Breast Cancer Clinical Trial
Cancer, Obesity/Overweight and Insomnia Study
Summary
This is a randomized pilot study to better understand the relationships among insomnia, weight loss, and breast cancer. This study will assess the effectiveness of a sleep intervention prior to a web- and phone-based weight loss program.
Full Description
Participants are women with a diagnosis of early stage breast cancer (ESBC), a BMI ≥25, and insomnia. A total of 30 participants will be randomized to either cognitive behavioral therapy for insomnia and behavioral weight loss (CBT-I+BWL) or a sleep education program and behavioral weight loss (EDU+BWL). Measures will be collected at baseline, 8 weeks (after the CBT-I or EDU program) and at 3 and 6 months after starting BWL. The primary outcome will be % total weight loss. Additionally, eating behaviors, physical activity, and sleep parameters will be carefully assessed.
The sleep intervention phase of the study includes 6 sessions over 8 weeks (2 in-person, followed by 4 phone or videoconferencing sessions), and the BWL intervention includes 15 sessions over 6 months (1 in-person, 14 by phone or videoconference). Participants will be given physical activity trackers and will use a dietary app to record their food intake. There are 4 in-person assessment visits (baseline/randomization, 8-week follow up, 3-month follow up, 6-month follow up). These assessment visits are coordinated with in-person sleep and weight loss intervention visits. Some of the measures that will be recorded throughout the study include: height, weight, anthropometric measures (waist/hip measurements), sleep diaries, and self-report measures.
