This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The number of obese individuals in the United States is increasing. For African Americans, the increase in obesity has been disproportionate. For example, typical weight loss interventions routinely show less weight loss for African Americans compared to Caucasians. Weight loss improves cholesterol, blood pressure, risk of hypertension, blood glucose, and can prevent the development of type 2 diabetes. Therefore, many of the benefits that African Americans could receive from weight loss are not realized. Using a period of formative assessment to gather information regarding the key cultural variables, we propose to develop and implement a culturally appropriate behavioral intervention for weight control based on the EatRight dietary pattern. EatRight is a 12-week lifestyle-oriented weight control program based on the concept of "time-calorie displacement," which emphasizes the ingestion of large quantities of high-bulk, low-energy-density foods and moderation in high-energy-density foods. We will use qualitative methodologies to inform our development of the tailored dietary intervention. The primary outcome is change in weight, with secondary measures of markers of cardiovascular risk including blood pressure, lipids, glucose, and insulin. The successful completion of this project will lead to a widely usable dietary intervention with demonstrated effectiveness in African Americans.
