Research has yet to examine how physical activity, body mass index (BMI) and concerns about weight among youth populations are associated with susceptibility to smoking among never smokers. The Physical Activity Module of the School Health Action, Planning and Evaluation System (SHAPES) was completed by 25,060 students in grades 9 to 12 within 76 secondary schools in Ontario (Canada) to examine how being overweight, weight concerns, and physical activity are associated with susceptibility to smoking in a large sample of youth. Among the 14,795 students who were never smokers, 3,809 (25.8%) were classified as susceptible to future smoking and 10,986 (74.2%) were classified as non-susceptible to future smoking. Smoking susceptibility was negatively associated with being highly active or at risk of overweight and positively associated with perceptions of being slightly overweight or slightly underweight. Students who report 1 or more hours of screen or phone time per day were also more likely to be susceptible. This is the first study to identify that susceptibility to future smoking among never smokers is associated with physical activity, overweight and concerns about weight. This is valuable new insight for tailoring and targeting future school-based tobacco control and/or physical activity programming to youth populations.
关于青少年群体的身体活动、体重指数（BMI）以及对体重的担忧如何与从不吸烟者的吸烟易感性相关联，目前尚无研究。加拿大安大略省76所中学的25,060名9至12年级学生完成了学校健康行动、规划与评估系统（SHAPES）的身体活动模块，以研究在大量青少年样本中，超重、对体重的担忧和身体活动如何与吸烟易感性相关联。在14,795名从不吸烟者中，3,809人（25.8%）被归类为未来吸烟易感人群，10,986人（74.2%）被归类为未来吸烟不易感人群。吸烟易感性与高活动水平或超重风险呈负相关，与轻微超重或轻微体重不足的认知呈正相关。每天报告有1小时或更多屏幕或手机使用时间的学生也更有可能易感。这是第一项确定从不吸烟者未来吸烟易感性与身体活动、超重和对体重的担忧相关联的研究。这为针对青少年群体定制和开展未来基于学校的烟草控制和/或身体活动项目提供了宝贵的新见解。
