To determine the associations between screen time across several contemporary screen modalities (eg, television, video games, text, video chat, social media) and adherence to the Mediterranean-DASH (dietary approaches to stop hypertension) intervention for neurodegenerative delay (MIND) diet in early adolescents. We analyzed data from the Adolescent Brain Cognitive Development study of 9 to 12-year-old adolescents in the United States. Multiple linear regression analyses examined the relationship between self-reported screen time measures at baseline (year 0) and the 1-year follow-up (year 1) and caregiver-reported nutrition assessments at year 1, providing a prospective and cross-sectional analysis. Cross-sectional marginal predicted probabilities were calculated. In a sample of 8267 adolescents (49.0% female, 56.9% white), mean age 10 years, total screen time increased from 3.80 h/d at year 0 to 4.61 h/d at year 1. Change in total screen time from year 0 and year 1 was associated with lower nutrition scores at year 1. Screen time spent on television, video games, and videos at year 0 was associated with lower nutrition scores at year 1. Screen time spent on television, video games, videos, texting, and social media at year 1 was associated with lower MIND diet scores at year 1. Both traditional (television) and several contemporary modalities of screen time are associated, prospectively and cross-sectionally, with lower overall diet quality, measured by the MIND diet nutrition score, in early adolescents. Future studies should further explore the effect of rising digital platforms and media on overall adolescent nutrition.

当代屏幕时间模式与青少年早期营养的关联

确定多种当代屏幕模式（例如电视、视频游戏、文本、视频聊天、社交媒体）的屏幕时间与坚持地中海 DASH（阻止高血压的饮食方法）神经退行性迟缓 (MIND) 饮食干预之间的关联在青少年早期。我们分析了针对美国 9 至 12 岁青少年的青少年大脑认知发展研究的数据。多元线性回归分析检查了基线（第 0 年）和 1 年随访（第 1 年）自我报告的屏幕时间测量值与护理人员报告的第 1 年营养评估之间的关系，提供了前瞻性和横断面分析。计算横截面边际预测概率。在 8267 名青少年（49.0% 女性，56.9% 白人）的样本中，平均年龄为 10 岁，总屏幕时间从第 0 年的 3.80 小时/天增加到第 1 年的 4.61 小时/天。从第 0 年开始总屏幕时间的变化第 1 年与第 1 年较低的营养得分相关。第 0 年在电视、视频游戏和视频上花费的屏幕时间与第 1 年较低的营养得分相关。在电视、视频游戏、视频、短信、第一年的社交媒体和第一年的 MIND 饮食得分较低与第一年较低的 MIND 饮食得分相关。传统（电视）和几种当代的屏幕时间方式，无论是前瞻性还是横向的，都与较低的整体饮食质量相关（通过 MIND 饮食营养来衡量）分数，在青少年早期。未来的研究应进一步探讨不断兴起的数字平台和媒体对青少年整体营养的影响。
