The literature has indicated that higher smoking media literacy (i.e., SML) can buffer adverse effects of exposure to pro-smoking media content (i.e., PMC) on smoking-related outcomes in adolescence. Thus, we aimed to investigate (a) SML levels among Korean adolescents and (b) relationships of SML with smoking behavior, attitudes, and susceptibility. In 2017, we collected cross-sectional data from nine middle or high schools in Korea, using a convenience sampling method (N = 476). For the first aim, we calculated the average score of SML. For the second aim, we conducted multinomial logistic regression (MLR), multiple linear regression, and binary multiple logistic regression. Additionally, we conducted Firth logistic regression and confirmed the robustness of our findings obtained from the MLR. The average SML score was 6.48 out of 10 points, indicating that our respondents’ average SML was slightly above the middle level. In addition, after adjusting for factors potentially affecting associations between SML and the three smoking-related outcomes, we found significant protective relationships of SML with all smoking-related outcomes: smoking behavior, attitudes, and susceptibility. Given our findings, the enhancement of SML through education should be considered an important strategy to weaken the link between exposure to PMC and smoking-related outcomes.

文献表明，较高的吸烟媒体素养（即 SML）可以缓冲接触有利于吸烟的媒体内容（即 PMC）对青春期吸烟相关结果的不利影响。因此，我们旨在调查 (a) 韩国青少年的 SML 水平和 (b) SML 与吸烟行为、态度和易感性的关系。2017 年，我们使用便利抽样方法（N = 476）收集了韩国九所初中或高中的横断面数据。对于第一个目标，我们计算了 SML 的平均分数。对于第二个目标，我们进行了多项逻辑回归 (MLR)、多元线性回归和二元多元逻辑回归。此外，我们进行了 Firth 逻辑回归，并证实了我们从 MLR 获得的结果的稳健性。平均 SML 分数为 6.48 分（满分 10 分），表明我们受访者的平均 SML 略高于中等水平。此外，在调整了可能影响 SML 与三种吸烟相关结果之间关联的因素后，我们发现 SML 与所有吸烟相关结果之间存在显着的保护关系：吸烟行为、态度和易感性。鉴于我们的研究结果，应将通过教育提高 SML 视为削弱 PMC 暴露与吸烟相关结果之间联系的重要策略。和易感性。鉴于我们的研究结果，应将通过教育提高 SML 视为削弱 PMC 暴露与吸烟相关结果之间联系的重要策略。和易感性。鉴于我们的研究结果，应将通过教育提高 SML 视为削弱 PMC 暴露与吸烟相关结果之间联系的重要策略。
