Social media may influence children and young people's health behaviour, including cigarette and e-cigarette use.
We analysed data from participants aged 10-25 years in the UK Household Longitudinal Study 2015-2021. The amount of social media use reported on a normal weekday was related to current cigarette smoking and e-cigarette use. Generalised estimating equation (GEE) logistic regression models investigated associations of social media use with cigarette smoking and e-cigarette use. Models controlled for possible confounders including age, sex, country of UK, ethnicity, household income and use of cigarette/e-cigarettes by others within the home.
Among 10 808 participants with 27 962 observations, current cigarette smoking was reported by 8.6% of participants for at least one time point, and current e-cigarette use by 2.5% of participants. In adjusted GEE models, more frequent use of social media was associated with greater odds of current cigarette smoking. This was particularly apparent at higher levels of use (eg, adjusted odds ratio (AOR) 3.60, 95% CI 2.61 to 4.96 for ≥7 hours/day vs none). Associations were similar for e-cigarettes (AOR 2.73, 95% CI 1.40 to 5.29 for ≥7 hours/day social media use vs none). There was evidence of dose-response in associations between time spent on social media and both cigarette and e-cigarette use (both p<0.001). Analyses stratified by sex and household income found similar associations for cigarettes; however, for e-cigarettes associations were concentrated among males and those from higher household income groups.
Social media use is associated with increased risk of cigarette smoking and e-cigarette use. There is a need for greater research on this issue as well as potential policy responses.
社交媒体可能会影响儿童和青少年的健康行为，包括吸烟和电子烟的使用。
我们分析了 2015-2021 年英国家庭纵向研究中年龄在 10-25 岁的参与者的数据。报告的工作日社交媒体使用量与当前吸烟和电子烟使用有关。广义估计方程（GEE）逻辑回归模型调查了社交媒体使用与吸烟和电子烟使用的关联。模型控制了可能的混杂因素，包括年龄、性别、英国国家、种族、家庭收入以及家庭中其他人吸烟/电子烟的情况。
在 10808 名参与者中，有 27962 次观察，至少有一次报告当前吸烟的参与者占 8.6%，当前使用电子烟的参与者占 2.5%。在调整后的 GEE 模型中，更频繁地使用社交媒体与更高的当前吸烟几率相关。这种关联在更高的使用水平下更为明显（例如，每天使用社交媒体≥7 小时与从不使用相比，调整后的比值比（AOR）为 3.60，95%可信区间（CI）为 2.61 至 4.96）。对于电子烟，关联也相似（每天使用社交媒体≥7 小时与从不使用相比，AOR 为 2.73，95%CI 为 1.40 至 5.29）。在社交媒体使用时间与吸烟和电子烟使用之间的关联中存在剂量-反应关系（均 p<0.001）。按性别和家庭收入分层的分析发现，吸烟的关联相似；然而，对于电子烟，关联主要集中在男性和高收入家庭群体中。
社交媒体使用与吸烟和电子烟使用的风险增加有关。需要对此问题进行更多研究以及潜在的政策回应。
