OBJECTIVE
Affected by internet applications, mental health among older adults has become an important public health issue in China. This study aimed to use cross-sectional data to explore how internet use affects mental health among older adults in China, along with the moderating role of physical exercise in the above relationship.
METHODS
This study employed data from the Chinese General Social Survey (CGSS) conducted in 2017. In addition, OLS regression was adopted to explore the impacts of internet use on the mental health of older adults in China.
RESULTS
Results from the cross-sectional data model showed that internet use had a statistically significant and positive correlation with the mental health of older adults. The regression result of the full sample showed that the regression coefficient of the influence of internet use on the mental health of the elderly was 0.114, which was significant at the 1% level. Furthermore, this study used mediating analysis to explore the possible underlying mechanism by which internet use influenced mental health status through physical exercise. Physical exercise played a mediating role in the relationship between internet use and mental health; the ratio of the indirect effect to total effect mediated was 0.272. It is important to note that the effect size of the indirect effect through physical exercise was quite large.
CONCLUSION
Our findings suggested that internet use was significantly associated with better mental health status for older Chinese residents, mediated by higher physical exercise frequency, which was consistent with China's recent efforts to promote health governance with the "Internet Plus Exercise" campaign. Consequently, the government must encourage the development of more internet applications suitable for the elderly to increase their exercise frequency and ultimately improve their mental health. These results also provided insights for clinical solutions.
目的
受互联网应用影响，老年人心理健康已成为中国一个重要的公共卫生问题。本研究旨在利用横断面数据探讨互联网使用如何影响中国老年人的心理健康，以及体育锻炼在上述关系中的调节作用。
方法
本研究采用2017年中国综合社会调查（CGSS）的数据。此外，采用普通最小二乘法回归来探讨互联网使用对中国老年人心理健康的影响。
结果
横断面数据模型的结果表明，互联网使用与老年人心理健康存在统计学上显著的正相关。全样本回归结果显示，互联网使用对老年人心理健康影响的回归系数为0.114，在1%水平上显著。此外，本研究采用中介分析来探讨互联网使用通过体育锻炼影响心理健康状况的可能潜在机制。体育锻炼在互联网使用与心理健康的关系中起中介作用；中介的间接效应与总效应之比为0.272。需要注意的是，通过体育锻炼的间接效应的效应量相当大。
结论
我们的研究结果表明，互联网使用与中国老年居民更好的心理健康状况显著相关，通过更高的体育锻炼频率起中介作用，这与中国最近通过“互联网 + 运动”活动促进健康治理的努力一致。因此，政府必须鼓励开发更多适合老年人的互联网应用，以增加他们的锻炼频率并最终改善他们的心理健康。这些结果也为临床解决方案提供了见解。
