更多的体力活动（PA）和更少的屏幕时间（ST）与青少年的心理健康呈正相关;然而，研究受到短期设计和检查PA时排除ST的限制。我们检查了：（a）在11年的4次评估中PA、ST、抑郁症状和焦虑症状的变化，以及（B）初始PA、ST与抑郁和焦虑症状之间的双向关系，作为青春期彼此变化的预测因子。在2006年至2010年期间，来自加拿大渥太华的参与者（时间1; N = 1160，平均年龄= 13.54岁）在四个时间点完成了涵盖10至21岁的问卷调查。使用潜在增长模型。PA随着时间的推移而下降，而ST和抑郁和焦虑症状随着时间的推移而增加。控制性别，种族，学校位置，zBMI，出生年份和父母的教育程度，最初较高的焦虑与最初较高的ST相关（协方差= 0.001）。88，p <0.05）和最初较低的PA（协方差=-6.84，p = 0.07）独立于抑郁症的初始症状。较高的初始抑郁与较高的初始ST相关（协方差= 2.55，p <0.05）。焦虑的增加与ST的增加相关（协方差= 0.001）。07，p =. 06)以及抑郁症的增加（协方差=。41，p < .05）。检查双向关系，较高的抑郁症初始症状预示着PA的较大下降（B = -.28，p < .05）。在初始PA、ST、焦虑或抑郁之间没有发现其他显著结果作为彼此变化的预测因素。针对13岁左右抑郁症的干预可能有助于防止PA进一步下降。同样，无论PA如何，减少ST的干预措施可能有利于同时减少抑郁和焦虑症状。(C)2016 Elsevier Inc.

More physical activity (PA) and less screen time (ST) are positively associated with mental health in adolescents; however, research is limited by short-term designs and the exclusion of ST when examining PA. We examined: (a) changes in PA, ST, symptoms of depression, and symptoms of anxiety over four assessments spanning 11 years, and (b) bidirectional relationships between initial PA, ST, and symptoms of depression and anxiety as predictors of change in each other during adolescence. Between 2006 and 2010, participants from Ottawa Canada (Time1; N = 1160, Mean age = 13.54 years) completed questionnaires at four points covering the ages from 10 to 21 years. Latent growth modeling was used. PA decreased over time whereas ST and symptoms of depression and anxiety increased over time. Controlling for sex, ethnicity, school location, zBMI, birth year, and parents' education, initially higher anxiety was associated with initially higher ST (covariance =. 88, p < .05) and initially lower PA (covariance = -6.84, p = .07) independent of initial symptoms of depression. Higher initial depression was associated with higher initial ST (covariance = 2.55, p < .05). Increases in anxiety were associated with increases in ST (covariance =. 07, p =. 06) and increases in depression (covariance =. 41, p < .05). Examining bidirectional relationships, higher initial symptoms of depression predicted greater decreases in PA (b = -.28, p < .05). No other significant findings between initial PA, ST, anxiety, or depression were found as predictors of change in each other. Interventions targeting depression around age 13 may be useful to prevent further declines in PA. Similarly, interventions to reduce ST may be beneficial for concurrent reductions in symptoms of depression and anxiety, irrespective of PA. (C) 2016 Elsevier Inc. All rights reserved.
