To examine longitudinal associations between sedentary behavior and depressive symptoms among adolescent girls.
A 6-year longitudinal study was conducted consisting of 3 waves, each separated by 3 years. Participants' (n = 249, mean age 12.1 y at baseline) sedentary behaviors were registered using ecological momentary assessment and girls completed the Center for Epidemiological Studies Depression scale. Structural equation modeling of cross-lagged panel models was used to test longitudinal and bidirectional associations.
The findings showed that the autoregressive effects were stable for sedentary behavior and depressive symptoms. The cross-lagged effects indicated that the depressive symptoms positively predicted sedentary behavior from early to late adolescence. However, sedentary behavior did not predict depressive symptoms across adolescence.
This study shows 1-directional long-term effect of depressive symptoms on sedentary behavior in adolescent girls. Future research on longitudinal relationships between sedentary behavior and depressive symptoms among children and adolescents are needed.
研究青少年女性久坐行为与抑郁症状之间的纵向关联。
进行了一项为期 6 年的纵向研究，包括 3 个时间点，每个时间点相隔 3 年。参与者（n=249，基线时平均年龄为 12.1 岁）的久坐行为使用生态瞬时评估进行记录，女孩们完成了流行病学研究抑郁量表。使用交叉滞后面板模型的结构方程建模来测试纵向和双向关联。
研究结果表明，久坐行为和抑郁症状的自回归效应是稳定的。交叉滞后效应表明，抑郁症状从青春期早期到晚期正向预测久坐行为。然而，久坐行为在整个青春期并没有预测抑郁症状。
这项研究表明，青少年女性抑郁症状对久坐行为有单向长期影响。需要对儿童和青少年久坐行为与抑郁症状之间的纵向关系进行进一步研究。
