摘要:
探讨女大学生完美主义和进食障碍的关系以及体育锻炼在其中的调节作用,为预防女大学生进食障碍的发生提供理论依据.方法 采用中文Frost多维度完美主义问卷、进食障碍问卷以及体育活动等级量表,对方便抽取的山东省3所高校的1 938名女大学生进行调查.结果 132名女生达到进食障碍倾向标准,患病率为5.11%.四年级女生的患病率高于其他3个年级.不同生源地、不同专业的女大学生患病率差异无统计学意义(x2值分别为1.43,1.58,P值均>0.05).超重组女大学生患病率高于正常组和偏瘦组(x2=7.15,P<0.01).完美主义能正向预测进食障碍(β=0.431,P<0.01),完美主义和体育锻炼交互项的回归系数有统计学意义(B=-0.106,P<0.01).当锻炼量较低时,完美主义对进食障碍的预测作用较大(B=0.53,t=5.93,P<0.01);锻炼量较高时,完美主义对进食障碍的影响减弱(B=0.32,t=2.37,P<0.05).结论 体育锻炼在完美主义影响进食障碍的过程中具有调节作用.
Abstract:
Objective To explore the moderating effect of physical exercise in relationship between perfectionism and eating disorder among female college students.Methods A total of 1 938 female college students from three universities in Shandong province participated in this study and completed Chinese Frost Multidimensional Perfectionism Scale,Eating Disorders Inventory and Physical Activity Rating Scale.Results All the 132 female students met the criteria of eating disorders,the estimated prevalence rate was 5.11%.The prevalence was highest among senior students.No significant differences were found in eating disorder prevalence regarding to living residence and college major.Overweight students were more likely to have eating disorders than normal and lean group.Perfectionism positively associated with eating disorders (β=0.431,P<0.01);Significant interaction between perfectionism and physical exercise was found in the prediction of eating disorder (B=-0.106,P<0.01);perfectionism had a significant predictive effect on eating disorders when exercise was insufficient (B=0.53,t =5.93,P<0.01);the effect of perfectionism on eating disorders decreased when exercise was sufficient (B=032,t=2.37,P<0.05).Conclusion Physical exercise mediates the effects of perfectionism on eating disorders.
