摘　　要：目的分析哈尔滨市2010—2024年学生身体形态指标与比例的变化趋势,探讨学校课桌椅功能尺寸与当前学生形态指标的适配性,为课桌椅标准修订提供参考依据。方法分别于2010及2024年的9—11月,采用方便抽样与分层整群抽样相结合的方法,在哈尔滨市抽取3个区的学生共6590和6252名,测量并比较15年间学生的身高、坐高、小腿长、大腿长等形态指标与比例变化,并将2024年数据与现行学校课桌椅标准功能尺寸进行比较。采用t检验、Mann-Whitney U检验进行统计分析。结果2010—2024年,男、女生身高平均增量分别为1.8和1.5 cm,坐高增量均为1.5 cm,小腿长增量为0.3和0.4 cm,大腿长增量均为0.5 cm;坐高/身高、坐高/腿长的平均增量均小于0.1。桌椅高差与1/3坐高的差值在0.4~0.8 cm,适配0号课桌椅的学生中有22.0%桌椅高差与1/3坐高差值小于0,身高较高学生使用课桌椅时,桌椅高差可能存在不足;座面高与腓骨点高的差值在-1.4~1.1 cm,座面深与腘臀长的差值在-9.8~-3.4 cm;肥胖学生中,座面宽与1/2臀围的差值在-20.5~-8.7 cm,非肥胖学生的差值在-12.2~-3.8 cm。结论现行课桌椅标准基本满足卫生学要求,但对超高及肥胖学生需要通过调整课桌椅分配或进行个性化调整以满足卫生学要求。Objective To analyze the change trends in the body shape indicators and proportions of students in Harbin from 2010 to 2024,and to investigate ergonomic compatibility of functional dimensions of school desks and chairs with current student shape indicators,so as to provide a reference for revising furniture standards of desks and chairs.Methods Between September and November of both 2010 and 2024,a combination of convenience sampling and stratified cluster random sampling was conducted across three districts in Harbin,yielding samples of 6590 and 6252 students,respectively.Anthropometric shape indicators cluding height,sitting height,crus length,and thigh length-and their proportional changes were compared over the 15-year period.The 2024 data were compared with current standard functional dimensions of school furniture.The statistical analysis incorporated t-test and Mann-Whitney U test.Results From 2010 to 2024,average height increased by 1.8 cm for boys and 1.5 cm for girls;sitting height increased by 1.5 cm for both genders;crus length increased by 0.3 cm for boys and 0.4 cm for girls;and thigh length increased by 0.5 cm for both genders.The ratios of sitting height to height,and sitting height to leg length increased by less than 0.1.The difference between desk-chair height and 1/3 sitting height ranged from 0.4-0.8 cm.Among students matched with size 0 desks and chairs,22.0%had a desk-to-chair height difference less than 0,indicating that the desk-to-chair height difference might be insufficient for taller students.The differences between seat height and fibular height ranged from-1.4 to 1.1 cm;and the differences between seat depth and buttock-popliteal length ranged from-9.8 to 3.4 cm.Among obese students,the differences between seat width and 1/2 hip circumference ranged from-20.5 to-8.7 cm,while it ranged from-12.2 to-3.8 cm among non-obese students.Conclusion Current furniture standards basically satisfy hygienic requirements;however,in the case of exceptionally tall and obese students,ergonomic accomm
