Electronic device use and beverage related sugar and caffeine intake in US adolescents

BackgroundDespite recent declines in consumption of sugary beverages, energy drinks (ED) and sodas continue to contribute a substantial amount of sugar and caffeine to the diet of youth. Consumption of these beverages has been linked with electronic device use, however in-depth associations between sugar and caffeine intake from energy drinks and sodas with various electronic devices are not clear.ObjectiveDescribe the relationship of soda and energy drink consumption and associated added sugar and caffeine intake with electronic device use among adolescents.MethodsSecondary data from the 2013–2016 cycles of Monitoring the Future Survey, a national, repeated, cross-sectional study, were analyzed. Information on energy drink and soda consumption by students in grades 8 and 10 (n = 32,418) from 252–263 schools randomly sampled from all US states was used.ResultsSoda and energy drink consumption decreased each year from 2013–2016 while daily use of electronic devices remained stable. An additional hour/day of TV was linked to a 6.92g (6.31,7.48; pConclusionWhile a trend towards reduced energy drink and soda intake from 2013–2016 was evident, greater electronic device use, especially TV time, was linked to higher intake of beverage-derived added sugar and caffeine amongst adolescents. Addressing these behaviours through counselling or health promotion could potentially help to reduce excess sugar and caffeine intake from sodas and energy drinks among this population.研究背景 尽管近年来含糖饮料的消费量有所下降，但能量饮料（energy drinks，ED）与苏打汽水仍在青少年的日常膳食中贡献了大量的糖与咖啡因。此类饮料的摄入与电子设备使用行为存在关联，但目前尚不清楚能量饮料与苏打汽水中摄入的糖、咖啡因，与各类电子设备使用之间的深层关联。 研究目的 阐明青少年群体中，苏打汽水与能量饮料的摄入情况，及其伴随的添加糖与咖啡因摄入量，与电子设备使用行为之间的关联。 研究方法 本研究分析了2013-2016年周期的「监测未来调查（Monitoring the Future Survey）」的二级数据，该调查为一项全国性重复横断研究。研究纳入了从全美各州随机抽取的252至263所学校的8年级与10年级学生（共32418名）的能量饮料与苏打汽水摄入相关信息。 研究结果 2013-2016年间，苏打汽水与能量饮料的年消费量逐年下降，而电子设备的日均使用量则保持稳定。日均每多观看1小时电视，与6.92g的额外摄入相关（95%置信区间：6.31~7.48；p[原文未完整显示]）。 研究结论 尽管2013-2016年间青少年的能量饮料与苏打汽水摄入呈下降趋势，但电子设备使用时长越长，尤其是看电视的时间越长，其从饮料中摄入的添加糖与咖啡因量越高。通过咨询指导或健康宣传干预此类行为，或可帮助该群体减少从苏打汽水与能量饮料中摄入过量的糖与咖啡因。
