美国青少年自杀率上升与社交媒体使用激增同时发生，一项新的分析认为两者或存在关联。
An increase in suicide rates among US teens occurred at the same time social media use surged and a new analysis suggests there may be a link.
美国联邦疾病控制预防中心的数据显示，在2010-2015年，青少年的自杀率有所上升，此前该数据已连降近二十年。
Suicide rates for teens rose between 2010 and 2015 after they had declined for nearly two decades, according to data from the US Federal Centers for Disease Control and Prevention.
该研究认为，其中一项因素可能是社交媒体使用的增加。
The study suggests that one factor could be rising social media use.
研究人员称，近期青少年自杀被归咎于“网络欺凌”，社交媒体贴文关于“完美”生活的描述可能正对青少年的身心健康造成极大的伤害。
Recent teen suicides have been blamed on cyberbullying, and social media posts depicting "perfect" lives may be taking a toll on teens' mental health, researchers say.
科罗拉多州利特尔顿一名名叫凯特琳·哈提的17岁高中生表示：“在经过几个小时的浏览Instagram之后，我感觉自己更糟了，因为我感到被遗忘了。”在当地几个青少年自杀事件发生后，他于上个月帮助组织了一次线下活动。
"After hours of scrolling through Instagram feeds, I just feel worse about myself because I feel left out," said Caitlin Hearty, a 17-year-old Littleton, Colorado, high school student who helped organize an offline campaign last month after several local teen suicides.
同样17岁的克洛伊·希林称：“没有人发布他们正在经历的不好的事情。”他目前在帮助数百名青少年同意在一个月内不使用互联网或社交媒体。
"No one posts the bad things they're going through," said Chloe Schilling, also 17, who helped with the campaign, in which hundreds of teens agreed not to use the internet or social media for one month.
该研究的作者、圣地亚哥州立大学心理学教授简·特翁戈表示：“我们不应该再认为智能手机无害。监督儿童对智能手机和社交媒体的使用，并加以合理的限制，这非常重要。”
"We need to stop thinking of smartphones as harmless. Monitoring kids' use of smartphones and social media is important, and so is setting reasonable limits," said study author Jean Twenge, a psychology professor at San Diego State University.
