Brief Summary:

Recent American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines recommend lifestyle modification for patients with blood pressure >= 130/80 mmHg. 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 untreated, elevated blood pressure.


Condition or disease Intervention/treatment Phase
Blood Pressure High Blood Pressure Dietary Modification Overweight and Obesity Behavioral: Self-Guided Approach Behavioral: Dietitian-led Approach Not Applicable

Detailed Description:
Goals that all participants will be instructed to target include: 1) weight loss >=3% at 3 months; 2) consume a healthier dietary pattern (high in fruits, vegetables, whole grains, low-fat dairy, vegetable/fish/poultry sources of protein, healthier sources of fat, and avoid sugar and salt); 3) reduce sodium intake to <2300 mg/d; 4) at least 180 min/wk of moderate-intensity physical activity.

Arm Intervention/treatment
Active Comparator: Self-Guided Approach

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 BMIQ (www.bmiq.com), an evidence-based program developed by Dr. Louis Aronne at Columbia University, which includes program materials for weight loss and leading a healthy lifestyle; 3) LoseIt (www.loseit.com), a meal-logging app that integrates seamlessly with the BMIQ website.

Behavioral: Self-Guided Approach
For a 12-week period, patients will be asked to enter dietary information into the LoseIt mobile app.

Experimental: Dietitian-led Approach

In the dietitian-led arm, dietitian will use motivational interviewing in 15-30 minute telephone calls with participants. The BMIQ website will be used to share participant dietary data (LoseIt) and weight data with dietitians.

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 BMIQ; 3) LoseIt (www.loseit.com), a meal-logging app that integrates seamlessly with the BMIQ website.

Behavioral: Dietitian-led Approach
For a 12-week period, patients will be asked to enter dietary information into the LoseIt mobile app. Dietitians will access this information and provided personalized motivational interview phone calls on a weekly basis.




Primary Outcome Measures :
  1. Change in 24-hour Systolic Blood Pressure [ Time Frame: Baseline to 12-week follow-up ]
    Measured by 24-hour ambulatory blood pressure monitoring (SpaceLabs Ontrak)


Secondary Outcome Measures :
  1. Change in Total Healthy Eating Index - 2015 score [ Time Frame: Baseline to 12-week follow-up ]
    Assessed by Viocare Food Frequency Questionnaire (score 0-100, 100=best possible score)

  2. Change in Weight [ Time Frame: Baseline to 12-week follow-up ]
    Weight measured at baseline and 12-week visits using a calibrated scale without shoes

  3. Change in Waist Circumference [ Time Frame: Baseline to 12-week follow-up ]
    Measured using Gulick II tape measure

  4. Change in 24-hour diastolic blood pressure [ Time Frame: Baseline to 12-week follow-up ]
    Measured by 24-hour ambulatory blood pressure monitoring (SpaceLabs Ontrak)

  5. Change in Clinic systolic blood pressure (SBP) [ Time Frame: Baseline to 12-week follow-up ]
    Measured by average of 3 readings using Omron HEM 907XL

  6. Change in Clinic diastolic blood pressure (DBP) [ Time Frame: Baseline to 12-week follow-up ]
    Measured by average of 3 readings using Omron HEM 907XL

  7. Change in Physical Activity (metabolic equivalent of task [MET]-minute per week [ Time Frame: Baseline to 12-week follow-up ]
    Measured by International Physical Activity Questionnaire (IPAQ) Short Form


Other Outcome Measures:
  1. Change in individual components of Healthy Eating Index score [ Time Frame: Baseline to 12-week follow-up ]
    Each individual component of the Healthy Eating Index score will be examined
