Veterans Walk for Health Study
Veterans Walk for Health Study
The objective of this study is to determine whether a tailored web-based system for providing
 feedback on walking step-counts, in combination with regular nutrition counseling, can
 improve weight loss over nutrition counseling alone in patients with heart disease.
Objective: This proposal was developed at the request of, and with input from, the Research
 Council of the Department of Veterans Affairs' (VA's) National Advisory Board for Nutrition
 and Food Services, in an effort to address obesity, a major health problem for VA patients.
 The prevalence of obesity in the United States has been increasing at an alarming rate. As a
 result, obesity related chronic diseases such as diabetes are also increasing in prevalence.
 While interventions that focus only on dietary changes can result in significant weight loss,
 the lost weight is often rapidly regained. Physical activity, when added to a dietary weight
 loss program, not only increases the initial weight loss but it also can play a critical role
 in preventing weight regain. The primary objective of the proposed study is to test the
 efficacy of a low-cost, innovative weight loss program targeting lifestyle physical activity
 and diet in individuals with cardiovascular risk factors or disease.

 Study Design and Methods: In this 3 year multi-site randomized controlled trial, the
 investigators will recruit overweight and obese veterans with cardiovascular disease risk
 factors or known cardiovascular disease who have been referred for nutritional counseling or
 who have responded to advertisements for the study. Research participants will be randomized
 to one of three study groups:

 -  nutritional counseling alone;

 -  nutritional counseling with simple pedometer feedback; and

 -  nutritional counseling, with both simple pedometer and enhanced pedometer (web-based)
 feedback.

 Each participant will have 5 visits with a dietitian in the course of 6 months. Participants
 randomized to receive pedometer feedback will review objectively monitored step-count data
 during their nutritional counseling sessions and will use the data to set new step-count
 goals. The primary outcome, weight loss, will be assessed at the sixth and final session at
 the end of the 6-month intervention. Enhanced pedometers that can monitor step-counts
 throughout the day and upload time stamped step count data to a central computer will be used
 to monitor adherence to a walking program.
Inclusion Criteria:

 -  Is newly referred from a VA physician for nutritional counseling or has responded to
 an advertisement for the study - Has one of the following diagnoses: diabetes,
 coronary artery disease, hypercholesterolemia, hypertension, obesity.

 -  Is ambulatory and able to comfortably walk at least one block.

 -  Has a body mass index (BMI) of 28 or greater.

 -  Is not already regularly active (30 minutes a day, 5 days a week of moderate intensity
 physical activity).

 -  Is in the contemplation or preparation stage of readiness to become more physically
 active.

 -  Is willing to try a walking program.

 -  Can communicate comfortably in English.

 Exclusion Criteria:

 -  Has attended a nutritional counseling session in the past 28 days.

 -  May be at risk for adverse cardiovascular events with a walking program--specifically
 participants who:

 -  have symptoms of cardiovascular disease (CVD) while walking;

 -  have been told by a physician that walking might be dangerous; or

 -  have a stress test scheduled in the next two months.
