Abstract

Background: Heavy school bags increase students’ musculoskeletal disorders. According to instructions, weight of school bags should not exceed 10% of students’ body weight. This study aimed at investigating the ratio of school bags weight to students’ body weight and evaluating the prevalence of musculoskeletal disorders. Methods: In this cross-sectional study, 723 students were selected from six elementary schools in Kerman. Such information as the prevalence of musculoskeletal disorders and demographic characteristics were collected using a researcher-made questionnaire. Results: The highest prevalence of musculoskeletal disorders was related to shoulders, neck, and waist. Indeed, weight of 50.1% of students’ bags was over 10% of their body weight. The results showed a significant relationship between the prevalence of musculoskeletal disorders and school bags’ weight to students’ weight ratio (P = 0.03). Additionally, such disorders were significantly more frequent among students of higher grades. Conclusions: This study revealed a significant relationship between school bags’ weight and musculoskeletal disorders.

2014年伊朗克尔曼小学生书包重量及其与肌肉骨骼疾病的关系

背景：沉重的书包会增加学生的肌肉骨骼疾病。根据说明，书包的重量不应超过学生体重的10%。本研究旨在调查书包重量与学生体重的比例，并评估肌肉骨骼疾病的患病率。方法：在这项横断面研究中，723名学生来自克尔曼的六所小学。肌肉骨骼疾病的患病率和人口统计学特征等信息是使用研究人员制作的问卷收集的。结果：肌肉骨骼疾病的患病率最高的是肩部、颈部和腰部。事实上，50.1%的学生书包的重量超过了他们体重的10%。结果显示，肌肉骨骼疾病的患病率与书包的重量与学生的重量比之间存在显著关系（P=0.03）。此外，这种疾病在高年级学生中更为常见。结论：本研究揭示了书包重量与肌肉骨骼疾病之间的显著关系。
