Filter by:The study is a single site parallel randomized controlled study. The study will be assessing the effect of approximately 10% weight loss intervention vs a control group among healthy females/couples where the prospective mother is overweight or obese (BMI 27-45 kg/m^2) and between 18-38 years. The investigators will recruit a total of 240 healthy females/couples who will be randomized 1:1 to either intervention or control, stratified according to maternal pre-pregnancy BMI. 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 investigators hypothesize that parental weight loss intervention, initiated before conception, will facilitate lower parental insulin resistance, inflammation, body weight and adiposity, incretin responses compared to usual care. For the offspring the investigators hypothesize that the intervention will reduce adverse pregnancy outcomes with a reduction in offspring neonatal adiposity, reduced risk of being born large for gestational age (LGA) and with lower BMI z-score at 18 months.
The purpose of this study is to assess whether providing a parent-only group program before providing a parent and child group program works better than the parent and child group program alone.
One-in-four Canadians will be diagnosed with an abnormal heart rhythm called atrial fibrillation (AF) in their lifetime. This is expected to double by 2050, owing to an aging population and increased age- and health behaviour-associated AF risk factors (e.g., poor cardiorespiratory fitness, Type II diabetes, hypertension, and obesity). AF is associated with an increased risk of severe health outcomes including stroke, heart failure, dementia, and death. Nearly three-quarters of people with AF also have obesity (excess body weight). According to research, people with obesity that lose approximately 10% of their body weight can experience relief from uncomfortable AF symptoms. Losing weight may even help people return to a normal heart rhythm. Cardiac rehabilitation (CR) is a proven way to help people with heart disease live longer, healthier lives. So far, research has not shown whether CR helps improve the abnormal heart rhythms seen in AF. This may be because CR programs usually do not offer specific help with weight management. Therefore, adding behavioural weight-loss treatment (BWLT; group classes to change thoughts and behaviours to encourage weight loss) to CR programs may help people with AF and obesity experience relief from their symptoms. This randomized controlled trial will assess whether the combination of an AF-specific 'small changes' BWLT and traditional CR results in a greater proportion of patients with AF and obesity achieving ≥ 10% body weight loss compared to patients who receive standard care (traditional CR alone). Traditional CR consists of participating in exercise sessions, supervised by health professionals, twice per week for 12 weeks. In addition to traditional CR, patients that are randomized to receive BWLT will attend 12 weekly online group therapy classes to learn strategies from psychology to help encourage weight loss. The investigators will collect data pertaining to weight, AF burden, physical activity, and disease-specific and generic patient-reported outcomes. This information will determine if taking CR+BWLT helps patients with weight loss and AF symptoms. Further, it will help efforts to provide effective treatment to patients with AF to help participants lose weight and reduce or eliminate AF symptoms.
This is a 4-month randomized trial of a prolonged nightly fasting intervention (PROFAST) in 40 overweight and obese individuals with monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and smoldering waldenstrom macroglobulinemia (SWM). The purpose of this study is to understand if fasting for a prolonged period of time during the nighttime hours is a strategy to prevent overweight and obese individuals from developing blood cancer. Participants will be randomized into the following two groups: - Group A: PROFAST intervention for 4 months - Group B: Healthy Lifestyle Control group for 4 months
The purpose of this study is to conduct a five-arm pilot and feasibility trial in healthy, young individuals without obesity to evaluate the feasibility and efficacy of dietary intervention approaches to slow mechanisms of aging.
In the Time-Restricted Eating: Microbiome and Bone (TREMBO) study, the primary goal is to determine the effect of time-restricted eating with caloric restriction compared to caloric restriction alone on body weight, the gut microbiota, and bone health in older women who are overweight or obese.
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).
