我们研究了屏幕时间（ST）和心理健康问题之间的关系，以及ST的增量和心理健康问题的进展，在大学为基础的样本，中国青年。我们从2013年10月至2014年12月对2521名中国大学新生进行了评估。基线时，参与者的平均年龄为18.43岁（SD 0.96岁），1215名（48.2%）参与者报告ST >2小时/天。 根据基线ST暴露和随访时暴露的变化，我们使用logistic回归模型估计了发生心理健康问题（焦虑、抑郁和精神病理学症状）和/或这些问题进展的风险的多变量调整OR。基线时，当ST >2 h/d与ST ≤2 h/d比较时，焦虑、抑郁和精神病理症状的OR分别为1.38（95%CI 1.15 - 1.65）、1.55（95%CI 1.25 - 1.93）和1.49（95%CI 1.22 - 1.83）。 在对性别、年龄、居住背景、身体质量指数、家庭经济状况、睡眠质量、吸烟、饮酒、放学后锻炼和体育活动进行额外调整后，抑郁和精神病理学症状的结果保持不变，但焦虑的结果没有变化。当将ST暴露增加至>2小时/天的参与者与ST无变化且≤2小时/天的参与者进行比较时，焦虑的OR为1.78（95%CI 1.12至2.83），抑郁的OR为1.92（95%CI 1.23至2.83），精神病理学症状的OR为1.93（95%CI 1.16至3.21）。 这些关联在进一步调整后仍然存在。ST/ST增量对心理健康问题及其进展的总体影响是一致的，但很小。鉴于目前结果的效应量较小，尚不清楚ST在多大程度上是心理健康结果的实际显著风险因素。未来高质量的研究是必要的，以进一步研究这种关联和因果关系的方向。
We examined the relationships between screen time (ST) and mental health problems and also increment of ST and progression of mental health problems in a college-based sample of Chinese youth. We assessed 2521 Chinese college freshmen from October 2013 to December 2014. At baseline, the mean age of participants was 18.43 years (SD 0.96 years), and 1215 (48.2%) participants reported ST >2 h/day. We estimated multivariable-adjusted ORs by using logistic regression models for the risk of developing mental health problems (anxiety, depression and psychopathological symptoms) and/or progression of these problems, according to baseline ST exposure and changes in exposure at follow-up. At baseline, when ST >2 h/day was compared with ST ≤2 h/day, the OR was 1.38 (95% CI 1.15 to 1.65) for anxiety, 1.55 (95% CI 1.25 to 1.93) for depression and 1.49 (95% CI 1.22 to 1.83) for psychopathological symptoms. The results remained unchanged for depressive and psychopathological symptoms but not for anxiety, after additional adjustment for sex, age, residential background, body mass index, perceived family economy, sleep quality, smoking, alcohol intake, exercise after school and physical activity. When participants who had increased their ST exposure to >2 h/day were compared with those with no change and ST ≤2 h/day, the OR was 1.78 (95% CI 1.12 to 2.83) for anxiety, 1.92 (95% CI 1.23 to 2.83) for depression and 1.93 (95% CI 1.16 to 3.21) for psychopathological symptoms. These associations also remained after additional adjustment. The overall effects are consistent yet small for ST/ST increment on mental health problems and its progression. Given the small effect size of the current results, it remains unclear the degree to which ST is a practically significant risk factor for mental health outcomes. Future studies of high quality are necessary to further examine this association and the direction of causality.
