The purpose of this study is to examine the effect of dietary protein supplements on high blood pressure (BP).

The purpose of this study is to design and demonstrate the feasibility of implementing moderate and intensive environmental obesity prevention programs at major worksites.

The purpose of this study is to implement and evaluate a two-year multi-component environmental intervention to prevent weight gain among city bus drivers at four bus garages. It is hypothesized that transit employees in the intervention garages will gain less weight compared to the transit employees in the control garages.

The purpose of this study is to determine the effect of exercise training on elevated C-reactive protein (CRP) concentrations, an indicator of inflammation, in initially inactive women and men.

To determine the effects of soy on lipids, lipoproteins and lipoprotein subclass in a sample of African-American and white postmenopausal women with low-density lipoprotein (LDL) cholesterol elevations that may increase their lifetime risk for cardiovascular disease but would not qualify for definite pharmacotherapy under current guidelines.

To assess the impact of tamoxifen on development of breast cancer, coronary heart disease, and bone fractures. The National Cancer Institute initiated the prevention trial under its National Surgical Adjuvant Breast and Bowel Project (NSABP). The National Heart, Lung, and Blood Institute provided support to obtain blood pressure and lipid measurements, and lipoprotein and selected coagulation factor measurements in a subsample.

To determine if the increase in low density lipoprotein (LDL) cholesterol at the time of menopause could be ameliorated or prevented by an intensive dietary intervention. Also, to prevent the increase in body weight and associated changes in insulin, glucose, blood pressure, triglycerides, and high density lipoprotein cholesterol during the peri- to postmenopausal period.
