研究发现,在与更差的ADHD症状和迟缓的大脑发育有关的儿童中,屏幕时间较高。 High screen time in kids linked to worse ADHD symptoms and slower brain development, study finds.

屏幕时间较长的儿童更有可能出现严重的ADHD症状,这是美国对超过11 000名9岁和10岁儿童进行的一项大型研究。 Children with higher screen time are more likely to develop severe ADHD symptoms, a large U.S.-based study of over 11,000 nine- and ten-year-olds found. 在两年多的时间里,即使计算了初始水平后,屏幕使用量增加,预测多动症多动症症状会恶化。 Over two years, increased screen use predicted worse ADHD symptoms, even after accounting for initial levels. 核磁共振扫描显示,大脑体积较小,包括右表层和总体皮下体积,以及大脑区域与认知有关的发育较慢。 MRI scans showed smaller brain volumes, including in the right putamen and overall cortical volume, along with slower development in brain regions linked to cognition. 研究人员认为,过量的屏幕接触可能会推迟大脑成熟期,从而形成像ADHD一样的特征。 Researchers suggest excessive screen exposure may delay brain maturation, contributing to ADHD-like patterns. 调查结果发表在《翻译精神病学》中,突出说明有必要制定筛选时间准则,以保护儿童神经和心理健康。 The findings, published in Translational Psychiatry, highlight the need for screen time guidelines to protect children's neurological and mental health.
