摘　　要：目的探讨大学生大五人格、体力活动和骨密度的关联。方法招募某体育高校本科生705名(男329名,女376名)。将其按照运动训练经历分为六大组运动项目,分别为:球类、技巧、重竞技、田径、休闲和无运动项目。接受专业的体育训练的学生(体育生)分入球类组、技巧组、重竞技组、田径项目组,其余(非体育生)则分入休闲组和无运动项目组。采用中国版10项目大五人格量表(TIPI-C)测得受试者开放性、尽责性、外向性、宜人性和神经质这五种人格特质;采用GT3X+三轴加速传感器测量其日常连续7 d体力活动水平,设置界值参数,将体力活动分为轻强度(LPA)、中等强度(MPA)和大强度(VPA);采用双能X线检测上肢、下肢及全身骨密度值。采用PROCESS检验和Sobel检验探讨体育活动或大五人格模型的中介作用。以体力活动和大五人格作为中介变量,探讨大五人格、体力活动和骨密度之间的关联性。对六大组运动项目进行体力活动和骨密度比较。利用相关性分析探讨不同强度体力活动和骨密度之间的关联性。结果虽然体力活动、大五人格与骨密度之间存在90种潜在的关系,但只有3种关系显著。当尽责性是自变量,MPA是中介变量,PROCESS的结果差异有统计学意义(P<0.01),MPA对上肢骨密度的中介效应为17.3%,对下肢骨密度的中介效应为19.4%,对全身骨密度的中介效应为19.1%。男生中,六大项目的LPA差异无统计学意义,MPA和VPA差异有统计学意义(P<0.05);女生中,LPA、MPA和VPA在六大项目中的差异均有统计学意义。且MPA和VPA的差异更为明显(P<0.05)。无论男生还是女生,上肢、下肢和整体骨密度在六大项目的整体比较中,差异皆有统计学意义(P<0.05),这种差异在女生中更加明显。在男生和女生中,LPA和骨密度之间没有相关性。MPA、VPA均与骨密度呈正相关,其中MPA与上肢骨密度、下肢骨密度、全身骨密度的�Objective To explore the correlation between 5 dimensions of personality,physical activity(PA),and bone mineral density(BMD)among college students.Methods A total of 705 undergraduates(329 males and 376 females)from a sports university were recruited.Based on their sports training experience,the participants were divided into 6 major sports groups,including ball sports,skilled sports,competitive sports,track and field,leisure sports,and no sports.Students with professional sports training(ie,athletes)were categorized into ballgame,skilled,competitive,and track and field groups,while the rest(non-athletes)were placed in leisure and no sports groups.Ten-Item Personality Inventory in China(TIPI-C),or the 5-factor model of personality,was used to measure the 5 personality dimensions of openness,conscientiousness,extraversion,agreeableness,and neuroticism of the participants.Their daily level was measured with GT3X+triaxial accelerometers over 7 continuous days.Then,parameter thresholds were established and the participants'PA was categorized as light(LPA),moderate(MPA),and vigorous(VPA).The bone mineral density(BMD)of arms,legs,and the total body was measured using dual-energy X-ray absorptiometry.The mediation effect of PA and that of the 5-factor model of personality were tested using PROCESS and Sobel tests.The correlation between the 5 personality dimensions,PA,and BMD was explored,with PA and the 5 personality dimensions as mediator variables.A comparison of PA and BMD was conducted across the 6 major sports groups.The correlation between PA of different intensities and BMD was also analyzed using Spearman's correlation.Results Although there were 90 potential relationships between PA,the 5 personality dimensions,and BMD,only 3 were significant.When conscientiousness was used as an independent variable and MPA,as a mediating variable,statistically significant differences in PROCESS results were reported(P<0.01),with MPA mediating 17.3%of arm BMD,19.4%of leg BMD,and 19.1%of total body BMD.Among male students,ther
