Primary Outcome Measures:
  • Weight loss [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    To examine the effectiveness of using motivational, behavioral interventions aimed at improving physical activity levels and dietary habits to produce weight loss in women with a history of breast cancer.


Secondary Outcome Measures:
  • Feasibility of recruiting breast cancer survivors [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    To examine the feasibility of recruiting, administering, and maintaining interventions in a small sample of women with a history of breast cancer in a community health setting for pilot data.

  • Examination of health outcomes, breast cancer reoccurrence, and mortality. [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    To examine health outcomes, cancer reoccurrence, and mortality in women with a history of breast cancer within the 12 month period via adverse events. Additional procedures include resting ECG, waist circumference, weight, and blood work.

Arms Assigned Interventions
Active Comparator: Group-based Intervention
We randomly assigned 30 individuals to a group-based intervention to promote weight loss through dietary restriction and physical activity.
Behavioral: Group-based Intervention
compared effects of a group-based intervention on weight loss and physical activity.
Active Comparator: Telephone-based Intervention
We randomly assigned 22 individuals to the telephone-based intervention to promote weight loss through dietary restriction and physical activity.
Behavioral: Telephone-based Intervention
compared telephone-based intervention to weight loss and physical activity.

Detailed Description:

This study will be divided into two phases (Phase I and II) that will differ by the intensity of motivational intervention. In Phase I, participants will receive 6 months of intensive weekly group-based or telephone-based motivational, behavior modifying intervention aimed at improving physical activity levels and dietary habits. Phase II will be an additional 6 months of monthly individualized motivational intervention in order to attain and maintain at least 7% body weight loss. All participants will attend an orientation, 2 run-in sessions, and a baseline assessment prior to the intervention. Participants will then be assigned to either the group based intervention or telephone intervention. The first 30 participants will enter into the group-based intervention and the second 30 will enter into the telephone-based intervention. Follow-up visits will be completed at the end of Phase I (week 25) and Phase II (week 50). Up to 60 women with a previous history of breast cancer will participate in this study.
