To explore the association among the number of sources of secondhand tobacco smoke (SHS) exposure, nicotine dependence (ND), and smoking cessation.
A secondary analysis of cross-sectional data. Responses for the main study were obtained in 2001 from a controlled trial of the Quit and Win Tobacco Free Contest in Kentucky.
822 current smokers.
Demographic variables (age, gender, educational status, income, and ethnicity) the number of sources of SHS exposure, smoking frequency, length of abstinence from smoking, age of smoking initiation, smoking cessation attempts, intentions to quit smoking, and ND.
The number of sources of SHS exposure was associated with higher ND and smoking frequency, and related to low intentions and attempts to quit smoking. The number of sources of SHS exposure contributed to 11% of the variance in the final ND model, after accounting for control and potential mediating variables.
The number of sources of SHS exposure may be an important factor influencing ND and intentions and attempts to quit smoking. Further studies are needed to explore the association between SHS exposure and ND among smokers to guide treatment and policy development.
探讨二手烟暴露源数量、尼古丁依赖及戒烟之间的关联。
横断面数据的二次分析。主要研究的回复于2001年从肯塔基州戒烟与无烟竞赛的一项对照试验中获取。
822名当前吸烟者。
人口统计学变量（年龄、性别、教育程度、收入及种族）、二手烟暴露源数量、吸烟频率、戒烟时长、开始吸烟年龄、戒烟尝试、戒烟意愿及尼古丁依赖。
二手烟暴露源数量与较高的尼古丁依赖及吸烟频率相关，且与较低的戒烟意愿及尝试有关。在考虑了对照和潜在中介变量后，二手烟暴露源数量在最终的尼古丁依赖模型中解释了11%的方差。
二手烟暴露源数量可能是影响尼古丁依赖、戒烟意愿及戒烟尝试的一个重要因素。需要进一步研究来探讨吸烟者中二手烟暴露与尼古丁依赖之间的关联，以指导治疗和政策制定。
