of their body weight, while for sixth form students (mean age 17.1 years) it was 10.3% of their body weight. These weights may exceed the recommended guideline load limits for adult industrial workers. Musculoskeletal symptoms were reported by 77.1% of the students. Symptoms were most prevalent in the neck, shoulders, upper back and lower back. Although musculoskeletal symptoms are believed to be multifactorial in origin, the carriage of heavy schoolbags is a suspected contributory factor and may represent an overlooked daily physical stress for New Zealand secondary school students.
对来自新西兰五所中学的140名学生（70名初三学生，包括35名女生和35名男生，以及70名高三学生，包括35名女生和35名男生）的书包重量和肌肉骨骼症状的患病率进行了调查。初三学生（平均年龄13.6岁）的书包重量占其体重的13.2%，而高三学生（平均年龄17.1岁）的书包重量占其体重的10.3%。这些重量可能超过了成年产业工人推荐的负荷限制指南。77.1%的学生报告有肌肉骨骼症状。症状在颈部、肩部、上背部和下背部最为普遍。尽管肌肉骨骼症状被认为是多因素起源的，但背着沉重的书包是一个疑似促成因素，可能是新西兰中学生日常身体压力中一个被忽视的因素。
