Abstract

BACKGROUND

This study addresses the nexus of stress, physical exercise, and internet addiction in college students, aiming to unravel their complex interactions. With prior research hinting at correlations, this study seeks deeper insights into the optimal exercise duration and the mediating role of physical activity in the stress-internet addiction relationship.

METHODS

We examined 2892 Chinese college students, assessing psychosocial traits via established scales: the Chinese Internet Addiction Scale (CIAS-R), International Physical Activity Questionnaire (IPAQ), and DASS-21 for stress. We adopted a questionnaire survey method to collect data, and through convenience sampling, participants were selected. Analysis involved Structural Equation Model (SEM) and restricted cubic splines (RCS).

RESULTS

Among participants, 22.0 % self-reported internet addiction symptoms. Notably, a non-linear correlation between moderate (MPA) and vigorous physical activity (VPA) and internet addiction was evident (P < 0.001), while light physical activity (LPA) showed no significant association (P = 0.182). MPA initially reduced internet addiction as activity hours increased, but its efficacy lessened after 0.8 h/day. Conversely, VPA's impact fluctuated, declining from 0 to 0.18 h/day, then stabilizing. SEM analysis highlighted VPA and MPA's partial mediation in the stress-internet addiction relationship. Specifically, the path coefficient from stress to MPA was -0.037 (P < 0.05), and the path coefficient from MPA to internet addiction was -0.056 (P < 0.01). Additionally, the path coefficient from stress to VPA was -0.067 (P < 0.001), and the path coefficient from VPA to internet addiction was -0.102 (P < 0.001).

CONCLUSION

This study unveils the intricate interplay between physical activity, stress, and internet addiction among college students. With 22.0 % reporting addiction symptoms, urgent interventions tailored to promoting healthy physical activity levels are imperative to mitigate internet addiction risks.

LIMITATIONS

The cross-sectional nature of our design precludes the establishment of causal relationships between psychological stress and internet addiction.

摘要

背景

本研究旨在探讨大学生压力、体育锻炼和网络成瘾之间的关系，深入了解两者之间的复杂相互作用。先前的研究表明这些因素之间存在相关性，因此本研究旨在进一步探讨最佳运动时间以及身体活动在压力与网络成瘾关系中的中介作用。

方法

我们对 2892 名中国大学生进行了评估，采用了已有的量表来评估心理社会特征：中文网络成瘾量表（CIAS-R）、国际体力活动问卷（IPAQ）和用于评估压力的 DASS-21。我们采用问卷调查法收集数据，通过便利抽样选择参与者。分析采用结构方程模型（SEM）和限制立方样条（RCS）。

结果

在参与者中，有 22.0%的人报告有网络成瘾症状。值得注意的是，中等到剧烈的体育活动（MPA 和 VPA）与网络成瘾之间存在非线性关系（P<0.001），而轻度体育活动（LPA）则没有显著关联（P=0.182）。MPA 随着活动时间的增加，最初会降低网络成瘾，但在每天 0.8 小时后效果减弱。相反，VPA 的影响呈波动状，从 0 到 0.18 小时/天下降，然后稳定。SEM 分析突出了 VPA 和 MPA 在压力与网络成瘾关系中的部分中介作用。具体来说，压力到 MPA 的路径系数为-0.037（P<0.05），而 MPA 到网络成瘾的路径系数为-0.056（P<0.01）。此外，压力到 VPA 的路径系数为-0.067（P<0.001），而 VPA 到网络成瘾的路径系数为-0.102（P<0.001）。
