Efficacy of a Web-based Lifestyle Modification Program in Obese Patients With Cardiovascular Risk Factors

A 6-Month, Randomized Study to Evaluate the Efficacy of a Web-based Lifestyle Modification Program With and Without Telephone Counseling Support

To evaluate the effect of a 6-month web-based lifestyle modification program with and without telephone counseling versus usual care in obese patients with cardiovascular risk factors on:

• Weight Loss
• Waist circumference; blood pressure; total cholesterol, triglycerides, LDL-cholesterol, HDL-cholesterol; glucose and hemoglobin A1c; C-reactive protein.
• Physical activity and eating habits
• Quality of life

1. Male or female 25-70 years of age
2. Obese (BMI ≥ 30 kg/m2 and <40 kg/m2)
3. At least 2 cardiovascular risk factors (diabetes, hypertension or dyslipidemia) i) Hypertension defined by a history of hypertension, treatment of hypertension or BP values >140/90 mmHg in two consecutive office visits ii) High cholesterol defined by an LDL-C ≥130 mg/dL and/or HDL-C <40 mg/dL and triglycerides ≥150 mg/dL iii) Type 2 Diabetes Mellitus defined by a history of diabetes, treatment of diabetes or fasting glucose ≥126 mg/dL in two consecutive office visits
4. Participant must be willing and able to provide written informed consent
5. Participant must be willing and able to comply with study related procedures
6. Participant must have access to Internet and e-mail

Exclusion Criteria:
