Adolescence is a rapid life stage requiring special attention wherein personal autonomy is developed to govern independent lifestyles. Unhealthy lifestyles are integral to prevailing adolescent physical inactivity patterns. Understudied 16-18-year-olds were investigated to establish physical activity prevalences and influencing health-related lifestyle factors. Adolescents were recruited randomly across 2017-2019 from Farnborough College of Technology and North Kent College, UK. Demographic and health-related lifestyle information were gathered anonymously and analysed using SAS 9.4 software. Among the 414 adolescents included (48.3% male and 51.7% female), the mean (standard deviation (SD)) age was 16.9 (0.77). Approximately 15.2% smoked and 20.8% were overweight/obese. There were 54.8% perceiving themselves unfit and 33.3% spent >4 h/day on leisure-time screen-based activity. Around 80.4% failed to meet the recommended fruit/vegetable daily intake and 90.1% failed to satisfy UK National Physical Activity Guidelines, particularly females ( = 0.0202). Physical activity levels were significantly associated with gender, body mass index, smoking status, leisure sedentary screen-time, fruit/vegetable consumption and fitness perceptions. Those who were female, overweight/obese, non-smoking, having poor fitness perceptions, consuming low fruit/vegetables and engaging in excess screen-based sedentariness were the groups with lowest physical activity levels. Steering physical activity-oriented health interventions toward these at-risk groups in colleges may reduce the UK's burden of adolescent obesity.
青春期是一个快速发展的生命阶段，需要特别关注，在此期间，个人自主性得以发展，以管理独立的生活方式。不健康的生活方式是普遍存在的青少年缺乏身体活动模式的组成部分。本研究对 16-18 岁的青少年进行了研究，以确定他们的身体活动流行率以及影响健康相关生活方式的因素。2017-2019 年，英国法恩伯勒技术学院和北肯特学院随机招募了青少年。匿名收集人口统计学和与健康相关的生活方式信息，并使用 SAS 9.4 软件进行分析。在纳入的 414 名青少年中（48.3%为男性，51.7%为女性），平均（标准差（SD））年龄为 16.9（0.77）。约 15.2%的人吸烟，20.8%的人超重/肥胖。有 54.8%的人认为自己身体不健康，33.3%的人每天花超过 4 小时在休闲时间看屏幕。约 80.4%的人没有达到推荐的水果/蔬菜每日摄入量，90.1%的人没有达到英国国家身体活动指南，尤其是女性（ = 0.0202）。身体活动水平与性别、体重指数、吸烟状况、休闲久坐屏幕时间、水果/蔬菜摄入量和健康感知显著相关。女性、超重/肥胖、不吸烟、健康感知差、水果/蔬菜摄入量低、久坐屏幕时间长的青少年身体活动水平最低。在学院中针对这些高危人群开展以身体活动为导向的健康干预措施，可能会降低英国青少年肥胖的负担。
