Physical activity and self-compassion are closely related to individuals' mental health (eg, depression). However, most studies only examined their independent roles in mental health without considering the potential interaction between the two variables. The present study aimed to investigate the independent and joint associations between physical activity (PA) and self-compassion (SC) on depression symptoms and examine the additive interaction between PA and SC.
A cross-sectional design was utilized in the present descriptive study. By recruiting participants via social media platforms, 1846 Chinese college students completed International Physical Activity Questionnaire Short Form, the Self-Compassion Scale-Short Form, the 9-item Patient Health Questionnaire, and items regarding socio-demographic information. Independent and joint roles of low-level PA (LPA) and low-level SC (LSC) on depression symptoms were examined by logistic regression models. Additive interaction between LPA and LSC on depression symptoms was examined by the following indices: relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (S). Socio-demographic variables were included in the models as covariates.
Both LPA (OR = 1.47 [1.16, 1.86]) and LSC (OR = 5.74 [3.89, 8.45]) were independently associated with higher probability of depression symptoms. Combining LPA and LSC led to an additive interaction and greatly increased the odds of depression symptoms (OR = 9.62 [5.38, 17.22]; RERI = 2.47 [0.19, 4.75], AP = 0.25 [0.05, 0.44], S = 1.38 [1.02, 1.87]).
Both LPA and LSC were associated with an increased risk of depression symptoms. Moreover, combining LPA and LSC may develop an additive risk for depression symptoms. Future research and clinical intervention could integrate PA and SC to find a better way to resist depression symptoms.
身体活动和自我同情与个体的心理健康（如抑郁症）密切相关。然而，大多数研究仅考察了它们在心理健康中的独立作用，而未考虑这两个变量之间的潜在相互作用。本研究旨在探讨身体活动（PA）和自我同情（SC）对抑郁症状的独立和联合关联，并检验PA和SC之间的相加交互作用。
本描述性研究采用横断面设计。通过社交媒体平台招募参与者，1846名中国大学生完成了国际身体活动问卷简表、自我同情量表简表、9项患者健康问卷以及社会人口学信息相关项目。通过逻辑回归模型检验低水平PA（LPA）和低水平SC（LSC）对抑郁症状的独立和联合作用。通过以下指标检验LPA和LSC对抑郁症状的相加交互作用：交互作用所致相对超额危险度（RERI）、归因比例（AP）和协同指数（S）。社会人口学变量作为协变量纳入模型。
LPA（比值比[OR]=1.47[1.16，1.86]）和LSC（OR=5.74[3.89，8.45]）均与抑郁症状的较高发生概率独立相关。LPA和LSC联合导致相加交互作用，并大大增加了抑郁症状的发生几率（OR=9.62[5.38，17.22]；RERI=2.47[0.19，4.75]，AP=0.25[0.05，0.44]，S=1.38[1.02，1.87]）。
LPA和LSC均与抑郁症状风险增加相关。此外，LPA和LSC联合可能会增加抑郁症状的风险。未来的研究和临床干预可以整合PA和SC，以找到更好的方法来抵抗抑郁症状。
