Latin America has the highest prevalence of tobacco use by youth. Higher media literacy, defined as the ability to analyze and evaluate media messages, has been associated with lower smoking among youth in the United States. The objective of this study was to determine whether media literacy related to smoking is independently associated with current smoking and susceptibility to future smoking in a sample of mostly indigenous youth in Jujuy, Argentina.
In 2006, a self-administered survey was conducted among 10th grade students sampled from 27 randomly selected urban and rural schools in Jujuy. Survey items measured smoking behavior (ever, never, and current), susceptibility to future smoking among never-smokers (definitely not accept a cigarette from a friend or to smoke in the future), 5 items assessing smoking media literacy (SML), and risk factors for smoking.
Of the 3,470 respondents, 1,170 (34%) reported having smoked in the previous 30 days (current). Of the 1,430 students who had never smoked, 912 (64%) were susceptible to future smoking. High media literacy was present in 38%. Using multiple logistic regression, fully adjusted models showed that high media literacy was significantly associated as a protective factor of being a current smoker (odds ratio [OR] = 0.81; 95% CI = 0.67-0.97) and of being susceptible to future smoking (OR = 0.73; 95% CI = 0.58-0.92) among those who had never smoked.
Among youth in Jujuy, higher SML was significantly associated with both lower current smoking and susceptibility to future smoking. Teaching SML may be a valuable component in a prevention intervention in this population.
拉丁美洲的青少年吸烟率最高。更高的媒体素养，即分析和评估媒体信息的能力，与美国青少年吸烟率较低有关。本研究的目的是确定在阿根廷胡胡伊省的一个主要是土着青年样本中，与吸烟有关的媒体素养是否与当前吸烟和未来吸烟的易感性独立相关。
2006 年，对胡胡伊省 27 所随机选择的城市和农村学校的 10 年级学生进行了一项自我管理的调查。调查项目衡量了吸烟行为（曾经、从不、当前）、从不吸烟者未来吸烟的易感性（绝对不会接受朋友的香烟或未来吸烟）、衡量吸烟媒体素养的 5 项指标（SML）和吸烟的危险因素。
在 3470 名应答者中，有 1170 名（34%）报告在过去 30 天内吸烟（当前）。在 1430 名从未吸烟的学生中，有 912 名（64%）对未来吸烟有易感性。高媒体素养的比例为 38%。使用多变量逻辑回归，完全调整的模型显示，高媒体素养与当前吸烟（比值比[OR] = 0.81；95%可信区间[CI] = 0.67-0.97）和未来吸烟易感性（OR = 0.73；95% CI = 0.58-0.92）作为从不吸烟者的保护因素显著相关。
在胡胡伊省的青少年中，较高的 SML 与当前吸烟率和未来吸烟易感性都显著相关。教授 SML 可能是该人群预防干预的一个有价值的组成部分。
