Mobile Behavior Change Program for Weight Loss in Breast Cancer Survivors

Preliminary Examination of a Mobile Behavior Change Program for Weight Loss in Breast Cancer Survivors

The purpose of this study is to evaluate the preliminary efficacy of a Noom Breast Cancer Weight Loss Program on weight loss outcomes, quality of life, and physical activity. Also, to qualitatively determine acceptability of this novel program among breast cancer survivors with overweight or obesity.

This is a prospective, single-arm pilot study evaluating preliminary efficacy and acceptability of a Noom breast cancer survivor weight loss program. The intervention consists of a curriculum, provided through daily articles that users are encouraged to read; logging features for weight, meals, and physical activity; in-app groups; and a virtual coach, who will communicate with participants via in-app messaging. During the first week of the study, participants will be introduced to the program, the Noom app, and their coach. Coaches will use a secure dashboard to monitor patient progress, which is used to increase engagement and motivation. Participants are encouraged to log their weight, physical activity, and meals daily.
