Lifestyle Intervention for the Reduction of Breast Cancer Risk in Normal Weight Women

2020-02-17 18:20:55 | BioPortfolio


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.



I. 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]).


I. 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).


I. 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.

Medical and Biotech [MESH] Definitions

Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.

Alternating sets of exercise that work out different muscle groups and that also alternate between aerobic and anaerobic exercises, which, when combined together, offer an overall program to improve strength, stamina, balance, or functioning.

A measurement index derived from a modification of standard life-table procedures and designed to take account of the quality as well as the duration of survival. This index can be used in assessing the outcome of health care procedures or services. (BIOETHICS Thesaurus, 1994)

Activities and programs intended to assure or improve the quality of care in either a defined medical setting or a program. The concept includes the assessment or evaluation of the quality of care; identification of problems or shortcomings in the delivery of care; designing activities to overcome these deficiencies; and follow-up monitoring to ensure effectiveness of corrective steps.

A generic concept reflecting concern with the modification and enhancement of life attributes, e.g., physical, political, moral and social environment; the overall condition of a human life.
