Filter by:The study is a single site parallel randomized controlled study. The study will be assessing the effect of a 10% pre-conceptional weight loss intervention vs a control group among healthy couples where the prospective mother is pregnant and overweight or obese (BMI 27-44.9 kg/m^2). The couples in intervention group will receive dietitian counseling and participate in physical activity sessions to attain the 10% weight loss. The overall objective is to test whether a comprehensive pre-conceptional parental weight loss intervention effectively reduces the risk of offspring overweight, and adiposity and its complications compared to a control group.
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.
The study will evaluate the effect of an existing hospital-based obesity treatment in children and adolescents in relation to weight loss and motivation. This is to ensure that children who have developed obesity have the possibility to obtain a healthier lifestyle, including a healthier body weight during their school years. This study will test whether an obesity treatment program designed for school children can reduce the degree of overweight in children and adolescents with overweight and obesity.
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.
Gastric myoelectric, inflammatory, and hormonal responses, body compositional, energy expenditure, and metabolic changes during the development of obesity and the weight loss process are underinvestigated. This project studied the myoelectrical inflammatory and hormonal responses of the stomach, in addition to energy expenditure and body composition changes during weight loss via bariatric surgery and lifestyle intervention.
Beta-amino isobutyric acid (BAIBA) is a myokine produced in skeletal muscle and has been shown to impact how our body metabolizes fuel. We seek to examine changes in body composition, weight loss, glucose control, and cardiometabolic risk factors after adding supplementation of BAIBA to exercise in overweight and obese men and women.
The goal of this intervention study is to examine changes in body composition, weight loss, and cardio-metabolic risk factors after adding supplementation of L-Beta aminoisobutyric acid (L-BAIBA) and Grains of Paradise to exercise in overweight and obese men and women. Participants will supplement for 8 weeks and complete a 8 week exercise protocol.
Abstract Introduction: This pilot study will determine the recruitment feasibility, retention, and adhesion for a motivational interviewing program for weight loss in adults according to the processes of change in weight loss. Methods and Analysis: The single-arm pilot study will be a feasibility study of the Motivation to Lose Weight version 1 (MLW v.1). The study includes presential and online sessions. Participants will be recruited through advertisements on social media and selected according to the inclusion criteria. Participants will receive 8 sessions of approximately 30-45 minutes of motivational interviewing (MI) according to the processes of change in weight loss, as measured by the S-Weight scale. The results will be evaluated at the beginning and the end of the program, which will last 8 weeks. The primary outcome of the study is feasibility. The intervention will be feasible if adherence to the proposed activities in the sessions is greater than 70%, we can recruit 10 patients within 8 weeks, the proportion of interested people and registered participants is greater than 30%, and more than 75% of participants attend the final study visit. The secondary outcome is weight loss, fat mass percentage, muscle mass, waist and hip measurements, and the scores of behavioral scales. Ethics and discussion: The feasibility of this project consists of proposing an individualized intervention based on MI strategy(s) for each participant, according to the stage of readiness, and thus, help to evolve in the process of losing weight. This intervention aims to increase the participant's confidence level to implement actions that lead to the progression of behavior and, consequently, the action and maintenance of the lost weight. This study was approved by the Research Ethics Committee (REC) of the Hospital de Clínicas de Porto Alegre (HCPA) under number 20220209 CAAE 59573622300005327.
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.
