Abstract

Background: Metabolic and bariatric surgery (MBS) is a safe and effective treatment for adolescents with severe obesity, yet no standardized lifestyle interventions exist to support sustained behavior change after MBS.

Objective: This pilot study assessed the feasibility and acceptability of TeenLyft, an online lifestyle support program for adolescents undergoing MBS, and explored preliminary clinical and safety outcomes to inform the design of a future randomized trial.

Methods: Adolescents aged 13 to 18 years were recruited from a tertiary care MBS center and enrolled in TeenLyft. The study was not powered or designed as a randomized controlled trial but rather as a pilot to guide future randomized controlled trial development. Feasibility domains included recruitment, retention, data completeness, intervention fidelity, and engagement, with predefined progression criteria of ≥80% enrollment, ≥70% retention, ≥70% data completeness, and ≥90% fidelity. Exploratory clinical and safety measures (weight, BMI, and cardiometabolic markers) were collected descriptively to confirm that participation was not associated with harm.

Results: Twenty-nine adolescents (mean age 15.9 years, SD 1.1; n=22, 75.9% female; n=13, 44.8% Hispanic; mean BMI 47.8, SD 7.3 kg/m²) were enrolled, representing 145% of the recruitment target (n=20), with 72.4% retention at 6 months. All feasibility progression criteria were met. Descriptive trends showed expected post-MBS reductions in weight and BMI and improvements in blood pressure and hemoglobin A_1c, with no adverse cardiometabolic effects observed.

Conclusions: TeenLyft demonstrated high feasibility, acceptability, and safety as an adjunct to adolescent MBS care. Findings support progression to a fully powered randomized trial to evaluate long-term effectiveness and sustainability.

接受代谢和减肥手术的青少年的在线生活方式支持：试点前瞻性队列研究。

背景：代谢和减肥手术（MBS）是一种安全有效的治疗青少年严重肥胖的方法，但目前还没有标准化的生活方式干预措施来支持MBS后持续的行为改变。目的：本初步研究评估了青少年MBS在线生活方式支持项目TeenLyft的可行性和可接受性，并探讨了初步的临床和安全性结果，为未来随机试验的设计提供信息。方法：从三级保健MBS中心招募13至18岁的青少年并加入TeenLyft。该研究不是作为随机对照试验进行的，而是作为指导未来随机对照试验发展的试点。可行性领域包括招募、保留、数据完整性、干预保真度和参与度，预定义的进展标准为≥80%的入组、≥70%的保留、≥70%的数据完整性和≥90%的保真度。描述性地收集探索性临床和安全措施（体重、BMI和心脏代谢指标），以确认参与与危害无关。结果：纳入29名青少年（平均年龄15.9岁，SD 1.1; n=22，女性75.9%;n=13，西班牙裔44.8%；平均BMI 47.8, SD 7.3 kg/m2），占招募目标的145% (n=20)， 6个月时保留率为72.4%。所有可行性进展标准均得到满足。描述性趋势显示预期的mbs后体重和BMI降低，血压和血红蛋白A1c改善，没有观察到不良的心脏代谢影响。结论：TeenLyft作为青少年MBS治疗的辅助手段具有很高的可行性、可接受性和安全性。研究结果支持进行一项全动力随机试验，以评估长期有效性和可持续性。
