Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In sum, excess body weight and inactivity have emerged as strong avoidable causes of postmenopausal breast cancer, with the greatest potential for primary prevention occurring during the premenopausal years. However, surprisingly, no study to date has examined the effects of a standard behavioral weight loss intervention on breast cancer risk markers in premenopausal women. Understanding the effects of weight loss in premenopausal women is a critical next step in existing research and will inform the development of future breast cancer primary prevention programs. The purpose of this study is to determine the feasibility of recruiting, treating, and retaining 20 overweight/obese women in a 12-week randomized control trial examining feasibility and effects of a behavioral weight loss program on breast cancer risk markers in premenopausal women. Participants will be randomly assigned to either a 12-week comprehensive behavioral weight loss program (n=10) or control condition (n=10). All women will be assessed at baseline and after 3 months of treatment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Comprehensive behavioral weight loss

The group will be implemented to induce a 6% weight loss over 3 months. The lessons will follow protocols from the Look AHEAD trial and Diabetes Prevention Program. This behavioral program has been shown to promote long-term weight loss and a reduction in diabetes and cardiovascular risk factors, and is based on the social cognitive theory.

Group Type ACTIVE_COMPARATOR

Behavioral Weight loss

Intervention Type BEHAVIORAL

Intervention groups will meet weekly for 12 weeks. Weekly meetings will focus on weight loss in women age 30-45 through behavioral weight loss topics. These topics are designed with the Look AHEAD protocols.

Education and Support Control group

Participants in this group will receive support and education about healthy eating and activity with lessons based on the Look AHEAD support and education control condition. Participants will attend monthly closed group meetings and meetings will be designed to promote retention but not weight loss.

Group Type NO_INTERVENTION

No interventions assigned to this group
