In Ho Chi Minh City, Vietnam, recent studies found a rapid increase in overweight and obesity in adolescents. There is a need for effective health promotion interventions to support healthy diets and encourage a physically active lifestyle. This study will help fill an evidence gap on effective interventions to prevent excess weight gain in adolescents and generate new insights about peer-led education to promote healthy lifestyles.
We aim to assess the feasibility and acceptability of a combined peer-led and peer support intervention among junior high school students in Ho Chi Minh City. Additionally, the efficacy of the intervention on adolescents' dietary practices and time spent on physical activity will also be measured in this pilot study.
The Peer Education and Peer Support (PEPS) project is a pilot cluster randomized controlled trial with 2 intervention and 2 control schools. The intervention consists of 4 weekly education sessions of why and how to choose healthy food and drinks and how to be more physically active. Additionally, the intervention includes a school-based and online support system to help maintain student engagement during the intervention. We will use in-depth interviews with students, peer leaders, teachers, and parents; focus group discussions with peer educators; and direct observation of the school environment and peer leaders' interactions with the students. Acceptability and feasibility of the intervention will be assessed. We will also quantitatively assess limited efficacy by measuring changes in student' physical activity levels and dietary behaviors.
We delivered the peer education intervention at the start of each school year over 3 months for all new grade 6 adolescents in the selected schools, followed by peer support and home engagement activities over 6 months until the end of the school year. There was a baseline assessment and 2 post-intervention assessments: the first immediately after the intervention to assess the short-term impact and the second at the end of the school year to assess the sustained impact on changes in adiposity, diet, and physical activity.
The findings of this study will be used to develop a larger-scale cluster randomized controlled trial to examine the impact of a multicomponent, school- and home-based health promotion intervention. The trial will use innovative peer education methods to reduce overweight and obesity and improve dietary choices and physical activity levels in Vietnamese adolescents.

在越南胡志明市，近期研究发现青少年超重和肥胖现象迅速增加。需要有效的健康促进干预措施来支持健康饮食并鼓励积极的生活方式。本研究将有助于填补关于预防青少年体重过度增加的有效干预措施方面的证据空白，并产生关于同伴主导教育以促进健康生活方式的新见解。
我们旨在评估在胡志明市初中生中开展同伴主导与同伴支持相结合干预措施的可行性和可接受性。此外，在这项试点研究中还将测量该干预措施对青少年饮食习惯和体育活动时间的效果。
同伴教育与同伴支持（PEPS）项目是一项试点整群随机对照试验，有2所干预学校和2所对照学校。干预措施包括为期4周的每周一次教育课程，内容是关于为何以及如何选择健康的食物和饮料，以及如何增加体育活动。此外，干预措施还包括一个校内和在线支持系统，以帮助在干预期间维持学生的参与度。我们将对学生、同伴领袖、教师和家长进行深入访谈；与同伴教育者进行焦点小组讨论；并直接观察学校环境以及同伴领袖与学生的互动。将评估干预措施的可接受性和可行性。我们还将通过测量学生体育活动水平和饮食行为的变化来定量评估有限的效果。
我们在每个学年开始时，为选定学校所有新入学的六年级青少年开展为期3个月的同伴教育干预，随后在接下来的6个月里开展同伴支持和家庭参与活动，直至学年结束。有一次基线评估和两次干预后评估：第一次在干预结束后立即进行，以评估短期影响，第二次在学年结束时进行，以评估对肥胖、饮食和体育活动变化的持续影响。
本研究的结果将用于开展一项更大规模的整群随机对照试验，以检验一项多成分、基于学校和家庭的健康促进干预措施的影响。该试验将采用创新的同伴教育方法来减少越南青少年的超重和肥胖现象，并改善他们的饮食选择和体育活动水平。
