Weight Loss App for Obesity

Los Angeles, California
Childhood obesity within the United States has been a growing concern over the past number of years, and if not addressed, leads to detrimental health outcomes for youth as they move into adulthood. The literature suggests that over-eating, especially when framed in terms of food addiction, plays a key role in this epidemic; however, treatment options are time intensive, posing a profound logistical barrier for both the child and parent and often limits or prevents engagement. As research within the field of mHealth has grown, technology-based interventions have gained traction, specifically interactive smartphone applications (apps). Displacement theory, although not new, has been understudied yet provides a strong explanation and treatment plan for addictive type behaviors. The core of this theory posits that problems which one feels they cannot face nor avoid leads to repetitive and irrepressible behaviors; however, if a healthy coping behavior can be learned and utilized, then the unhealthy behavior will cease. The theory lends itself well to being adapted into an mHealth format, making it more easily accessible and more widely used. Grounded in displacement theory, the proposed study aims to develop an app-based weight loss intervention for adolescents with obesity. Information gained regarding the feasibility and acceptability of such an intervention can potentially be replicated and applied to other populations with various addictive behaviors. Helping those with addictive behaviors in a format that has little to no logistical barriers can have a substantial impact on public health. A novel smartphone app will be designed by key stakeholders and refined through the course of the study. 46 total adolescents (14-18 years old) with %BMIp95 will be recruited via various sources (e.g., clinic referrals, flyers, social media advertising) to participate in one of two stages of the study: the beta testing stage or the trial stage. Beta testing will enroll two successive groups of eight teens to test the app for three weeks; participants will be assessed in-person pre- and post-intervention. After each group, the app will be modified to incorporate their feedback in order to promote youth engagement. The trial stage will enroll 30 adolescents to participate in a four-month intervention; participants will complete three assessments, baseline, post-intervention (both in-person) and one-month post-intervention (either in-person or virtually). The study will examine engagement and satisfaction with the app, as well as the intervention's impact on clinical outcome measures (weight and BMI, diet and snacking, and addictive behaviors related to food and substance use) and potential mediators/moderators (motivation for change, perceived stress, and distress tolerance).

Bariatric Surgery for Obesity

Los Angeles, California
Most research to date on bariatric surgery outcomes has been about metabolic syndrome, a disorder very effectively treated by bariatric surgery. However, obesity is also associated with many other problems that have received much less attention. Amongst the most troubling of these for patients is dyspnea. Dyspnea results in substantial patient distress that can greatly reduce health-related quality of life. Little is known about the relationship between dyspnea, weight loss, and bariatric surgery. Dyspnea is a complex symptom that may lead to adaptive responses, such as the need to rest as a consequence of even minimal activity or seeking medical attention. The main outcome of the study will be measured using a new state-of-the-science validated HRQOL measure, the Patient Reported Outcome Measuring Information System for Heart Failure (PROMIS+HF 27).

TOTAL Program for Obesity

West Los Angeles, California
Nearly 8 in 10 Veterans meet criteria for overweight/obesity. Three evidence-based treatment options are available within VA (behavioral weight management \[MOVE!\], obesity medications, and bariatric surgery). However, all treatments are significantly underutilized. This study will evaluate the effectiveness of a novel intervention designed to increase obesity treatment initiation and subsequently weight loss within VA. The intervention, Teaching Obesity Treatment Options to Adult Learners (TOTAL), involves an educational video and multiple motivational sessions delivered via telemedicine. If effective, TOTAL could be implemented throughout VA without requiring significant resources and could be integrated into the existing VA behavioral weight management program, MOVE!, which is present at nearly every VA medical center.

Many people struggle not only to lose weight through changes in diet and physical activity, but also to maintain weight loss once they have achieved it. In a previous study, our team designed and deployed a weight maintenance intervention that was delivered through the patient portal of an electronic health record (EHR) and found that patients who tracked their weight, diet, and physical activity and also received coaching had better success with maintaining recent intentional weight loss than patients who tracked but did not receive coaching. The investigators propose to repeat the intervention in a new health care system and train routine health care staff (e.g., medical assistants and nurses) to be coaches, a more sustainable model that will allow ongoing intervention delivery after the proposed study ends. This is a pragmatic randomized clinical Trial with percent weight change at 24 months as the primary outcome. This will be a 2-arm randomized trial that compares the MAINTAIN PRIME lifestyle coaching intervention to a control tracking intervention.

The purpose of this study is to test a randomized, controlled diet and physical activity intervention designed to be simple and address barriers to participation in lifestyle intervention among 16 urinary bladder cancer patients. Aim 1 is to test the feasibility and acceptability of a novel, peri-operative lifestyle intervention, "The Boost Box", among bladder cancer patients receiving cystectomy with or without neo-adjuvant chemotherapy. Aim 2 is to measure the feasibility of collecting data on the intervention effects on complication rate, nutritional status, weight loss, and quality of life post-surgery among bladder cancer patients receiving cystectomy ± neoadjuvant therapy. Secondarily, we will determine the magnitude of association between study group and outcomes to inform power calculations in a future, well-powered trial. Participants will: * attend two dietetic consultations at baseline and post-surgical recovery where nutritional status will be evaluated with patient-generated subjective global assessment (PG-SGA) * complete baseline questionnaires (TCC, FACT-BI-Cys, Short 2012, FAACT, Godin) * receive weekly BOOST boxes * complete pre-surgery weekly BOOST check ins * complete post-surgery weekly BOOST check ins * complete an ASA food recall pre and post-surgery * complete an exercise familiarization consult * record weekly resistance and aerobic exercise performed at home * complete a 6 month follow-up questionnaire * receive compensation Researchers will compare to a Usual Care group to determine differences that could be attributed to the BOOST Box intervention.

