Using an iPhone app to help adolescents and young adults lose weight after stem cell transplant

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This trial evaluates the effectiveness of a smartphone application combined with telephone coaching to promote weight loss in adolescents and young adults who are overweight or obese following hematopoietic stem cell transplantation. Participants will receive an iPhone with the W8Loss2Go app, a body scale, and a digital food scale to track their weight and food intake daily. They will interact with coaches through text messages and weekly phone calls for support and progress discussions, along with telemedicine interviews to address barriers to weight management. The study aims to assess not only weight outcomes but also changes in metabolic parameters, physical activity, and adherence to the intervention.
