Feasibility of a lifestyle intervention for overweight/obese endometrial and breast cancer survivors using an interactive mobile application.

OBJECTIVE

The study aimed to assess a one-month lifestyle intervention delivered via a web- and mobile-based weight-loss application (app) (LoseIt!) using a healthcare-provider interface.

METHODS

Early-stage overweight/obese (body mass index [BMI]≥25kg/m(2)) cancer survivors (CS) diagnosed in the past three years, and without recurrent disease were enrolled and received exercise and nutrition counseling using the LoseIt! app. Entry and exit quality of life (FACT-G) and Weight Efficacy Lifestyle Questionnaire (WEL) measuring self-efficacy were measured along with anthropometrics, daily food intake, and physical activity (PA) using the app.

RESULTS

Mean participant age was 58.4±10.3years (n=50). Significant reductions (p<0.0006) in anthropometrics were noted between pre- and post-intervention weight (105.0±21.8kg versus 98.6±22.5kg); BMI (34.9±8.7kg/m(2) versus 33.9±8.4kg/m(2)); and waist circumference (108.1±14.9cm versus 103.7±15.1cm). A significant improvement in pre- and post-intervention total WEL score was noted (99.38±41.8 versus 120.19±47.1, p=0.043). No significant differences were noted in FACT-G, macronutrient consumption, and PA patterns.

CONCLUSIONS

These results indicate that a lifestyle intervention delivered via a web- and mobile-based weight-loss app is a feasible option by which to elicit short-term reductions in weight. Though these results parallel the recent survivors of uterine cancer empowered by exercise and healthy diet (SUCCEED) trial, it is notable that they were achieved without encumbering significant cost and barrier-access issues (i.e. time, transportation, weather, parking, etc.).
