旨在量化流行的当代YouTube音乐视频中的烟草和酒精内容，包括品牌;并测量青少年对此类内容的接触。在2013/14年的12周内，对所有英国前40名YouTube音乐视频中的酒精、烟草或电子烟图像进行10秒间隔内容分析;对32个最受欢迎的高内容视频的青少年观看情况进行在线全国调查。背景是大不列颠。研究对象：2068名11-18岁的青少年完成了一项在线调查。测量酒精、烟草和电子烟的使用、暗示使用、随身用品或音乐视频中的品牌以及观看过抽样视频的青少年的比例和估计人数。所有视频中，45%（95%置信区间（CI）= 33-51%）出现了酒精图像，22%（95% CI= 13-27%）出现了烟草图像，2%（95% CI= 0-4%）出现了电子烟图像。酒精品牌出现在7%（95% CI= 2-11%）的视频中，烟草品牌出现在4%（95% CI= 0-7%），电子烟出现在1%（95% CI= 0-3%）。最常见的酒精，烟草和电子烟品牌分别是Absolut Tune，万宝路和E-Lites。81%（95% CI= 79%，83%）的受访青少年至少观看过32个最受欢迎的含有酒精或烟草内容的音乐视频中的一个，其中87%（95% CI= 85%，89%）的青少年至少重新观看过一个视频。平均观看视频数量为7.1（95% CI= 6.8，7.4）。女孩比男孩更有可能观看和重新观看视频，P< 0.001。大量英国青少年，特别是女孩，观看的流行YouTube音乐视频包含大量烟草和酒精内容，包括品牌。
Aims To quantify tobacco and alcohol content, including branding, in popular contemporary YouTube music videos; and measure adolescent exposure to such content. Design Ten-second interval content analysis of alcohol, tobacco or electronic cigarette imagery in all UK Top 40 YouTube music videos during a 12-week period in 2013/14; on-line national survey of adolescent viewing of the 32 most popular high-content videos. Setting Great Britain. Participants A total of 2068 adolescents aged 11-18 years who completed an on-line survey. Measurements Occurrence of alcohol, tobacco and electronic cigarette use, implied use, paraphernalia or branding in music videos and proportions and estimated numbers of adolescents who had watched sampled videos. Findings Alcohol imagery appeared in 45% [95% confidence interval (CI)= 33-51%] of all videos, tobacco in 22% (95% CI= 13-27%) and electronic cigarettes in 2% (95% CI= 0-4%). Alcohol branding appeared in 7% (95% CI= 2-11%) of videos, tobacco branding in 4% (95% CI= 0-7%) and electronic cigarettes in 1% (95% CI= 0-3%). The most frequently observed alcohol, tobacco and electronic cigarette brands were, respectively, Absolut Tune, Marlboro and E-Lites. At least one of the 32 most popular music videos containing alcohol or tobacco content had been seen by 81% (95% CI= 79%, 83%) of adolescents surveyed, and of these 87% (95% CI= 85%, 89%) had re-watched at least one video. The average number of videos seen was 7.1 (95% CI= 6.8, 7.4). Girls were more likely to watch and also re-watch the videos than boys, P< 0.001. Conclusions Popular YouTube music videos watched by a large number of British adolescents, particularly girls, include significant tobacco and alcohol content, including branding.
