The problem
Intervention: TeenLyft, an online lifestyle support program delivered as an adjunct to bariatric surgery care
Who it was tested with: Adolescents aged 13-18 years with severe obesity undergoing metabolic and bariatric surgery at a tertiary care center (n=29, mean age 15.9 years, 76% female, 45% Hispanic).
The same group is measured before the intervention and again afterwards, with a baseline and an endline and sometimes a midline. Change is visible, but other causes cannot be ruled out.
"The study was not powered or designed as a randomized controlled trial but rather as a pilot to guide future randomized controlled trial development." The feasibility assessment confirms the program can be delivered and is acceptable to adolescents, but the pre-post design without a control group means clinical effectiveness remains inconclusive.
This pilot study lacks a comparison group, so improvements in weight, BMI, and metabolic markers cannot be attributed to the TeenLyft intervention versus normal post-surgery outcomes. The study was explicitly not powered to evaluate clinical effectiveness.
