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.
