About
Compared to the general public, a higher percentage of Veterans are obese or overweight with a weight-related medical condition. The VA currently offers an effective weight management program called MOVE!, but the majority of eligible patients do not attend. Veterans see their primary care providers (PCPs) very frequently, making it an important place to receive information on weight management. However, PCPs often fail to discuss weight management with patients, so interventions are needed to encourage weight management counseling within the team-based care model used in primary care at the VA. Investigators used focus groups, interviews, and other research methods to develop the MOVE! Toward Your Goals (MTG) intervention. This intervention combines online tools, counseling by a health coach, and the team-based care model to deliver weight management information to patients.
Investigators will conduct a randomized controlled trial of 320 Veteran patients and their providers at two VA sites (Manhattan and Brooklyn campuses, New York Harbor Healthcare System) to study the impact of the 12-month MTG intervention when compared to Enhanced Usual Care. Veterans in the MTG intervention arm will take the MTG tool, receive personalized weight management materials, health coach counseling, and go to their scheduled primary care (PC) visit. After the initial visit, MTG-arm Veterans will receive follow up telephone coaching over 12 months. All Veterans will attend follow-up visits at 3, 6 and 12 months to assess body mass index, diet and physical activity, and goal attainment.
The objectives of this study are to: (a) test the impact of the MTG intervention on weight and behavior changes; (b) identify predictors of weight loss in Veterans who use goal setting techniques; and (c) determine the impact of the MTG intervention on primary care team obesity-related counseling practices and attitudes.
Full description
Veterans shoulder a disproportionate burden of obesity and its co-morbidities, including diabetes, hypertension, and hyperlipidemia. Modest weight loss in obese patients through diet and exercise improves health and prevents chronic disease, but primary care providers (PCPs) often fail to adequately counsel patients about their weight due to lack of time and training. Thus, tools and brief interventions are needed to support providers' behavior change counseling. The VA currently offers the MOVE! program to treat overweight and obese patients, but only 9% of eligible patients attend. At the same time, Veterans on average see their PCPs 3.6 times per year, which supports the importance of developing primary care (PC)-based interventions. The United States Preventive Services Task force (USPSTF) recommends the use of the 5As framework (Assess, Advise, Agree, Assist, Arrange [5A]) for counseling patients about weight.
Interactive behavior change technologies utilizing expert system software programs are an innovative way to facilitate 5As counseling to promote behavior change in primary care. These programs perform computerized risk, lifestyle, and theory- based, behavioral assessment to provide computer-generated, tailored advice to patients. They also can provide information to healthcare teams.
Collaborative goal setting can be used to achieve behavior change in this intervention. This construct, a critical component of several behavior change theories and models and corresponding to "agree" in the 5As model, has been widely recommended for health promotion in primary care. Investigators did formative work using key informant interviews with several VA Patient Aligned Care Teams (PACT), MOVE! staff, and focus groups with Veterans demonstrated that goal setting is feasible and acceptable to patients and PACT teamlets, and provided insight on barriers to goal setting, and ways to facilitate goal-setting conversations.
During the development phase of this project, investigators developed a primary care-based intervention called MOVE! Toward Your Goals (MTG) to facilitate weight management within primary care and increase adoption of intensive VA programs such as MOVE!. The MTG intervention uses a new MTG software tool (that the investigators developed) delivered on tablets to facilitate 5As-based weight management counseling with a health coach and healthcare team to promote goal-setting, behavior change, and weight loss in the primary care setting. The Veteran also receives follow up with 12 health coaching calls over 1 year.
Investigators will conduct a large, multicenter (Manhattan and Brooklyn campuses, New York Harbor Healthcare System) randomized controlled trial of 320 subjects, who will be randomized to receive either Enhanced Usual Care or the MTG Intervention.
The objectives of this study are to: (a) test the impact of the MTG intervention on weight and behavior changes; (b) identify predictors of weight loss in Veterans who use goal setting techniques; and (c) determine the impact of the MTG intervention on primary care team obesity-related counseling practices and attitudes.
