美国有线新闻 CNN 研究建议青少年减少屏幕使用时间（在线收听）

A new study out of Canada suggests teenagers should spend less time looking at screens and more time involved in activities. The findings published in the journal Preventive Medicine were based on a survey of 28,000 7th graders in British Columbia. They answered questions about how much time they spent watching TV, streaming videos, playing video games versus how much time they spent in extracurricular activities like sports and music programs. Then they ranked how good they felt about each day when they woke up. From their answers, researchers concluded that teens who spent more time in activities were mentally healthier and less anxious and depressed than those who spent more time with screens.

加拿大一项新研究建议，青少年应该减少屏幕使用时间，增加活动时间。这项研究发表在《预防医学》期刊上，研究结果基于对不列颠哥伦比亚省2.8万名7年级学生的调查所得出。他们回答的问题包括：在看电视、流媒体视频、玩电子游戏上所用的时间，以及在体育和音乐等课外活动上所花的时间。之后，研究人员让他们对自已每天醒来后的感觉进行排序。根据他们的回答，研究人员得出结论：与那些将更多时间花在屏幕上的青少年相比，在活动上花时间更多的青少年心理更健康，焦虑和抑郁也更少。

And the study suggested that extra screen time was especially harmful to girls. For them, researchers say the negative effects were stronger. So how much screen time is too much? The Canadian Pediatric Society says all adolescents should have less than two hours of screen time per day and that guideline factored into the study. But it's important to point out that the information for it was gathered between 2014 and 2018, years before the coronavirus pandemic hit.

研究表明，过多的屏幕时间对女孩尤其有害。研究人员表示，女孩受到的负面影响更大。那多少屏幕时间算过多呢？加拿大儿科学会表示，所有青少年每天的屏幕时间应该少于两小时，这一指导原则也被纳入研究中。但有必要指出的是，这些信息的收集时间为2014年至2018年期间，也就是冠状病毒大流行爆发的前几年。

And this year, with fewer opportunities to see friends and participate in extracurricular events, teenagers have shown higher levels of depression and anxiety according to other research. The lead author of the Canadian study says even though it's harder to do it's still important to find ways for teens to safely get involved with programs and hobbies away from screens.

另一项研究显示，今年，由于与朋友见面和参加课外活动的机会减少，青少年表现出更高程度的抑郁和焦虑。这项加拿大研究的主要作者表示，尽管很难做到，但找到让青少年安全参与远离屏幕的活动和爱好的方法仍然很重要。
