Motivational Interviewing to Promote Healthy Behaviours in Young Adults
ObesityRisk FactorsThe overall goals of this project are to evaluate the feasibility of web-based nurse-led motivational interviewing and educational interventions to promote healthy behaviours for obesity prevention and maintenance of healthy weight and behaviours among young adults attending university (age 18-29) in Hamilton, Ontario. A secondary goal is to evaluate if the intervention is more successful among people at higher risk of obesity (a risk stratification approach). A pilot randomized controlled trial will be conducted. Young adults will be randomized to receive a tailored behavioural intervention through motivational interviewing sessions with a nurse combined with educational materials, or control (educational materials only). Both groups will be followed for 6 months and their weight at baseline and end of the study will be measured. Outcomes related to the feasibility of the intervention and participants' experiences in the study will also be measured.
Community Active and Healthy Families
ObesityChildhoodTo address childhood overweight disparities among Latino children in immigrant families a pilot trial of a community-based obesity treatment program, Community Active and Healthy Families (AHF), among 5-12 year old overweight and obese Latino children in immigrant families using pre/post design will be conducted. The hypothesis is that children participating in Community-AHF will demonstrate a reduction in child body mass index as measured by %BMIp95 (primary outcome) and improved diet physical activity behaviors (secondary outcomes) at intervention completion compared with pre-intervention
Trial of the Combination of Alpha-Lipoic Acid and Mirabegron in Women and in Men With Obesity
Insulin ResistanceObesityBackground: Obesity and related illnesses cause at least 2.8 million deaths each year worldwide. Few treatments exist for obesity that are safe and widely available. A study drug (mirabegron [MG]) combined with a supplement (alpha-lipoic acid [ALA]) may help. Objective: To learn how MG and ALA can help the body process food. Eligibility: People aged 18 to 65 years with a body mass index between 30 and 40 kg/m2. Design: Participants will be screened. They will have a physical exam. They will have blood and urine tests and a test of their heart function. They will speak with a dietician. The study has two phases. Each phase begins with a 2-day stay in the clinic; then the participant will take the study drugs at home for about 4 weeks, followed by another 2-day stay in the clinic. They will also have outpatient visits about 2 weeks after each clinic stay. During the clinic stays, participants will undergo many tests: They will have a plastic tube (catheter) inserted into a vein in each arm. These will be used to draw blood and to infuse glucose (sugar) and insulin. They will have imaging scans. They will have a clear hard plastic shield placed over their head to measure oxygen and carbon dioxide as they breathe. Participants will take the study drugs at home. Both MG and ALA are taken by mouth with water. During one phase, participants will take MG plus a placebo. A placebo looks like the study drug but doesn t contain medicine. They will log their diet, exercise, and sleep....

Exploring the Familial Reach of Adolescent Obesity Treatment
Pediatric ObesityAn observational study ancillary to the randomized clinical trial (RCT) TEENS+ (R01HD095910), a family-based lifestyle intervention, for adolescents with obesity, to determine: 1) if family-wide changes to the shared home environment are implemented, 2) if ripple effects to untreated family members are observed, and 3) whether these changes are predictive of adolescents' weight management success. Funding support from NIH via R21HD105906.
BariaPSY: The Data Bank
Bariatric Surgery CandidateObesityMultimorbidity, the co-occurrence of several chronic conditions, is a growing phenomenon that poses new challenges for clinicians and researchers. The association between a mental health disorder and a physical health disorder represents a particularly frequent subtype of multimorbidity and is associated with greater severity and higher consumption of care. It is essential and urgent to explore the specific pathophysiology of this subtype of multimorbidity in order to develop adapted therapeutic strategies. Psychiatric disorders, such as mood disorders, anxiety disorders, attention deficit disorder and binge eating disorder, are common in people with obesity. For example, although most of these disorders may improve after bariatric surgery, some components of these disorders, such as emotional dysregulation and impulsivity, need to be addressed as they appear to be involved in the development of addiction and suicidality after bariatric surgery. Therefore, screening and vigilance of these risks appear increasingly necessary. To address this challenge, the BariaPsy databank aims to explore the screening of certain mental health disorders frequently observed in adults with obesity through an innovative approach that explores behaviors in the form of dimensions. It will help clinicians to quickly identify markers of certain disorders, thus helping them to further investigate the problem and provide personalized resources to their patient.
Does a Virtual Coach Offer a Better Solution for Weight Reduction in Ventral Hernia Patients With...
ObesityVentral HerniaThe 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.

Biological Sample Repository for Gastrointestinal Disorders
ObesityObesity18 moreThe goal of this observational study has the purpose of collecting biological samples from obese patients undergoing evaluation for weight loss by means of medical or endoscopic therapies; and of post bariatric surgery patients presenting with short- and long-term surgical complications. The aim is to enhance the overall understanding of the mechanisms leading to obesity, weight loss, failure to lose weight, and weight regain following treatment. Additional goals are to determine the efficacy of endoscopic and surgical procedures, to identify potential therapeutic targets and disease biomarkers that predict response to therapy.
Early vs. Late Time Restricted Eating vs. Daily Caloric Restriction
Overweight and ObesityThe goal of this clinical trial is to learn about time restricted eating as a weight loss intervention in adults with obesity. The main questions it aims to answer are: How does the timing of the eating window (early vs late time restricted eating) affect weight loss and changes in metabolic risk factors? How does time restricted eating compare to standard of care (daily caloric restriction) for weight loss and changes in metabolic risk factors? Participants will be randomly assigned to either early time restricted eating, late time restricted eating, or daily caloric restriction. They will be asked to follow the assigned dietary strategy for 1 year and will receive a group-based program for instruction and support. They will be asked at several times during the year to have their weight and body composition measured, provide blood samples, track their food, and wear monitors for physical activity and sleep.
