: To explore the potential classroom furniture mismatch with students' anthropometric measurements and back pain related to sitting for extended periods. This cross-sectional study was carried out on all twelve male and female intermediate and secondary schools located in Abha city. Anthropometric and classroom furniture measurements were assessed, and the mismatch was determined using standardized methods. Students were also screened for back pain related to long sitting at school. A total number of 879 students was selected. The study revealed seat height mismatch in both intermediate, and secondary school of 84.3%, and 75.6%, respectively. Seat depth mismatch was 74.0% in intermediate schools and reached 84.5% in secondary schools. The desk height was improper for 94.1%, and 82.3% of students in intermediate, and secondary schools, respectively. The levels of mismatch differ significantly by grade level and gender. A prevalence of 10.8% of back pain related to long sitting at school was found. In multivariable logistic regression, males, intermediate school children, and the presence of buttock-popliteal length/seat depth mismatch were significantly associated with pain. On the other hand, practicing exercise was a significant protective factor. There is a prevalent mismatch between students' dimensions and existing schools' furniture. School furniture providers should take in consideration the average Saudi students' dimensions, while designing school furniture especially for males, and at intermediate schools, or provide schools with adjustable seats and desks.
: 探讨学生人体测量尺寸与长时间坐姿相关背痛之间潜在的课桌椅不匹配问题。本横断面研究在阿巴哈市的所有 12 所男女中学进行。评估了人体测量和课桌椅尺寸，并使用标准化方法确定了不匹配情况。还对学生在学校长时间坐着时的背痛进行了筛查。共选择了 879 名学生。研究显示，中学和高中的座椅高度不匹配率分别为 84.3%和 75.6%。中学的座椅深度不匹配率为 74.0%，而高中的座椅深度不匹配率达到 84.5%。中学和高中的课桌高度分别有 94.1%和 82.3%的学生不合适。不匹配程度在年级和性别上有显著差异。发现与在学校长时间坐着相关的背痛患病率为 10.8%。在多变量逻辑回归中，男性、中学生以及臀-小腿长度/座椅深度不匹配与疼痛显著相关。另一方面，进行锻炼是一个显著的保护因素。学生尺寸与现有学校家具之间存在普遍不匹配。学校家具供应商在设计学校家具时，特别是对于男性和中学生，应考虑沙特学生的平均尺寸，或者为学校提供可调节的座椅和桌子。
