Media forms an important part of the lives of adolescents in as much as the shows they watch on television, playing video games, as well as visiting the various websites. There is a growing concern of the influence of media on every aspect of health of children and adolescents. About 95% of the population in India has availability of television. India has limited studies which have explored the use of screen-based media (SBM) and its effect on child health. This study was conducted to assess the pattern of SBM use.
A community-based cross-sectional study was conducted in an Urban Resettlement Colony, New Delhi. The study included 550 adolescents of age group from 10 to 19 years of age selected through simple random sampling from a list of adolescents residing in the area. A semi-structured interview schedule was used.
About 98% of the adolescents used SBM. Television formed the maximum used media (96.5%). The mean (standard deviation) of the screen time was found to be 3.8 (2.77) h/day. Out of the total screen time, time contributed by television is 2.8 h/day followed by other SBM. About 68% of adolescents reported having screen time more than the recommended (>2 h). Significant association was observed between screen time and watching television while eating [odds ratio (95% confidence interval) = 0.35 (0.22, 0.55)].
High proportion of adolescents use SBM for more than the recommended screen time. We should have a recommendation for maximum screen time separately for developing countries.
媒体在青少年生活中占据重要部分，包括他们观看的电视节目、玩的电子游戏以及浏览的各类网站。媒体对儿童和青少年健康各个方面的影响日益受到关注。印度约95%的人口能够收看电视。印度对基于屏幕的媒体（SBM）的使用及其对儿童健康的影响的研究有限。本研究旨在评估SBM的使用模式。
在新德里的一个城市安置区开展了一项基于社区的横断面研究。该研究纳入了550名年龄在10至19岁之间的青少年，他们通过简单随机抽样从该地区青少年名单中选取。使用了半结构化访谈提纲。
约98%的青少年使用SBM。电视是使用最多的媒体（96.5%）。屏幕时间的均值（标准差）为3.8（2.77）小时/天。在总屏幕时间中，电视贡献的时间为2.8小时/天，其次是其他SBM。约68%的青少年报告屏幕时间超过推荐时长（>2小时）。在屏幕时间与吃饭时看电视之间观察到显著关联[比值比（95%置信区间）=0.35（0.22，0.55）]。
高比例的青少年使用SBM的时间超过推荐的屏幕时间。我们应该针对发展中国家分别制定屏幕时间上限的建议。
