Active clinical trials for "Weight Loss"

Obesity is a serious global public health issue. Many reports have showed that the use of appropriate probiotics can bring benefits to the health of the host and promote the balance of gut microbiota. Clinical experimental data show that the supplement of probiotics can help regulate gut function and weight control, and etc. TCI378 (Lactobacillus plantarum TCI378) is a probiotic extracted from Korean kimchi, and TCI507 (Lactobacillus plantarum TCI507) is a probiotic extracted from the oranges peels. These two strains of probiotics have been verified by in vitro experiments to have the effect of hydrolyzing bile salts, inhibition of the production of fat cells. Therefore, we want to evaluate whether the probiotics TCI308 and TCI507 have effects on reduction of body weight.

In a previous study (NCT04081337), 55 participants with obesity participated on a 18-week lifestyle intervention to reduce their body weight, targeting 10% body weight loss. The participants received tirzepatide (15mg after titration) or placebo during the weight loss intervention. Before and after the lifestyle intervention, energy expenditure (48-h room indirect calorimetry) and body weight and composition (dual-X-ray absorptiometry) were measured, thus enabling the assessment of metabolic adaptation. In this study, participants having provided their consent to be re-contacted will be invited to attend the research center 12,18 and 24 months after completing the lifestyle intervention. Body weight and composition will be measured, aiming to explore the association between metabolic adaptation and changes in body weight and composition after a weight loss intervention. In addition, we will explore whether weight and fat mass changes are different between groups, and whether these effects are mediated by metabolic adaptation.

The investigators propose a randomized controlled clinical trial in 250 women with a history of early stage breast cancer who are overweight or obese with insomnia to test whether a brief, cognitive-behavioral intervention for insomnia (CBT-I) prior to behavioral weight loss (CBT-I+BWL) is superior to a sleep education control (EDU) condition followed by behavioral weight loss (EDU+BWL). The investigators will measure outcomes at baseline, 8 weeks (after completing CBT-I or EDU and prior to BWL), and at 3, 6, and 12 months.

Obesity disproportionately impacts sexual minority women. Behavioral weight loss programs are the gold standard treatment for mild to moderate obesity. The investigators have developed an online behavioral weight loss program that is effective, low-cost, and highly scalable. However, existing research suggests that tailoring treatment to address 3 well-established weight loss barriers in sexual minority women will be critical for maximizing the relevance and efficacy of behavioral weight loss for this group. In the Preparation Phase of this K23, the investigators developed 3 novel treatment components targeting sexual minority women's weight loss barriers (i.e., minority stress, low social support, and negative body image), the investigators piloted the program among sexual minority women of higher weight, and the investigators conducted individual qualitative interviews to elicit feedback on the intervention's acceptability, cultural relevance, usability, and feasibility, and this feedback was used to refine the program. In the Optimization Phase of this K23 (the current phase), 88 women will receive 12 weeks of Rx Weight Loss and will be randomized to receive 0-3 tailored components in a full factorial design with 23 (8) distinct combinations of components. Novel components that increase mean weight loss (by ≥2%) or the proportion of women achieving clinically meaningful weight loss (by ≥10%) at 6 months will be retained in a finalized obesity treatment package that the investigators will evaluate in a future randomized controlled trial (RCT) (Evaluation Phase). The aims of this study are to: Aim 2A (Optimization): Use a factorial experiment to determine how 3 novel components impact mean weight loss and the proportion of women achieving a 5+% weight loss at 6 months. Aim 2B (Mediation): Clarify how tailored components impact weight loss by testing hypothesized mechanisms of action (i.e., coping with stress, perceived social support, weight and shape concerns). This project will tailor and optimize an evidence-based online behavioral obesity treatment to enhance weight loss outcomes in sexual minority women.

The purpose for this research is to create a MyChart-enabled virtual coach that assists obese patients lose weight prior to ventral hernia surgery. Researchers intend to show how the use of a virtual coach is more effective in preoperative weight reduction prior to ventral hernia repair over usual care. Correspondingly, this may lower unplanned hospital readmissions. For this clinical trial, where randomization is not possible, the study team will implement the use of propensity score matching that sorts individuals into different study arms as if randomly assigned. The primary outcome is the average net amount of time-dependent weight change per group over six months. Secondary outcomes are for the intervention group, patient satisfaction with the virtual coach and for both groups, quality of life. In addition, areas of social and economic disadvantage will be identified that may contribute to higher obesity rates. Machine learning (ML) modeling will be used to determine the important features for weight lost over the course of the study. The impact of this work will be to demonstrate efficacy and realized workflow efficiencies within a hospital-based surgery clinic.

This study is a randomized controlled trial to evaluate the effect of an adapted version of the Body Project program among adult women of higher body weight who want to lose weight. The study will evaluate treatment effects on weight and shape concern and explore the impact of intervention on weight loss outcomes.

This study seeks to answer the fundamental questions of which initial, first-line weight loss intervention should be offered to older adults with obesity and multiple chronic conditions and how to address the high non-response rates observed with most conventional strategies. A sequential, multiple assignment, randomized trial (SMART) design will permit the evaluation of treatment combinations that maximize weight loss and will provide data on constructing a future tailored, adaptive intervention. If successful, these findings will identify interventions that could markedly improve health and quality of life of these older adults, reduce long-term disability, and lower healthcare costs

The goal of this research study is to learn if a home-based physical activity program is feasible and can help endometrial cancer survivors lose weight.

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).
