Background: Over 60% of Canadians are overweight or obese and more than half have a history of a mental illness. The COVID-19 pandemic has made it difficult for people living with obesity to manage their weight even after undergoing bariatric surgery. These difficulties in combination with the stress of the pandemic can cause significant declines in mental health and well-being. Psychotherapy ("talk therapy") has been shown to be effective in helping to reduce mental health and disordered eating symptoms in patients managing obesity; however, there is limited data in the context of COVID-19. Objective: This study will examine whether providing a convenient and accessible telephone-based psychotherapy during and potentially after the COVID-19 pandemic will lead to better mental health and disordered eating-related outcomes in patients managing obesity after weight loss surgery. Hypothesis: Relative to the control group, those receiving psychotherapy will have lower mental health distress and eating disorder symptoms. Methods: Participants recruited from 4 weight loss surgery programs across Ontario will be randomly assigned to one of two groups: 1) Control (7 weekly non-structured check-in emails and access to online COVID-19 related mental health resources) or 2) Tele-CBT (a 7-session telephone-based cognitive behavioural therapy [a type of "talk therapy"] intervention focused on developing coping skills and specifically designed for weight loss surgery patients). Participants will complete measures of mental health distress, eating behaviours and a psychological distress scale prior to and immediately following the intervention. Implications: If Tele-CBT is found to improve post-pandemic mental health distress and eating behaviours, it could be routinely offered to patients with other chronic medical conditions as a resource to help manage psychological distress and mental health concerns emerging during and after the COVID-19 pandemic.
A retrospective study to investigate the method called The Halland Obesity Municipal Effort for children. All children participating in the intervention since the start of this specific method will be eligible for inclusion. The aims are to describe participants and the method-specific activities they are participating in, as well as the effect on their health and school grades.
Based on the findings of our formative work, conduct a one-year intervention among African American Adults using revised culturally tailored materials to examine differences in Healthy Eating Index (HEI) and type 2 diabetes (T2DM) risk factors among participants (n=198) randomized to one of the 3 dietary patterns: 1) Healthy U.S.-Style Eating Pattern, 2) Healthy Mediterranean-Style Eating Pattern, and 3) Healthy Vegetarian Eating Pattern.
This is a randomized placebo-controlled trial of semaglutide, an FDA-approved therapy for the treatment of type 2 diabetes mellitus and obesity, in adults with symptomatic asthma despite the use of inhaled steroids and with excess body weight. This study will test the central hypothesis that semaglutide will improve asthma control and reduce airway inflammation due to direct effects on the respiratory tract in adult asthma associated with obesity.
Prader-Willi syndrome (PWS) is a rare and complex genetic disease characterized by hypothalamic-pituitary axis dysfunction combining eating disorders associated with hyperphagia and satiety deficiency, mild intellectual deficit and behavioral disorders. This disease requires continuous management through specific therapeutic education to prevent metabolic and cardiorespiratory complications related to obesity. Physical activity must therefore be regular, adapted to the disability, taking into account cognitive deficits and behavioral disorders. Prader-Willi syndrome (PWS) is a rare and complex genetic disease characterized by hypothalamic-pituitary axis dysfunction combining eating disorders associated with hyperphagia and satiety deficiency, mild intellectual deficit and behavioral disorders. This disease requires continuous management through specific therapeutic education to prevent metabolic and cardiorespiratory complications related to obesity. Physical activity must therefore be regular, adapted to the disability, taking into account cognitive deficits and behavioral disorders. The Unit of Care and Rehabilitation, of the Hôpital Marin d'Hendaye, receives patients with PWS or other obesity from rare causes, at a rate of 1 to 2 annual stays of 1 to 2 months, which allow the regulation of somatic disorders and the initiation of weight loss. However, the difficulty is to keep a stable weight curve between stays. Only 20% of patients over the last 2 years managed to stabilize or decrease their BMI during the 6 months following their hospitalization. The proposed study aims to evaluate an innovative and individualized care program combining Physical activity, Nutrition and therapeutic education for adults with PWS who will be admitted to the hospital for 5 weeks. We hypothesize that this program will allow to stabilize or decrease the BMI of patients at 6 months after hospitalization by inducing a behavioral change in terms of physical activity and eating behavior. We will conduct a randomized controlled trial on 128 patients who will participate in this program, or will benefit from standard care.
This optimization trial will examine three tracking (or "self-monitoring") strategies for weight loss -- tracking dietary intake, steps, and/or body weight -- all delivered through digital health tools. The purpose of the study is to evaluate the combination of these strategies that maximizes 6-month weight loss in the context of a standalone digital health intervention for adults with overweight or obesity. The investigators will recruit 176 total participants to the trial. Recruitment will occur through remote channels. Interested individuals will be directed to an online screening questionnaire; those who are eligible will then be invited to attend an initial remote session with study personnel to ensure interest and eligibility in the study. The weight loss intervention will last 6 months, and all participants will receive a "core" treatment consisting of goal setting, behavioral lessons, action plans, and tailored feedback - all of which will be delivered remotely. Depending on which group participants are assigned to in the study, some individuals will be asked to track their dietary intake, their steps, and/or their body weight via digital tools. All study tasks will occur remotely, thus, participants never need to come in-person for any intervention or assessment tasks. The investigators will use the Multiphase Optimization Strategy (MOST) framework to identify the most effective combination of self-monitoring strategies. The factorial design will allow the research team to determine the unique and combined impact of each self-monitoring component on weight change. The primary outcome is weight change from baseline to 6 months. The research team will also assess self-monitoring engagement over 6 months and its association with weight change. To complement the main trial, the research team will also randomize half of participants to receive an interactive orientation video, in order to assess its impact on trial retention at 6 months. Overall, the information gathered from this trial will enable the construction of an optimized digital health intervention for weight loss that can be delivered remotely, which, if found to be effective, could have high potential for scalability.
Obstructive sleep apnea syndrome (OSA) represents highly prevalent (typically overlooked, undiagnosed and untreated) disorder significantly increasing cardiovascular, cancer and overall mortality as well as increasing the risk of Type 2 diabetes and liver steatohepatitis. Unfortunately, adherence to state-of-the-art therapy with continuous positive airway pressure devices (CPAP) is poorly tolerated by patients, rendering a significant proportion (~60-70 %) of them at undiminished cardiovascular and metabolic risk warranting development of innovative, pharmacological, treatment options. The overarching theme of this project is that metabolic impairments associated with OSA (e.g. Type 2 diabetes mellitus and non-alcoholic steatohepatitis) are causally mediated by elevated levels of circulating free fatty acids (FFA) originating from hypoxia-induced adipose tissue lipolysis. Increased plasma FFA subsequently induce insulin resistance, β-cell dysfunction, increase hepatic glucose output and stimulate lipid storage in liver. The investigators recently proved that hypoxia represents a powerful stimulus for adipocyte lipolysis and that experimental pharmacological inhibition of lipolysis prevented development of Type 2 diabetes in a mouse model of OSA. The goal of the project is to understand adipose tissue lipolysis derangements in OSA subjects and to evaluate the feasibility of lifestyle intervention as a mean to reduce spontaneous lipolysis.
We postulate that childhood traumas are associated with deregulation of the glucocorticoid axis and the inflammatory system in obese women. The main objective of the study is to compare the salivary cortisol awaking response in obese women according to the presence of childhood trauma (assessed using the Childhood Trauma Questionnaire, CTQ).
The investigators describe a protocol for a randomized controlled trial to find out the effect and safety of electroacupuncture on losing weight in obese patients with prediabetes.
