About this study

Official title: Reducing Breast Cancer Risk Through Modifying Body Composition and Decreasing Inflammation in Normal Weight Women

This trial studies how well a lifestyle intervention works in reducing breast cancer risk through changing body composition and decreasing inflammation in normal weight women. This trial may help researchers learn more about diet and exercise programs designed to decrease body fat in postmenopausal women who are of normal weight but have an elevated risk of breast cancer because of excess body fat.

Read the detailed description

PRIMARY OBJECTIVE:

  1. Evaluate the feasibility of a diet and exercise intervention to decrease body fat in postmenopausal women with normal body mass index (BMI) but high body fat (trunk fat mass 9.4 kg, the 50th percentile of normal BMI women in the Women's Health Initiative [WHI]).

SECONDARY OBJECTIVE:

  1. Assess preliminary efficacy of the intervention by evaluating the post-intervention differences between the intervention and control groups in:

IIa. Circulating markers of inflammation and metabolic dysfunction linked to both excess adiposity and breast cancer (high sensitivity C-reactive protein [hsCRP], fasting insulin, leptin, IL-6, triglycerides, sex hormone binding globulin [SHBG], adiponectin, and high density lipoprotein [HDL] cholesterol).

IIb. Body composition body fat, trunk fat mass, fat mass, lean mass, fat-free mass).

EXPLORATORY OBJECTIVE:

  1. Exploratory outcomes include fitness (oxygen consumption VO2 peak, sit-to-stand test), behavior (physical activity, energy intake, macronutrient consumption), and quality of life (global health-related quality of life, physical functioning, sleep, menopausal symptoms).

OUTLINE: Participants are randomized to 1 of 2 groups.

GROUP I: Participants complete lifestyle intervention consisting of 1-3 sets of high-resistance circuit training sessions per week, up to 150 minutes of aerobic training per week, and diet recommendations from a health coach or registered dietitian twice per week for 16 weeks.

GROUP II: Participants are placed on a wait-list and then complete lifestyle intervention after 4 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Eligibility Rate

    Eligibility rate will be calculated as the number of eligible women identified divided by the total number completing a DXA scan. Criteria for feasibility will be defined as an eligibility rate of ≥ 40%

    Measured: 4 months

Secondary outcomes (2)
  1. Intervention Adherence

    Intervention adherence for an individual is defined as attending at least 22 of the sessions with the personal trainer and at least 11 of the health coaching sessions. The intervention adherence at the study level is then defined by the percentage of participants adhering to the intervention. Criteria for feasibility will be defined as a study intervention adherence rate of ≥ 75%

    Measured: 4 months

  2. Retention Rate

    Retention will be assessed by the percentage of participants completing the 4-month study assessments. Criteria for feasibility will be defined as a retention rate of ≥ 80% in each arm.

    Measured: 8 months

Questions about this trial

What is this clinical trial studying?

A study testing Aerobic Exercise, Dietary Intervention and Quality-of-Life Assessment in people with Breast Carcinoma, run by M.D. Anderson Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 12 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Apr 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Eligibility Rate (time frame: 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2026.
