现代生活方式的特点是大量长时间久坐不动的活动，这可能会对健康构成风险，尽管对心理健康的影响知之甚少。我们研究了几种常见的久坐行为（看电视、上网、阅读）与心理健康不同方面之间的关系。我们对来自英国老龄化纵向研究的6359名（年龄64.9 ± 9.1岁）男性和女性进行了为期两年的随访，这是一个社区居住老年人队列。自我报告的电视观看时间，阅读，和使用互联网进行了评估的基线。使用流行病学研究中心抑郁症（CES-D）量表的8项来评估心理健康，以测量抑郁症状，并使用记忆和语言流畅性的神经心理学测试来评估认知功能。在基线时，看电视时间（≥ 6小时/天vs <2小时/天）与抑郁症状（系数= 0.49，95% CI，0.63 - 0.35）和整体认知功能（−1.16，−1.00 - −1.31）较差相关。相反，使用互联网的参与者报告了较低的抑郁症状（-0.58，-0.50--0.66）和较高的整体认知功能（1.27，1.37 - 1.18）。基线时的任何久坐行为与随访期间心理健康指标的变化之间没有关联，这表明分数的差异持续存在，但不会随着时间的推移而增加。一些但不是所有的久坐行为都与不良的心理健康有关。这些关联很可能是由它们发生的对比鲜明的环境和社会背景驱动的。
Modern day lifestyles are characterized by large amounts of prolonged sedentary activities, which may pose a risk to health in its own right although little is known about the effects on mental health. We examined the association between several types of common sedentary behaviors (TV viewing, internet use, reading), and different aspects of mental health. We conducted a two year follow-up of 6359 (aged 64.9 ± 9.1 yrs) men and women from the English Longitudinal Study of Ageing, a cohort of community dwelling older adults. Self-reported TV viewing time, reading, and use of the internet was assessed at baseline. Mental health was assessed using the 8-item Centre of Epidemiological Studies Depression (CES-D) scale to measure depressive symptoms, and neuropsychological tests of memory and verbal fluency to assess cognitive function. At baseline TV viewing time (≥6hrs/d versus <2 hrs/d) was associated with higher depressive symptoms (coefficient = 0.49, 95% CI, 0.63 – 0.35) and poorer global cognitive function (−1.16, −1.00 – −1.31). Conversely, participants using the internet reported lower depressive symptoms (−0.58, −0.50 – −0.66) and higher global cognitive function (1.27, 1.37 – 1.18). There was no association between any sedentary behaviors at baseline and change in mental health measures over follow-up, suggesting that the difference in scores persisted but did not increase over time. Some, but not all sedentary behaviors are linked to adverse mental health. It is likely that these associations are being driven by the contrasting environmental and social contexts in which they occur.
