Abstract

BACKGROUND

Regular physical activity treatment has been advocated for the prevention and rehabilitation of patients at risk of cardiovascular diseases and depressive symptoms. How physical activity is related to depressive symptoms is widely discussed.

OBJECTIVE

The aim of this internet-based study was to investigate the role of perceived social support in the relationship between physical activity habit strength and depressive symptoms.

METHODS

In total, 790 participants (mean 50.9 years, SD 12.2, range 20-84 years) who were interested in reducing their cardiovascular risk were recruited in Germany and the Netherlands. Data collection was conducted via an internet-based questionnaire addressing physical activity habit strength, depressive symptoms, and perceived social support. Cross-sectional data analysis was done with SPSS version 24 using the Macro PROCESS version 2 16.3 by Hayes with bootstrapping (10,000 samples), providing 95% CIs.

RESULTS

Physical activity habit strength was negatively related to depressive symptoms (r=-.13, P=.006), but this interrelation disappeared when controlling for perceived social support (beta=-.14, SE 0.09, P=.11). However, there was an indirect relationship between physical activity habit strength and depressive symptoms, which was mediated via perceived social support (beta=-.13; SE 0.04, 95% CI -0.21 to 0.06). The negative relationship between physical activity habit strength and depressive symptoms was fully mediated by perceived social support.

CONCLUSIONS

We suggest that physical activity treatment in people interested in reducing their cardiovascular risk should also embed social support to target depressive symptoms. Internet-based interventions and electronic health may provide a good option for doing so.

摘要

背景

规律的体育活动治疗已被提倡用于心血管疾病和抑郁症状风险患者的预防与康复。体育活动与抑郁症状之间的关系备受广泛讨论。

目的

这项基于互联网的研究旨在探讨感知社会支持在体育活动习惯强度与抑郁症状关系中的作用。

方法

在德国和荷兰共招募了790名有兴趣降低心血管风险的参与者（平均年龄50.9岁，标准差12.2，年龄范围20 - 84岁）。通过基于互联网的问卷收集有关体育活动习惯强度、抑郁症状和感知社会支持的数据。使用SPSS 24版本和Hayes的Macro PROCESS版本2 16.3进行横断面数据分析，并采用自抽样法（10,000个样本），提供95%的置信区间。

结果

体育活动习惯强度与抑郁症状呈负相关（r = -0.13，P = 0.006），但在控制感知社会支持后，这种相互关系消失（β = -0.14，标准误0.09，P = 0.11）。然而，体育活动习惯强度与抑郁症状之间存在间接关系，通过感知社会支持介导（β = -0.13；标准误0.04，95%置信区间 -0.21至0.06）。体育活动习惯强度与抑郁症状之间的负相关完全由感知社会支持介导。
