Depression, a prevalent mental illness among older people, is associated with some adverse health problems and lower quality of life. Against the backdrop of a growing aging population, coping with late-life depression has become an important public health priority. Emerging evidence suggests that short video addiction tendency may be a new risk factor for depression. However, there has been limited discussion on the potential association between short video addiction tendency and depression among older adults.
We aimed to investigate the relationship between short video addiction tendency and depression in a sample of rural older adults. In addition, we aimed to examine the mediating roles of asthenopia and sleep efficiency in the relationship between short video addiction tendency and depression.
A face-to-face interview design was used to collect valid data from 872 rural older adults aged ≥60 years from October 2024 to January 2025 in 2 provinces of China. Participants were requested to complete self-report measures on short video addiction tendency (Short Video Addiction Scale), asthenopia (11-item Asthenopia Survey Questionnaire), sleep efficiency (actual sleep time and time in bed at night), and depression (Center for Epidemiologic Studies Depression Scale). Linear regression analyses were performed using model 6 of the PROCESS 4.1 macro in SPSS 26.0 to assess the relationship between short video addiction tendency and depression and to examine the mediating roles of asthenopia and sleep efficiency in this relationship, adjusting for sex, age, education, and marital status.
We observed that the prevalence of depression was 27.8% (242/872) in this study. There was a significant positive relationship between short video addiction tendency and depression (β=.263; P<.001). Short video addiction tendency affected depression through 3 different pathways: the mediating role of asthenopia (β=.084, 95% CI .059-.114); the mediating role of sleep efficiency (β=.021, 95% CI .001-.043); and the chain mediating role of asthenopia and sleep efficiency (β=.017, 95% CI .010-.026). The effect values of the 3 pathways accounted for 31.94%, 7.99%, and 6.46% of the total effect, respectively.
We highlighted a direct and statistically substantial relationship between short video addiction tendency and depression, with asthenopia and sleep efficiency serving as potential mediating factors. Our findings predicted that guiding and assisting rural older adults to use short video apps appropriately, addressing asthenopia, and enhancing sleep efficiency may be a valuable approach to improve their mental health, preventing and delaying the occurrence and development of depression.
抑郁症是老年人中一种普遍存在的精神疾病，与一些不良健康问题及较低的生活质量相关。在人口老龄化不断加剧的背景下，应对老年期抑郁症已成为重要的公共卫生优先事项。新出现的证据表明，短视频成瘾倾向可能是抑郁症的一个新的风险因素。然而，关于老年人短视频成瘾倾向与抑郁症之间的潜在关联的讨论有限。
我们旨在调查农村老年人群样本中短视频成瘾倾向与抑郁症之间的关系。此外，我们旨在检验视疲劳和睡眠效率在短视频成瘾倾向与抑郁症关系中的中介作用。
采用面对面访谈设计，于2024年10月至2025年1月在中国2个省份收集了872名年龄≥60岁的农村老年人的有效数据。要求参与者完成关于短视频成瘾倾向（短视频成瘾量表）、视疲劳（11项视疲劳调查问卷）、睡眠效率（实际睡眠时间和夜间卧床时间）和抑郁症（流行病学研究中心抑郁量表）的自我报告测量。使用SPSS 26.0中PROCESS 4.1宏的模型6进行线性回归分析，以评估短视频成瘾倾向与抑郁症之间