Pregnancy and delivery are major stressors on the female body and contribute significantly to permanent weight gain and associated morbidity in women. This can profoundly affect the ability of active duty (AD) women to advance in their career. The first 12 weeks postpartum are the time period during which the most significant weight loss occurs and is critical in achieving a healthy weight in the first year postpartum. Many factors contribute to effective weight loss in this period among which the most critical are diet, exercise, and sleep. Breast feeding and depression may also affect weight changes postpartum. Research has shown diet to likely be the most crucial of these factors. The PADaWL study is designed as a randomized controlled trial to assess the effects of dietary intervention on weight and physical fitness versus routine postpartum care in the first year postpartum. Subjects will be primiparous AD women from any military service recruited in the obstetric clinic in the third trimester of pregnancy at Tripler Army Medical Center. Data will collected in an ambi-directional fashion with pre-pregnancy physical fitness data, demographic and pregnancy data collected at time of enrollment. Subjects will be randomized to receive intensive virtual sessions with a dietician vs routine postpartum care for the first 12 months postpartum. We will utilize a biometric device to monitor activity levels and sleep, web-based diaries to monitor breast feeding and diet, and validated questionnaires to evaluate depression as well as diet and sleep. Subjects will be monitored weekly for the first 12 weeks postpartum and will then be further evaluated at 6, 9 and 12 months postpartum. Primary outcome is weight at 12weeks postpartum and whether subjects have achieved military standards. Secondary outcome will be weight at 12 months postpartum and whether subject has achieved weight and fitness standards. The study intends to collect large amounts of data, and we intend to analyze which factors may be contributing to weight retention postpartum. This study should provide an accurate assessment of the effects of pregnancy on AD women. It should generate a clean and accurate dataset on which multiple follow-on studies can be performed and provide data for designing further intervention studies in postpartum women. The results of this study should also be able to assist in developing policy and guidance concerning AD women and pregnancy.
Unintentional weight loss (UWL) is commonly associated with a wide variety of diseases and there is still no valid diagnostic pathway for evaluating UWL. When detecting UWL coupled with GRAIL Galleri testing, (an investigational pan-cancer early detection test), it is thought that there is a greater positive predictive value in detecting malignancies. This study aims to test the potential synergistic effects of UWL detection and GRAIL usage to detect malignancy at an even earlier rate. UWL will be measured using weekly weight tracking.
Rationale: Investigate if there is a significant weight reduction expressed in total body weight loss percentage (%TBWL) in patients 5 years after surgery, whom underwent a mini gastric bypass (MGB-OAGB) with addition of the implantation of a MiniMizer Ring. Study design: A prospective non blinded single centre randomized controlled trial. Sudy population: The study population will exist of patients eligible for MGB-OAGB surgery. Patients are invited to participate if Body Mass Index (BMI) ≥ 35kg/m2 with a comorbidity related to morbid obesity, or a BMI exceeding 40kg/m2. Intervention: Insertion of the MiniMizer Ring around the gastric pouch in addition to the 'standard' MGB-OAGB. Main study parameters/endpoints: Primary Objective: 1. %TBWL 5 years after surgery. Secondary Objectives: 2. Percentage Excess Weight Loss (%EWL) 5 years after surgery. 3. Decrease or reduction of comorbidities (diabetes mellitus, hypertension, hyperlipidemia, sleep apnoea, and joint complaints). 4. Improvement of quality of life: SF-36 and OBESI-Q questionnaires. 5. Incidence and severity of dumping syndrome. 6. Incidence and severity of reflux symptoms: GERD-HRQoL questionnaire. 7. Incidence and complications due to silicone band. Measurement of objectives are before surgery and six times after surgery combined with the standard postoperative care for patients who undergo bariatric surgery: Expected advantages of bOLGB versus OLGB: 1. Increase of weight reduction, and due to that decrease of comorbidities and/or mortality related to overweight. 2. Long term decrease of weight regain. 3. Decrease of incidence of dumping. Possible disadvantages of bOLGB versus OLGB: 1. Band-related complications such as erosion, infection, stenosis, or pouch dilatation. 2. Functional gastro-intestinal complains such as dysphagia and reflux.
