The popularity of electronic cigarettes (e-cigarettes) has increased worldwide among youth, even in countries like Mexico that ban them. This study aimed to assess the correlates of e-cigarette use frequency among Mexican students who currently use ecigarettes, as well as to describe their reasons for use.
Data were analyzed from a school-based survey of 57 public middle schools from the three largest cities in Mexico. Primary analyses were confined to those who used e-cigarettes in the prior 30 days. Censored binomial models for truncated distributions were estimated, regressing lifetime and past month frequency of use on participant sociodemographics, other substance use (smoking, alcohol, drugs), technophilia (appeal of new technologies), characteristics of e-cigarettes used, and family's and friends' use of nicotine products.
Being male (APR = 1.93 95% CI 1.53-2.44), using drugs, (APR = 1.51 95% CI 1.03-2.20), higher technophilia (APR = 1.66 CI 1.21-2.29) and having a family member who uses e-cigarettes and cigarettes were associated with more frequent use in the last month. Students who preferred fruit and combined flavors had used e-cigarettes more often in their lifetime compared to students who preferred mint/menthol flavors.
Some risk factors for more frequent e-cigarette use among Mexican youth are similar to those foudn in other countries (having relatives who use ecigarettes, using drugs, and use of fruit flavors). Additionally, the novel measure of technophilia was positively associated with frequency of e-cigarette use. The appeal of flavors, in particular, suggests the importance of reducing youth access to flavored products to impede product initiation and progression.
电子烟（e-cigarettes）在全球范围内，尤其是在像墨西哥这样禁止电子烟的国家，在青少年中越来越受欢迎。本研究旨在评估目前使用电子烟的墨西哥学生中电子烟使用频率的相关因素，以及描述他们使用电子烟的原因。
数据来自墨西哥三个最大城市的 57 所公立中学的一项基于学校的调查。主要分析仅限于过去 30 天内使用过电子烟的学生。使用截断分布的 censored binomial 模型进行估计，将终生和过去一个月的使用频率回归到参与者的社会人口统计学、其他物质使用（吸烟、饮酒、吸毒）、技术喜好（新技术的吸引力）、使用的电子烟特征以及家人和朋友使用尼古丁产品上。
男性（APR=1.93 95%CI 1.53-2.44）、使用毒品（APR=1.51 95%CI 1.03-2.20）、更高的技术喜好（APR=1.66 CI 1.21-2.29）以及有使用电子烟和香烟的家庭成员与过去一个月更频繁的使用有关。与更喜欢薄荷/薄荷醇口味的学生相比，更喜欢水果和混合口味的学生更经常使用电子烟。
一些与墨西哥青少年更频繁使用电子烟有关的风险因素与其他国家相似（有使用电子烟的亲戚、使用毒品以及使用水果口味）。此外，技术喜好的新颖衡量标准与电子烟使用频率呈正相关。特别是口味的吸引力表明，减少青少年获得调味产品的机会对于阻止产品的引入和发展非常重要。
