Outcomes
Primary Outcome Measures
Effectiveness of a 6 month culturally-specific multi-media intervention on Heart Health Risk
To test the effectiveness of a 6 month culturally-specific multi-media intervention which provides health messaging and feedback regarding optimal strategies for individuals greater than 30 years to improve their dietary habits, sedentary behaviours, physical activity, and tobacco use.
Secondary Outcome Measures
Influence of knowledge of personal genetic risk for Myocardial Infarction on health behaviours
To determine if knowledge of personal genetic risk for Myocardial Infarction (MI)and Diabetes influences the health behaviours associated with MI risk factors.
Change in the MI risk score and clinical events
To determine the change in the MI risk score and clinical events including MI, death, development of new diabetes, and development of new hypertension over time in all people screened for entry into the randomized intervention.

5. Study Description
Brief Summary
People who originate from the Indian subcontinent known as South Asians are the fastest growing group of non-white Canadians. They suffer an excess prevalence of abdominal obesity, type 2 diabetes and heart disease. They also develop these risk factors at significantly lower body weight and at younger ages compared to people of European origin. The purpose of SAHARA (South Asian HeArt Risk Assessment) Pilot, is to recruit 400 South Asians from Ontario, who use the internet, email and other multimedia devices. Among these participants the investigators will compare the effectiveness of a 6-month interactive multi-media health behaviour intervention to usual care in reducing cardiac risk factors. This intervention enables participants to set their health goals and provides health messaging and feedback designed to improve their smoking, dietary habits and physical activity. In addition, the investigators will test if knowledge of genetic risk for heart attack influences behaviour change and their heart health risk factor profile. The information generated from SAHARA will enable individuals, physicians, health professionals, and policy makers to develop risk factor modification programs to prevent cardiovascular disease in this high-risk group.
Detailed Description
Introduction: Coronary heart disease (CHD) remains the major cause of disease burden globally, and the rising prevalence of overweight, obesity and adult onset diabetes is predicted to potentiate the CHD epidemic in developing countries, and in high risk populations, including people who originate from the Indian subcontinent (South Asians). More than 1.2 million people of South Asian origin live in Canada and they are the fastest growing group of non-white Canadians. Our previous work among South Asians has shown that, compared to white Caucasians in Canada, they suffer from a 2.5 times excess prevalence of elevated glucose (dysglycemia), and CHD. They also develop abnormal glucose, lipids (elevated apolipoprotein B & reduced apolipoprotein Al) and blood pressure at significantly lower body mass index values compared to white Caucasians (21 vs. 30). Successful interventions which prevent or improve myocardial infarction (MI) risk factors among South Asians are urgently needed.
Objectives: Among South Asian men and women ≥ 30 years who live in Canada we propose:
To test the effectiveness of a culturally-tailored multimedia intervention designed to improve health behaviours including dietary habits, sedentary behaviours, physical activity, and tobacco use, in order to improve their MI risk factor profile.
To test if knowledge of genetic risk for MI as determined by the 9p21 variant genotype influences behaviour change and MI risk factor profile.
To determine the change in the MI risk score and clinical events including MI, death, development of new diabetes, and development of new hypertension over the 6 months follow-up.
Design & Methods: People of South Asian ancestry defined as people whose ancestors originate from the Indian subcontinent (India, Pakistan, Bangladesh and Sri Lanka) ≥ 30 years age will be eligible for SAHARA. Subjects with no access to e-mail, text messaging or smart phones and who have suffered previous coronary heart disease will be excluded. 400 subjects will undergo a brief cardiac risk factor assessment including collection of data on questionnaire, physical measurement (i.e. weight, height, waist and hip circumference, and blood pressure), and a blood sample will be collected to measure apolipoproteins and glucose. All eligible and consenting subjects will be randomized 1:1 to intervention versus control. The intervention group will include goal setting, self monitoring and participants will receive regular health messaging using electronic media regarding smoking, dietary habits & physical activity. The control group will receive usual advice and no regular health messaging. The intervention will last for 6 months after and the effectiveness of this intervention will be evaluated using the change in the cardiac risk score after 6 months.
Summary: South Asians are the fastest growing group of Canadians. They suffer an excess prevalence of cardiac risk factors and MI at a younger age compared to people of European origin. The SAHARA project will enable us to use simple but validated tools to assess the MI risk profile among South Asian men and women from Ontario, and we will test a culturally-tailored multimedia intervention to determine if improvement in the MI risk factor profile can be achieved and sustained. If this intervention is successful it will be easily scalable, and has the potential to be delivered to a large proportion of the South Asian community in Canada.
