Integrated Weight Loss Technologies for Weight and Blood Pressure Control in Urban Clinics

Obesity is a serious health problem in the United States, particularly among lower income
and racial and ethnic minority populations. These populations have a high risk of developing
heart disease and high blood pressure, and obesity is likely a contributing factor for both
conditions. African-Americans, in particular, experience an earlier onset of high blood
pressure and suffer more severe health consequences as a result, than do other racial and
ethnic groups. This study will evaluate the effectiveness of a lifestyle modification
program that will focus on reducing blood pressure levels and encouraging weight loss among
patients at community health centers that serve a primarily low-income, ethnically diverse
population. Researchers will also evaluate the cost effectiveness of the lifestyle
modification program.

This 2-year study will enroll people who have high blood pressure. Participants will attend
a baseline study visit to complete health questionnaires. They will then be randomly
assigned to either receive usual care along with printed materials about maintaining a
healthy weight or take part in the lifestyle modification program that incorporates health
information technologies. Participants assigned to the program will visit the BFBW study Web
site several times a week to review educational and motivational information. They may
receive automated weekly phone calls that will prompt them to answer questions and assist
them in setting goals for losing weight and managing their blood pressure. A study
researcher will call participants every 6 weeks to discuss any problems and to invite
participants to take part in optional walking groups or other group activities. Participants
will attend group support sessions every other month and will wear a pedometer to track
their walking habits. For all participants, study visits will occur at baseline and Months
6, 12, 18, and 24. All visits will include weight and blood pressure measurements, health
questionnaires, and physician referrals if needed.

Inclusion Criteria:

- High blood pressure that is being treated with medication

cause weight gain or prevent weight loss (e.g., corticosteroids, lithium, olanzapine,
risperidone, clozapine)
