To describe electronic media exposure and its associations with beverage intake among United States high school students.
School-based survey data from a nationally representative sample of 9th- through 12th-grade students from the National Youth Physical Activity and Nutrition Study were analyzed using chi-square and multivariate logistic analyses.
On an average school day, 23.5% of students used a computer or played video/computer games ≥ 3 h/d, 28.3% watched television (TV) ≥ 3 h/d, 79.9% had ≥ 3 TVs in the home, 70.2% had a TV in their bedroom, and 41.0% most of the time or always had a TV on while eating dinner at home. Students with high media exposure were more likely to drink sugar-sweetened beverages ≥ 3 times per day and less likely to drink water ≥ 3 times per day and drink ≥ 2 glasses of milk per day.
Efforts to reduce sugar-sweetened beverage intake among adolescents may include limiting exposure to electronic media.
描述美国高中生的电子媒体接触情况及其与饮料摄入的关联。
对全国青少年体力活动和营养研究中来自 9 至 12 年级的具有代表性的学生样本进行基于学校的调查数据，使用卡方检验和多变量逻辑分析进行分析。
在平均上学日，23.5%的学生每天使用计算机或玩视频/电脑游戏≥3 小时，28.3%每天看电视（TV）≥3 小时，79.9%的家庭有≥3 台电视，70.2%的学生卧室里有电视，41.0%的学生在家里吃晚餐时经常或总是开着电视。媒体接触度高的学生更有可能每天饮用含糖饮料≥3 次，而每天饮水≥3 次和每天饮用≥2 杯牛奶的可能性较小。
减少青少年含糖饮料摄入量的努力可能包括限制电子媒体的接触。
