青少年尼古丁依赖（NDIT）研究是一项前瞻性队列研究，1999-2000年在加拿大蒙特利尔的10所高中的便利样本中招募了1294名7年级学生。其主要目的是研究吸烟和尼古丁依赖新手的自然过程和决定因素。数据的主要来源是在学校课堂上进行的自报问卷调查，从7年级到11年级（1999-2005年）每3个月一次，在高中教育期间共进行了20个调查周期。调查问卷也是在2007-08年和2011-12年高中毕业后完成的（调查周期分别为21和22），参与者的平均年龄分别为20岁和24岁。除了其主要目标外，NDIT还嵌入了关于肥胖、血压、体育活动、团队运动、久坐行为、饮食、遗传学、酒精使用、非法药物使用、二手烟、赌博、睡眠和心理健康的研究。迄今为止的结果在58篇出版物，20篇正在编写的手稿，13篇硕士和博士论文和111篇会议报告中进行了描述。NDIT数据开放给大学指定或附属的研究人员以及硕士、博士和博士后学生，通过他们的主要导师（ext-link-type=“uri”xlink：href=”http://www.nditstudy.ca“xlink：type=“simple”>www.nditstudy.ca）。
The Nicotine Dependence in Teens (NDIT) study is a prospective cohort investigation of 1294 students recruited in 1999-2000 from all grade 7 classes in a convenience sample of 10 high schools in Montreal, Canada. Its primary objectives were to study the natural course and determinants of cigarette smoking and nicotine dependence in novice smokers. The main source of data was self-report questionnaires administered in class at school every 3 months from grade 7 to grade 11 (1999-2005), for a total of 20 survey cycles during high school education. Questionnaires were also completed after graduation from high school in 2007-08 and 2011-12 (survey cycles 21 and 22, respectively) when participants were aged 20 and 24 years on average, respectively. In addition to its primary objectives, NDIT has embedded studies on obesity, blood pressure, physical activity, team sports, sedentary behaviour, diet, genetics, alcohol use, use of illicit drugs, second-hand smoke, gambling, sleep and mental health. Results to date are described in 58 publications, 20 manuscripts in preparation, 13 MSc and PhD theses and 111 conference presentations. Access to NDIT data is open to university-appointed or affiliated investigators and to masters, doctoral and postdoctoral students, through their primary supervisor ( ext-link-type="uri" xlink:href="http://www.nditstudy.ca" xlink:type="simple">www.nditstudy.ca).
