Young people are more likely to have experimented with e-cigarettes (e-cigs) compared with older adults. Few studies identify reasons for experimentation/use of e-cigs among young people; we sought to discover what drives college students to use e-cigs.
Undergraduate students (ages 18-23) at four universities in New York State were surveyed. Among e-cig ever users (n=429), reasons for use were examined. A multinomial logistic regression model analyzed the relative risk of reasons for using e-cigs among discontinued, current non-daily and current daily e-cig users.
Using e-cigs for enjoyment was associated with current non-daily (RR=2.11, 95% CI=1.18-3.75) and current daily use (RR=19.1, 95% CI=3.71-98.54). Non-daily use was related to use because e-cigs are less toxic than cigarettes (RR=2.80, 95% CI=1.75-4.50). More daily users reported use to quit smoking compared with either non-daily or discontinued users (53.3% vs. 12.2% and 13.3%, respectively; p<0.05). Among current users, 72.3% used for enjoyment, compared with 42.9% of discontinued users (p<0.05).
In contrast to adults, who often report e-cig use to quit smoking, young people are less likely to use for this reason. The exception was daily e-cig users, who often reported use for quitting/reduction of smoking. Rather, college students report usage reasons related to affect (e.g. enjoyment). Overall, enjoyment was reported more often than was use for quitting smoking; affective reasons likely play a role in the popularity of e-cigs and should be considered in future assessments of e-cig users.
与年长者相比，年轻人尝试电子烟的可能性更大。很少有研究确定年轻人尝试/使用电子烟的原因；我们试图找出促使大学生使用电子烟的因素。
对纽约州四所大学的本科生（年龄在18 - 23岁之间）进行了调查。在曾经使用过电子烟的人群（n = 429）中，研究了使用原因。采用多项逻辑回归模型分析了在已停止使用、当前非每日使用和当前每日使用电子烟的人群中，使用电子烟原因的相对风险。
为了享受而使用电子烟与当前非每日使用（相对风险 = 2.11，95%置信区间 = 1.18 - 3.75）和当前每日使用（相对风险 = 19.1，95%置信区间 = 3.71 - 98.54）相关。非每日使用与认为电子烟比香烟毒性小有关（相对风险 = 2.80，95%置信区间 = 1.75 - 4.50）。与非每日使用者或已停止使用者相比，更多的每日使用者表示使用电子烟是为了戒烟（分别为53.3%、12.2%和13.3%；p < 0.05）。在当前使用者中，72.3%是为了享受而使用，而已停止使用者中这一比例为42.9%（p < 0.05）。
与经常报告使用电子烟来戒烟的成年人不同，年轻人因这个原因使用电子烟的可能性较小。每日使用电子烟的人是个例外，他们经常报告使用电子烟是为了戒烟/减少吸烟量。相反，大学生报告的使用原因与情感因素（如享受）有关。总体而言，报告为享受而使用电子烟的情况比为戒烟而使用更为常见；情感因素可能在电子烟的流行中起作用，在未来对电子烟使用者的评估中应予以考虑。
