Sagittal spine curvature deformities are common among elementary school students due to long malposition and lack of physical activity.
This study aims to compare sagittal spine deformities among first graders (young and elder school students) in elementary schools.
The sagittal spinal curvatures of 45 young school students aged 5-7 years and 50 elder school students aged 9-11 years were examined by using spinal mouse device.
Independent sample t-test shows statistically significant differences in sagittal spinal deformities with increased thoracic kyphosis and spinal flexion in young children than elder children (P = .000, t = 10.72). However, young children show lesser lordosis than elder children (P = .001, t = -4.47). In addition, the young children established a higher significant coefficient of compensation (CC) than elder children (P = .000 t = 12.58).
The results suggest that the forward flexion of the trunk is more common among young children than elder children. This may be attributed to differences in postural awareness and way of sitting among students of elementary school. So, it is recommended to encourage the proper postures among students of first graders especially young children.
由于长期姿势不良和缺乏体育活动，矢状面脊柱弯曲畸形在小学生中很常见。
本研究旨在比较小学一年级学生（低年级和高年级学生）的矢状面脊柱畸形情况。
使用脊柱鼠标设备对45名5至7岁的低年级学生和50名9至11岁的高年级学生的矢状面脊柱弯曲情况进行检查。
独立样本t检验显示，低年级儿童的矢状面脊柱畸形与高年级儿童相比，胸椎后凸增加和脊柱前屈有统计学显著差异（P = .000，t = 10.72）。然而，低年级儿童的腰椎前凸比高年级儿童小（P = .001，t = -4.47）。此外，低年级儿童建立的代偿系数（CC）比高年级儿童更高（P = .000，t = 12.58）。
结果表明，躯干前屈在低年级儿童中比高年级儿童更常见。这可能归因于小学生在姿势意识和坐姿方式上的差异。因此，建议鼓励一年级学生尤其是低年级儿童保持正确姿势。
