The purpose of the current study was to explore the physical activity and screen time status among Chinese adolescents during the coronavirus disease (COVID-19) lockdown and their association with mood disturbance and conflicts with parents. A total of 1,680 7th to 12th grade students enrolled at a large middle-high school located in Southwest China completed an online survey measuring mood states, physical activity, screen time, conflicts with parents, and body height and weight. Physical activity, particularly of at least 150 minutes' duration each week, significantly decreased the likelihood of negative mood among adolescents during lock-down. Screen time, specifically other than that spent on online study, had a negative association with mood, after controlling for the relevant variables (i.e., physical activity and body mass index). Less screen time and accumulating 150 minutes of physical activity were associated with fewer conflicts with parents. With the continuing COVID-19 pandemic, local school districts, school leaders, and health professionals should develop greater awareness of potential problems with, and engage parents in developing specific guidance on controlling, screen time and promoting physical activity in a time-sensitive manner.

本研究旨在探讨新冠疫情封锁期间中国青少年的身体活动和屏幕时间状况，及其与情绪困扰和与父母冲突的关系。位于中国西南部的一所大型中学的 7 至 12 年级学生共 1680 人完成了一项在线调查，该调查测量了情绪状态、身体活动、屏幕时间、与父母的冲突以及身高和体重。身体活动，特别是每周至少 150 分钟的身体活动，显著降低了青少年在封锁期间出现负面情绪的可能性。在控制了相关变量（即身体活动和身体质量指数）后，屏幕时间，特别是除在线学习之外的时间，与情绪呈负相关。较少的屏幕时间和积累 150 分钟的身体活动与与父母的冲突较少有关。随着新冠疫情的持续，地方学区、学校领导和卫生专业人员应该更加关注屏幕时间和促进身体活动方面可能存在的问题，并让家长参与制定具体的指导意见，及时控制和推广这些问题。[(4), 14-20.]。
