Conditions breast cancer, weight loss
Treatment weight loss counseling
Phase phase 3
Sponsor Yale University
Start date November 2013
End date November 2016
Trial size 100 participants
Trial identifier NCT02110641, 1012007780_1


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, serum hormones, and breast tissue markers associated with prognosis in breast cancer survivors.

Study Design

Allocation randomized
Intervention model parallel assignment
Masking single blind (outcomes assessor)
Primary purpose treatment
(Active Comparator)
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.
weight loss counseling
The intervention will be based on the Diabetes Prevention Program weight loss program, which uses a combination of reduced caloric intake, increased physical activity, and behavior therapy. The content of the weight loss program will be similar for the in-person and telephone interventions, but the approach will vary (i.e., in-person vs. telephone counseling). The weight loss intervention will be conducted by a Registered Dietitian, who has training in exercise physiology and behavior modification.
(No Intervention)
At 6-months the participants in the Wait List group may choose to participate in the 11 sessions either in-person or via telephone or a combination of the two modes of delivery. They will also be offered the opportunity to return to Yale at 12-months (immediately after the end of the 6-month counseling sessions) to have weight and DEXA measured.

Additional Information

Official title Lifestyle, Exercise and Nutrition (LEAN) Study 2
Principal investigator Melinda L Irwin, PhD, MPH
Description We will conduct a two-armed study comparing a combination of an in-person and telephone weight loss program compared to usual care/wait list in 100 breast cancer survivors. Women will be randomized into one of the 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.
