Project: Longitudinal Modeling of the Effects of Dietary Intakes on Body Composition and Risk Factors for Coronary Disease in the Women’s Health Trial: Feasibility Study in Minority Populations
Award Year: 2002
Amount of award, fiscal 2000: $121,000.00 fiscal 2002: $34,400.16
Institution: University of Houston
Principal Investigator: Alok Bhargava
Status: Completed
Detailed Objective: This project develops dynamic models to explain selected nutrition-related risk factors for chronic disease among participants in a 12-month randomized trial of a low-fat diet. Results will provide insights into factors influencing success in changing dietary behavior, and the effects of dietary intakes on body composition and other physiological measures of nutritional status.

The project will develop dynamic models to explain weight, waist and hip circumferences, and selected nutrition-related risk factors for chronic disease among participants in the Women's Health Trial: Feasibility Study in Minority Populations, a 12-month randomized trial designed to reduce the percentage energy intakes from fat to approximately 20 percent. The trial collected information on the household incomes, education levels, and dietary intakes, as well as selected psychosocial characteristics, and health behaviors of its 2,200 post-menopausal minority and nonminority women. The dynamic models will incorporate data on participants' anthropometric measures, dietary intakes, clinical measures of nutritional status, and measures of psychosocial functioning obtained at baseline, 6 months, and 12 months. The empirical results will provide insights into changes in dietary patterns of minority and nonminority women following the dietary intervention, factors influencing success in changing dietary behavior, and the effects of dietary intakes on body composition and other physiological measures of nutritional status. In fiscal 2002, additional funding of $34,400 was provided to extend the analysis to a second data set of food stamp program recipients. The expected completion date is October 2003.
