Abstract：
The objective of this research was to analyze and elucidate the sagittal spinal posture status in older elementary school children, considering their gender and grade differences. The study involved 484 school children (252 males and 232 females) from grades V to VIII, assessed for sagittal spinal posture using the Formetric 4D System. The analysis, employing the Chi-squared test of independence along with the Z-test, did not reveal significant grade-related differences (p < 0.52) in the incidence of normal sagittal alignment or diagnosed outliers. However, within grade levels, no significant difference was observed for male participants (p < 0.80), while a significant difference was identified for females (p < 0.01). Examining gender differences across grades, a disparity was noted only among seventh graders concerning normal spine alignment and outlier existence (p < 0.01), favoring male participants. Regardless of the grade, a significant gender difference emerged in the location of diagnosed outliers: kyphosis (M = 108 vs. F = 72), lordosis (M = 5 vs. F = 14), kypholordosis (M = 18 vs. F = 66), and flatback outlier of the lumbar spine (M = 27 vs. F = 11). These findings suggest potential adjustments to the curriculum and highlight the need to tailor physical education instruction based on this study\'s outcomes. Consequently, these results imply the importance of a differentiated approach in preventing sagittal plane outliers of the spine in adolescent children.
摘要：
这项研究的目的是分析和阐明大龄小学儿童的矢状脊柱姿势状态，考虑到他们的性别和年级差异。该研究涉及从V到VIII年级的484名学童（252名男性和232名女性），使用Formetric4D系统评估矢状脊柱姿势。分析,采用卡方独立性检验和Z检验，在正常矢状面排列或诊断异常值的发生率方面,未发现显著的等级相关差异(p<0.52)。然而,在等级级别内，男性参与者没有观察到显著差异(p<0.80)，而女性差异显著(p<0.01)。检查不同年级的性别差异，仅在七年级学生中注意到有关正常脊柱对齐和离群值存在的差异（p<0.01），有利于男性参与者。无论等级如何,在诊断异常值的位置出现了显著的性别差异：后凸(M=108vs.F=72),脊柱前凸（M=5vs.F=14),金黄病（M=18vs.F=66),和腰椎的平背异常值(M=27vs.F=11)。这些发现表明了对课程的潜在调整，并强调了根据本研究结果定制体育教学的必要性。因此,这些结果暗示了在预防青春期儿童脊柱矢状面离群值的过程中,采用差异化方法的重要性.
