title: Bidirectional association between sedentary behaviour and depressive symptoms in adolescent girls.
abstract: 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.
