Profile of e-cigarette use and its relationship with cigarette quit attempts and abstinence in Kansas adults
Menée aux Etats-Unis à partir d'une enquête téléphonique réalisée sur la période 2012-2013 auprès de 9 656 adultes, cette étude analyse la relation entre l'utilisation de la cigarette électronique et l'abstinence tabagique ou les tentatives d'arrêter de fumer
Objective : Describe electronic cigarette use in Kansas adults and its relationship with cigarette cessation. Methods : The Kansas Adult Tobacco Survey (ATS) is a 2012–2013 phone survey of non-institutionalized Kansas adults (N = 9,656). The ATS was analyzed to create a profile of cigarette and e-cigarette users, and demonstrate associations between e-cigarette use and cigarette cessation attempts and cigarette abstinence. Results : In 2013, 45% of adult cigarette smokers had tried e-cigarettes and 14% had used e-cigarettes in the past month. The prevalence of current cigarette smoking was 76.5% among past-month e-cigarette users. Adults who only use e-cigarettes are younger and more affluent than adults who only smoke cigarettes. The prevalence of past-month e-cigarette use among smokers who made a quit attempt in the past year is more than double that of smokers who did not. E-cigarette use was negatively associated with past-month (aPOR = 0.21, 95% CI: 0.11-0.38) and past-year cigarette abstinence (aPOR = 0.14, 95% CI: 0.10-0.22). Conclusions : E-cigarette use is common among cigarette smokers. E-cigarette use is more common among smokers who made a recent quit attempt and many smokers report using smokeless tobacco or e-cigarettes to help quit. Recent cigarette abstinence, however, is negatively associated with e-cigarette use.
