FEASIBILITY AND ACCEPTABILITY OF A BEVERAGE INTERVENTION FOR HISPANIC ADULTS

We propose to 1) assess the feasibility and acceptability of a prescribed beverage intervention in 50 obese Hispanic adults ages 18-64 years over 6 weeks; 2) assess preliminary effects of the beverage intervention on cholesterol and triglyceride levels as well as other markers of health such as blood pressure, glucose and markers of inflammation. This project, if successful, will provide early evidence that targeting dietary behavior around beverage intake could be a novel and easily adopted approach to reduce the burden or delay the onset of metabolic abnormalities in obese Hispanic adults. The expected outcome of the proposed project is the identification of feasible and appropriate beverage intervention strategies to improve engagement and adherence to dietary modification approaches for control of metabolic health indicators in this vulnerable ethnic group.

Study phase: I

Basic eligibility criteria:
Please contact the study coordinator for additional eligibility information.

Individuals will be considered eligible if they meet all of the following criteria:
Self-identify as Hispanic
18-64 years of age
BMI between 30 to 45.0 kg/m² (NOTE: We elected to cap this at 45.0 kg/m² for reliable blood pressure measurement and to avoid recruitment of those on medications for cholesterol control)
Ability to participate in and provide informed consent.

Individuals will be excluded if they meet any of the following criteria:
Diagnosis of diabetes mellitus
History of liver disease
Current medication for glucose control, cholesterol control; uncontrolled BP

Report exercise on ?3 days per week for ? 20 minutes per day over the past 3 months
Report weight loss of ?5% or participating in a weight reduction diet program in the past 3 months
Report plans to relocate to a location that limits their access to the study site or having employment, personal, or travel commitments that prohibit attendance to all of the scheduled assessments
Report consumption of ? 1 cup of green tea daily and not willing to complete 2 week run-in period
Report consumption of ? 1 cup of citrus fruit daily and not willing to complete 2 week run-in period