Weight Loss for Obesity

Boulder, Colorado
Changes in adipose tissue biology are now recognized as a key factor underlying the increased risk of metabolic and cardiovascular disease with obesity. Clinical interest in adipocyte-derived extracellular vesicles (Ad-EVs) has intensified due to their potential as circulating biomarkers of adipose tissue health and systemic messengers, regulators and mediators of cardiometabolic health and disease with obesity. The investigators hypothesize that elevated Ad-EVs in adults with obesity will be negatively associated with endothelium-dependent vasodilation. Furthermore, the investigators hypothesize that in adults with obesity, intentional weight loss-induced reduction in circulating Ad-EVs is associated with greater endothelium-dependent vasodilation.

Semaglutide for Obesity

Aurora, Colorado
Glucagon-like peptide 1 receptor agonists (GLP-1RA), such as Ozempic and Wegovy, have been rapidly adopted for the treatment of obesity in both youth and adults. However, despite this rapid adoption and the known GLP-1RA mechanism of action for weight loss, which targets brain circuits responsible for appetite and eating behaviors, almost nothing is known about how these drugs affect the brain in youth who are treated for obesity, or how these drugs affect the brain of youth differently from adults. The goal of the current study is to compare youth and adults with obesity who are treated a GLP-1RA and measure potential difference in GLP-1RA associated change in brain function, appetite, and eating behaviors.

Four in five Veterans have overweight or obesity. However, few eligible Veterans achieve meaningful weight loss in VA's national MOVE! Weight Management Program. Family and friends strongly influence a person's health behaviors and weight. Including a close family member or friend in weight management may improve weight management outcomes. This study will test whether an 14-week, 8-session virtual weight management program that includes Veterans and a support person (e.g., family member or friend) leads to weight loss. The investigators will also test whether the program leads to improvements in weight-related health behaviors, including physical activity and diet, and relationship quality.

Weight Loss for Obesity

Aurora, Colorado
The goal of this intervention study is to learn about how weight loss impacts molecular signaling of intermuscular adipose tissue (IMAT) in individuals with obesity. The main question it aims to answer is how inflammatory molecules secreted by IMAT promote muscle insulin resistance and inflammation, and how these same molecules are diminished after weight loss. Following screening visits involving body composition measures, blood testing, strength testing, and a thigh muscle biopsy, participants will go through a 12-week dietary intervention for weight loss. After 12 weeks, this will be followed by the same testing and biopsies that were completed before the intervention. Researchers will then compare outcomes of individuals who lost weight to individuals who did not lose weight.

The use of continuous glucose monitoring (CGM) in earlier data has inspired behavioral changes leading to improved adherence to an exercise plan in individuals and eating habits in people with diabetes. Mobile health (mHealth) platforms provide satisfactory, easy-to-use tools to help participants in the pursuit of weight change goals. We hypothesize that the use of CGM data and the Signos mHealth platform will assist with weight control in a population of people with type 2 diabetes mellitus who are not using insulin.

Dietary Strategies for Obesity

Palo Alto, California
The goal of the Reset trial is to learn about the optimal combination of dietary behavior strategies in a fully digital weight loss intervention. The intervention is designed for adults with overweight or obesity. The investigators will examine the impact on weight loss of four dietary strategies: 1) limiting Red Zone Foods (i.e., foods that are high in calories and low in nutrition), 2) limiting eating windows, 3) increasing protein intake, and 4) increasing fiber intake. Each of these strategies will include goal setting, daily self-monitoring, and tailored feedback. The investigators will recruit 208 participants. Broadly, adults with overweight or obesity who live in the U.S. will be eligible. The weight loss intervention will last 12 weeks. All participants will be asked to track their body weight daily and complete weekly behavioral lessons and action plans to promote healthy eating and physical activity. All study tasks will occur remotely. Assessment of body weight and survey measures will occur at the beginning of the trial ("baseline"), and at 1 month and 3 months. The Multiphase Optimization Strategy (MOST) framework will be used to identify which combination of the dietary behavior strategies results in the greatest weight loss. In total, there will be 16 treatment conditions.

Why Other Patients Applied

"I have tried to lose weight, but as I get older, it becomes harder and harder. I have lost weight in the past through diet and exercise, but it has been more difficult to accomplish as I age."

"I have a heart condition, and my fat is all in my chest, surrounding my heart. It's hard for me to exercise because my legs are thin and the upper body weight is too much — putting strain on my leg joints. It’s a vicious cycle. I am also post-menopausal, which adds additional weight loss difficulty. I also have stress with being a full time caregiver for my mom. I'm interested in trying a clinical trial."

DK
Obesity PatientAge: 56

"I changed my diet in 2020 and I’ve lost 95 pounds from my highest weight (283). I am 5’3”, female, and now 188. I still have a 33 BMI. I've been doing research on alternative approaches to continue my progress, which brought me here to consider clinical trials."

WR
Obesity PatientAge: 58

"I need to lose weight because it's affecting my knees. I've already had a knee replacement and the second one is happening on the left knee in a few months. I've participated in a study in the past for a skin-related issue, and had a good experience. That's why I'm interested in joining a study for wieght loss."

KI
Obesity PatientAge: 69

"I am applying for my daughter. She turns 12 this year and is overweight. She's 5'4" and 176 pounds. Would be great to enroll her in a clinical trial to see if this form of care could work for her. Realize that there's no guarantee, but I support her and we'd like to give it a try."
