Filter by:Obesity can severely reduce quality and longevity of life and there is an urgent need to help people lose weight and maintain weight loss long term. Digital behaviour change interventions targeting diet and physical activity have the potential for public health gain; however, these interventions are often not adequately tailored to the participants. The aim of this study is to develop and test a digital intervention to help people make sustainable changes to diet and physical activity, and consequently their weight. This study is a hybrid trial that will evaluate the effectiveness, cost-effectiveness and implementation of the Choosing Health program among overweight/obese adults. This study is a two-group randomised controlled trial (RCT) with within person assessment. Participants (N=285) will be randomly assigned to either the Choosing Health digital intervention or a control group. For intervention participants, Ecological Momentary Assessment (EMA) will be used to identify behavioural determinants for each individual in order to tailor evidence-based behaviour change techniques and intervention content. Control group will receive non-tailored factual weight loss advice. Primary outcome is mean difference in weight loss between groups at 6 months, in kilograms. Key outcomes will be measured at baseline, 3-, 6- and 12 months. Data will be analysed using multilevel modelling and time series analysis. This is the first weight loss intervention applying individualised digital tailoring based on continuous assessment of individual's psychological determinants of behaviour measured over time. The Choosing Health will offer insight into factors associated with success in making sustained changes to weight, and secondary outcomes, such as diet and physical activity.
This is a pilot study evaluating a clinically managed weight loss program. The program consists of a 17-week weight loss program which involves a multidisciplinary team where personalized interventions are given to participants from the team based on the participants goals.
The purpose of this study is to examine the feasibility of two approaches for improving long-term weight loss success among individuals with severe obesity. All participants will receive a 15-week, standard behavioral weight loss program followed by either 8 weeks of a mindfulness self-compassion intervention or 8 weeks of a nutrition and cooking education intervention (determined via randomization procedures). Assessments of weight, physical activity, and other weight-related and psychosocial factors will occur at baseline, 4 months, 6 months, and 9 months.
The purpose of this study is to evaluate the efficacy of cryotherapy on the slimming of subcutaneous fat mass in the abdomen and saddlebags. Cryotherapy is a completely non-invasive method that induces a selective reduction of fat cells by localized and controlled cooling in areas such as the abdomen, flanks, inner knees, inner thighs, back and arms. Adipose tissue is composed of two types of tissue: white and brown adipose tissue. Studies have shown that exposure to cold induces an increase in the number of brown adipocytes (detected by PET/CT-scan) under the effect of the hormone irisin produced by the muscles. In addition, another study has shown that prolonged exposure to cold reduces the size of brown adipocytes leading to thermogenesis, suggesting that cold exposure may contribute to the control of obesity. The freezing technology of this cryotherapy unit allows the temperature of the subcutaneous adipose tissue to move almost instantaneously from -6°C to -10°C, gradually causing the reduction of subcutaneous adipose tissue.
In the United States, the most significant risk factors for endometrial cancer (and EIN) are obesity and metabolic syndrome, given their high prevalence in this population. Given the high survival rate in early stage endometrial cancer, these patients, specifically those that are obese and have metabolic syndrome, are more likely to die of other causes. By treating an obese patient's endometrial cancer, one cause of death may be prevented but an important opportunity is missed to improve overall survival after cancer treatment. Concurrent laparoscopic hysterectomy and weight loss surgery is not an experimental procedure. This combined procedure has successfully been performed at our institution numerous times but there is a lack of data describing clinical outcomes and ideal patient selection. The goal of this study is to assess the feasibility of an expedited referral process for the obese endometrial cancer or EIN patient from her gynecologic oncologist to the Brigham Center for Weight Management and Metabolic Surgery. Secondary outcomes will include short-term and long-term obesity-related outcomes (i.e., better diabetes control, lowered cholesterol, lowered baseline blood pressure) as well as whether quality of life is improved post-operatively compared to preoperatively in concurrent surgery.
The purpose of this study is to estimate the effects of caloric restriction and exercise on body weight, cardiovascular metabolic markers, immune function, and intestinal flora among college students, as well as the underlying mechanisms.
This is a randomized controlled trial to compare intra-gastric injection of Botulinum Toxin A (Botox; Allergan Inc. Irvine, Ca, USA) against non-surgical management for obesity (i.e. exercise/diet). Our hypothesis is that intra-gastric injection of Botox into the fundus and body of the stomach will result in greater weight loss than just exercise and diet alone.
Specific Aim #1: Pilot test a social network-informed CBPR-derived health promotion program for feasibility outcomes with overweight or obese adults from two immigrant communities. Specific Aim #2: Assess the preliminary impact of embedding a social network-informed CBPR-derived intervention within a regional health promotion resource hub on sustainability and uptake outcomes.
The purpose of this research study is to find out whether a primarily self-guided program can produce changes in weight, body fat and cardiovascular risk among young men.
Comprehensive lifestyle interventions are recommended for the treatment of adolescent obesity; however, evidence suggests that they are not as effective in teens as they are in children and adults. Recent evidence supports that shifting the timing of energy intake earlier in the day has led to improved weight loss outcomes among adults with overweight and obesity. Given that adolescents traditionally consume the majority of their daily energy intake late in the day (past 5PM), this approach may improve the effectiveness of traditional behavioral weight control interventions in teens. Therefore, the primary aim of the proposed research is to pilot a novel adaptation of an evidence-based adolescent weight control intervention in which adolescents will be randomized to consume the majority of their daily energy needs earlier versus later in the day. More specifically, 40 adolescents, ages 13-17, with obesity (BMI>95% for age and sex) will be randomized to a 16-week evidence-based weight control intervention that has the participant consume >50 percent of their total energy intake before 3PM (i.e. at breakfast / lunch; BFL) or after 3PM (i.e. dinner; DIN). Assessments will take place at baseline and 16 weeks (post-treatment). The proposed study will test 1) the adherence and feasibility of the BFL vs. DIN interventions as measured by the average number of days on which daily energy was consumed in accordance with the prescribed eating plan and, secondarily, mean session attendance, 2) if the BFL group will have significantly greater reductions in BMI post-treatment as compared to the DIN group, 3) if there are differences in sleep duration and quality between groups, and finally, as an exploratory aim, whether there are differences in dietary quality between groups. The proposed research is significant, as it addresses obesity in teens. It is innovative as the timing of meals and snacks have not been manipulated in adolescents in the context of behavioral weight control. Moreover, the study will shed light on whether doing so improves sleep and could help to untangle how sleep and weight gain relate in adolescents.
