Behavior Technology Laboratory


  • Tiffany Stewart, Ph.D.


The Behavior Technology Laboratory is dedicated to Translational Research: taking health behavior change programs and technologies from bench (science) to bedside (programs everyone can utilize). The mission of the Behavior Technology Laboratory is to investigate the novel assessment, prevention, and intervention approaches for eating disorders, obesity, and body image disturbance on health behaviors and chronic disease outcomes.


With the dawn of new e-health technologies and population health research models to reach populations who don’t have access to or who are unable to participate in clinical programs and/or specialized healthcare, the Behavior Technology Lab’s work over the years has been focused on developing and testing community-based programs and technology based health tools in order to disseminate prevention and treatment efforts to large populations.

Highlighted work includes:

Military Health & Readiness.  Our Soldiers and their families are not immune to the obesity epidemic. As a part of the Military Health & Readiness projects, the Healthy Eating, Activity, and Lifestyle Training Headquarters (H.E.A.L.T.H.)  program was developed at Pennington Biomedical and represents an ongoing, nearly 20-year  collaborative effort between PBRC and the Department of Defense. The H.E.A.L.T.H. program is designed to aid Soldiers in maintaining healthy weight status, fitness status, combat readiness, and Warfighter performance. H.E.A.L.T.H. also includes programming to aid Soldiers’ family members in reaching overall health and fitness goals. H.E.A.L.T.H.  incorporates cutting edge interactive technology in a Smartphone application for Soldiers and their family members to use wherever they are in the world. H.E.A.L.T.H. has been deployed and tested in several projects, i.e. Ft. Bragg, NC, the New England Reserves, and the Louisiana Army National Guard. As a result of this development and testing, funded by the Department of Defense, the H.E.A.L.T.H. program is currently being disseminated Army-wide as to improve nutrition, fitness, sleep, overall health, and resilience for our technologically advanced fighting force and their families. To date, approximately 15,000 individuals have participated in the H.E.A.L.T.H. program.

Athlete Health & Performance. Given the cost of treating eating disorders (EDs) and the substantial morbidity and mortality associated with these disorders, prevention of EDs has considerable public health significance. Research supports the use of a program targeting small lifestyle modifications in the prevention of ED onset and in reducing ED and obesity risk factors. Research suggests that disordered eating among female athletes is prevalent, and is especially dangerous in female athletes because it increases risk for the Female Athlete Triad (i.e., low energy availability/disordered eating, menstrual disorders, and decreased bone mineral density/ osteoporosis) and subsequent injury. This work includes a federally funded (NIH) controlled trial to test the effectiveness of the FAB program among 500 collegiate female athletes across four university sites.

Children’s Health & Well-Being. Science tells us that if we don't appreciate our bodies, we don't treat our bodies well. How we view our bodies is a key component of successful health behaviors and significantly affects our quality of life. This workshop intervention series teaches children and adults to keep their bodies healthy through nutrition, fitness, sleep, and body image. The experiences gained through these workshops will reframe the dialogue between kids and adults about healthy bodies, while empowering kids to establish positive behaviors and improve their health for the long-term. This workshop series, soon to be accompanied by a Smartphone application, is currently a partnership with the Knock Knock Children’s Museum and Mayor Broome’s Healthy Baton Rouge Initiative. The workshop is currently being deployed at the museum, schools and summer camps throughout Baton Rouge.

Diabetes Model Clinic. In Louisiana, we aren’t obese; we have obesity. Obesity is a disease and in fact, we are one of the states that suffers from the highest rates of the disease. As a result, we also suffer from some of the highest rates of type 2 diabetes. Luckily, we have one of the world’s leader in obesity and diabetes prevention and treatment and has participated in all of the landmark trials targeting these diseases. It is this science that we aim to translate into practical applications and help the citizens of Louisiana. For the first time, Pennington Biomedical Research Center is expanding its mission beyond science to clinical treatment and is opening its doors to the community to treat obesity and type 2 diabetes. This treatment mission is based on 30 years of global research, translating the best science into a community practice model. Pennington has launched a weight-centric type 2 diabetes program for our Louisiana Medicaid recipients, working in collaboration with patients’ existing primary care physicians to make treatment a success. This model clinic is a partnership with the Louisiana Department of Health, and is the first of its kind in offering a comprehensive program combining evidence-based medical management, intensive behavioral intervention, and novel technology to reverse the negative effects of diabetes that affects so many in our state. The state of Louisiana has provided support for the opening of this clinic with a $2 million investment.  If the clinic program model proves practical and cost-effective, a secondary aim of the effort will be to disseminate the treatment model more widely into primary healthcare settings.
