Nondaily smokers represent a growing proportion of current smokers in the United States. However, little is known about which characteristics are important in distinguishing between nondaily smokers who are former daily smokers (converted nondaily) and nondaily smokers who never smoked daily (native nondaily). This study contrasts converted and native nondaily smokers on demographic, psychosocial, tobacco-related characteristics and quit intentions and behaviors in a tri-ethnic sample (Blacks, Whites, and Latinos) of smokers.
Smokers were recruited for a web-based survey using an online panel survey company. Participants were 1,201 nondaily smokers (904 converted nondaily smokers and 297 native nondaily smokers). A multivariable logistic regression was conducted to assess the associations between demographic, smoking-related, and psychosocial variables with converted versus native nondaily smoking.
Logistic regression indicated that number of years smoking, years as a nondaily smoker, number of days smoked in a month, smoking dependence, identity as a smoker, and number of smoking cessation methods used were correlates of being converted nondaily smokers versus native nondaily smokers.
Clinicians and researchers should consider characteristic variations in nondaily smokers when designing and implementing intervention efforts targeting this smoking population.
在美国，非每日吸烟者在当前吸烟者中所占比例日益增加。然而，对于区分曾经每日吸烟的非每日吸烟者（转变型非每日吸烟者）和从未每日吸烟的非每日吸烟者（原生型非每日吸烟者）的重要特征知之甚少。本研究在吸烟者的三族裔样本（黑人、白人和拉丁裔）中，对比了转变型和原生型非每日吸烟者在人口统计学、心理社会、烟草相关特征以及戒烟意愿和行为方面的差异。
通过在线面板调查公司招募吸烟者参与基于网络的调查。参与者为1201名非每日吸烟者（904名转变型非每日吸烟者和297名原生型非每日吸烟者）。进行多变量逻辑回归分析，以评估人口统计学、吸烟相关和心理社会变量与转变型非每日吸烟和原生型非每日吸烟之间的关联。
逻辑回归表明，吸烟年限、非每日吸烟年限、每月吸烟天数、吸烟依赖性、吸烟者身份以及使用的戒烟方法数量是区分转变型非每日吸烟者和原生型非每日吸烟者的相关因素。
临床医生和研究人员在针对这一吸烟人群设计和实施干预措施时，应考虑非每日吸烟者的特征差异。
