About

The specific aims of this study are to determine the efficacy and cost-effectiveness of a weight loss program compared with usual care (control) treatment on 6-month changes in body weight, body fat, and serum hormones in breast cancer survivors.

Full description

Proposed is a three-arm randomized controlled trial of 6-months of weight loss counseling (i.e., dietary-induced caloric restriction and physical activity) on clinically meaningful endpoints in 100 breast cancer survivors . The three arms will be: 1. In-person counseling, 2. Telephone-based counseling, 3. Usual care. Women will be randomized into one of 3 study arms using a random permuted block design. Research staff collecting body composition data, as well as reviewing forms and entering data, will be blinded to the participant's study group.

---

100 participants in 3 patient groups

In-Person Counseling

Active Comparator group

Description:

Participants randomized to in-person counseling will meet via in-person or via telephone (but at least 3 of the 11 sessions must be in person) weekly for month 1, then every other week for months 2, and 3, and then monthly for months 4-6 at Yale University. The meetings will last 30 minutes. Participants will turn in their diet and exercise logs and also be weighed. A lesson will then be discussed (see above for content).

Treatment:

Behavioral: Weight Loss Counseling- In-Person

Telephone-based Counseling

Active Comparator group

Description:

The exact same information, content, schedule, and 30 minute sessions will be provided to telephone-based participants as offered to participants who receive in-person counseling. Participants will be taught diet, exercise and behavior change strategies via the telephone (weekly calls for month 1, every other week for months 2-3, and monthly for months 4-6). All lessons and diet and physical activity logs will be mailed to them at the beginning of the program. Participants will record their daily diet and exercise in the logs. Every four weeks, participants will return, via stamped, addressed envelopes, the logs to the study office.

Treatment:

Behavioral: Weight Loss Counseling- Phone

Usual Care

No Intervention group

Description:

Immediately after randomization, participants in the Usual Care Group will be provided written information that emphasizes the importance of a healthy lifestyle. Usual care participants will be encouraged to follow the American Cancer Society (ACS) nutrition and physical activity guidelines. Upon completion of the study (at 6 months), usual care participants will be offered all the educational material, as well as an in-person or telephone counseling session.
