目的探讨继父母和亲生父母吸烟对青少年吸烟的预测作用。设计5年队列研究。英国伦敦南部有36所学校。参加青少年健康和行为研究（习惯）的650名学生报告生活在继家庭，他们从11-12岁到15-16岁每年接受一次评估。学生报告了他们的吸烟状况，这是可替宁验证，以及他们的父母是否吸烟，如果他们与继父母住在一起，该继父母是否吸烟。分析还控制了性别、种族和贫困的因素。在11-12岁时报告其继父或继母吸烟的学生在11-16岁的任何时间点报告当前吸烟的可能性明显高于那些既没有亲生父母也没有继父或继母吸烟的学生[比值比（OR） 2.72, 95%置信区间(CI) = 1.36-5.47]，父母一方和继父或继母都吸烟的学生也是如此（OR 2.23, 95% CI = 1.46-3.41）。虽然该子样本中学生吸烟与亲生父母吸烟之间的关联没有达到统计学意义（OR 1.39, 95% CI = 0.88-2.19），但这些学生吸烟的可能性并不比那些只有继父或继母吸烟的学生多或少。结论非亲生父母吸烟的影响至少与亲生父母吸烟的影响相同。这证实了社会影响对开始吸烟的重要性，并建议在与父母一起预防吸烟的努力中应该让吸烟的继父母参与进来，也许应该特别注意吸烟的继父母。
Aim To examine the extent to which smoking by step-parents and biological parents predicts adolescent smoking. Dsign Five-year cohort study. Setting Thirty-six schools in South London, England. Participants A subset of 650 students participating in the Health and Behaviour In Teenagers Study (HABITS), who reported living in step-families, were assessed annually from age 11-12 to age 15-16 years. Measurements Students reported their smoking status, which was cotinine-verified, as well as whether their parents smoked and, if they lived with a step-parent, whether that step-parent smoked. Analyses also controlled for gender, ethnicity and deprivation. Findings Students who reported that just their step-parent smoked at age 11-12 were significantly more likely to report current smoking at any time-point from age 11-16 than those who reported having neither biological parents nor a step-parent who smoked [odds ratio (OR) 2.72, 95% confidence interval (CI) = 1.36-5.47], as were those with both a parent and a step-parent who smoked (OR 2.23, 95% CI = 1.46-3.41). While the association between smoking in students and smoking in biological parents in this subsample did not reach statistical significance (OR 1.39, 95% CI = 0.88-2.19), these students were no more or less likely to smoke than those with just a step-parent who smoked. Conclusion Smoking by a non-biological parent appears at least as influential as smoking by biological parents. This confirms the importance of social influence on smoking initiation and suggests that attempts to work with parents in smoking prevention should involve, and perhaps pay particular attention to, step-parents who smoke.
