To determine associations between younger youths' susceptibility to smoking and four household variables related to tobacco socialization: parental and sibling smoking, restrictions on smoking in the home and exposure to smoking in vehicles.
A secondary analysis of the 2004/05 Canadian Youth Smoking Survey used logistic regression to investigate the relationships between youth susceptibility to smoking, gender, and four household variables related to tobacco socialization. Susceptibility to smoking was operationalized by three levels of smoking experience and intention: non-susceptible non-smoker, susceptible non-smoker and experimenter/smoker. The national survey included 29 243 grade 5 to 9 students from randomly sampled public and private schools in ten provinces.
For non-smokers, the odds of being susceptible to smoking increased with having a sibling who smokes, a lack of a total household smoking ban and riding in a vehicle with a smoker in the previous week, when adjusting for all other variables in the model. These variables also increased the odds of being an experimenter/smoker versus a susceptible non-smoker. Parent smoking status was not significant in these models.
Denormalization messages, through enforced home and vehicle smoking bans, appear to support youth in maintaining a resolve to not smoke, regardless of parental smoking status.
确定青少年吸烟易感性与四个与烟草社会化相关的家庭变量之间的关联，这四个变量分别是：父母及兄弟姐妹吸烟情况、家中吸烟限制以及在车内接触吸烟情况。
对2004/05年加拿大青少年吸烟调查进行二次分析，采用逻辑回归研究青少年吸烟易感性、性别与四个与烟草社会化相关的家庭变量之间的关系。吸烟易感性通过三个吸烟经历和意向水平来衡量：不易感非吸烟者、易感非吸烟者和尝试吸烟者/吸烟者。全国性调查包括来自十个省份随机抽取的公立和私立学校的29243名五至九年级学生。
对于非吸烟者，在对模型中的所有其他变量进行调整后，有吸烟的兄弟姐妹、家中没有全面禁烟以及前一周在有吸烟者的车内乘车，会增加吸烟易感性的几率。这些变量也增加了成为尝试吸烟者/吸烟者而非易感非吸烟者的几率。在这些模型中，父母的吸烟状况并不显著。
通过在家庭和车内实施禁烟措施来传递去规范化信息，似乎有助于青少年坚定不吸烟的决心，无论父母的吸烟状况如何。
