It is unclear if different types of sedentary behaviour during the adolescence are differentially associated with psychological distress during adolescence and adulthood. It is also unknown what may mediate this potential proposed association. The current study aimed to analyse the association of mentally-active and mentally-passive sedentary behaviours during adolescence (16y) with subsequent psychological distress during adulthood (42y), and to examine the role of potential mediators (42y). Data from the 1970 British Cohort Study was used (N = 1787). At age 16y participants reported time and frequency in mentally-passive (TV-viewing and watching movies) and mentally-active (reading books, doing homework and playing computer games) sedentary behaviours, psychological distress and organized sports participation. At 42y, participants reported cognition (vocabulary test), TV-viewing, psychological distress, self-rated health, body mass index and employment status. Education was collected throughout the follow-up years. Logistic regression and mediation models assessed associations. Multiple imputation using chained equations was used to assess the impact of missing data. Mentally-passive sedentary behaviour in adolescence was a risk factor for psychological distress during adulthood in complete-cases analysis [OR:1.44(95%CI:1.09-1.90)], which was confirmed by the model with multiple imputation. Mentally-active sedentary behaviour at 16y was not associated with psychological distress at 42y. Adult TV-viewing during weekends (24.7%), and self-rated health (19.0%) mediated the association between mentally-passive sedentary behaviour during adolescence and psychological distress during adulthood. However, the mediation was not clear in the models with multiple imputation. Mentally-passive sedentary behaviour during adolescence was associated with elevated psychological distress during adulthood and this association was mediated TV-viewing and self-rated health in adulthood.
目前尚不清楚青少年时期不同类型的久坐行为是否与青少年和成年期的心理困扰有差异相关。也不知道是什么可能介导了这种潜在的关联。本研究旨在分析青少年时期（16 岁）的精神活跃和精神被动久坐行为与成年期（42 岁）随后出现的心理困扰之间的关联，并探讨潜在中介因素的作用（42 岁）。本研究使用了 1970 年英国队列研究的数据（N=1787）。在 16 岁时，参与者报告了精神被动（看电视和看电影）和精神活跃（阅读书籍、做作业和玩电脑游戏）久坐行为、心理困扰和有组织的体育活动参与情况。在 42 岁时，参与者报告了认知（词汇测试）、看电视、心理困扰、自我评估的健康状况、体重指数和就业状况。教育情况在整个随访期间进行收集。逻辑回归和中介模型评估了关联。使用连锁方程的多重插补用于评估缺失数据的影响。在完全案例分析中，青少年时期的精神被动久坐行为是成年期心理困扰的一个风险因素[OR：1.44（95%CI：1.09-1.90）]，这一结果在多重插补模型中得到了证实。16 岁时的精神活跃久坐行为与 42 岁时的心理困扰无关。成年期周末的电视观看（24.7%）和自我评估的健康状况（19.0%）中介了青少年时期精神被动久坐行为与成年期心理困扰之间的关联。然而，在多重插补模型中，这种中介作用并不明显。青少年时期的精神被动久坐行为与成年期较高的心理困扰相关，这种关联在成年期通过电视观看和自我评估的健康状况来介导。
