The main aim was to examine the effects of a school-based intervention on multiple health behaviors in adolescents, such as 24-hour movement behaviors (i.e., physical activity, sedentary time, and sleep duration), diet, and substance consumption (i.e., alcohol and tobacco). Another aim was to examine intragender differences in the effectiveness of the programme.
A quasi-experimental design was carried out in two secondary schools throughout one academic year. A final sample of 210 students participated: 105 in the control (Mage = 13.07 ± 0.63) and 105 in the experimental school (Mage = 13.05 ± 0.59). A multicomponent school-based intervention was conducted by teachers in the experimental school via curricular (i.e., tutorial action plan, interdisciplinary project, and school break) and extracurricular (i.e., family involvement, institutional and noncurricular activities, and dissemination of health information and events) actions to promote adolescents' healthy lifestyles. Physical activity and sedentary time were measured by accelerometers, and the rest of health behaviors by using self-reported scales.
Experimental school students showed a significant improvement in meeting specific and general combinations of 24-hour movement guidelines, sedentary screen time levels, nap duration, (un)healthy diet scores, breakfast intake, and soft drink consumption compared to both control school students and their baseline values (p >.05). Active commuting and substance consumption rates only showed a significant improvement compared to control school students (p >.05). Although the intervention programme was effective in improving health-related behaviors in both genders, a large effect size was observed in boys.
Conducting multiple health behavior interventions becomes essential to improve adolescents' healthy lifestyles.
本研究旨在考察一项基于学校的干预措施对青少年多种健康行为的影响，如 24 小时运动行为（即体力活动、久坐时间和睡眠时间）、饮食和物质消费（即酒精和烟草）。另一个目的是检验该方案在性别内的有效性差异。
在一学年内，在两所中学进行了一项准实验设计。最终有 210 名学生参与了研究：对照组 105 名（平均年龄 13.07 ± 0.63），实验组 105 名（平均年龄 13.05 ± 0.59）。实验组的教师通过课程（即辅导行动计划、跨学科项目和课间休息）和课外活动（即家庭参与、机构和非课程活动以及健康信息和活动的传播）来实施多方面的基于学校的干预措施，以促进青少年的健康生活方式。通过加速度计测量体力活动和久坐时间，通过自我报告量表测量其他健康行为。
与对照组学生和自身基线相比，实验组学生在满足特定和一般 24 小时运动指南、久坐屏幕时间水平、午睡时间、（健康/不健康）饮食评分、早餐摄入和软饮料消费方面均有显著改善（p>.05）。与对照组相比，仅主动通勤和物质消费率有显著改善（p>.05）。尽管干预方案在改善两性的健康相关行为方面均有效，但在男孩中观察到较大的效果量。
开展多种健康行为干预措施对于改善青少年的健康生活方式至关重要。
