Appropriate arrangement of classroom ergonomics is necessary for maintaining health and improving academic performance, learning, and motivation.
We aimed to determine the anthropometric measurements and ergonomic risk levels of students during a handwriting activity on a fixed desk and chair and to analyze the mismatch and relationships between these factors.
This study included 149 university students (female:73, male:76). Anthropometric measurements (lower and upper extremity length, shoulder height, elbow-rest height, hip-popliteal length, popliteal height, knee height, the distance between tragus and wall, and between acromion and wall) were done with a tape measure. The Rapid Upper Limb Assessment (RULA) tool was conducted to determine the ergonomic risk level while students wrote a standard text on a fixed desk and chair as if they were taking notes in the classroom. The mismatch was evaluated between backrest height and sitting shoulder height, seat height, and popliteal height. The Pearson Chi-Square and the Spearman Correlation test were used for statistical analysis.
The median values of the participants' age, height, weight, and BMI were 22 years, 1.70 m, 68 kg, and 23.18 kg/cm2, respectively. Most students had inadequate ergonomic posture while writing on fixed furniture at the university (Median RULA grand score: 4). More mismatches for seat height (54.4%) were found in high ergonomic risk levels but mismatches for backrest height did not follow a similar result.
More investigation should be conducted with prospective studies including interventions like adjustable furniture.
为了维护健康、提高学习成绩和学习积极性，适当安排教室人体工程学十分必要。
我们旨在确定学生在固定桌椅上进行书写活动时的人体测量学测量值和人体工程学风险水平，并分析这些因素之间的不匹配和关系。
本研究纳入了 149 名大学生（女性 73 名，男性 76 名）。使用卷尺进行人体测量学测量（下肢和上肢长度、肩高、肘托高度、髋-腘长度、腘高、膝高、耳屏与墙壁之间的距离以及肩峰与墙壁之间的距离）。当学生们在固定的桌椅上书写标准文本时，就像在教室里做笔记一样，使用 Rapid Upper Limb Assessment（RULA）工具来确定人体工程学风险水平。评估了椅背高度与坐姿肩高、座位高度和腘高之间的不匹配情况。使用 Pearson Chi-Square 和 Spearman 相关检验进行统计分析。
参与者的年龄、身高、体重和 BMI 的中位数分别为 22 岁、1.70m、68kg 和 23.18kg/m2。大多数学生在大学使用固定家具写字时，姿势不符合人体工程学要求（RULA 总分中位数：4）。在高人体工程学风险水平下，座位高度的不匹配情况更为严重（54.4%），但椅背高度的不匹配情况并未呈现出类似的结果。
应开展更多包括可调式家具干预措施在内的前瞻性研究。
