Its primary objectives were to study the natural course and determinants of cigarette smoking and nic otine dependence in youth\, although the project also embeds studies on ob esity\, blood pressure\, physical activity\, team sports\, exergaming\, se dentary behaviour\, diet\, genetics\, alcohol use\, cannabis use\, use of e-cigarettes\, use of illicit drugs\, exposure to second-hand smoke\, gamb ling\, sleep and mental health. The main source of data was self-report qu estionnaires administered in class at school every 3 months from grade 7 t o grade 11 (1999–2005)\, for a total of 20 cycles during high school. Ques tionnaires were also completed after graduation from high school in 2007–0 8\, 2011–12\, and 2017-20 (cycles 21\, 22 and 23\, respectively) when part icipants were age 20\, 24 and 31 years on average\, respectively. Cycle 24 \, which collected data on COVID-19 was undertaken from December 2020 to J une 2021. Cycle 25 started in May 2022 and concluded in March 2023. Cycle 26 is ongoing. Data collection also comprised anthropometric measurements\ , DNA sampling\, parental questionnaires\, school environmental scans\, lu ng function\, handgrip strength\, as well as a pilot study involving child ren of NDIT study participants who smoke or vape cannabis to assess their lung function and to determine whether second- or thirdhand exposure to ca nnabis results in cannabis metabolites in their urine.\n\nLearning Objecti ves\n\nAt the end of this talk\, attendees will be able to:\n\n\n Understan d the design and scope of the NDIT study: Participants will be able to des cribe the structure\, duration\, and methodology of the 25-year longitudin al NDIT study\, including data collection methods and key participant demo graphics.\n Identify several key findings related to nicotine dependence an d other adolescent health behaviours: Attendees will gain insight into maj or outcomes of the study\, including determinants and trajectories of ciga rette smoking\, nicotine dependence\, and associated behaviours such as va ping\, cannabis use\, and physical activity.\n Evaluate the public health i mplications of long-term adolescent health research: Participants will cri tically assess how findings from longitudinal research like the NDIT study inform public health policy\, particularly in youth prevention strategies related to substance use and chronic disease risk factors.\n\n\nSpeaker B io\n\nDr. Jennifer O'Loughlin is a distinguished researcher in the field o f public health in Canada.
