NCT03700710

Brief Summary

American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines recommend lifestyle modification for patients with elevated blood pressure. While eating a Dietary Approaches to Stop Hypertension (DASH)-type diet, increasing physical activity, and weight loss have been shown to reduce blood pressure, limited resources are available in the primary care setting to help patients make these changes. In this study, the investigators will compare the efficacy of a self-guided vs. dietitian-led approach using web-based lifestyle modification tools to reduce weight, improve dietary quality, and lower blood pressure in overweight/obese adults with elevated blood pressure.

Study Arms (2)

Self-Guided Approach

ACTIVE COMPARATOR

In the self-guided arm, participants will receive access to web-based tools to help achieve healthy lifestyle changes to lower their blood pressure. The web-based tools include: 1) a web-based food frequency questionnaire (Viocare FFQ), which will provide a snapshot of participants' dietary habits in the past 6 months as well as personalized recommendations for areas to improve; 2) access to an evidence-based program (Evolve, formerly BMIQ), which includes program materials for weight loss and leading a healthy lifestyle as well as the ability for capturing dietary data entry.

Behavioral: Self-Guided Approach

Dietitian-led Approach

EXPERIMENTAL

In the dietitian-led arm, dietitian will use motivational interviewing in 15-30 minute telephone calls with participants. The web-based tools include: 1) a web-based food frequency questionnaire (Viocare FFQ), which will provide a snapshot of participants' dietary habits in the past 6 months as well as personalized recommendations for areas to improve; 2) access to an evidence-based program (Evolve, formerly BMIQ), which includes program materials for weight loss and leading a healthy lifestyle as well as the ability for capturing dietary data entry. The web platform will be used to share participant dietary and weight data with dietitians.

Behavioral: Dietitian-led Approach

Interventions

For a 12-week period, patients will be asked to access the web platform (Evolve, formerly BMIQ), review educational materials, and enter dietary information. From January 2019 to February 2021, participants used an earlier version of the platform, which was used in tandem with LoseIt (www.loseit.com), a meal-logging app that integrated with the platform. In February 2021, a platform update occurred (Evolve) where the core tenets of the program remained the same and included the dietary data entry directly on the platform.
