JAMA子刊:年纪轻轻觉得自己“又胖又丑”?请远离这个隐形“PUA杀手”——手机与社交网络!

2022-05-23 liangying MedSci原创

使用智能手机的持续时间和通过智能手机访问最多的内容类型与青少年的身体形象自我认知偏差和减肥行为有关。

在过去十年中,全球智能手机用户数量迅速增长。如今,智能手机已成为一种主要的屏幕设备,用于访问各种媒体内容,包括社交媒体(如Instagram和Facebook)、视频(如YouTube和Netflix)、游戏和音乐等。智能手机还可以方便地进行快速信息搜索,促进社交互动。

在智能手机用户中,青少年是使用智能手机时间最长的,也是过度依赖智能手机风险最高的。鉴于青少年越来越多地使用智能手机,家长们开始对其负面影响表示担忧。一些研究报告称,过度使用智能手机与抑郁、睡眠不足、低质量睡眠以及青少年社交问题有关。由于青春期是心理和行为发展的敏感期,青春期使用智能手机也可能与心理健康和相关行为有关。然而,人们对智能手机的使用与其他心理结果和相关健康行为的关系知之甚少,包括身体形象自我认知偏差(BID)和不适当的减肥尝试。

本研究探索了青少年使用智能手机的持续时间和通过智能手机访问最多的内容类型与身体形象自我认知偏差及减肥行为的关系。

这项横断面研究使用了2017年基于人群的韩国青少年风险行为网络调查的数据。参与者包括53名具有全国代表性的样本,共133名年龄在12至18岁之间的韩国青少年。数据收集时间为2017年6月1日-7月18日。分析时间为2020年2月7日至2022年3月30日。

主要结局为:身体形象自我认知偏差(对体重的过度感知)、减肥尝试、使用不当的减肥策略(不吃饭、一次只吃一种食物、呕吐或使用泻药)以及健康的减肥行为(肌肉强化和有氧运动)。进行多变量logistic回归分析以估计优势比(ORs)和95%可信区间,考虑调查抽样和调整潜在混杂因素。

在最后纳入的53133名参与者中,平均年龄(SD)为15.0(1.8)岁,50.7%的参与者为女性,49.3%为男性。在调整了访问内容的类型后发现,无论男女,长时间使用智能手机(301分钟/天)与身体形象自我认知偏差和不适当的减肥策略均呈正相关。

青少年智能手机内容与身体形象自我认知偏差和减肥行为的关系

在调整了智能手机的使用时间后,与主要用于教育或信息内容的智能手机相比,用于视频、电影或音乐、网络卡通或网络小说以及游戏的智能手机与男孩的身体形象自我认知偏差呈正相关。在男孩中,主要用于聊天、发消息或发电子邮件的智能手机与肌肉强化活动和有氧运动呈正相关。在女孩中,使用智能手机主要用于聊天、发信息或发电子邮件与减肥尝试和使用不适当的减肥策略呈正相关,使用智能手机主要用于社交网络服务或论坛也是如此。

总之,在这项横断面研究中,使用智能手机的持续时间和通过智能手机访问最多的内容类型与青少年的身体形象自我认知偏差和减肥行为有关。这些发现表明,需要制定相关策略以帮助青少年发展健康的智能手机使用行为。
