As of October 2015, evidence needed to make a recommendation about the use of electronic nicotine delivery systems (ENDS) for smoking cessation was limited. We used the 2014 Arkansas Behavioral Risk Factor Surveillance System with additional state-specific questions to determine the prevalence of ENDS use, the impact of ENDS use on smoking cessation, and beliefs about ENDS use in Arkansas. Our objectives were to determine if (1) ENDS use was associated with lower odds of quitting smoking, (2) ENDS users believed that ENDS use was not harmful to their health, and (3) ENDS users believed that switching to ENDS reduced their tobacco-related health risks.
We conducted a cross-sectional study of 4465 respondents to the Arkansas Behavioral Risk Factor Surveillance System and used weighted analyses to account for the complex survey design. We used a subset of records formed by (1) formers smokers who quitted smoking in the last 5 years and (2) current smokers to assess the odds of quitting.
In 2014, 6.1% (95% confidence interval [CI], 5.0%-7.4%) of Arkansas adults were currently using ENDS. Of the 1083 participants who were current smokers or had quit smoking within the past 5 years, 515 (54.1%) had used ENDS. Of the 515 ENDS users, 404 (80.3%) had continued smoking. ENDS use was significantly associated with reduced odds of quitting smoking (weighted odds ratio = 0.53; 95% CI, 0.34-0.83). Although 2437 of 3808 participants (62.5%) believed that it was harmful for nonsmokers to start using ENDS and 1793 of 3658 participants (47.0%) believed that switching to ENDS did not reduce tobacco-related health risks, only 80 of 165 (41.3%) and 50 of 168 (33.9%) ENDS users shared these same respective beliefs.
Most smokers who indicated smoking in the past 5 years and who tried ENDS did not stop smoking. ENDS use was inversely associated with smoking cessation. Tobacco cessation programs should tell cigarette smokers that ENDS use may not help them quit smoking.
截至2015年10月，关于使用电子尼古丁传送系统（ENDS）辅助戒烟的推荐所需证据有限。我们利用2014年阿肯色州行为风险因素监测系统及附加的州特定问题，来确定ENDS的使用 prevalence、ENDS使用对戒烟的影响以及阿肯色州民众对ENDS使用的看法。我们的目标是确定：（1）ENDS使用是否与较低的戒烟几率相关；（2）ENDS使用者是否认为ENDS使用对其健康无害；（3）ENDS使用者是否认为改用ENDS可降低其烟草相关健康风险。
我们对阿肯色州行为风险因素监测系统的4465名受访者进行了横断面研究，并使用加权分析来考虑复杂的调查设计。我们使用由（1）过去5年内戒烟的 former smokers 和（2）当前吸烟者组成的记录子集来评估戒烟几率。
2014年，6.1%（95%置信区间[CI]，5.0%-7.4%）的阿肯色州成年人当前正在使用ENDS。在1083名当前吸烟者或过去5年内戒烟的参与者中，515人（54.1%）使用过ENDS。在515名ENDS使用者中，404人（80.3%）继续吸烟。ENDS使用与较低的戒烟几率显著相关（加权优势比=0.53；95%CI，0.34-0.83）。尽管3808名参与者中的2437人（62.5%）认为非吸烟者开始使用ENDS有害，3658名参与者中的1793人（47.0%）认为改用ENDS不会降低烟草相关健康风险，但在165名ENDS使用者中只有80人（41.3%）和168名ENDS使用者中的50人（33.9%）分别持有这些相同看法。
大多数在过去5年内表示吸烟且尝试过ENDS的吸烟者并未戒烟。ENDS使用与戒烟呈负相关。戒烟项目应告知吸烟者，使用ENDS可能无助于他们戒烟。
