摘要:

[目的]探讨运动在气郁质得分与健康相关生命质量（HRQOL）间的中介效应。[方法]采用横断面现场调查法，于2015年3月-2016年12月在北京、河北获得2 113例有效样本数据。运动水平由自我报告获得；气郁质得分采用中医体质量表气郁质亚量表计算；HRQOL评价采用简明健康状况调查问卷SF-36，获得生理领域（PCS）、心理领域（MCS）及其总体HRQOL得分。在相关分析的基础上，进一步应用分层多元线性回归模型探讨运动的中介效应。[结果]1）气郁质得分与PCS（r=-0.461，P<0.01）、MCS（r=-0.564，P<0.01）以及总体HRQOL（r=-0.573，P<0.01）呈负相关；运动水平与气郁质得分（r=-0.108，P<0.01）呈负相关，与PCS（r=0.115，P<0.01）、MCS（r=0.100，P<0.01）以及总体HRQOL（r=0.111，P<0.01）呈正相关。2）运动在气郁质得分与PCS、MCS和总体HRQOL间的中介效应分析具有统计学意义，中介效应量分别为0.93%、0.53%和0.69%。[结论]运动在气郁质对健康相关生命质量的负向影响中具有中介效应，但中介效应量较小，仅占不到1%。

Abstract:

[Objective] To evaluate the effect of exercise on the relationship between qi depression constitution and health-related quality of life (HRQOL).[Methods] From March 2015 to December 2016,2113 valid sample data were obtained in Beijing and Hebei. The classification of exercise level is obtained from self-report;the score of qi depression constitution is calculated by the traditional Chinese medicine (TCM) qi depression subscale;using SF-36 evaluates health-related quality of life (HRQOL) that acquires scores of Physical Component Summary (PCS),Mental Component Summary (MCS) and overall HRQOL. On the basis of correlation analysis,applying the Hierarchical Multiple Linear Regression Model to explore the mediating effect of exercise.[Results] 1) The negative correlation between qi depression constitution and Physical Component Summary (PCS,r=-0.461,P<0.01) and Mental Component Summary (MCS,r=-0.564,P<0.01) and overall HRQOL (r=-0.573,P<0.01) were significant.The negative correlation between exercise and qi depression constitution (r=-0.108,P<0.01) was significant. The positive correlation between exercise and PCS (r=0.115,P<0.01),MCS (r=0.100,P<0.01),and overall HRQOL (r=0.111,P<0.01) were significant. 2)The mediation effects of exercise on the relationship between qi depression constitution and PCS,MCS and overall HRQOL were significant,and the mediating effect were 0.93%,0.53% and 0.69%.[Conclusion] Exercise has a mediating effect on the negative influence of qi depression constitution on health-related quality of life. However,the mediating effect is small,accounting for less than 1%.
