Cardiovascular disease (CVD) is a serious health concern for American Indians, but there have been few behaviorally based programs to lessen CVD risk among this population. The purpose of this study is to evaluate whether a Web-based program, in addition to usual medical care, can lower CVD risk factors among American Indians who have type 2 diabetes and a high risk of developing CVD.

Study summary:

Cardiovascular disease (CVD) is a leading cause of death among American Indians. Significant risk factors for CVD within the American Indian population include type 2 diabetes, tobacco use, poor dietary and physical activity habits, and poor medication and treatment adherence. Despite the fact that these risk factors can be reduced through behavior change, there have been few behaviorally based interventions aimed at American Indians to lessen their CVD risk. Research has shown that medical care is moving away from sporadic, standard doctors' office visits to a more continuous and interactive relationship with health care providers. A Web-based program that allows people to interact with remotely located doctors who can answer questions and provide advice may be beneficial at increasing treatment adherence and lowering CVD risk. This study will evaluate the use of a Web-based program at lowering CVD risk among American Indians with type 2 diabetes. Researchers will also analyze the cost-effectiveness of the Web-based program and the possible healthcare cost savings. This 3-year study will enroll American Indian adults at high risk for CVD. Participants will be randomly assigned either to usual care at their local health facility or usual care plus the Web-based program. Participants using the Web-based program will have access to a Web site that will allow them to interact with two remotely based doctors. Participants will be able to send e-mail and instant messages to ask questions and receive information, advice, or motivational messages from the doctors. Participants will periodically enter their blood glucose test results and complete questionnaires online. Study visits, occurring twice a year for 3 years, will include blood pressure and body mass index (BMI) measurements, blood collection, and smoking status assessments.
