NCT02911753

Brief Summary

This study aims to 1) assess the feasibility and acceptability of a prescribed beverage intervention in 50 obese Hispanic adults ages 18-64 years over 6 weeks; and 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 Arms (3)

Mediterranean Lemonade Consumption

EXPERIMENTAL

All participants will be asked to consume 32 ounces daily of Mediterranean Lemonade. The beverage will be previously prepared and packaged by study personnel. Participants will receive their beverage supply on a weekly basis for a total of six weeks.

Other: Mediterranean Lemonade

Green Tea Consumption

EXPERIMENTAL

All participants will be asked to consume 32 ounces daily of Green Tea. The beverage will be previously prepared and packaged by study personnel. Participants will receive their beverage supply on a weekly basis for a total of six weeks.

Other: Green Tea

Flavored Water Consumption

PLACEBO COMPARATOR

All participants will be asked to consume 32 ounces daily of Flavored Water. The beverage will be previously prepared and packaged by study personnel. Participants will receive their beverage supply on a weekly basis for a total of six weeks.

Other: Flavored Water

Interventions

All participants will be advised to consume all of the beverage assigned (mediterranean lemonade) on a daily basis (rather than save up and consume large amounts on fewer days). The beverages will be prepared in advance by study personnel, refrigerated, and distributed to study participants on a weekly basis. Participants will be provided a daily 32-ounce beverage container for beverage consumption and instructed to clean the container nightly. Participants will also be asked to keep a log of completion of beverage on a daily basis and instructions regarding intake of other beverages will be provided.

Limitations and Caveats

The study was short in duration. It is possible that this was not an adequate amount of time to observe changes in our primary outcomes. In addition, the small sample size may have reduced effect size, thus hindering our capacity to detect changes.
