Several studies in adults demonstrated a positive relationship between the number of cigarettes smoked and the urinary cotinine. The aim of this work was to analyze the passive and active smoking exposure of 333 sixteen-year-old students, demonstrated by their urinary cotinine, in comparison with the smoking habits of all the cohabitants. This last information was obtained from a questionnaire and urinary cotinine in mothers. The second purpose of this work was to observe whether the smoking habits of parents can promote the voluntary active exposure to tobacco smoke in children. The considered students represent a particular group of people (16 years old) having a life-style still strictly bound to the smoking habit of parents. In fact, the nonactive smokers show urinary cotinine levels described by the following means: 28.81, 39.35, 39.62, and 57.67 ng/mL. This finding demonstrates a trend of exposure from no exposure to a maximum level of passive exposure. Similar results can be observed by considering the urinary cotinine of mothers. Finally, the active smoking habit potentially acquired by the adolescents seems to be induced also by emulation of the smoking habits of fathers. This possibility is demonstrated by a light positive and statistically significative correlation with the number of cigarettes actively smoked and, consequently, with urinary cotinine.
多项针对成年人的研究表明，吸烟数量与尿中可替宁之间存在正相关关系。这项工作的目的是，通过333名16岁学生的尿中可替宁水平，分析他们被动和主动吸烟的暴露情况，并与所有同居者的吸烟习惯进行比较。后一项信息是通过问卷调查以及检测母亲的尿中可替宁获得的。这项工作的第二个目的是观察父母的吸烟习惯是否会促使孩子主动自愿接触烟草烟雾。所研究的学生代表了一类特殊人群（16岁），他们的生活方式仍与父母的吸烟习惯紧密相关。事实上，非吸烟者的尿中可替宁水平如下：28.81、39.35、39.62和57.67 ng/mL。这一发现显示出从无暴露到被动暴露最高水平的一种暴露趋势。考虑母亲的尿中可替宁水平也能观察到类似结果。最后，青少年潜在养成的主动吸烟习惯似乎也是受到对父亲吸烟习惯的模仿影响。主动吸烟数量与尿中可替宁之间存在轻度正相关且具有统计学意义，从而证明了这种可能性。
