JAMA Pediatr:“屏幕时间”与青少年抑郁风险

2019-07-17 MedSci MedSci原创

研究认为,青少年过多的使用社交媒体、电视和网络导致抑郁风险增加

有证据怀疑青少年屏幕时间(社交媒体、电视、视频游戏和计算机使用)与抑郁症状风险增加有关,近日研究人员就二者的关系进行了考察。

大蒙特利尔地区31所学校的7年级青少年参与本次研究,随访4年。独立变量包括社交媒体、电视、视频游戏和计算机使用。结果是抑郁症状。

共有3826名青少年(1798名女孩[47%];平均年龄12.7岁)。参与者抑郁症状每年增加(第1年平均得分为4.29分;第4年平均为5.45分)。使用社交媒体的每增加一小时,青少年抑郁症状得分增加0.64个单位,计算机使用的水平与抑郁之间存在相似的关联(0.69)。随机研究发现任意一年中,社交媒体使用再增加一小时,同年抑郁症状得分再增加0.41个单位。电视节目中也发现了类似的关联(0.18)。

研究认为,青少年过多的使用社交媒体、电视和网络导致抑郁风险增加。
