BACKGROUND
The evidence on the association between sedentary behaviour and depression in adolescence is mixed. We aimed to investigate the association between mentally-active and mentally-passive sedentary behaviours at 11 years (11y) and depressive symptoms at 14y, and to examine potential mediators.
METHODS
UK Millennium Cohort Study data were used (n=7,124; 49% boys). At 11y, participants self-reported frequency of mentally-passive (listening to music, internet use) and mentally-active sedentary behaviours (reading, playing electronic games). Additional parental-reported behaviours (mentally-passive: TV viewing; mentally-active: homework) were summed with self-reported behaviours to represent continuous indicators of mentally-active and mentally-passive sedentary behaviour. Depressive symptoms were assessed (at 11y and 14y) using the short-version of Mood and Feelings Questionnaire. Body mass index (BMI), mentally-passive sedentary behaviour and cognition at 14y were examined as potential mediators. Linear regression models were adjusted for confounders and stratified by sex. Subsequent mediation analyses reporting e-values were used to assess unmeasured confounding.
RESULTS
Among girls, mentally-passive sedentary behaviour at 11y was associated with later depressive symptoms (14y) [β:0.089 (95%CI:0.055-0.122), e-value:1.32]. This association was mediated by BMI [5.6% (95%CI:4.1%-8.6%)] and mentally-passive sedentary behaviour [105.6% (95%CI:79.6%-156.7%)]. No associations were observed in boys or between mentally-active sedentary behaviour and later depressive symptoms.
LIMITATIONS
The parental report of behaviours and the assessment of mediators and outcome in the same wave are the main limitations.
CONCLUSION
Future interventions aiming to improve mental health among girls could aim to reduce mentally-passive sedentary behaviour in early teens and could target potential mediators including BMI.
背景
关于青少年久坐行为与抑郁之间的关联，现有证据尚不一致。本研究旨在探究 11 岁时的精神活跃型和精神被动型久坐行为与 14 岁时的抑郁症状之间的关联，并探讨潜在的中介因素。
方法
本研究使用英国千禧年队列研究的数据（n=7124；49%为男性）。11 岁时，参与者自我报告精神被动型（听音乐、上网）和精神活跃型久坐行为（阅读、玩电子游戏）的频率。父母报告的行为（精神被动型：看电视；精神活跃型：家庭作业）与自我报告的行为相加，代表精神活跃型和精神被动型久坐行为的连续指标。使用情绪和感觉问卷的简短版本评估抑郁症状（在 11 岁和 14 岁时评估）。14 岁时的体质指数（BMI）、精神被动型久坐行为和认知被视为潜在的中介因素。线性回归模型在调整混杂因素后按性别分层。随后使用报告有效范围值的中介分析来评估未测量的混杂因素。
结果
在女孩中，11 岁时的精神被动型久坐行为与以后的抑郁症状（14 岁时）相关（β：0.089（95%CI：0.055-0.122），有效范围值：1.32）。这种关联由 BMI [5.6%（95%CI：4.1%-8.6%）]和精神被动型久坐行为[105.6%（95%CI：79.6%-156.7%）]介导。在男孩或精神活跃型久坐行为与以后的抑郁症状之间未观察到相关性。
局限性
行为的父母报告以及在同一波次中评估中介因素和结局是主要的局限性。
结论
未来旨在改善女孩心理健康的干预措施可能旨在减少青少年早期的精神被动型久坐行为，并可能针对潜在的中介因素，包括 BMI。
