History of Changes
  Purpose

We will perform a randomized, controlled trial, the primary aim of which is to assess the effectiveness of a behavioral-based physical activity program in the prevention and treatment of obesity and related co-morbid conditions in a primary care setting. We hypothesize that the prevention and/or reduction of obesity and related co-morbidities in patients randomized to an individualized education and behavior counseling group will be greater by comparison to those randomized to a group that receives standard care alone.

  Eligibility

Ages Eligible for Study:   25 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Men and women between 25 and 65 years of age.
  • Sedentary lifestyle (planned physical activity for the purpose of health one day per week or less).
  • Abdominally obese (waist circumference greater than 88 and 102 cm for women and men respectively).
  • Weight stable (± 2 kg) for 6 months prior to the beginning of the study.
  • BMI between 25 and 34.9 kg/m2 (Because a lifestyle-based intervention alone for obesity reduction is ideal for persons with a BMI greater less than 35, and, that 94% of overweight and obese Canadian adults have a BMI between 25 and 34.9 kg/m2, subjects with a BMI 35 or greater will be excluded).

Exclusion Criteria:

  • Physical impairment which would make the intervention very difficult, or unsafe according to the patient's physician including history of myocardial infarction, stroke, coronary bypass surgery or angioplasty in the last 6 months; peripheral artery disease, unstable angina or ischemia, uncontrolled or insulin dependent diabetes mellitus.
  • Alcohol consumption > 21 drinks per week.
  • Plans to move from the area.
  • Participating in another research study.
  • Clinically judged to be unsuitable for participation or adherence
  • Inability or unwillingness to provide informed consent.
  • For women, planned pregnancy in the next 3 years.
