This study aimed to discover which young adults vape, the reasons given for vaping, and which reasons for vaping are associated with continued vaping/smoking.
In a UK cohort of 3,994 young adults, we explored the association of retrospectively-recalled reasons for vaping by 23 years (collected between 2015 and 2016) with vaping/smoking status at 24 years (collected between 2016 and 2017). Using logistic regression, we assessed the association with vaping behaviour among ever vapers who had ever smoked (n = 668), and with smoking behaviour among individuals who regularly smoked prior to vaping (n = 412).
Vaping to quit smoking was associated with higher likelihood of vaping (odds ratio [OR] = 3.51, 95 % confidence interval [95 % CI] = 2.29-5.38), but lower likelihood of smoking at 24 years (OR = 0.50, 95 %CI = 0.32 to 0.78). Vaping to cut down smoking was associated with higher likelihood of vaping (OR = 2.90, 95 % CI = 1.87-4.50) and smoking at 24 years (OR = 1.62, 95 % CI = 1.02-2.58). Vaping out of curiosity was associated with lower likelihood of vaping at 24 years (OR = 0.41, 95 %CI = 0.26 to 0.63) but higher likelihood of smoking at 24 years (OR = 1.66, 95 % CI = 1.04-2.65).
Intention to quit appears important for young adults to stop smoking using e-cigarettes. Public health strategies that encourage vaping specifically for smoking cessation may encourage quitting among young adults.
本研究旨在发现哪些年轻人吸电子烟，他们吸电子烟的原因，以及哪些吸电子烟的原因与继续吸电子烟/吸烟有关。
在英国的一个 3994 名年轻人队列中，我们通过 23 年（收集于 2015 年至 2016 年之间）的回顾性调查，探讨了与 24 年（收集于 2016 年至 2017 年之间）吸电子烟/吸烟状况相关的吸电子烟原因。我们使用逻辑回归，评估了在曾吸过烟的吸电子烟者中（n = 668），与吸电子烟行为相关的原因，以及在在开始吸电子烟之前定期吸烟的个体中（n = 412），与吸烟行为相关的原因。
吸电子烟以戒烟与更高的吸电子烟可能性相关（比值比 [OR] = 3.51，95 %置信区间 [95 % CI] = 2.29-5.38），但与 24 年的吸烟可能性较低相关（OR = 0.50，95 %CI = 0.32 至 0.78）。吸电子烟以减少吸烟量与更高的吸电子烟可能性相关（OR = 2.90，95 % CI = 1.87-4.50）和 24 年的吸烟可能性相关（OR = 1.62，95 % CI = 1.02-2.58）。出于好奇而吸电子烟与 24 年的吸电子烟可能性较低相关（OR = 0.41，95 %CI = 0.26 至 0.63），但与 24 年的吸烟可能性较高相关（OR = 1.66，95 % CI = 1.04-2.65）。
对于年轻人来说，意图戒烟似乎很重要，他们可以使用电子烟来戒烟。鼓励专门为戒烟而吸电子烟的公共卫生策略可能会鼓励年轻人戒烟。
