Low- and middle-income countries have increasingly banned e-cigarettes, as in Mexico. In these countries, little is known about where adults obtain e-cigarettes or who uses e-cigarettes with nicotine.
Data were analyzed from eight online surveys of Mexican adults who both smoked and used e-cigarettes (November 2018-March 2021; n = 2,060). For the e-cigarette they used most often, participants reported how they acquired it (social sources=reference; online purchase; vape shop purchase; other retail purchase) and if it contained nicotine (no=reference group; yes; don't know). Multinomial models regressed each of these outcomes on smoking- and e-cigarette-related factors, as well as sociodemographics.
Almost half the sample (45.9 %) reported obtaining their e-cigarettes from social sources, with online purchase being the second most common source (28.7 %). Being male, having recently attempted to quit smoking, and more frequent e-cigarette use were positively associated with purchasing e-cigarettes (vs social sources) across all venues. Most reported that their e-cigarettes contained nicotine (58.2 %), a third reported using e-cigarettes without nicotine (35.9 %), and some did not know (5.8 %). More frequent smoking and e-cigarette use, using closed e-cigarette devices and purchasing e-cigarettes online were positively associated with using e-cigarettes with nicotine.
Despite Mexico's e-cigarette ban, adults who smoke access e-cigarettes through multiple sources, including online and vape shop purchases. Most participants reported using e-cigarettes with nicotine, though many did not or did not know.
中低收入国家(如墨西哥)已越来越多地禁止电子烟。在这些国家,人们对成年人从何处获得电子烟或谁使用含尼古丁的电子烟知之甚少。
对 2018 年 11 月至 2021 年 3 月期间参加过 8 项在线调查的 2060 名既吸烟又使用电子烟的墨西哥成年人的数据进行了分析(n=2060)。对于他们最常使用的电子烟,参与者报告了他们是如何获得的(社交来源=参考;在线购买;电子烟店购买;其他零售店购买),以及电子烟是否含有尼古丁(否=参考组;是;不知道)。多变量模型根据与吸烟和电子烟相关的因素以及社会人口统计学因素,对这些结果中的每一个进行了回归。
样本中近一半(45.9%)的人报告从社交来源获得电子烟,其次是在线购买(28.7%)。男性、最近试图戒烟以及更频繁地使用电子烟与所有场所购买电子烟(而非社交来源)呈正相关。大多数人报告他们的电子烟含有尼古丁(58.2%),三分之一的人报告使用不含尼古丁的电子烟(35.9%),还有一些人不知道(5.8%)。更频繁的吸烟和使用电子烟、使用封闭式电子烟设备和在线购买电子烟与使用含尼古丁的电子烟呈正相关。
尽管墨西哥禁止电子烟,但吸烟的成年人可以通过多种途径获得电子烟,包括在线和电子烟店购买。大多数参与者报告使用含尼古丁的电子烟,但也有许多人不知道或不知道。
