September 4, 2008 updated by: Wayne State University

Peer Counseling for Weight Loss in African American Breast Cancer Survivors

The efficacy of peer counseling for weight loss maintenance is being tested in obese and overweight African American breast cancer survivors.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Obesity has adverse effects on breast cancer survival and recurrence, and this may be mediated via the insulin resistance that is associated with obesity. This is a matter of exceptional concern for African-American (AA) breast cancer survivors since a greater proportion of AAs than European Americans (EA) are obese, insulin-resistant and diabetic. This proposal seeks to test the effects of weight loss intervention in obese and overweight AA breast cancer survivors (body mass index 25-40 kg/m2, stage I, II, or IIIA cancer, free of recurrence). Subjects (n=100) will be randomized across 3 arms: 1) control; 2) individualized, dietitian-led counseling; and 3) dietitian-led counseling combined with peer counseling using telephone counseling by trained peers who are AA breast cancer survivors successful at weight control. Psychosocial factors that can affect the extent of weight loss achieved will be assessed, including individual, home and community-level factors. Some of these factors may change when weight loss is achieved and will be assessed both before and after intervention. Genetic polymorphisms that have been shown to be associated with increased body weight, insulin resistance, lipid metabolism, and oxidative stress will be determined and related to both baseline and post-intervention anthropometric and biologic measures. This should further help elucidate inter-individual differences in response to weight loss intervention. The possible beneficial effects of weight loss on the health risks associated with obesity will be evaluated with measures of insulin resistance, insulin-like growth factor and lipid levels in blood samples, as well as with blood pressure and anthropometric measures. The effects of weight loss on these measures have been studied in other obese and overweight populations, but there is little data in breast cancer survivors. Finally, we will attempt to determine if beneficial effects of weight loss can be detected in the breast, since this should be related to subsequent breast cancer risk. The breast contralateral to surgery will be subjected to ductal lavage at baseline, 12 and 24 months. The investigators will examine the effects of weight change on markers of oxidative stress in the breast nipple aspirate fluid that is obtained as part of the lavage procedure. Levels of lipid peroxidation are very high in this fluid and have been related to both nuclear atypia and breast cancer risk. The nuclear morphology of epithelial cells obtained by ductal lavage therefore will be quantified as well. Weight loss in obese and overweight AA breast cancer survivors should improve both psychosocial function and biological indicators of health risks.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
100

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 71 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
weight loss

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
fitness
markers of oxidative stress in blood and breast fluid
markers of cardiovascular health in blood
body fat
