Awards & highlights


This trial is testing whether a multimedia health behavior intervention can reduce cardiac risk factors in South Asians, who are a group that is especially at risk for developing these factors at younger ages and at lower body weights.

Who is the study for?
The SAHARA-Trial is for South Asian individuals aged 30 or older living in Ontario or British Columbia, who have not had cardiovascular disease and are not currently pregnant. Participants must be able to use the internet, email, and multimedia devices.Check my eligibility
What is being tested?
This trial tests a 12-month interactive multimedia program designed to improve smoking habits, diet, and physical activity against usual care. It also examines if knowing one's genetic risk for heart attack affects behavior change and cardiac risk factors.See study design
What are the potential side effects?
Since this trial involves lifestyle improvements through an educational intervention rather than medication, side effects are minimal but may include the stress of lifestyle changes or discomfort from increased physical activity.

Prior Approvals
Other Research
Behavioral interventions for cardiovascular disease (CVD) focus on modifying lifestyle factors such as smoking, diet, and physical activity through goal setting, health messaging, and feedback. These mechanisms work by encouraging patients to set specific, achievable health goals, providing continuous health education and reminders, and offering feedback to reinforce positive changes. This approach helps patients adopt and maintain healthier behaviors, thereby reducing risk factors like hypertension, high cholesterol, and obesity, which are pivotal in the progression of CVD.
