The aim of the paper was to determine a correlation between the weight of a child's backpack, their body weight, and certain features of their body posture.
The study group consisted of 109 children, all aged seven years. The parameters of body posture were determined using the Zebris Ultrasonic System.
The number of children carrying a school backpack in accordance with recommendations was 44 subjects (40.37%). Statistically significant changes were found in the total length of the spine (Z = 2.223, p = 0.026) and between backpack weight and changes in the following parameters: the total length of the spine (rs = -0.3999, p = 0.017), the length and the angle of the lumbar lordosis (rs = -0.3352, p = 0.049), the angle of the lumbar lordosis (rs = -0.5065, p = 0.002), and the sacral angle (rs = -0.4279, p = 0.010).
Wearing a backpack heavier than 10% of one's body weight can cause shallowing of the lumbar lordosis and a tendency towards a vertical position of the sacrum. Monitoring the weight of children's school backpacks and enabling them to leave books and notebooks at school would probably be beneficial in reducing the daily burden put on children's spines.
本文的目的是确定儿童背包重量、体重与身体姿势的某些特征之间的相关性。
研究组由109名7岁儿童组成。使用Zebris超声系统确定身体姿势参数。
按照建议背着书包的儿童数量为44名（40.37%）。在脊柱总长度方面发现了具有统计学意义的变化（Z = 2.223，p = 0.026），并且在背包重量与以下参数变化之间：脊柱总长度（rs = -0.3999，p = 0.017）、腰椎前凸的长度和角度（rs = -0.3352，p = 0.049）、腰椎前凸角度（rs = -0.5065，p = 0.002）以及骶骨角度（rs = -0.4279，p = 0.010）。
背着超过自身体重10%的背包会导致腰椎前凸变浅以及骶骨趋于垂直的倾向。监测儿童书包的重量并允许他们将书籍和笔记本留在学校，可能有助于减轻儿童脊柱的日常负担。
