Breast Cancer Survivorship, Obesity
Conditions
Brief summary
Proposed is a 6-month randomized controlled trial, in 200 overweight or obese Stage I-IIIC breast cancer survivors examining 6-month changes in: 1) body weight, 2) diet, 3) physical activity, and 4)quality of life in women randomized to receive the modified LEAN intervention compared to women randomized to wait-list control (i.e., the wait-list control will receive the modified LEAN intervention after completing the 6-month study).
Detailed description
The purpose of the study is to evaluate the effects of modifying the LEAN intervention (NCT02110641) to make it more cost effective by reducing or eliminating the counseling sessions. To guide the modification of the intervention one or more focus group sessions with former LEAN participants will be conducted. The purpose of these meetings will be to gain input on enhancing the LEAN book. The LEAN book will be central to the modified intervention, but the LEAN book will be modified based on feedback from the focus group(s) and experience gained from the LEAN study. The reading level of the LEAN book will also be assessed to ensure acceptability to those with a low literacy level. Once these changes have been finalized, the efficacy of the modified program will be tested using the methods described in the Brief Summary.
Interventions
BEHAVIORALLEAN book/videos
The intervention focuses on achieving long lasting lifestyle changes to achieve weight loss and maintenance. Women randomized to the weight loss program will receive the LEAN book, as well as a CD and flash drive with the LEAN videos (and internet link), a pedometer and the Log Book for recording their food intake and physical activity.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Body weight (kg) | 6 Months | A standard digital scale will be mailed to each participant along with the baseline packet to allow consistent measurement of weight by participants. Participants will weigh themselves. Body weight will be collected in kilograms (kg). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Body weight (kg) | Baseline | A standard digital scale will be used to measure participants at baseline. Body weight will be collected in kilograms (kg). |
| Quality of Life (QOL) | Baseline | QOL will be self-reported and collected at the baseline and 6-months. The Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaire will be administered to assess overall quality of life. The FACT-B measures physical, emotional, social, and functional well-being as well as quality of life issues specific to breast cancer survivors. The overall score will be used for assessment. |
| Dietary Intake | Baseline | The endpoint measures of diet change will be mean, group level changes in daily caloric intake, based on a 120-item food frequency questionnaire (FFQ) which was developed for the Women's Health Initiative Study and has been validated against 4-Day Food Records and 24-hour Dietary Recalls. The FFQ is used to generate the Healthy Eating Index score (HEI). The HEI will be used to assess dietary intake. |
| Physical Activity (Moderate) | Baseline | Women will complete a physical activity questionnaire to assess their past six months of physical activity.10 Hours/week spent in different types (recreational, household, and occupation) and intensities (light, moderate, and vigorous-intensity) of activity will be computed over the past six months. Total minutes per week will be calculated from this survey for moderate and vigorous activity. |
| Physical Activity (Vigorous) | Baseline | Women will complete a physical activity questionnaire to assess their past six months of physical activity.10 Hours/week spent in different types (recreational, household, and occupation) and intensities (light, moderate, and vigorous-intensity) of activity will be computed over the past six months. Total minutes per week will be calculated from this survey for moderate and vigorous activity. |
