Adolescents engage in multiple health risk behaviours that put them at risk of future chronic disease. By the time students graduate from secondary school, they may be engaging in behaviours that set them on a particular health trajectory. It is important to monitor the co-occurrence of health risk behaviours of cohorts of grade 12 students over time to highlight important areas for intervention. The purpose of this study was to examine trends in health and risk behaviours over six waves among subsequent cohorts of grade twelve students from Ontario, Canada. A total of 44,740 grade 12 students participated in the COMPASS study across the six waves (2013/14 to 2018/19), and self-reported movement (physical activity, screen time, sleep), dietary (fruit and vegetables, breakfast), and substance use (smoking, vaping, binge drinking, and cannabis use) behaviours. Over 91.0% of students reported engaging in three or more health risk behaviours, with increases in the number of students reporting inadequate sleep, not eating breakfast on every school day, and vaping over time. Although modest, the wave 6 cohort reported slightly more risk behaviours compared with the wave 1 cohort, highlighting the importance of multidimensional health promotion strategies across multiple settings.
青少年从事多种健康风险行为，使他们面临未来慢性病的风险。当学生从中学毕业时，他们可能正在从事一些行为，使他们走上特定的健康轨迹。重要的是要随着时间的推移监测 12 年级学生群体健康风险行为的同时发生情况，以突出干预的重要领域。本研究的目的是检查加拿大安大略省随后几批 12 年级学生在六个波次中健康和风险行为的趋势。共有 44740 名 12 年级学生参加了跨越六个波次（2013/14 至 2018/19 年）的 COMPASS 研究，报告了运动（身体活动、屏幕时间、睡眠）、饮食（水果和蔬菜、早餐）和物质使用（吸烟、蒸气、狂饮和大麻使用）行为。超过 91.0%的学生报告从事三种或更多种健康风险行为，随着时间的推移，报告睡眠不足、每天在学校不吃早餐和蒸气的学生人数增加。尽管幅度不大，但与第 1 波次相比，第 6 波次的学生报告的风险行为略多，这突出了在多个环境中采用多维健康促进策略的重要性。
