Web-based Lifestyle Program, mHealth and EMA Intervention, to Improve Weight Loss in Rural Stage I-III Postmenopausal Breast and Endometrial Cancer Survivors, HERO-C Trial

This clinical trial identifies the needs and preferences of rural stage I-III postmenopausal breast and endometrial cancer survivors and evaluates the impact of an adaptive, online program, mobile (m)Health + ecological momentary assessment (EMA) intervention, on lifestyle modification and their weight loss efforts. Obesity, a condition marked by an abnormally high, unhealthy amount of body fat, is associated with lower physical and psychological well-being, higher risk of recurrence, and higher cancer-specific and all-cause mortality (number of deaths). Lifestyle factors, such as low physical activity and unhealthy diet, are the main contributors to obesity that are modifiable. Lifestyle weight loss programs focusing on modifiable factors can improve cancer-specific survival and many aspects of health, but access to these programs can be challenging in rural settings. A remote lifestyle program, adapted to individual goals and needs, may help promote healthy behaviors, improve cancer outcomes, and reduce disease burden in stage I-III postmenopausal breast and endometrial cancer survivors.
