This study examined longitudinal and bidirectional association between sedentary behaviour (SB) and depressive symptoms (DS) in adolescent girls. Participants (n = 253) completed measures of SB and DS at three time points spanning a four-year interval. DS were obtained using the modified Centre for Epidemiological Depression Scale (CES-D). Weekday and weekend SB was assessed using a questionnaire. In the latent growth model, both SB and DS increased and the change in SB was positively associated with change in DS (β = 0.24). Higher levels of SB at baseline were associated with larger increases in DS over time (β = 0.23), and higher baseline levels of DS were associated with smaller increases in SB over time (β = -0.17). These findings suggest persistent longitudinal and bidirectional associations between SB and DS and encourage the design of interventions that limit sedentary time as a possible means of reducing adolescent depression.
本研究调查了青春期女孩久坐行为（SB）与抑郁症状（DS）之间的纵向和双向关联。参与者（n = 253）在跨越四年间隔的三个时间点完成了SB和DS的测量。DS通过改良的流行病学抑郁量表（CES-D）获得。工作日和周末的SB通过问卷调查进行评估。在潜在增长模型中，SB和DS均增加，且SB的变化与DS的变化呈正相关（β = 0.24）。基线时较高的SB水平与随时间DS的更大增加相关（β = 0.23），而基线时较高的DS水平与随时间SB的较小增加相关（β = -0.17）。这些发现表明SB和DS之间存在持续的纵向和双向关联，并鼓励设计限制久坐时间的干预措施，作为减少青少年抑郁的一种可能手段。
