背景：年轻人花在屏幕上的时间比除了睡觉之外的任何活动都多。屏幕时间是肥胖的一个危险因素，可能是因为食品和饮料广告对饮食的影响。目的：我们试图评估屏幕时间[即，电视，电子游戏，数字多功能光盘（DVD）/视频和总屏幕时间]与低营养质量食品（FLNQ）消费量的2年变化的纵向关系，这些食品通常在屏幕上做广告[即，含糖饮料、快餐、甜食、咸味小吃以及这些食物的总和（总FLNQ）]以及水果和蔬菜。使用2004年、2006年和2008年的《今日成长研究H》，该研究包括2004年9-16岁的6002名女性和4917名男性青少年，我们评估了与2年饮食变化相关的筛查时间（变化和基线）。回归模型包括4604名女孩和3668名男孩，完整的屏幕时间和饮食数据>= 2个连续的questionnaire.Results：每天每增加一小时的电视，电子游戏，DVD/视频与总FLNQ摄入量的增加相关（范围：0.10-0.28份/d; P < 0.05）。每天总屏幕时间每增加一小时，含糖饮料、快餐、甜食和咸味小吃的摄入量就会增加（范围：0.02-0.06份/天; P < 0.001），水果和蔬菜的摄入量就会减少（范围：-0.05至-0.02份/天; P < 0.05）。基线时更长的屏幕时间（男孩的电子游戏除外）与随后的总FLNQ摄入量增加相关，基线时更长的屏幕时间（DVD/视频除外）与水果和蔬菜摄入量减少相关（P < 0.05）。在性别和食物组和敏感性分析，电视是最一贯与饮食changes.Conclusions：屏幕时间的增加与增加消费的食物和饮料的低营养质量和减少水果和蔬菜的消费。我们的研究结果警告说，不要过度使用屏幕媒体，特别是电视，在青年。
Background: Youth spend more time with screens than any activity except sleeping. Screen time is a risk factor for obesity, possibly because of the influence of food and beverage advertising on diet.Objective: We sought to assess longitudinal relations of screen time [ie, television, electronic games, digital versatile discs (DVDs)/videos, and total screen time] with the 2-y changes in consumption of foods of low nutritional quality (FLNQ) that are commonly advertised on screens [ie, sugar-sweetened beverages, fast food, sweets, salty snacks, and the sum of these foods (total FLNQ)] and fruit and vegetables.Design: With the use of 2004, 2006, and 2008 waves of the Growing Up Today Study H, which consisted of a cohort of 6002 female and 4917 male adolescents aged 9-16 y in 2004, we assessed screen time (change and baseline) in relation to the 2-y dietary changes. Regression models included 4604 girls and 3668 boys with complete screen time and diet data on >= 2 consecutive questionnaires.Results: Each hour-per-day increase in television, electronic games, and DVDs/videos was associated with increased intake of total FLNQ (range: 0.10-0.28 servings/d; P < 0.05). Each hour-per-day increase in total screen time predicted increased intakes of sugar-sweetened beverages, fast food, sweets, and salty snacks (range: 0.02-0.06 servings/d; P < 0.001) and decreased intakes of fruit and vegetables (range: -0.05 to -0.02 servings/d; P < 0.05). Greater screen time at baseline (except electronic games in boys) was associated with subsequent increased intake of total FLNQ, and greater screen time at baseline (except DVDs/videos) was associated with decreased intake of fruit and vegetables (P < 0.05). Across sex and food groups and in sensitivity analyses, television was most consistently associated with dietary changes.Conclusions: Increases in screen time were associated with increased consumption of foods and beverages of low nutritional quality and decreased consumption of fruit and vegetables. Our results caution against excessive use of screen media, especially television, in youth.
