About
The purpose of this pilot is to assess the feasibility and potential effectiveness of three specific e-health approaches. One approach, SparkPeople.com, involves the use of social media and can be accessed through a free website. This approach has the potential to provide support through an on-line community as well as a number of diet/weight and physical activity related tools. A mobile phone application is also available for those with smart phones. The second approach, BodyMedia, involves the use of an objective monitoring device that tracks all activity. This information can be uploaded to a website to provide ongoing monitoring and feedback about activity and energy expenditure. The third approach, P90X, involves a DVD based resistance focused exercise program. While DVD programs are not necessarily considered e-health, participants will be encouraged to participate in online community forums associated with the program. All participants, regardless of randomization, will be given 4 point of decision prompts that are laminated 8.5x11 posters encouraging healthier behaviors to display in various areas of their home.
The specific aims are:
Full description
This is a pilot study designed to better understand what elements/strategies help to engage Operations Enduring Freedom and Iraqi Freedom (OEF/OIF) veterans in an e-health program for promoting weight loss and increasing physical activity. These data will be used as pilot information for a larger study to assess the effectiveness of using an e-health approach to promote weight loss and increase physical activity among post-deployment OEF/OIF veterans who are at risk for developing diabetes. Additionally, we seek to recognize any effects of the intervention on other health-related outcomes, such as stress, depression or other mental health measures, chronic pain, sleep, quality of life, satisfaction with care/ Veteran Affairs Health system, employment status, social support/connectedness.
Post-deployment OEF/OIF veterans worry about gaining weight and believe regular physical activity is beneficial, yet many don't exercise due to health problems and/or chronic pain. Healthy eating combined with physical activity are key strategies in maintaining or losing weight and is important in preventing diabetes, cardiovascular disease and other preventable illnesses as well as managing many mental health conditions and reducing chronic pain symptoms. In addition, maintaining or improving physical activity/exercise may be an effective strategy for addressing other post-deployment issues: stress, social issues.
E-health strategies may be an effective and potentially preferred as well as efficient (cost-effective) way to deliver or assist OEF/OIF veterans with health and lifestyle related health behaviors. There is a growing array of e-health tools, technologies and approaches to assist people with diet-related issues (for weight loss or maintaining a healthy weight) and to encourage physical activity. This includes cell phone applications, objective monitoring devices such as pedometers and web-based programs (as well as combination of these different strategies). However, the most effective and efficient way to encourage healthy eating and weight loss/maintenance or promote physical activity remains an open question and which tools and technologies might best engage the OEF/OIF veteran population in addressing these lifestyle issues is yet to be determined.
OEF/OIF Coordinators will include the study recruitment flyer in their initial informational mailing to new OEF/OIF veterans and publish the flyer in their monthly newsletter. The recruitment flyer will encourage interested veterans to contact study staff via a toll free number (where they will leave a message) or email. During one-on-one meetings, Coordinators will identify overweight and obese OEF/OIF veterans who are interested in losing weight with physical activity and with the veterans permission will forward the veterans name and phone number to the research study staff by leaving a voice mail on the study phone line. During these meetings, the OEF/OIF Coordinators will also provide basic information regarding the program and provide the Veteran a recruitment flyer. Recruitment flyers will also be posted at strategic locations around the VA with the approval of Public Affairs. Should study staff fail to meet recruitment goals through the assistance of the OEF/OIF Coordinators and posted flyers, primary care physicians (PCPs) will also be educated on the study and given study recruitment flyers to give to potentially eligible patients. With the permission of the veteran, PCPs will forward the veterans name and phone number to the research study staff by leaving a voicemail on the study phone line.
Potential participants will be contacted by phone to be screened for eligibility. If eligible, participant will be asked to come to the Ann Arbor Veterans Affairs Healthsystem (VA) for a 1 ½ to 2 hour enrollment session. Patients will be consented at the start of this enrollment visit, prior to the commencement of any research activities.
All research activities are outpatient. This pilot study will be a crossover study of two 6-week programs. The participant will be involved for 15 weeks.
The three home base diet and exercise programs we are testing are:
Thirty OEF/OIF veterans with body mass index (BMI) > 30 will be recruited to test the diet and exercise programs. Each veteran will test only two of the three programs described above.
Participants will be informed about the study by OEF/OIF coordinators, medical providers or by reading posters about the study posted in outpatient areas in the Ann Arbor VA Medical Center. Contact information for veterans who express an interest and give permission will be forwarded to the research staff. Research staff will call the potential participant on the phone, briefly describe the study and then complete a short eligibility screening questionnaire. Eligible and interested participants will schedule an initial in person study visit.
At the initial study visit, participants will
Participants will then test the diet and exercise program at home for 6 weeks.
. At this second visit, the cross over visit, participants will
Participants will then test the second program at home for 6 weeks.
Participants will then arrange with the study coordinator to return the equipment and materials for the second intervention tested, complete a third online survey and a second interview.
Participants may choose to complete the study without a third VA visit. They would return equipment and materials by mail at the VA's expense, complete the final survey online from home and complete the final interview by phone. Study staff will ask participant for self-reported weight measurement if the final visit is done remotely. For participants who do come to the VA for the final assessment, we will also recheck their weight.
Study staff may contact participants by email or phone to remind participants to complete surveys, upcoming phone interviews, and upcoming research visits. If participant does not complete survey online, study staff will offer to mail the survey for participant to complete at home (including a return envelope), or doing the survey by phone.
If participants test the SparkPeople.com website, they will receive an email from study staff with video clips that describe the website in further detail. The will also receive emails directly from Sparkpeople.com depending on how they set their profile.
If participants test the BodyMedia fit device, BodyMedia will send an email directly to the participant with directions on setting up their account.
All three of the diet and exercise programs we are testing in this study are commercially available home exercise programs and they are not programs developed by or delivered by the VA or VA staff.
Please note: At initial study visit, participant is randomized to 2 of the 3 possible interventions.
