The prevalence of obesity among Chinese adolescents is rising rapidly, and theoretically informed, scalable weight management interventions are needed. We developed and evaluated the feasibility and preliminary effects of an mHealth nutrition education and mindful snacking intervention for weight loss and improved dietary practices among Chinese adolescents with overweight. We examined whether including implementation intention formation (using if-then plans) improved outcomes. With user consultation, we created a 3-week mindful eating intervention delivered as 10 videos to user smartphones. Participants (n = 55) were randomly assigned to mindful eating or mindful eating + planning. Forty-six (83.6%) participants (age = 16.35 ± 0.48 years; body mass index [BMI] = 25.79 ± 2.05 kg/m ) completed the intervention. Both groups exhibited significant pre- to post-intervention weight loss (M = 1.42 and 1.79 kg, respectively); decreases in snacking frequencies, emotional eating, external eating, and trait craving; and significant increases in mindful eating and eating self-efficacy. No significant intervention group differences were observed. User experience data (n = 16) indicated acceptability and meaningful behavior change. Findings suggest that a smartphone-delivered mindfulness-based intervention for Chinese adolescents living with overweight is feasible and efficacious.
中国青少年肥胖的患病率正在迅速上升，因此需要理论指导、可扩展的体重管理干预措施。我们开发并评估了一种基于移动医疗的营养教育和正念零食干预措施的可行性和初步效果，该干预措施旨在帮助超重的中国青少年减轻体重和改善饮食行为。我们研究了包含实施意图形成（使用如果-那么计划）是否能改善结果。在用户咨询的基础上，我们创建了一个为期 3 周的正念饮食干预措施，以 10 个视频的形式发送到用户的智能手机上。参与者（n=55）被随机分配到正念饮食组或正念饮食+计划组。46 名（83.6%）参与者（年龄=16.35±0.48 岁；BMI=25.79±2.05 kg/m ）完成了干预。两组均表现出显著的干预前至后体重减轻（分别为 1.42 和 1.79 公斤）；零食频率、情绪性进食、外部进食和特质渴望的减少；以及正念进食和进食自我效能感的显著增加。没有观察到干预组之间的显著差异。16 名用户体验数据（n=16）表明了可接受性和有意义的行为改变。研究结果表明，针对超重中国青少年的基于智能手机的正念干预措施是可行且有效的。
